RECOMMENDED OIL TYPE

Using the proper type and weight of oil in the

_crankcase is extremely important. Check the

oil before each use and change the oil

regularly. Failure to use the correct oil, or

using dirty oil, can cause premature engine wear and

failure.

Use a high-quality SAE 30 weight oil of API (American

Petroleum Institute) service class SF, SG, SH.

ADDING OIL TO CRANKCASE - INITIAL USE

NOTE: This unit is shipped without being filled with oil.

In order to avoid damage to the unit, put oil in

the crankcase before attempting to start unit.

Your unit is supplied with one 100 ml (3.4 oz,)

bottle of SAE 30 SF, SG, SH oil (Fig. 17).

NOTE: Save the bottle to measure the correct amount

for future oil changes, See Changing the Oil

Pg. 21.

NOTE: Your new 4-Cycle trimmer is shipped for operation

in conditions above 4°C (40°F). For cold weather

operation, temperatures below 4°C (40°F) use a

high-quality SAE 10W30 weight oil of API

RECOMMENDED FUEL TYPE

Old fuel is the primarj reason for the unit not

running properly. Be sure to use fresh, clean,

unleaded Petrol (gasoline).

NOTE: This is a four cycle engine. In order to avoic_

damage to the unit, do not mix oil with Petrol

(gasoline).

Definition of Blended Fuels

Today's fuels are often ablend of petrol [gasoline) and

oxygenates such as ethanol, methanol or MTBE (ether).

Alcohol-blended fuel absorbs water. As little as 1%

water in the fuel can make fuel and oil separate or form

acids when stored. Use fresh fuel (leas than 60 days

old), when using alcohol-blended fuel.

Using Blended Fuels

If you choose to use a blended fuel, or its use is

unavoidable, follow recommended precautions.

• Always use fresh unleaded petrol (gasoline)

• Use the fuel additive STA-BIL ® or an equivalent.

• Drain tank and run the engine dry before storing unit.

Using Fuel Additives

The use of fuel additives, such as STA-BIL ® Gas

Stabilizer or an equivalent, will inhibit corrosion and

minimize the formation of gum deposits. Using a fuel

additive can keep fuel from forming _armful deposits in

the carburetor for up to six (6) months. Add 23 ml

(0.8 oz.) of fuel additive per gallon of fuel according to

the instructions on the container. NEVER add fuel

additives directly to the unit's petrol (gasoline) tank.

FUELING UNIT

WARNING: Petrol (gasoline) is extremely

flammable and its vapors can explode if

ignited. To avoid serious personal injury,

always stop the engine and allow it to cool

before filling the fuel tank. Do not smoke

whilst filling the tank. Keep sparks and open

flames away from the area.

a source of ignition for spilt fuel.

NOTE: Do not overfill tank.

3. Wipe up any petrol (gasoline) that may have spilled

4. Reinstall the fuel cap.

WARNING: Never operate the unit without

HOLDING THE TRIMMER

_ARNING: Always wear eye, hearing, foot i

and body protection to reduce the risk of

injury when operating this unit.

Before operating the unit, stand in the operating position

(Fig. 27). Check for the following:

• The operator is wearing eye protection and proper

clothing,

•The right arm is slightly bent, and the hand is holding

the shaft grip.

• The left arm is straight, and the hand is holding the

J-handle.

• The unit isat waist level.

Fig. 27

ADJUSTING TRIMMING LINE LENGTH

The Bump Head TM cutting attachment allows you to

release trimming line without stopping the engine. To

release more line. lightly tap the cutting attachment on

the ground (Fig. 28) whilst operating the trimmer at high

speed.

NOTE: Always keep the trimming line fully extended.

Line release becomes more difficult as cutting

ine becomes shorter

Each time the head is bumped, about 25.4 mm (1 inch)

of trimming line is released. A blade in the cutting

attachment guard will cut the line to the proper length if

excess line is released.

For best results, tap the Bump Head TM on bare ground

or hard soil. If line release is attempted in tall grass, the

engine may stall. Always keep the tdmming line fully

extended. Line release becomes more difficult as the

cutting line becomes shorter.

NOTE: Do not rest the Bump Head TM on the ground

whilst the unit is running.

CAUTION: Do not remove or a ter the line

cutting blade assembly. Excessive line length

will make the clutch overheat. This may lead I

to serious personal injury or damage to the

unit.

Some line breakage wiU occur from:

• Entanglement with foreign matter

• Normal line fatigue

• Attempting to cut thick, stalky weeds

• Forcing the line into objects such as walls or fence

posts

TIPS FOR BEST TRIMMING RESULTS

•Keep the cutting attachment parallel to the ground.

• Do not force the cutting attachment. Allow the tip of

the line to do the cutting, especially along walls.

Cutting with more than the tip will reduce cutting

efficiency and may overload the engine.

• Cut grass over 200 mm (8 inches) by working from

top to bottom in small increments to avoid

premature line wear or engine drag.

• Cut from left to right whenever possible. Cutting to

the right improves the unit's cutting efficiency,

Clippings are thrown away from the operator.

