Kickback

Kickback may occur when the guide bar nose or

tip comes into contact with a foreign object, or

whenthe“sawkerf”(gapinthewoodbeingcut)

closes in on the bar and pinches the saw chain.

Tip contact in some cases may cause a lightning-

fast reverse action, kicking the guide bar up and

back toward the operator.

Pinching the saw chain along the top of the

guide bar may push the guide bar and the saw

unit backward toward the operator.

Either of these reactions may cause the operator

to lose control of the chainsaw, which could

result in serious personal injury or death.

Do not rely exclusively on the safety devises

built into your saw. As a chainsaw user, it is

your responsibility to understand the inherent

dangers of chainsaw use and the precautions

necessary to minimize those dangers.

Precautions to Avoid Kickback:

•Alwaysgripthe chainsaw rmlywithboth

hands; the right hand on the rear handle, and

the left hand on the forward grip.

• Makecertaintheareainwhichyouarecutting

is free from obstructions. Do not let the guide

bar nose come into contact with a log, branch, rock or other

objects while cutting. Such contact could result in a kickback.

• Alwaysmakecutsathighenginespeeds.

• Donotover-reachorcutaboveshoulderheight.

• Alwaysmaintainasharp and cleansawchain. Follow

manufacturer’s sharpening and maintenance instructions for

the saw chain.

• Only usereplacementbarsand chains specifiedbythe

manufacturer or an appropriate equivalent.

Sawing

•Thissawisprovidedforthesoleintendedpurposeofcutting

wood. Do not cut other materials with this saw.

• Donotattachothertoolsoraccessoriestotheoutputshaftof

the power unit. Doing so will void the manufacturer’s warranty.

• Donotapplyexcessivepressuretoforcethesawthroughthe

cut. Run the engine at full throttle and apply only light pressure.

• Alwaysmaintainarmfooting.

• Nevercutfromastepladderorwhileinatree.

• Neverusetheguidebarasameanstolift,pry,moveorsplit

race the engine or pull the saw out of the cut by force. Use a

wedge or lever to open the cut and pull the saw free.

Felling a Tree

Felling refers to the process of cutting down a standing tree.

Numerous factors must be taken into consideration when

felling a tree. First consider the environmental factors which will

determine the felling direction:

• Windisamajordeterminingfactoroffellingdirection.

• Locationandnumberofheavybranchesandtheleanofthetree.

• Easeofbuckingandclean-upafterfelling

• Nearbystandingtimberinwhichthefelledtreecouldhangup.

• Locationofpower, telephoneanddatautilities,buildings,

roads, bodies of water, property lines, etc.

• Woodstructureandcondition(i.e.rottenheartwoodorcore).

• Keepallbystandersatleast2-1/2treelengthsawayfromthe

base of the tree to be cut. This area is considered a danger zone

and must be avoided before and during the felling operation.

Retreat Path

Plan two (2) retreat paths away from the felling direction of the

tree. Do not retreat in the opposite direction from the falling tree.

Instead, retreat at a 45-degree angle to either side.

• Cleartheretreatpathsofallobstacles.

• Placeallexcesstoolsandequipmentasafedistancefromthe

Felling Notch

The felling notch is the rst cut when felling a

tree. The notch will act as a hinge and will direct

the tree to fall in the desired direction.

1) Begin the felling notch by lining up the guide bar perpendicular

to the desired felling direction.

2) Make a downward cut at 45-degress to a depth of about 1/5

to 1/4 of the overall diameter of the tree.

3) Finish the notch by making a horizontal cut perpendicular to

the desired felling direction.

4) Remove the resultant piece.

Felling Cut

Alert others in the area of imminent danger of the falling tree. Double

check that no one has entered the area in the felling direction.

1) Begin the felling cut by making a horizontal cut perpendicular

to the intended felling direction and approximately 1-2 inches

above the bottom of the felling notch.

2) Leave approximately 1/10 of the tree’s diameter uncut. This

will form the hinge.

3) Drive plastic or wooden wedges into the felling cut to control

the fall.

4) As the tree begins to fall, alert others and immediately

evacuate the area around the tree.

Limbing a Felled Tree

“Limbing”referstoremovingthelimbsfromafallentree.Thereisan

extremely high danger of kickback during the limbing operation. Do

not work with the nose of the guide bar, as this could cause a kickback.

