The use of any cut-off

machine may be

hazardous. Because a

cut-off machine is a

high-speed, fast-cutting

power tool, special safety precautions

must be observed to reduce the risk of

personal injury and fire.

It is important that you read, fully under-

stand and observe the following safety

precautions and warnings.

Read the Owner’s

Manual and the safety

instructions periodically.

Careless or improper use of any

cut-off machine may cause serious or

fatal injury.

Have your STIHL dealer show you

how to operate your cut-off machine.

Observe all applicable local safety

regulations, standards and ordinances.

:DUQLQJ

Minors should never be allowed to use a

cut-off machine. Bystanders, especially

children and animals should not be

allowed in the area where a cut-off

machine is in use. Never let the cut-off

machine run unattended.

Do not lend or rent your cut-off machine

without the Owner’s Manual. Be sure

that anyone using your cut-off machine

understands the information contained

in this manual. Employers should estab-

lish a training program for operators of

gasoline powered, hand held portable,

cutt-off machines to assure safe oper-

ation of these machines. These safety

precautions and warnings apply to the

use of all STIHL CutquiksTM.

Different models may have different

parts and controls. See the appropriate

section of your owner’s manual for a

description of the controls and function

of the parts of your model cut-off

machine.

Safe use of a cut-off machine involves

- the operator

- the cut-off machine

- the use of the cut-off machine.

7+(23(5$725

3K\VLFDO&RQGLWLRQ

You must be in good physical condition

and mental health and not under the

influence of any substance (drugs.

alcohol, etc.) which might impair vision,

dexterity or judgement. Do not operate a

cut-off machine when you are fatigued.

Be alert - if you get tired while operating

your cut-off machine, take a break, tired-

ness may result in loss of control.

Working with any cut-off machine can be

strenuous. If you have any condition that

might be aggravated by strenuous work,

check with your doctor before operating

a cut-off machine.

:DUQLQJ

Prolonged use of cut-off machines (or

other machines) exposing the operator

to vibrations may produce whitefinger

disease (Raynaud’s phenomenon) or

carpal tunnel syndrome. These

conditions reduce the hand’s ability to

feel and regulate temperature, produces

numbness and burning sensations and

cause nerve and circulation damage and

tissue necrosis. All factors which contri-

bute to whitefinger disease are not

known, but cold weather, smoking and

diseases or physical conditions that

affect blood vessels and blood transport,

as well as high vibration levels and long

periods of exposure to vibration are

mentioned as factors in the development

of whitefinger disease. In order to

reduce the risk of whitefinger disease

and carpal tunnel syndrome, please

note the following:

- Most STIHL cut-off machine models

are available with an anti-vibration

("AV") system designed to reduce

the transmission of vibrations

created by the engine to the

operator’s hands. An AV system is

recommended for those persons

using cut-off machines on a regular

or sustained basis.

- Wear gloves and keep your hands

warm.

- Keep the AV system well maintained.

A cut-off machine with loose

components or with damaged or

6DIHW\3UHFDXWLRQV

76

worn AV buffers will tend to have

higher vibration levels.

- Maintain a firm grip at all times, but

do not squeeze the handles with

constant, excessive pressures, take

frequent breaks.

All the above mentioned precautions do

not guarantee that you will not sustain

whitefinger disease or carpal tunnel

syndrome. Therefore continual and

regular users should monitor closely the

condition of their hands and fingers.

If any of the above symptoms appear,

seek medical advice immediately.

3URSHU&ORWKLQJ

Clothing must be sturdy

and snug-fitting, but allow

complete freedom of

movement. Avoid loose-

fitting jackets, scarfs,

neckties, jewelry, flared or cuffed pants,

unconfined long hair or anything that

could become caught on any obstacles

or moving parts of the unit. Wear over-

alls or long pants to protect your legs.

Do not wear shorts.

:DUQLQJ

When cutting metal, a cut-off machine

generates sparks which can ignite

clothing. Most fabrics used in clothing

are flammable - even flame retardant

fabrics will ignite at higher temperatures.

To reduce the risk of burn injury STIHL

recommends wearing clothing made of

leather, wool, flame-retardant treated

cotton or a tightly woven, heavier cotton

such as denim. Some flame-retardant

synthetic fabrics are also suitable but

others such as polyester, nylon, rayon

and acetate can melt during fire into a

tar-like matter that burns into the skin.

Keep clothing free of oil, fuel, grease

and other flammable substances.

Protect your hands with

gloves when handling the

cut-off machine.

Heavy-duty, nonslip

gloves improve your grip

and protect your hands.

Good footing is most im-

portant in cut-off machine

work.

Wear sturdy boots with

nonslip soles. Steel-toed

safety boots are recommended.

:DUQLQJ

Loose objects may be thrown toward the

operator by the cutting tool.

To reduce the risk of

injury to your eyes never

operate a cut-off machine

unless wearing goggles

or properly fitted safety

glasses with adequate top and side

protection complying with ANSI Z 87.1.

