OIL TYPE

Using the proper type and weight of oil in the
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.

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

FUEL TYPE

FUELING

Old fuel is the primarj reason for the unit not
running properly. Be sure to use fresh, clean,
unleaded Petrol (gasoline).

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.

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 a blend 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.

injury from petrol (gasoline) spray.

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.

and body protection to reduce the risk of
ARNING: Always wear eye, hearing, foot
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
clothing,

and proper

•

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.

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 forwardbackward 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:

The Bump Head TM cutting attachment allows you to
release trimming line without stopping the engine. To

• 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

• 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

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.

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.

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).

,,Idle Adjustment Screw
/

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

Fig, 48

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

ROCKER

ARM CLEARANCE

This requires disassembly of the engine. If you feel
unsure or unqualified to perform this, take the unit to an
authorized service center.
NOTE: Inspect the valve to rocker arm clearance with a
feeler gauge after the first 10 hours of operation
and then every 50 hours of operation thereafter.
• The engine must be cold when checking or adjusting
the valve clearance.
• This task should be performed inside, in a clean, dust
free area.