Use extreme caution and avoid contact between the nose of the bar

and the log or other limbs. Do not stand on the log while limbing it as

the log may roll as limbs are removed and the center of gravity shifts.

Start limbing by removing limbs from the top side of the log,

leaving limbs on the bottom to support the log up o the ground.

Limbs under tension may pinch the guide bar and saw chain.

Shut o the engine and lift the limb to remove the bar safely.

WARNING

INEXPERIENCED USERS SHOULD NEVER ATTEMPT TO

CUT TREES WITH ROTTEN HEARTWOOD THE CORE OF

THE TREE. THERE IS AN INCREASED RISK THAT THE TREE

COULD SNAP OR SPLIT UNEXPECTEDLY DURING THE CUT.

ALSO CHECK FOR DEAD OR ROTTEN LIMBS PRIOR TO

BEGINNING THE CUT. DEAD LIMBS CAN VIBRATE LOOSE

FROM THE TREE AND FALL, STRIKING THE OPERATOR.

CAUTION

ONLY TRAINED AND EXPERIENCED PROFESSIONALS

SHOULD FELL TREES NEAR OVERHEAD LINES AND

BUILDINGS. A SLIGHT MISJUDGMENT OF WIND

DIRECTION OR NATURAL LEAN OF A TREE COULD

RESULT IN MAJOR PROPERTY DAMAGE.

CAUTION

DO NOT CUT THROUGH THE HINGE. CUTTING

THROUGH THE HINGE INCREASES THE RISK OF

LOSING CONTROL OF THE FELLING DIRECTION.

CAUTION

LOGS AND LIMBS UNDER TENSION CAN SPRING BACK

WHEN CUT LOOSE. THIS LIGHTNING FAST ACTION

COULD CAUSE A LOSS OF CONTROL OF THE CHAINSAW.

Bucking a Log

“Bucking”isthecross-cutoperationofcuttingalogintousable

sections. Do not stand on the log while bucking as it may roll.

When bucking on a slope, stand uphill of the log in case it begins

to roll unexpectedly. Cut only one log at a time.

• Whenbuckingsmalllogs,placethemina“V”shapedbucking

horse to keep them at a working level. Never allow a bystander

to hold the log. Never hold the log with your leg or foot.

• Tobuckalogonatground,makeperpendicularcutsthrough

about half of the diameter of the log. Roll the log and nish

the cuts from the other side.

• Tobuckapillowedorsupportedlog,alwaysmakearelievingcut

through about 1/3 the diameter of the log from the compressed

side. Finish with a bucking cut from the tension side of the log.

Tip: When cutting firewood, make sure you know the

optimum length of the nished rewood ahead of time. Use

the guide bar as an approximate length gauge.

Pruning

Pruning is removing limbs from a standing tree, often for

purposes of maintaining a tree’s health or aesthetics. Always

work with a rm footing. Never cut from a stepladder. Do not

over reach. Do not cut above shoulder height.

1) Begin pruning by making a relief cut about 3 inches away from the

trunk of the tree to a depth of about 1/3 the diameter of the branch.

2) Complete the cut from above, just inside of the initial relief cut.

3) Finish pruning by making a smooth even cut nearly ush to the

trunk. It is recommended to only prune trees while they are dormant

in the fall and winter to reduce the risk posed by disease or insects.

ENGINE SAFETY PRECAUTIONS

Warning Carbon Monoxide Poisoning

Engines give off carbon monoxide, an odorless, colorless,

poisonous gas. Carbon monoxide may be present even if you do

not smell or see any engine exhaust. Breathing carbon monoxide

can cause nausea, fainting or death, in addition to drowsiness,

dizziness and confusion. If you experience any of these

symptoms, seek fresh air and medical attention immediately.

If your product comes with a separate engine manual, be

sure to read and follow all safety and warning precautions

outlined there, in addition to any in this manual.

Preventing Carbon Monoxide Poisoning

• Always start and run engine outdoors. Do not start or run

engine in an enclosed area, even if doors or windows are open.

• Never try to ventilate engine exhaust indoors. Carbon

monoxide can reach dangerous levels very quickly.

• Never run engine outdoors where exhaust fumes may be

pulled into a building.