Proper eye protection is a must.

Wear an approved safety hard hat to

protect your head. cut-off machine noise

may damage your hearing.

Always wear sound barriers (ear plugs

or ear mufflers) to protect your hearing.

Regular users should have their hearing

checked regularly.

:DUQLQJ

Use of this product to cut

masonry, concrete, metal

and other materials can

generate dust, mists and

fumes containing

chemicals known to cause serious or

fatal injury or illness, such as respiratory

disease, cancer, birth defects or other

reproductive harm. If you are unfamiliar

with the risks associated with the particu-

lar material being cut, review the material

safety data sheet and/or consult your

employer, the material manufacturer/-

supplier, governmental agencies such

as OSHA and NIOSH and other sources

on hazardous materials. California and

some other authorities, for instance,

have published lists of substances

known to cause cancer, reproductive

toxicity, etc.

Control dust, mist and fumes at the

source where possible. In this regard

use good work practices and follow the

recommendations of the manufacturer/-

supplier, OSHA/NIOSH, and occupatio-

nal and trade associations. A water

attachment kit is available for your cut-off

machine and should be used for dust

suppression when wet cutting is feasible.

When the inhalation of dust, mists and

fumes cannot be eliminated, the operator

76 

and any bystanders should always wear

a respirator approved by NIOSH/MSHA

for the material being cut.

:DUQLQJ

Cutting masonry, concrete and other

materials with silica in their composition

may give off dust containing crystalline

silica. Silica is a basic component of

sand, quartz, brick clay, granite and

numerous other minerals and rocks.

Repeated and/or substantial inhalation

of airborne crystalline silica can cause

serious or fatal respiratory diseases,

including silicosis. In addition, California

and some other authorities have listed

respirable crystalline silica as a sub-

stance known to cause cancer. When

cutting such materials, always follow the

respiratory precautions mentioned

above.

:DUQLQJ

Breathing asbestos dust is dangerous

and can cause severe or fatal injury,

respiratory illness or cancer. The use

and disposal of asbestos-containing

products have been strictly regulated by

OSHA and the Environmental Protection

Agency. Do not use your cutting-off

machine to cut or disturb asbestos,

asbestos-containing products, or pro-

ducts such as pipes which are wrapped

or covered with asbestos insulation. If

you have any reason to believe that you

might be cutting asbestos, immediately

contact your employer or a local OSHA

representative.

:DUQLQJ

Never modify a cut-off machine in any

way. Only attachments supplied by

STIHL or expressly approved by STIHL

for use with the specific STIHL cut-off

machine models are authorized.

Although certain unauthorized attach-

ments are useable with the STIHL

powerhead, their use may, in fact be

extremely dangerous.

:DUQLQJ

Dust may collect on the powerhead,

especially around the carburetor and

may collect gasoline resulting in danger

of fire. Clean dust from the powerhead

regularly.

$EUDVLYHZKHHOV

:DUQLQJ

Before assembling your cutting wheel

make sure that the maximum operating

wheel speed is above or equal to the

spindle speed of your cut-off machine as

provided in the Specifications of this

manual.

Abrasive wheels for free-hand cutting

are subjected to particularly high

bending and compressive stresses.

:DUQLQJ

Unauthorized wheels may shatter or

break. Use only STIHL wheels or other

authorized wheels with approved RPM

ratings.

Inspect the abrasive

wheel frequently and

replace immediately if the

abrasive wheel is cracked

or warped. Cracked or

warped wheels may shatter or break

and cause serious personal injury.

Out-of-round or unbalanced abrasive

wheels increase vibration and reduce

the service life of the cut-off machine.

Use STIHL wheels approved for this unit.

Abrasive wheels are heat sensitive.

Always store your cut-off machine in a

place where the cutting wheel is not

exposed to direct sunlight or other

sources of heat. Store spare cutting

wheels in a dry place where there is no

risk of frost damage. Failure to follow

these directions may cause the wheel to

shatter or crack in use causing serious

or fatal injury.

76

:DUQLQJ

Never use carbide-tipped, wood-cutting

or circular saw blades. They can cause

severe personal injury from reactive

forces, blade contact or thrown objects.

Your STIHL dealer stocks a range of

special abrasive wheels for the many

applications of the cut-off machine.

:DUQLQJ

Use of the wrong abrasive wheel or

material for which it was not designed

may cause that wheel to shatter causing

serious or fatal injury.

Only use the abrasive wheel approved

for the type of material to be cut. There

are different abrasive wheels each

specially marked, for example:

1. Stone

Also can be used for concrete,

masonary, reinforced concrete

and brick cutting.

2. Steel

Can be used for all ferrous metal

cutting.

3. Asphalt

Also can be used for aggregate

concrete cutting.

4. Ductile iron

Also can be used for certain grades

of cast iron (SG 17-24), bronze and

copper cutting.

For cutting composite materials please

ask your STIHL dealer.

