FUEL TYPE

Old fuel is the primary reason for improper unit
performance. Be sure to use fresh, clean, unleaded
gasoline.

Definition of Blended Fuels
Today's fuels are often a blend of 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 (less than 60 days
old), when using alcohol-blended fuel.

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 harmful deposits in
the carburetor for up to six (6) months. Add 0.8 oz.
(23 ml.) of fue! additive per gallon of fuel according to the
instructions on the container. NEVER add fuel additives
directly to the unit's gas tank.

TRIMMING

Keep the cutting attachment

RESULTS
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 8 inches (200 mm) by working from
top to bottom in small increments to avoid
premature line wear or engine drag.
Cut from right to left whenever possible. Cutting to
the left 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.

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. 18) while operating the trimmer at high speed.
NOTE: Always keep the trimming line fully extended.
Line release becomes more difficult when the
cutting line gets shorter.

Trim only when grass and weeds are dry.
The life of your cutting line is dependent upon:
Following the trimming techniques
What vegetation is being cut
Where vegetation is cut
For example, the line will wear faster when trimming
against a foundation wall as opposed to trimming
around a tree.

DECORATIVE

TRIMMING

Decorative trimming is accomplished by removing all
vegetation around trees, posts, fences and more.
Rotate the whole unit so that the cutting attachment is at
a 30 ° angle to the ground (Fig. 19).

Fig. 18
Each time the head is bumped, about 1 inch (25.4 mm)
of trimming line releases. A blade in the cutting
attachment shield will cut the line to the proper length if
any excess line is released.
For best results, tap the bump knob on bare ground or
hard soil. if you attempt a line release in tall grass, the
engine may stall. Always keep the trimming line fully
extended. Line release becomes more difficult when the
cutting line gets shorter.

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. 40).
NOTE: Careless adjustments can seriously damage your
unit. An authorized service dealer should make
carburetor adjustments.
Check Fuel

Fig. 36
Apply enough clean SAE 30 motor oil to lightly coat
the filter (Fig. 37).

Old fuel is usually the reason for improper unit
performance. Drain and refill the tank with fresh fuel prior
to making any adjustments. Refer to Oil and Fuel
Information.

Clean Air Filter

ROCKER

The condition of the air filter is important to the operation
of the unit. A dirty air filter will restrict air flow. 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.

This requires disassembly of the engine. If you feel
unsure or unqualified to perform this, take the unit to an
authorized service center.

Adjust Idle Speed Screw

NOTE: Inspect the valve to rocker arm clearance with a
feeler gauge after the first 10 hours of operation
and then every 25 hours of operation thereafter.
• The engine must be cold when checking or adjusting
the valve clearance.

ARM CLEARANCE

This task should be performed inside, in a clean,
dust free area.
1. Remove the muffler cover by pressing down on it,
separating it from the engine cover. Using a flat
blade screwdriver, disengage the middle and front
tabs and slots first. The cover will hinge off from the
rear tab (Fig. 41).

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 air filter/muffler cover (Fig. 40). 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.