• Never run engine outdoors in a poorly ventilated area where

the exhaust fumes may be trapped and not easily taken

away. (Examples include: in a large hole or areas where hills

surround your working area.)

• Never run engine in an enclosed or partially enclosed area.

(Examples include: buildings that are enclosed on one or

more sides, under tents, car ports or basements.)

• Always run the engine with the exhaust and muer pointed

in the direction away from the operator.

• Never point the exhaust muer towards anyone. People

should always be many feet away from the operation of the

engine and its attachments.

• Do not change the engine governor settings or over-speed

the engine.

WARNING

ENGINES GIVE OFF CARBON MONOXIDE, AN ODOR

LESS, COLORLESS, POISONOUS GAS. CARBON MON

OXIDE MAY BE PRESENT EVEN IF YOU DO NOT SMELL

OR SEE ANY ENGINE EXHAUST. BREATHING CAR

BON MONOXIDE CAN CAUSE NAUSEA, FAINTING OR

DEATH, IN ADDITION TO DROWSINESS, DIZZINESS

AND CONFUSION.

IF YOU EXPERIENCE ANY OF THESE SYMPTOMS, SEEK

FRESH AIR AND MEDICAL ATTENTION IMMEDIATELY.

Gasoline Fires and Handling Fuel Safely

Use extra care in handling gasoline and other fuels. They are

ammable and vapors are explosive.

• When storing extra fuel be sure that it is in an appropriate

container and away from any re hazards.

• Prevent re and explosion caused by static electric discharge.

Use only nonmetal, portable fuel containers approved by the

Underwriter’s Laboratory (U.L.) or the American Society for

Testing & Materials (ASTM).

• Always ll fuel tank outside in a well ventilated area. Never ll

your fuel tank with fuel indoors. (Examples include: basement,

garage, barn, shed, house, porch, etc.) Never ll tank near

appliances with pilot lights, heaters, or other ignition sources.

• If the fuel has to be drained, this should be done outdoors.

The drained fuel should be stored in a container specically

designed for fuel storage or it should be disposed of carefully.

• Never remove the fuel cap or add fuel with the engine

running. Stop engine and allow to cool before lling.

• Do not smoke.

• Never drain fuel from engine in an enclosed area.

• Always wipe up excess (spilled) fuel from engine before

starting. Clean up spilled fuel immediately. If fuel is spilled,

do not start the engine but move product and fuel container

from area. Clean up spilled fuel and allow to evaporate and

dry after wiping and before starting.

• Allow fuel fumes/vapors to escape from the area before

starting engine.

• Test the fuel cap for proper installation before starting and

using engine.

• Always run the engine with fuel cap properly installed on

the engine.

• Never smoke while relling engine fuel tank.

• Do not store engine with fuel in fuel tank indoors. Fuel and

fuel vapors are highly explosive.

• Always have an adult fill the fuel tank and never allow

children to ll the engine.

• Never allow an adult or anyone under the inuence of drugs

or alcohol to ll engine.

• When storing gasoline or equipment with fuel in the tank,

store away from furnaces, stoves, water heaters or other

appliances that have a pilot light or other ignition source

because they can ignite gasoline vapors.

BURNS AND FIRES

The muer, muer guard and other parts of the engine be-

come extremely hot during the operation of the engine. These

parts remain extremely hot after the engine has stopped.

Prevention of Burns and Fires

• Neverremovethemuerguardfromtheengine.

• Nevertouchthemuerguardbecauseitisextremelyhot

and will cause severe burns.

SAFETY FEATURES

This saw is equipped with certain safety features and devices

to protect the user from harm in the event the saw reacts

unexpectedly to external forces:

1. Chain Brake: The saw is equipped with a chain brake designed

to stop the chain instantaneously upon activation. The chain

brake can be activated in one of two ways:

• The forward hand guard doubles as an activation lever for

the hand brake. It can be activated manually, or it may be

activated by the user’s arm if a kickback occurs.

• Thesawisalsoequippedwithan“InertialChainBreak.”The

same mechanism as above is activated by the inertial force

created when a counterweight under the forward hand

guard accelerates toward the bar nose during a kickback.

• Proper cleaning and care of the chain brake system are

required to ensure reliable operation in the eld. You should

also check your chain brake for proper operation regularly.

