OIL & FUEL INFORMATION

4. Reinstall oil fill plug / dipstick into the crankcase.

NOTE: Save the bottle and funnel spout for

future use.

CHECKING THE OIL

The importance of checking and maintaining the proper oil
level in the crankcase cannot be overemphasized. Check
the oil BEFORE EACH USE as follows:

1. Make sure the engine is stopped, level (Fig. 16) and is
cool so the oil has had time to drain into the
crankcase.

2. To keep dirt, grass clippings, etc. out of the engine,
clean the area around the oil fill plug / dipstick before
removing it.

3. Remove the oil fill plug / dipstick; wipe the oil off.
Reinsert it into the crankcase. Thread the oil fill plug /
dipstick into the crankcase.

4. Remove the oil fill plug / dipstick and check the oil
level. The oil level should be up to the top of the dip­stick (Fig. 17).

5. If the level is low, add the oil to the top of the dipstick
(Fig. 17). Always check the level with the dipstick
before adding more oil.

NOTE: DO NOT ADD OIL TO THE FUEL.

THIS ENGINE IS CERTIFIED TO OPERATE ON UNLEADED GAS ONLY.

NOTE: BE SURE TO READ THESE

INSTRUCTIONS CAREFULLY BEFORE
ATTEMPTING TO START OR OPERATE
THIS UNIT. Using old or improper oil or
fuel can cause engine damage. This type
of damage will void the engine warranty.

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 high-quality SAE 30 weight oil of API (American

Petroleum Institute) service class SG, SF.

Fig. 14

ADDING OIL TO CRANKCASE - INITIAL
USE

Your unit is supplied with one bottle of oil, which contains
100 ml (3.4 fluid oz) of SAE 30 SF, SG oil (Fig. 14).

1. Open the bottle of oil.

2. Install the funnel spout.

RECOMMENDED FUEL TYPE

WARNING

Fuel is extremely flammable and its vapors can
explode if they are ignited. Always stop the
engine and allow it to cool before filling the fuel
tank. Do not smoke while filling the tank. Keep
sparks and open flames away from the area.

Fill the fuel tank, using clean, fresh, unleaded gasoline.

NOTE: Alcohol blended fuel absorbs moisture

(water). As little as 1% moisture in the
fuel can cause fuel to separate and form
acids when stored.

If this type of fuel must be used, use
fresh fuel (less than 60 days old).

DEFINITION OF BLENDED FUELS

Today's fuels are often a blend of gasoline and one or
more oxygenates such as ethanol, methanol or MTBE
(ether).

USE OF BLENDED FUELS

If you choose to use a blended fuel or its use is unavoid­able, the following precautions are recommended.

1. Always use fresh fuel.

2. Use the special additive GASOHOL GAS TREAT-

MENT® (by Gold Eagle) or an equivalent to inhibit
corrosion.

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

USE OF FUEL ADDITIVES

The use of fuel additive such as STA-BIL®Gas Stabilizer
or an equivalent, will inhibit corrosion and minimize the for­mation of gum deposit. Add (23 ml) 0.8 oz per gallon of
fuel per instructions on container. NEVER add fuel addi­tives directly to the unit's fuel tank. Using a fuel additive

can keep fuel fresh for up to six (6) months.

OIL & FUEL INFORMATION (Continued)

NOTE: Make sure the O-ring is in place on the

oil fill plug when checking and changing
the oil.

NOTE: To prevent extensive engine wear or

damage, always maintain the proper oil
level in the crankcase. Never operate the
engine with oil level below the bottom of
the dipstick.

Fig. 18

CHANGING THE OIL

For a new engine, change the oil after the first 10 hours of
operation. Thereafter, change the oil after every 25 hours
or before storing the unit for an extended period of time.

Change the oil while the engine is still warm. The oil will
flow freely and carry away more impurities.

Change the oil as follows:

1. Remove the oil fill plug / dipstick.

2. Pour the oil into a container by tipping the trimmer in
a vertical position (Fig. 18). Be sure to allow ample
time for complete drainage. Dispose of oil properly.

3. Fill the crankcase, with new oil of the proper type, to
the top of the dipstick. Use the bottle saved from the
initial use.

4. Reinstall the oil fill plug / dipstick and tighten securely.

OPERATING INSTRUCTIONS

Fig. 23

Fig. 24

NOTE: Always keep the trimming line fully

extended. Line release becomes more
difficult as cutting line becomes shorter.

Each time the head is bumped, about 25.4 mm (1 in) of
trimming line is released. A blade in the line guard will cut
the line to the proper length if excess line is released.

For best results, tap the head on bare ground or hard soil.
If line release is attempted in tall grass, the engine may
stall.

DECORATIVE TRIMMING

Decorative trimming is accomplished by removing all
vegetation around trees, posts, fences, etc. Use a
30-degree angle when trimming with this method (Fig. 24).

4. Start the engine and let it run for three (3) to five (5)
minutes with the throttle trigger fully squeezed.

5. Release the throttle trigger and let the engine idle. If
the engine stops, turn the idle speed screw (Fig. 40)
n (clockwise) 1/8 turn at a time (as required) until
the engine idles.

6. Final High Speed Mixture Needle Adjustment:

a. While squeezing the throttle trigger fully, set the

high speed mixture needle at the optimum setting
(Fig. 41). See “Definition of Optimum Setting” on
page 21.

7. Final Idle Speed Mixture Needle Adjustment: Adjust
the idle speed mixture needle for smoothest engine
idle using the following procedure. Do not squeeze
the throttle trigger when adjusting the idle speed mix­ture needle.

a. Set the idle speed mixture needle at the

optimum setting (Fig. 41). See “Definition of
Optimum Setting”.

b. Turn the idle speed mixture needle out

(counterclockwise) to the rich side of
optimum.

The engine should idle and accelerate smoothly.

This unit is equipped with a diaphragm-type carburetor
that has been carefully calibrated at the factory. In most
cases, no further adjustment will be required.

NOTE: To meet the 1995 California emission

regulations, the carburetor has adjust­ment needle limiter caps to restrict the
amount of adjustment.

The condition of the air filter is important to the operation
of the trimmer. A dirty air filter will restrict the air flow,
which upsets the fuel-air mixture in the carburetor. The
resulting symptoms are often mistaken for an out-of­adjustment carburetor. Therefore, check the condition of

the air filter before adjusting the carburetor. Refer to
Air Filter Maintenance.

If the following conditions are experienced, it may be nec­essary to adjust the carburetor:

• The engine will not idle

• The engine hesitates or stalls on acceleration

• The loss of engine power that is not corrected by

cleaning the air filter, muffler, spark arrester screen or
adjusting the valve clearance

• The engine operates in an erratic or fuel rich condition

The carburetor has three basic adjustments: the idle
speed, idle speed mixture and high speed mixture.

NOTE: The string guard and line spool must be

installed and the cutting line extended to
its full cutting length when making
carburetor adjustments.

Adjusting the Carburetor

1. Clean the air filter if it is dirty. Refer to Air Filter
Maintenance in the enclosed operator's manual.

2. Make the initial settings with the engine stopped.
These initial settings should allow you to start and
warm up the trimmer before making the final adjust­ments.

Initial Idle Speed Setting: Back the idle speed screw
(Fig. 40) out (counterclockwise) until it does not
contact the carburetor throttle lever. Then turn the
screw in (clockwise) until it just begins to move the
throttle lever; then continue turning 2 full turns.

3. Initial High Speed Mixture and Idle Speed Mixture
Settings: Turn both the high speed and idle speed
mixture needles halfway between the allowable
movement of the limiter caps.
