Service

5
The operation of any mower can encounter foreign objects to be thrown into the eyes, resulting in
severe eye damage. Always wear certified safety glasses or wide-vision safety goggles over
spectacles before starting any cutting machine and while operating such a machine.
The operation of any mower produces sound waves that are damaging to the human ear. Ear
protection is recommended.
CAUTION!
Tragic accidents can occur if the operator is not alert to the presence of children. Children
are often attracted to the machine and the mowing activity. Never assume that children
will remain where you last saw them.
Do not operate the trimmer if it vibrates abnormally. Excessive vibration is a sign of damage.
Stop the engine and safely check for damage and repair as required.

Trimming Tips
Troubleshooting
•If engine will not start, remove and check air filter to make sure filter and
carburetor are clean.
•
Do not lift the trimmer head when trimming. Let the head rest lightly touching the ground.
•Keep an eye on the length of the trimmer line. As the line gets shorter they become less effective
at cutting and will take longer to trim properly. Replace the line as necessary (see Installing
Trimmer Line).
•Do not trim wet grass.
•Use caution when trimming slopes.
•Use the proper length of line. Using a line too long for the unit will cause stalling and
unacceptable operation.
Make sure your trimmer is in safe working condition by keeping the following guidelines in mind every time you
use your trimmer.
•Keep trimmer in good operating condition and keep all guards and shields in place. DO NOT operate this
trimmer if any of the shields and guards are missing.
•Check all fasteners for secure fit to keep equipment in safe working order. Make adjustments as necessary.
•To reduce fire hazards, keep engine free of grass, leaves or excessive grease.
•DO NOT operate trimmer with a damaged or missing muffler. DO NOT tamper with exhaust system; this may
cause a fire hazard.
•DO NOT operate engine if air cleaner or the cover over the carburetor air intake is missing. Removal of these
parts could create a fire hazard.
•Before cleaning, making adjustments or repairing the trimmer, STOP engine, disconnect spark plug wire and
allow engine to cool.
•Handle gasoline with care. DO NOT smoke or use open flame near gasoline. Use only approved gasoline
containers. Never fuel or run trimmer in poorly ventilated areas, such as a garage or utility building.
•Always replace fuel tank cap. Be sure to clean up any spilled gasoline.
•Do not change the engine governor settings or over-speed the engine; severe injury or damage may result.
•Never store mower with gasoline in the tank inside a building where fumes may reach an open flame or spark.
Always allow engine to cool before storing.
Trimmer Maintenance

Belts
•Occasionally check the belt for wear. A worn belt should be replaced.
Belt Adjustment
During the first few hours of operation all belts go through a “break-in period” after which the belts
may need to be adjusted using the following instructions. Indications that the belts need to be
adjusted include:
•Loss of power at the trimming head causing the head to spin unusually slow or stop.
•Excessive wear on belt due to slipping.
•The belt used to engage/disengage the trimmer head can be adjusted using the following
instructions:
1. Locate the thumb wheel adjuster on the control cable
(see illustration) .
2. Release control bail to disengage trimmer head.
3. Rotate thumb wheel a few turns counterclockwise (from normal operating position).
4. Re-engage trimmer head.
5. If trimmer head has not returned to normal operation, repeat steps 2-4.
Important! Do not over tighten cable adjuster. This may cause the cable to break.
Excessive force should NOT be required to fully engage control bail.