'LDPRQGDEUDVLYHZKHHOV

Diamond abrasive wheels have a much

better cutting performance than the

abrasive wheels. The wheels are steel

centered and diamond particles are

imbedded in their cutting edges.

They can be used for concrete, asphalt,

natural stone, clay pipe, brick and the

like.

They are not suitable for cutting metal or

other materials.

Wet or dry cutting is possible. With wet

cutting you get a longer life of your

wheel. Water attachments are available

for your STIHL cut-off machine.

See the appropriate section of your

owner’s manual.

:DUQLQJ

Do not remount a used diamond

abrasive wheel without first inspecting

for under-cutting, flatness, core fatigue,

segment damage or loss, signs of

overheating (discoloration) and possible

arbor hole damage.

Check the wheel for cracks and make

sure that no pieces have broken off the

wheel before use.

Always fit the wheel so that the arrow on

the wheel points in direction of the

rotation of the spindle.

:DUQLQJ

Always stop the engine before putting a

cut-off machine down or carrying it. The

abrasive wheel continues to rotate for a

short while after the throttle trigger is

released (flywheel effect). Carrying a

cut-off machine with the engine running

is extremly dangerous. Accidental

acceleration of the engine can cause the

wheel to rotate. Avoid touching the hot

muffler.

By hand: When carrying your cut-off

machine by hand, the engine must be

stopped and the cut-off machine must

be in the proper position. Grip the front

handle and place the muffler at the side

away from the body.

:DUQLQJ

Always protect the cutting wheel from

hitting the ground or any other objects.

Damaged wheels may shatter and

cause serious or fatal injury.

For assembly, follow the procedure

described at the appropriate section of

your owner’s manual.

Before operation of your cut-off machine

be sure the controls (e.g. throttle trigger,

stop switch.) and the safety devices are

working properly, the carburetor idle and

maximum speed are correctly adjusted,

and the wheel guard is in place and

securely fastened to your unit.

All wheels should be carefully inspected

for good condition before mounting.

Adjust the wheel guard so

that sparks, dust and cut

material are deflected

away from the operator,

and cannot reach

flammable surroundings. See operating

instructions of your owner’s manual.

Never operate a cut-off machine that is

damaged, improperly adjusted or not

completely and securely assembled.

Inspect for safety in operation.

Proper tension of the V-belt is important.

In order to avoid a false setting the

tensioning procedure must be followed

as described in your Manual. Always

make sure the hexagonal collar nuts for

the cast arm are tightened securely.

Check V-belt tension after one hour of

operation and correct if necessary.

The STIHL TS 350 and TS 360

CutquikTM is supplied with a fuel filler

elbow connector to facilitate easier

refueling. Always keep the connector

and fuel filler cap tightened and properly

sealed. A loose or improperly seated

connector or cap may vibrate loose

during operation causing fuel spillage

which may result in a fire which can

cause serious or fatal injury. Never

operate the unit with a cracked, broken

or improperly seated or adjusted filler

neck. This could permit fuel leakage and

lead to fire. Do not fill tank above the

threefourths level of the neck entry

diameter into the tank. Do not fill tank

above the "max" line on the fuel filler

elbow. Overfilling reduces the room in

the tank for fuel expansion and may lead

to fuel spillage through the tank vent and

risk of fire.

)XHOLQJ

Your STIHL cut-off machine uses an

oil-gasoline mixture for fuel (see chapter

"Fuel" of your owner’s manual).

:DUQLQJ

Gasoline is an extremely

flammable fuel. If spilled or

ignited by a spark or other

ignition source, it can cause

fire and serious burn injury

or property damage. Use extreme cau-

tion when handling gasoline or fuel mix.

Do not smoke or bring any fire or flame

near the fuel.

)XHOLQJ,QVWUXFWLRQV

Fuel your cut-off machine in well-ventila-

ted areas, outdoors only.

Always shut off the engine and allow it to

cool before refueling. Relieve fuel tank

pressure by loosening the fuel cap

slowly.

Select bare ground for fueling and move

at least 10 feet (3 m) from fueling spot

before starting the engine. Wipe off any

spilled fuel and check for leakage.

:DUQLQJ

If fuel gets spilled on clothes, especially

trousers, it is very important to change

clothes immediately. Do not rely upon

evaporation. Flammable quantities of

fuel may remain on clothes after a spill

for longer than expected. Cutting metal

with cut-off machine when clothes are

wet or damp from gasoline is extremely

dangerous as the operator’s clothes

76

might catch fire and cause serious or

fatal injury.

Always make sure that the fuel cap is

tightened securely. Check for fuel

leakage while refueling and during

operation. If a fuel leak is suspected,

do not start or run the engine until leak is

fixed and spilled fuel has been wiped

away.

:DUQLQJ

Unit vibrations can

cause an improperly

tightened fuel cap to

loosen or come off and

spill quantities of fuel.

In order to reduce risk of fuel spillage

and fire, tighten fuel cap by hand with as

much force as possible.

The screw driver end of the STIHL

combination wrench or other similar tool

can be used as an aid in tightening

slotted fuel caps.