To check your chain brake:

Manually activate the chain brake by pushing the forward

hand guard toward the bar nose. There will be an audible

click when the chain brake engages. If there is no audible

click, the brake may already be engaged. Pull back on the

forward hand guard to deactivate the brake. An audible

click should be heard when the brake disengages. If there

is still no audible click, the brake is not functioning properly.

Remove the clutch cover, clean and reassemble, and re-test.

If no audible click is heard, contact customer service for

further assistance.

With the saw’s engine shut o and the brake disengaged,

firmly grasp both handles and hold the saw over a log

or low stump. Swing the bar nose sharply down until it

makes contact. This should create enough inertial force

to automatically activate the chain brake. When the brake

engages, an audible click should be heard. If no audible click

is heard, the brake is not functioning properly. Remove the

clutch cover, clean and reassemble, and re-test. If no audible

click is heard, contact customer service for further assistance.

2. Throttle Interlock: This saw is equipped with a throttle

interlock designed to prevent accidental engagement of

the throttle control. The throttle interlock is disengaged by

depressing the red tab on top of the rear handle. This is usually

accomplished when the user grasps the rear handle to operate

the saw.

3. Chain Catcher: Each saw is equipped with a chain catcher

beneath the clutch cover. If the chain is ever thrown from the

guide bar, or if the chain breaks, the chain catcher is designed

to capture the chain and prevent it from whipping back toward

the operator.

NOTE: Inspect the chain catcher before each use. Replace if

missing or badly damaged.

4. Kickback Reduction Guide Bar and Saw Chain: This saw has

been equipped with a Double Guard® 91 guide bar and 91VG

S-Series Low Kickback saw chain by Oregon®. The features of

this bar and chain combination are design to reduce the risk

of kickback. To maintain adequate kickback prevention, only

use these components when replacing guide bar or saw chain.

ASSEMBLY

The Earthquake Chainsaw carton includes the following

- Power Unit: Pre-assembled engine, handles, fuel tank,

oil tank, and chain brake handle.

- GuideBar:OregonDoubleGuard14”or16”,depending

on the saw model.

- SawChain:Oregon91Por 91VGS52(14” models) or

- “Scwrench”Multi-tool:Combinationplug/barwrench

and screwdriver

- Bar Scabbard: Plastic guard that ts over the guide bar

and saw chain.

ASSEMBLING YOUR CHAINSAW

1. Carefully remove all items from the packaging. Place the

power unit on a at, stable work surface with the muer

facing to your right.

2. Pull back (toward the forward handle) on the brake lever to

ensure that the chain brake is disengaged.

3. Usingthe“Scwrench”multi-tool,loosenandremovethebar

nuts securing the clutch cover to the power unit. Set the clutch

cover aside. Tip: If working in the eld, place the bar nuts in

the clutch cover to keep from losing them in grass or foliage.

4. Remove the plastic shipping spacer from the bar studs. The

purpose of this spacer is to keep the clutch cover in the correct

position when the guide bar is not installed on the power unit.

SEE FIGURE 1.

5. Install the guide bar on the bar studs, and slide the bar back

until it comes into contact with the drive sprocket.

6. Carefully remove the saw chain from its package. Stretch the

chain out into a long horizontal loop. The cutting teeth on

the top length of chain should face away from the power

unit. The cutting teeth on the bottom length of the chain

should face toward the power unit. Protective gloves should

be used when handling the chain.

7. Wrap the chain around the drive sprocket rst, and lay the

drive links of the chain into the groove along the outer

perimeter of the guide bar. Lay the chain over the nose (tip)

of the guide bar.

8. Slide the bar forward until the bar mates with the tensioning

tab. Make sure that the drive links of the chain are seated

within the groove around the perimeter of the bar. If the bar

will not slide forward far enough, use the screwdriver end of

the Scwrench to turn the tension screw counter-clockwise.

The tension screw is located on the front of the power unit,

next to the guide bar.

9. Replace the clutch cover over the bar, and turn the bar nuts

onto the bar studs. Only nger tighten the bar nuts at this step.

10. Locate the tension screw on the front of the power unit next

to the guide bar. Use the Scwrench to turn the tension screw

clockwise. This will take the slack out of the saw chain. When

properly tensioned, two conditions must be met:

•Thechainshouldnothangordroopawayfromtheguide

bar.

