SAFETY RULES

Safe Operation Practices for Trimmer.

WARNING: Look for this symbol to point out important safety precautions.
It means: “Attention! Become Alert! Your Safety Is Involved.”

I. General Operation

1. Read, understand, and follow all instruc­tions on the machine and in the manual(s).
Be thoroughly familiar with the controls and
the proper use of the trimmer before start­ing.

2. Familiarize yourself with all of the safety
and operating decals on this equipment
and on any of its attachments or accesso­ries.

3. Do not put hands or feet near or under rotat­ing parts.

4. Only allow responsible individuals, who are
familiar with the instructions, to operate the
trimmer.

5. Inspect the area where the trimmer is to be
used. Your equipment can propel small ob­jects at high speed causing personal injury
or property damage. Stay away from
breakable objects, such as house win­dows, auto glass, greenhouses, etc.

6. Keep the area of operation clear of all per­sons, particularly small children, and pets.

7. Wear appropriate clothing such as a long­sleeved shirt or jacket. Also wear long trou­sers or slacks. Do not wear shorts.

8. Do not wear loose clothing which could get
caught in this equipment.

9. Always wear safety goggles or safety
glasses with side shields when operating
trimmer to protect your eyes from foreign
objects which can be thrown from the unit.

10. Always wear work gloves and sturdy foot­wear. Leather work shoes or short boots
work well for most people. These will pro­tect the operator’s ankles and shins from
small sticks, splinters, and other debris,
and improve traction.

11. It is advisable to wear protective headgear
to prevent the possibility of being struck by
small flying particles, or being struck by low
hanging branches, twigs, or other objects
which may be unnoticed by the operator.

12. Do not operate the trimmer without proper
guards or other safety protective devices
in place.

13. Use this equipment for its intended pur­pose only.

14. See manufacturer’s instructions for proper
operation and installation of accessories.

F-050204L

Only use accessories approved by the
manufacturer.

15. Operate only in daylight or good artificial
light.

16. Do not operate the trimmer while under the
influence of alcohol, drugs or other medica­tion which can cause drowsiness or affect
your ability to operate this machine safely.

17. Never operate trimmer in wet grass. Al­ways be sure of your footing; keep a firm
hold on the handle and walk; never run.

18. Before each use, inspect the throttle con­trol lever and cable. Make sure that the
cable is free and that the lever is not dam­aged. Also check the cable linkage running
to the carburetor for kinks, loose fittings,
and obstructions. Verify that the control
bail is working properly.

19. Stop the rotating trimmer head when cross­ing gravel drives, walks, or roads. Wait for
the cutting lines to stop rotating.

20. Watch for traffic when operating near, or
when crossing roads.

21. Stop the engine (motor) whenever you
leave the equipment, before cleaning re­pairing or inspecting the unit, be sure the
trimmer head and all moving parts have
stopped. Let the engine cool, disconnect
the spark plug wire and move it away from
the spark plug.

22. If the equipment should start to vibrate ab­normally, stop the engine (motor), discon­nect the spark plug wire and prevent it from
touching the spark plug. Check immediate­ly for the cause. Vibration is generally a
warning of trouble.

23. After striking a foreign object, stop the en­gine (motor). Remove the wire from the
spark plug. Inspect the trimmer for dam­age. If damaged, repair before starting and
operating the trimmer.

24. Never leave the trimmer unattended when
the engine is running. Remove the wire
from the spark plug.

25. Regularly inspect the trimmer. Make sure
parts are not bent, damaged or loose.

II. Slope Operation

Slopes are a major factor related to slip and fall
accidents which can result in severe injury. All

3

slopes require extra caution. If you feel uneasy

SAFETY RULES

on a slope, do not trim it.
Do trim across the face of slopes; never up and

down. Do not trim excessively steep slopes
(maximum 15 degrees) or areas where the
ground is very rough. See the “Guide” in the
back of this manual to check a slope. Exercise
extreme caution when changing direction on
slopes.

Do remove objects such as rocks, tree limbs,
etc.

Do watch for holes, ruts, or bumps. Tall grass
can hide obstacles.

Do not trim near drop-offs, ditches, or embank­ments. The operator could lose footing or bal­ance.

Do not trim excessively steep slopes.
Do not trim on wet grass. Reduced footing

could cause slipping.

III. Children

Tragic accidents can occur if the operator is not
alert to the presence of children. Children are
often attracted to the trimmer and the trimming
activity. Never assume that children will remain
where you last saw them.

1. Keep children out of the trimming area and
under the watchful care of a responsible
adult.

2. Be alert and turn trimmer off if children en­ter the area.

3. Before and while moving backwards, look
behind and down for small children.

4. Never allow children to operate the trim­mer.

5. Use extra care when approaching blind
corners, shrubs, trees, or other objects that
may obscure vision.

IV. Service

1. Use extra care in handling gasoline and
other fuels. They are flammable and va­pors are explosive.

a. Use only an approved container.

b. Never remove gas cap or add fuel with

the engine running. Allow engine to
cool before refueling. Do not smoke.

c. Never refuel the machine indoors.

d. Never store the machine or fuel con-

tainer inside where there is an open
flame, such as a water heater.

2. Never run an engine indoors or inside a
closed area.

3. Never make adjustments or repairs with
the engine (motor) running. Disconnect the
spark plug wire, and keep the wire away
from the plug to prevent accidental starting
(remove the ignition key if equipped with an
electric start). Always wear eye protection
when you make adjustments or repairs.