6WDUWLQJ

:DUQLQJ

Your cut-off machine is a one-person

tool. Do not allow otherpersons to be

near the cut-off machine. Start and

operate your cut-off machine without

assistance. For specific starting instruc-

tions, see the appropriate section of your

owner’s manual.

Do not drop start. This method is very

dangerous because you may loose

control of the cut-off machine.

Place the cut-off machine on firm ground

or other solid surface in an open area.

Maintain a good balance and secure

footing. Be absolutely sure that the

cutting wheel is clear of you and all other

obstructions and objects, including the

ground; because when the engine starts

at starting-throttle, engine speed will be

fast enough for the clutch to engage

V-belt pulley and turn the wheel. Never

attempt to start the cut-off machine

when the abrasive wheel is in a cut.

When you pull the starter grip, don’t

wrap the starter rope around your hands.

Do not allow the grip to snap back, but

guide the starter rope slowly back to

permit the rope to rewind properly.

Failure to follow this procedure may

result in injuries to hand or fingers and

may damage the starter mechanism.

Always stop the engine and be sure the

wheel has stopped rotating before

setting down the cut-off machine.

:RUNLQJ&RQGLWLRQV

Operate the cut-off machine under good

visibility and daylight conditions only.

:DUQLQJ

Your cut-off machine

produces poisonous

exhaust fumes as soon

as the combustible

engine is running. These

gases (e.g. carbon monoxide) may be

colorless and odorless.

To reduce the risk of serious or fatal

injury from breathing toxic fumes, never

run the cut-off machine indoors or in

poorly ventilated locations. Ensure

proper ventilation when working in

trenches or other confined areas.

002BA058 KN

76 

Never use the cut-off machine with one

hand. Your STIHL cut-off machine is

designed for hand-held use or operation

on a cut-off machine cart. Cutting with

your cut-off machine resting on the

ground or other surface can cause

excessive wear to the bracket designed

to protect the bottom of the tank

housing. Loss of fuel and personal injury

from fire may result. Replace damaged

or badly worn brackets immediately.

Grip: Always hold the cut-off machine

firmly with both hands when the engine

is running. Place your left hand on front

handle bar and your right hand on rear

handle and throttle trigger.

Left-handed users should follow this

instruction too.

Wrap your fingers tightly around the

handles, keeping the handles cradled

between your thumbs and forefingers.

Make sure your cut-off machine handles

and grip are in good condition and free

of moisture, pitch, oil or grease.

Avoid standing in direct line with the

wheel.

:DUQLQJ

Take extreme care in wet and freezing

weather (rain, snow, ice). Clear the area

where you are working.

:DUQLQJ

Avoid stumbling on obstacles and watch

out for holes or ditches. Be extremely

cautious when working on slopes or

uneven ground.

:DUQLQJ

Never operate the cut-off machine with

the starting-throttle lock engaged as this

does not permit proper control of the

speed of the unit and may lead to

serious injury.

:DUQLQJ

Sparks from cutting metal

can burn or cause cloth-

ing to catch fire. Don’t use

a cut-off machine on flam-

mable ground. Always direct sparks

away from the operator or any flamm-

able surroundings.

:DUQLQJ

To reduce the risk of injury from fire,

do not cut into any pipe, drum or other

container without first insuring that it

does not contain volatile or flammable

substance.

The wheel guard is adjustable. It is

extremely important that the wheel

guard is in place and set to suit the type

of work and your stance. The guard

should always be adjusted so that the

user is not endangered by particles of

the material being cut, sparks or pieces

of damaged wheels either directly or by

ricochet. Failure to follow this instruction

could result in serious or fatal injury.

The ideal working speed of the cut-off

machine depends on many factors, e. g.,

the material being cut, the type and

quality of the cutting wheel.

It is essential to determine the direction

of the cut exactly before applying the

abrasive wheel to the work. Wheels are

constructed for UDGLDOpressure only.

/DWHUDO pressure must be avoided.

Check for cracks and make sure that no

pieces have broken off from the wheel

when it is stopped.

Check the wheel guard for cracks. If you

discover any cracks, fit a new guard.

:DUQLQJ

Hold the cut-off machine steady. Do not

change the direction of the cut during

the cut as this may produce a high

torsional load on the abrasive wheel and

may cause it to break or shatter.

To achieve a clean and efficient cut, pull

the abrasive wheel across the work or

move it "to and fro" in the cutting

direction. Do not use force to push the

abrasive wheel into the work.

Insert the wheel into the material only as

deep as necessary to make the cut.

To reduce the amount of dust created,

do not cut all the way through stone and

concrete materials - leave a thin piece

uncut. For most such materials, this

piece can be easily broken afterwards.

Do not cock, jam or wedge the wheel in

the cut.

:DUQLQJ

Do not use abrasive wheels for rough

grinding. Large bending stresses occur

during such work and abrasive wheels

may shatter or break and could cause

serious or fatal injury.