•Youshouldbeabletopullthechainslightlyawayfrom

the guide bar, but not so far as to be able to disengage the

drive links from the groove around the perimeter of the bar.

11. Pull up on the guide bar’s nose and use the Scwrench to tighten

the bar nuts. Check that the chain spins freely around the bar

by hand. If there is resistance, the chain may be too tight.

12. Place the bar scabbard over the guide bar and saw chain. This

guard will help to protect the user from the sharp cutting

teeth as well as help keep the cutting teeth sharp when the

saw is not in use.

13. Check the tension of the saw chain frequently during use,

especially during the rst two hours of use on a new chain.

Re-tension as needed.

14. Always release the tension in the chain after nishing work

and before the saw chain and guide bar cool completely. As

the saw chain heats up during operation, it will expand and

stretch, requiring re-tensioning on occasion. As the saw cools

down the saw chain will shrink, and if left tensioned, could

cause severe and permanent damage to the guide bar or the

power unit’s drive components.

WARNING

FAILURE TO PROPERLY TENSION THE CHAIN COULD

RESULT IN DAMAGE TO THE UNIT OR SEVERE INJURY

OR DEATH. OVER TENSIONING COULD CAUSE DAMAGE

TO THE SAW’S POWER UNIT OR GUIDE BAR. LACK OF

TENSION COULD CAUSE THE CHAIN TO DISENGAGE

THE BAR COMPLETELY, ALLOWING IT TO WHIP BACK

WHERE IT COULD CONTACT THE OPERATOR CAUSING

SEVERE INJURY OR DEATH.

FILLING THE BAR AND CHAIN OIL RESERVOIR

1. While the engine is cool for re-fueling, clean debris from area

around the bar and chain oil cap.

2. Loosen oil cap slowly.

3. Carefully add bar and chain oil without spilling.

4. Do not ll oil reservoir completely full; allow space for oil to

expand.

5. Replace cap and tighten. Wipe o any spilled oil before starting

engine.

Note: Do not use waste or recycled oil. Waste or recycled oil

could contain contaminants which will cause damage to the

oil pump.

WARNING

CHAIN BRAKE WILL NOT PREVENT A KICKBACK. IN THE

EVENT OF A KICKBACK, THE CHAIN BRAKE IS DESIGNED

TO REDUCE THE RISK OF INJURY TO THE OPERATOR.

WARNING

DO NOT MODIFY OR ALTER THE FUNCTIONALITY OF

THE THROTTLE INTERLOCK IN ANY WAY. DOING SO

WILL ALLOW ACCIDENTAL ENGAGEMENT OF THE

THROTTLE WHICH WILL RESULT AN UNEXPECTED

OPERATION OF THE SAW CHAIN.

WARNING

CHAIN CATCHER IS INTENDED TO PREVENT INJURY

IN THE EVENT OF A CHAIN MALFUNCTION. NEVER

OPERATE A SAW WITHOUT A CHAIN CATCHER.

REPLACE IF MISSING OR BADLY DAMAGED.

OPERATION

FILLING FUEL TANK

1. Shut o engine and allow engine to completely cool before

relling the fuel tank.

2. Move to a well-ventilated area, outdoors, away from ames

and sparks.

3. Clean debris from area around the fuel cap.

4. Loosen fuel cap slowly.

5. Carefully add fuel without spilling.

6. Do not ll gas tank completely full; allow space for fuel to

expand.

7. Immediately replace fuel cap and tighten. Wipe o spilled

fuel and allow to dry before starting engine.

The saw chain needs to stay lubricated during operation of

the unit. Aside from the fuel reservoir on the chainsaw, there

is also a bar and chain oil reservoir. Use only oil that has been

designed specically for use with chainsaws. Bar and chain oil

has chemical properties which allow it to adhere to the saw

chain and provide better lubrication while the chain is in motion.

The saw is equipped with an adjustable automatic oiler. The

oiler and oil reservoir are designed such that a full tank of fuel

will run out before a full tank of oil. This ensures that the bar

and chain will receive a constant ow of oil during operation.

Always top o your oil reservoir when re-fueling.