4. Check the trimmer head and engine
mounting bolts at frequent intervals for
proper tightness.

5. Keep all nuts and bolts tight and keep
equipment in good condition. Check
mounting hardware on trimmer head every
time you change trimmer line and prior to
each use.

6. Never tamper with safety devices. Check
their proper operation regularly.

7. When servicing or repairing the trimmer, do
not tip the machine over or up unless spe­cifically instructed to do so in this Manual.
Service and repair procedures can be done
with the trimmer in an upright position.
Some procedures will be easier if the ma­chine is lifted on a raised platform or work­ing surface.

8. To reduce fire hazard, keep trimmer free of
grass, leaves, or other debris build-up.
Clean up oil or fuel spillage. Allow trimmer
to cool before storing.

9. Stop and inspect the equipment if you
strike an object. Repair, if necessary, be­fore restarting.

10. Always disconnect spark plug wire before
cleaning, repairing, or adjusting.

11. Do not change the engine governor setting
or over-speed the engine.

12. Clean and replace safety and instruction
decals as necessary.

13. To guard against engine over-heating, al­ways have engine debris filter mounted
and clean.

14. Inspect trimmer before storage.

15. Use only original equipment or authorized
replacement parts.

TRIMMER TIPS

WARNING: Debris such as sticks,
gravel or rocks, can be thrown
with sufficient force to cause per­sonal injury or property damage.

S Set the throttle control in the FAST posi-

tion. If the weeds or grass are tall and
thick, operate the trimmer at a slower
walking speed.

S Frequently clean the underside of the trim-

mer to remove any grass build up. See the
Maintenance section for details.

S For best results and longer lasting line,

use the ends of the line to do the cutting.
This is easily done by moving slowly
through very thick or heavy weeds.

S If the trimmer lines become too short, it will

F-050204L

take longer to complete the job. If the trim­mer lines are worn to less than half their
original length, change to a new trimmer
line. “See How To Change The Trimmer
Line” in the Service And Adjustment sec­tion.

S Do not trim on excessively steep slopes. If

a slope is difficult to stand on, do not trim.
Do not trim on slopes when the ground is
slippery or wet. Trim across the face of a
slope, not up and down.

S Trimmer head contact to concrete, asphalt

and harder services may create prema­ture wear to the height guide (See
Figure 13).

SERVICE AND ADJUSTMENT

SERVICE AND ADJUSTMENT

WARNING: Before you inspect, clean or service the trimmer, stop the engine.
Make sure that all moving parts have stopped. Disconnect the wire from the
spark plug.

HOW TO
REPLACE THE TRIMMER LINE

For the best performance, use a heavy
gauge (0.155” diameter) trimmer line. Cut
the length of the trimmer line to 21.5 inches.
Use the length guide, located on the shield,
to make sure the trimmer line is the correct
length. See Figure 11. Do not allow the
length of the lines to vary more than one
inch. This is important to make sure the trim­mer head is balanced and does not vibrate.

IMPORTANT: To extend the life of the trim­mer line, keep the trimmer line moist. If not
kept moist, the nylon trimmer line will be­come dry and brittle. Keep extra trimmer
line in a can of water. The line will then stay
flexible and easy to change. A flexible line
will also last much longer.

HOW TO CHANGE TRIMMER LINES

When the trimmer line becomes worn to half the original length, replace the trimmer line as
follows:

SERVICE AND ADJUSTMENT

STORAGE

WARNING: Do not remove gaso­line while inside a building, near
a fire, or while you smoke. Gaso­line fumes can cause an explo­sion or a fire.

When the trimmer is put in storage for thirty
days or more, follow the steps below to
make sure the trimmer is in good condition
the following season.

Trimmer

S Completely clean the trimmer.

S Put the trimmer in a building that has good

ventilation.

NOTE: A yearly checkup or tune-up at an
authorized service center will make sure
that the trimmer will provide maximum per­formance for the next season.

Engine

IMPORTANT: It is important to prevent gum
deposits from forming in fuel system parts
such as the carburetor, fuel filter, fuel hose,
and tank during storage. Also, using alco­hol-blended fuels (called gasohol, ethanol
or methanol) can attract moisture which
leads to separation and formation of acids

during storage. Acidic gas can damage the
fuel system of an engine while in storage.

To prevent engine damage when the trimmer
is in storage for 30 days or more, follow the
steps below:

S Let the engine run until it is out of gasoline.

S Drain the oil from the warm engine. Fill the

engine crankcase with new oil.

S Remove the spark plug from the cylinder.

Pour one ounce of oil into the cylinder.
Slowly pull the recoil starter handle so that
the oil will protect the cylinder. Install a new
spark plug in the cylinder.

S Clean dirt and debris from the cylinder

cooling fins and the engine housing.

S If you do not want to remove gasoline, add

a fuel stabilizer to any gasoline left in the
tank. Fuel stalibizer will minimize the
formation of gum deposits and acids. If the
tank is almost empty, mix the fuel stabilizer
with fresh gasoline in a separate container
and add the mixture to the tank. Always
follow the instructions on the stabilizer
container. Run the engine at least ten min­utes after stabilizer is added to allow the
mixture to reach the carburetor.