If a cut-off machine cart is used, sweep

debris from the path of the wheels as

such may cause flexing of the abrasive

wheel. This would result in high frictional

forces and thus greatly reduce the

engine power available for the actual

cutting work.

Always use the cart to cut in a straight

line.

:HWFXWWLQJZLWKDEUDVLYHZKHHOV

When cutting masonry with a water

attachment:

1. Make certain water does not flow on

wheel that is not running, since the

wheel will absorb water and that will

affect wheel balance.

2. Shut water off before wheel stops

so that excess water will be

dissipated.

3. Be certain water is applied to both

sides of wheel, since uneven

distribution can cause "one sided"

wear with possible wheel breakage.

4. Use these wheels up the same day.

Do not store and reuse a wheel that

has been used with water.

,PSRUWDQW$GMXVWPHQWV

At correct idle speed, wheel should not

turn. For direction to adjust idle speed,

see the appropriate section of your

owner’s manual.

Do not use a cut-off machine with incor-

rect idle speed adjustment. The rotating

wheel may cause injury.

Have your STIHL dealer check your

cut-off machine and make proper

adjustments or repairs.

Never touch a rotating wheel with your

hand or any part of your body.

5HDFWLYHIRUFHV

:DUQLQJ

Reactive forces may occur at any time

the cutting wheel on at cut-off machine

is rotating. If the wheel is slowed or

stopped by frictional contact with any

solid object or by a pinch, reactive forces

may occur instantly and with great force.

76 

These reactive forces may result in the

operator losing control of the cut-off

machine, which may, in turn, result in

serious or fatal injury.

An understanding of the causes of these

reactive forces may help you avoid loss

of control. Reactive forces are exerted in

a direction opposite to the direction in

which the wheel is moving at the point of

contact or pinch.

Pull-away, climbing and rotational

forces.

The most common reactive forces are

pull-away and climbing. If the contact is

at the bottom of the wheel, a cut-off

machine will try to pull away from the

operator (pull-away). If the contact is at

the front of the wheel, the wheel may

attempt to climb the object being cut

(climbing). If the wheel is severely

pinched at the front, the wheel may be

instantly thrown up and back towards

the operator with a great force in a

rotational motion. The greater the force

generated, the more difficult it will be for

the operator to control the cut-off

machine. Any of the reactive forces can,

in some circumstances, cause the

operator to lose control of a cut-off

machine, allowing the rotating wheel to

come into contact with the operator.

Severe personal injury or death can

result.

Use only cutting attachment authorized

by STIHL. 1HYHUuse chipped abrasive

wheels, circular saw blades, carbide

tipped blades, rescue blades or wood-

abrasive or toothed blades of any nature

on a cut-off machine. The use of such

wheels or blades will greatly increase

the risk of loss of control and severe

personal injury or death from reactive

forces, since the chipped section of an

abrasive wheel, or the teeth of a saw

blade may catch in the material being

cut and generate substantially greater

reactive forces.

Cut-off machines are designed for use

with abrasive wheels in good condition

RQO\Machines designed for use with

wood-abrasive or other toothed blades

use different types of guarding systems

which provide the protection neccessary

for those types of blades. Machines,

such as a cut-off machine, which are

designed for use with abrasive wheels,

require a different guarding system

which is not designed to provide protec-

tion against all dangers presented by

circular saw blades, carbide-tipped

blades, rescue blades or wood-abrasive

or toothed blades of any nature.

:DUQLQJ

To reduce the risk of injury from loss of

control or from the shattering of an

abrasive wheel:

1. Hold the cut-off machine firmly with

both hands.

2. Maintain good balance and footing at

all times. Never cut while standing

on a ladder.

3. Do not exceed the maximum

operating speed marked on the

wheel.

4. Do not use a wheel that has been

dropped.

5. Never use circular saw blades,

carbide-tipped blades, rescue

blades, wood-abrasive blades or

toothed blades of any nature. Their

use increases the risk of injury from

reactive forces, blade contact and

thrown tips.

6. Do not cut any material for which the

abrasive wheel is not authorized.

7. Position the cut-off machine in such

a way that your body is clear of the

abrasive attachment.

8. Begin abrasive and continue at full

throttle.

9. Do not overreach.

 76

10. Do not cut above shoulder height.

11. Use your cut-off machine for abrasive

only. It is not designed for prying or

shoveling away any objects.

12. Do not grind on side of the abrasive

wheel.

13. Do not twist, thrust, knock or drop the

machine. This can cause damage

to the wheel.

14. Be especially alert for reactive forces

when abrasive with the front of the

wheel.

15. Be alert to shifting of the work piece

or anything that could cause the cut

to close and pinch the wheel.

16. Release the pressure on the

cut-off machine as you reach the

end of the cut. Too much pressure

may cause the operator to lose

control of the cut-off machine when

the abrasive wheel completes the

cut. The abrasive wheel may con-

tact the operator or strike some

foreign object and shatter.