BAR AND CHAIN OIL

The saw is equipped with an adjustable chain oiler. The oil

pump, driven by the drive sprocket, will only pump oil when the

engine is running at high enough speeds to engage the clutch

and rotate the chain. Furthermore, the ow of oil is adjustable to

accommodate variations in chain oil due to temperature.

To adjust the oil pump, insert a screwdriver in the small notch

beneath the clutch and drive sprocket. To increase the ow

of oil, turn the screwdriver counter-clockwise. To decrease

the ow of oil, turn the screwdriver clockwise. For optimum

performance, use a higher rate of ow with thicker oil or in

colder temperatures, and a lower rate of ow with thinner oil or

in warmer temperatures.

The guide bar and saw chain need to be well lubricated during

operation to prevent permanent damage from friction and heat.

Be sure to check the oil supply to the bar and chain before use.

1. After starting the engine, hold the saw up with the chain

suspended in front of or above a test surface.

2. Run the engine at about half throttle.

3. Oil should be ung o of the rotating chain onto the test

surface.

If the saw chain seems dry, but there is some oil present on the

bar or test surface, the oil pump may be set too low. Increase

the setting by turning the adjustment screw counter-clockwise.

If the saw chain and guide bar are dry and there is no oil on the

test surface, the oiler port and guide bar may need cleaning.

Remove the clutch cover, bar, and chain, and clean under the

clutch cover with a brush and clean the guide bar with a wire or

small screwdriver.

Reassemble and retest for oil presence. If no oil is present after

adjusting the oiler setting and cleaning the oiler port, the oil

pump may not be functioning. Discontinue use of the unit and

contact your local authorized service center or customer service

for assistance.

In compliance with EPA regulations, any adjustments to the

carburetor must be made by an authorized service center.

An authorized service center is capable of troubleshooting

carburetor problems, adjusting carburetors to perform correctly,

and adjusting carburetors to compensate for altitude.

IMPORTANT NOTE: Carburetor is set at factory. Further

adjustment must be performed by an authorized service center.

Contact customer service for a list of authorized service centers.

ENGINE MAINTENANCE

COOLING FINS

Cooling ns, air inlets, and linkages must be free from any debris

before each use.

AIR FILTER

Never run engine without air cleaner properly installed. Added wear

and engine failure may occur if air cleaner is not installed on engine.

Service air cleaner every 3 months or after 20 hours of operation.

Clean lter daily in extremely dusty conditions.

Steps for Cleaning Air Filter

1. Remove the air cleaner cover by turning the thumb screw on top

of the power unit counter-clockwise and lifting the cover o.

2. To remove the lter, lift the lter element o of the threaded stud.

3. Larger surface dust and dirt particles can be removed from the lter

element by lightly tapping a corner of the lter against a hard surface.

4. To clean ner dust trapped in the mesh screens, split the lter

by inserting a at screwdriver between the dogs on one corner

of the lter element and twisting.

5. Using an air compressor at a low pressure or a store-bought

compressed air duster, blow air through the mesh from the inside.

6. Press the two lter halves back together by squeezing around the

rim. Do not place pressure on the mesh or a puncture could occur.

7. Place the lter back over the threaded rod, making sure to seat

the lter on the O-ring on the carburetor.

8. Place the air cleaner cover back on the saw body and turn the

thumb screw clockwise until nger tight.

SPARK PLUG

The recommended spark plug is a NGK BPM6A, Champion CJ7Y,

or Torch L7TC.

Steps for Removing the Spark Plug

1. Remove the air cleaner cover by turning the thumb screw on top

of the power unit counter-clockwise and lifting the cover o.

2. Disconnect the spark plug cap and clean any debris from

around the spark plug area.

3.Removesparkplugusingthe“Scwrench”multi-tool.Replaceif

SAW CHAIN TENSION MAINTENANCE

Keeping the saw chain at the proper tension is necessary for

safe operation and will help prolong the life of the saw chain

and the guide bar.

1. Shut the power unit o and allow the saw to cool.

2. The saw chain should not hang down from the bottom edge

of the guide bar.

3. Wearing protective gloves, hold the guide bar with one hand

and pinch the chain with the free hand.

4. Pull down on the chain. It should pull away from the bar, but

the drive links should not disengage the groove around the

perimeter of the guide bar.