• Slowly move the trimmer into and out of the cutting

area at the desired height. Move either in a forward-

backward or side-to-side motion. Cutting shorter

lengths produces the best results.

• Tdm only when grass and weeds are dry.

• The life of your cutting line is dependent upon:

• Following the previous trimming techniques

• What vegetation is being cut

• Where it's being cut

For example, the line will wear faster when trimming

against a foundation wall as opposed to trimming

around a tree.

Fig, 28

DECORATIVE TRIMMING

Decorative trimming is accomplished by removing al!

vegetation around trees; posts, fences, etc.

Rotate the whole unit so that the Cutting attachment is at

a 30 °angle to the ground (Fig. 29).

USING THE CUTTING BLADE

I_ WARNING: Always wear eye, hearing, foot, I

body protection and the strap to reduce the

risk of injury when operating this unit.

,_ WARNING: Do not use the cutting blade for

edging or as an edger, severe personal injury

to yourself or others can occur. 1

Before operating the unit with the cutting blade stand in

the operating position (Figs. 30). Refer to Holding the

Trimmer, Pg. 17.

Cutting Blade Operating Tips:

To establish a rhythmic cutting procedure:

• Plant feet firmly, comfortably apart.

•Bring the engine to full throttle before entering the

matedal to be cut. The blade has maximum cutting

power at full throttle and is less likely to bind, stall, or

cause kick back, which can result in serious personal

injury to the operator or others.

i_k, ARNING: Kick back may occur when the

spinning blade contacts an object that it

does not immediately cut. Kick back can be

violent enough to cause the unit and/or

operator to be propelled in any direction, and

possibly lose control of the unit. Kick back

can occur without warning if the blade snags,

stalls or binds. This is more likely to occur in

areas where it is difficult to see the material

being cut.

Cut whilst swinging the upper part of your body from

right to left.

•Always release the throttle trigger and allow the engine

to return to idle speed when not cutting.

• When done always unsnap unit from harness before

taking harness off.

I_hl WARNING: The blade continues to spin after]

the engine is turned off, The coasting blade I

can seriously cut you if accidentally touched. J

• Swing the unit in the same direction as the blade

spins, which increases the cutting action.

* Move forward to the next area to be cut after the

return swing and plant feet again.

• The cutting blade is designed with a second cutting

edge, which can be used by removing the blade,

turning it upside down, and reinstalling it.

WARNING: Do not sharpen the cuffing

blade. Sharpening the blade can cause the

blade tip to break off whilst in use. This can

result in severe personal injury to yourself or

others. Replace the blade.

To reduce the chance of material wrapping around the

blade, follow these steps:

Cut at full throttle.

g Swing the unit into material to be cut from your right to

your left (Fig. 31).

• Avoid the material just cut as you make the return

swing.

WARNING: Do not clear away cut material I

with the engine running or blade turning. To I

avoid serious personal injury, turn off engine,

Allow the blade to stop before removing

materials wrapped around the blade shaft.

CARBURETOR ADJUSTMENT

The idle speed of the engine is adjustable. An idle

adjustment screw is reached though a hole in the top of

the engine cover (Fig 48).

NOTE: Careless adjustments can seriously damage your

unit. An authorized service dealer should make

carburetor adjustments.

Check Fuel

Old fuel is usually the main reason for the unit nol

running properly. Drain and refill the tank with clean,

fresh unleaded fuel prior to doing any adjustments. Refer

to Oil and Fuel Information.

Clean Air Filter

The condition of the air filter is importanl to the

operation of the unit. A dirty air filter will restrict air flow

and change the air/fuel mixture. This is often mistaken

for an out of adjustment carburetor. Check the condition

of the air filter before adjusting the idle speed screw.

Refer to Air Filter Maintenance.

Adjust Idle Speed Screw

WARNING: The cutting attachment may be

spinning during idle speed adjustment. Wear I

protective clothing and observe all safety I

instructions to prevent serious personal

injury.

If after checking the fuel and cleaning the air

filter the engine still will not idle, adjust the idle speed

screw as follows.

1. Start the engine and let it run at a high idle for a

minute to warm up.

2. Release the throttle trigger and let the engine idle. If

the engine stops, insert a small phillips or flat blade

screwdriver into the hole in the engine cover

(Fig. 48). Turn the idle speed screw in, clockwise,

1/8 of a turn at a time (as needed) until the engine

idles smoothly.

NOTE: The cutting attachment should not rotate when

the engine idles.

3. If the cutting attachment rotates when the engine

idles, turn the idle speed screw counterclockwise 1/8

of a turn at a time (as needed), to reduce idle speed.

Checking the fuel, cleaning the air filter, and adjusting

the idle speed screw should solve most engine

problems.

If not and:

• The engine will not idle,

• The engine hesitates or stalls on acceleration,

• There is a loss of engine power,

have the carburetor adjusted by an authorized service

dealer.

WARNING: When the unit is turned off make I

sure the cutting attachment has stopped I

before the unit is set down to preverlt serious

personal injury.