17. Use extreme caution when

re-entering a cut and do not turn

the wheel at an angle or push the

wheel into the cut as this may result

in a pinching of the wheel.

Mounting the Arbor Bearing and Guard

The cutting blade drive (bearing with arbor and blade

guard) must be assembled before the machine is used for

the first time. The arbor bearing can be mounted to the

inboard or outboard side of the cast arm to suit cutting

requirements. Under normal circumstances the drive

should be mounted inboard of the arm because of the

better balance and only mounted outboard when required.

Inboard mounting

First fit V-belt (1) on the belt pulley (2) and position the

bearing plate (3) against the inside of the cast arm (4) so

that the tapped holes line up with the slots in the cast arm.

Position V-belt guard (5) against the outside of the arm

(4). Insert a hex. head screw (6) through one of the two

front holes and screw it into the bearing plate-move V-belt

guard to and fro to ease insertion. Now let go of the

bearing. Fit the other two screws (6) through the holes in

the V-belt guard (5) and screw them into the bearing plate

- the eccentric adjuster (7) must be fitted on the rear

screw.

Outboard mounting

Position the bearing plate (3) against the outside of the

arm (4) and fit the V-belt (1) on the belt pulley (2). If the

V-belt is new, this operation is easier if the M 10 hex. head

nut (8) is turned counterclockwise with the combination

wrench (17 mm), i.e. this turns the belt pulley (2). Position

bearing plate (3) so that the tapped holes line up with the

slots in the arm.

Tensioning the V-belt

Turning eccentric adjuster to tension V-belt

To tension the V-belt, first slacken off the two front hex.

head screws (6) and moderately tighten the rear one (with

eccentric adjuster). Then use a 13 mm open end wrench

to turn the eccentric adjuster (7) clockwise. This causes

the bearing to be shifted away from the engine and thus

tension the V-belt.

Once the correct tension has been reached, release the

eccentric adjuster (7) (as the rear hex. head screw has

been tightened down slightly the bearing and adjuster

remain in the set position). Then finally tighten down the

hex. head screws (6), starting with the rear one (with

eccentric adjuster).

The V-belt is correctly tensioned if it can be depressed

slightly (5-10 mm/ 3/16-3/8") with moderate thumb pressure.

Overtensioning of the V-belt will accelerate wear.

On a new machine, or if a new V-belt has been fitted, it is

advisable to check V-belt tension after about 1 operating

hour and correct it if necessary.

Fit the V-belt guard (5) on the inside of the arm. Insert a

hex. head screw (6) through one of the two front holes

and screw it into the bearing plate (3) - move V-belt guard

(5) to and fro to ease insertion. The assembly sequence is

otherwise as for "Inboard mounting".

When the cutting wheel is mounted outboard the wheel

guard does not have the full 360° adjustment since the

movement of the adjusting lever is restricted by the

handlebar mounting, i. e. reduced by about 20°.

TS 350 17

On the USA version a stop (1) is attached to the cut-off-

saw's bearing plate.

The rubber buffer (2) of this stop projects through the

flange of the abrasive wheel guard so that its adjustment

is limited to the range shown (see illustration). This

prevents the guard being turned too far.

It is necessary to take out the mounting screws (3) and

remove the rubber buffer (2) to turn the guard through

approx. 180° when the abrasive wheel is fitted on the out-

board side of the cast arm. Then turn the guard to the

required position and refit the rubber buffer on the stop.

Abrasive Wheels

Cutting wheels for free-hand cutting operations are sub-

jected to particularly high bending and compressive stres-

ses. STIHL has therefore developed - together with lead-

ing abrasive wheel manufacturers - top quality cutting

blades which exactly match the engine characteristics of

the cut-off-saw. They are of a consistently high quality

and perfectly balanced.

Out-of-round or poorly balanced abrasive wheels

increase vibration and reduce the service life of the

cut-off-saw. Good abrasive performance can only be

achieved with the abrasive wheels supplied by STIHL.

Abrasive wheels are heat sensitive. Always store your

cutoff-saw in a place where it is not exposed to direct

sunlight or other sources of heat.

Store spare cutting wheels in a dry place where there is

no risk of frost, preferably at a constant temperature.

Your STIHL dealer stocks a range of special abrasive

wheels (3 and 6 mm / 0.12 and 0.24 in thick) for the mani-

fold applications cut-off-saw. For example, wheels for

abrasive bituminous material, gravel asphalt, stone, con-

crete, clay pipe, structural steel, highly alloyed steel, cast

iron, non-ferrous metals etc.

Mounting the abrasive Wheel

The engine must be switched off and the arbor blocked

before mounting or removing the abrasive wheel. To do

this, push the locking pin squarely through the hole in the

V-belt guard. If one of the V-belt pulley spokes is in the

way, use the combination wrench to turn the arbor until the

locking pin can be inserted.

Slacken off and remove the M 10 hex. head screw with the

combination wrench (17 mm) and take it off the arbor

together with the front thrust washer.

The cutting wheel can now be pulled off the arbor and

taken out of the guard. This operation is made easier if the

blade guard is turned so that its lower edge is vertical.