5. Add or remove tension as needed.

6. Hold up on the guide bar nose and tighten the bar nuts with

the Scwrench.

Add tension at the beginning of every work session.

Check tension at every re-fueling.

Remove tension at the end of every work session.

SAW CHAIN MAINTENANCE

Keeping the saw chain sharp is a critical component to operating

a chainsaw. A dull saw chain will drastically reduce cutting

eciency and can pose certain safety hazards.

• Avoidunintentionallystrikingforeignobjects.Thiscancause

a kickback, but will also reduce the sharpness or permanently

damage the saw chain.

• Avoidcuttingwoodthathasbeendrugontheground.Sand,

dirt, and mud stuck to the log will dull the saw chain.

• Avoidcutting woodthatmaycontainmetalsuchasnails,

staples, or wire.

• Avoidcuttingallthewaythroughwhenbuckingalog.This

could allow the chain to come into contact with the soil below,

dulling the saw chain.

Sharpening Saw Chain Cutters (Teeth)

The saw chain included with this saw is a 91VG Chamfer Chisel™ or

91P Chamfer Chisel™ and requires a 5/32 inch round le (included

in the original packaging).

When to have your saw chain sharpened:

• Sawdustbecomespowder-like

• Youneedtoforcethesawintothecut

• Thesawtendstocutthroughatanangleinsteadofmakinga

straight cut

• Vibrationincreases

• Fuelconsumptionincreases

Always inspect your saw chain prior to sharpening. Check for

the following:

• Bentorburreddrivelinks

• Brokencuttersortie-straps

• Looserivetsorbrokenrivetheads

If broken components are found, discard the chain immediately.

To properly sharpen you saw chain:

1. Be sure to have the correct size le and le guide.

2. When hand ling it’s important that 1/5, or 20 percent, of the

le’s diameter is always held above the cutter’s top plate.

3. Keep the correct top-plate ling angle line on your le guide

parallel with the chain.

4. Sharpen all cutters on one side of the chain rst. Sharpen

by ling from the inside of each cutter to the outside. After

sharpening the rst side, turn the saw around and repeat the

process for cutters on the other side of the chain.

5. If the chrome surface of the top or side plates is damaged, le

back until such damage is removed.

6. Keep all cutters at an equal length. Begin ling on the cutter

with the most damage, and le all subsequent cutters to the

same length.

7. DO NOT alter or le the tops of bumper tie strap links (between

each cutter) on the 91VG chain.

8. FileONLYonthe“Push”stroke,donotpulltheleagainstany

metal object as this will damage the le.

It is also important to maintain the depth gauge setting

throughout the lifespan of the saw chain. 91VG and 91P chains

useadepthsettingof.025”.Thissettingshouldbecheckedand

corrected every third or fourth time the saw chain is sharpened.

1. Place the correct depth-gauge tool over the chain, with one

depth gauge protruding through the slot in the tool.

2. If the depth gauge extends above the slot, use a at le to bring

the depth gauge ush with the top of the tool. Use only the

push stroke of the le. Pulling the le will damage the le.

3. Make sure to round over the leading edge of the depth

gauge to prevent kickbacks and tie strap breakage.

STORAGE

When storing the chainsaw for periods of three months or

longer:

1. Empty and clean the fuel tank in a well-ventilated area.

2. Dispose of fuel properly. Local regulations may apply. Contact

your local government or hazardous material service for

instructions.

3. Run the engine until the carburetor is dry. This will draw the

• Any warranted part that is not scheduled for replacement as required

maintenance in the owner's manual supplied, is warranted for the war-

ranty period stated above. If any such part fails during the period of

ering the performance of regular maintenance be retained in case

questions arise. If the engine is resold during the warranty period,

the maintenance records should be transferred to each subsequent

owner. Ardisam, Inc. reserves the right to deny warranty coverage if

the engine has not been properly maintained; however, Ardisam, Inc.

may not deny warranty repairs solely because of the lack of repair

maintenance or failure to keep maintenance records.

Normal maintenance replacement or repair of emission control devices

and systems may be performed by any repair establishment or individuals;

however, warranty repairs must be performed by an Ardisam authorized

service center. Any replacement parts or service that is equivalent in

performance and durability may be used in non-warranty maintenance

or repairs, and shall not reduce the warranty obligations of the engine

manufacturer.