Before fitting the new abrasive wheel, check that the rear

thrust washer is positioned so that the notch in its center

hole engages over the lug on the arbor.

Mount the new abrasive wheel in the reverse sequence to

that described above. Make sure that the locking tab on

the front thrust washer engages in one of the two slots in

the arbor. Use combination wrench to securely tighten the

M 10 hex. head screw.

Pay attention to arrows for direction of rotation when fitting

a diamond abrasive wheel.

If a wider kerf is required (e. g. for installing induction

loops in road surfaces), two diamond abrasive wheels

can be used side by side. In such a case it is essential to

ensure that the segments of both wheels are positioned

exactly next to one another.

Important! Two composite wheels must never be used

simultaneously, for they may break and cause injuries

as they wear down unevenly.

This engine is certified to operate on

unleaded gasoline and with the

mix ratio 50:1.

Your two-stroke engine requires a

mixture of brand-name gasoline and

quality two-stroke engine oil with the clas-

sification TC.

Use regular branded unleaded gasoline

with a minimum octane rating of

90 RON (U.S.A./Canada: pump octane

min. 89!). If the octane number of the

regular grade gasoline in your area is

lower use premium unleaded fuel.

Fuel with a lower octane rating may

result in preignition (causing "pinging")

which is accompanied by an increase in

engine temperature. This, in turn,

increases the risk of the piston seizure

and damage to the engine.

The chemical composition of the fuel is

also important. Some fuel additives not

only detrimentally affect elastomers

(carburetor diaphragms, oil seals, fuel

lines etc.), but magnesium castings as

well. This could cause running problems

or even damage the engine. For this

reason it is essential that you use only

name branded fuels!

Use only STIHL two-stroke engine oil or

equivalent branded two-stroke air-

cooled engine oils with the classification

TC for mixing.

We recommend STIHL 50:1 two-stroke

engine oil since it is specially formulated

for use in STIHL engines.

Do not use BIA or TCW (two-stroke

water cooled) mix oils!

Take care when handling gasoline.

Avoid direct contact with the skin and

avoid inhaling fuel vapour.

The canister should be kept tightly

closed in order to avoid any moisture

getting into the mixture.

The fuel tank and the canister in which

fuel mix is stored should be cleaned

from time to time.

Center: Stop switch away from "Stop"

Bottom: Starting-throttle position

Startin

g

To start, place cut-off-saw on ground, make sure you

have a firm foothold and the cutting blade is clear of all

obstructions. Nobody else should be standing within the

working range of the machine.

Starting procedure

1. If the engine is cold, move choke lever (1) to "Choke".

If the engine is warm, move choke lever (1) away from

"Choke". This procedure also applies when the engine

has been running but is still cold.

2. Move stop switch (2) away from "STOP".

3. Set throttle trigger (3) to half-throttle position by

pressing in throttle trigger interlock (4), throttle trigger

(3) and starting-throttle lock (5) in that order. Let go of

throttle trigger (3) first and then the starting-throttle-lock

(5).

4. Now hold the saw firmly on the ground with your left

hand on the handlebar (6).

5. Pull starter grip (5) slowly with your right hand until you

feel the starter engage. Then give starter rope a brisk,

strong pull, but do not pull it out more than approx.

70 cm (27.5 in) as it might otherwise break.

Continue cranking until engine begins to fire. Then, if

you are starting from cold, move choke lever (1)

immediately away from "Choke" (choke opens) and pull

again.

6. As soon as the engine is running, disengage starting

throttle lock (5) immediately by briefly squeezing the

throttle trigger so that the engine can settle down to

idle speed.

7. The engine is stopped by moving the stop switch (2) to

the "STOP" position.

TS 350 21

Top: Starting

Center: Throttle trigger in idle position

Bottom: Stop switch in "STOP" position

Points to observe when starting:

The choke lever is mechanically connected to the

carburetor's choke valve. The choke valve is closed when

the choke lever is on "Choke" and open when the choke

lever is moved away from "Choke".

When starting a cold engine only keep the choke lever in

the "Choke" position until the engine begins to fire. Then

move the choke lever immediately, away from "Choke",

even if the engine stops and you have to repeat the

starting procedure. If you leave the choke lever on

"Choke", the combustion chamber will flood and stall the

engine.

If you have moved the choke lever away from "Choke"

after the engine fired and the engine still does not run after

several attempts, it is already flooded. In such a case,

remove and dry off the spark plug. Clear the combustion

chamber by pulling starter rope several times with the

spark plug still removed and the stop switch in the "STOP"

position. When you now try to start, move the choke lever

away from "Choke", even if the engine is cold, and set the

throttle trigger to the starting-throttle position.

In very cold weather only open the choke sligtly after

starting-move choke lever to center position. Allow engine

to warm up for a brief period at half-throttle. Then move

choke lever away from "Choke" and disengage the

starting throttle lock.

A new engine or one which has been run until the fuel

tank is dry will not start first time after fueling because fuel

only begins to reach the carburetor when the engine has

been turned over few times on the starter.

A factory new machine should be run

with the carburetor set slightly on the

rich side for the first three tank fillings

(see chapter on "Carburetor") so that the

cylinder bore and the bearings receive

additional lubrication during the break-in

period.

As all the moving parts have to bed in

during the break-in period, the frictional

resistances in the engine are greater

during this period. For this reason the

engine only develops its maximum

power after about 5 to 15 tank fillings.

The carburetor setting must never be

made leaner in order to achieve an

apparent increase in power as this could

cause the engine to exceed its maximum

permissible rpm (see "Specifications"

and "Carburetor").

'XULQJRSHUDWLRQ

After a long period of working at full load

it is advisable not to shut off the engine

immediately, but let run for a short while

at idling speed. This allows the heat

which has been generated in the engine

during full throttle operation to be

dissipated by the flow of cooling air and

also protects engine-mounted

components (ignition, carburetor) from

thermal overload.

Place silencer and filter cover on the studs, fit wingnuts

Air Filte

r

The air filter's function is to intercept dust and dirt in the

combustion air and thus reduce wear on engine

components.

Clogged air filters reduce engine power, increase fuel

consumption and make starting more difficult.

The filter system consists of a prefilter, main filter and

auxiliary filter. Always clean the prefilter first if engine

power begins to drop off. It should be knocked out on the

palm of your hand or blown out with compressed air. The

prefilter can also be washed out in clean gasoline if it is

very dirty, but must be completely dry before you refit it.

For this reason we recommend that you use two prefilters

in rotation.

Always renew a dirty main filter. We do not recommend

cleaning this paper element since the results are

unsatisfactory and the risk of damaging the filter paper is

too great.

If the main filter should fail for any reason (e.g. damage),

the auxiliary filter will protect the engine from damage.

Failure of the main filter is indicated by a noticeable layer

of dirt on the flocked wire mesh of the auxiliary filter. If this

happens, clean the auxiliary filter when you change the

main filter.

As long as the main filter is in good condition there is no

need to clean the auxiliary filter as it is normally kept free

from dirt.

Close the choke shutter - move choke lever to "Choke".

Unscrew the wingnuts (1) and take off the filter cover (2)

and silencer (3). Pull the prefilter (4) off the main filter (5).

If necessary, also remove the auxiliary filter (6), knock it

rope until it is fully rewound on the rope rotor by spring

force.

The rewind spring is tensioned correctly if the starter grip

is held firmly in place against the starter housing by spring

tension and does not droop. If more tension is required

add one more turn on the rope rotor. The rope rotor should

be able to be rotated by at least one-half an extra turn with

the rope pulled all the way out. If spring tension is too

great pull out the starter rope, hold the rotor firmly by

hand, and remove one turn of the rope.

A rewind spring that is tensioned too heavily will

probably break.

Re-install the fan shroud with the three retaining screws

securely tightened.

Changing the V-belt

Arbor bearing and guard mounting screws

To change the V-belt, first remove the arbor bearing and

abrasive wheel guard. To do this, unscrew the three

mounting screws, take off the V-belt guard and lift the

arbor bearing and abrasive-blade guard away from the V-

belt.

Now remove the three mounting screws from the cast

arm. Push the engine slightly to one side and take off the

cast arm.

Place the new V-belt in the cast arm (see illustration) and

reassemble. Check the position and freedom of move-

ment of the V-belt before finally tightening the mounting

screws. Refit the arbor bearing and abrasive wheel guard

- refer to "Assembling the Arbor Bearing and Guard" and

"Tensioning the V-belt".

and workmanship which cause it to fail

to conform with U.S. EPA standards for

the first two years of engine use from the

date of sale to the ultimate purchaser.

STIHL Incorporated must warrant the

emission control system on your small

off-road engine for the period of time

listed below provided there has been no

abuse, neglect or improper maintenance

of your small off-road equipment engine.

Your emission control system includes

parts such as the carburetor and the

hoses, and connectors and other

emission related assemblies.

Where a warrantable condition exists,

STIHL Incorporated will repair your small

off-road equipment engine at no cost to

67,+/,QFRUSRUDWHG)HGHUDO(PLVVLRQ&RQWURO:DUUDQW\6WDWHPHQW

performance of the required mainte-

nance listed in your owner’s manual.

STIHL Incorporated recommends that

performance of all scheduled mainte-

nance.

Any replacement part or service that is

equivalent in performance and durability

may be used in non-warranty mainte-

nance or repairs, and shall not reduce

the warranty obligations of the engine

manufacturer.

As the small off-road equipment engine

owner, you should be aware, however,

that STIHL Incorporated may deny you

warranty coverage if your small off-road

equipment engine or a part has failed

due to abuse, neglect, improper mainte-

nance or unapproved modifications.

warranted part which is scheduled for

replacement as required maintenance

will be warranted for the period of time

up to the first scheduled replacement
