plug. Failure to follow these instructions can result in
serious personal injury or property damage.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1, along with hearing protection.
Failure to do so could result in objects being thrown into
your eyes and other possible serious injuries.
WARNING:
When servicing, use only recommended or equivalent re-
placement parts. Use of any other parts can create a hazard
or cause product damage.

ated by the USDA Forest Service and cannot be used on

Check with appropriate authorities. Contact customer
service or a qualified service center to purchase a re-

NOTICE:
Periodically inspect the entire product for damaged,

etc. Tighten securely all fasteners and caps and do not

GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most plastics
are susceptible to damage from various types of commercial
solvents and may be damaged by their use. Use clean cloths
to remove dirt, dust, lubricant, grease, etc.

MAINTENANCE

Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating lubricants, etc., come in con-
tact with plastic parts. Chemicals can damage, weaken or
destroy plastic which could result in serious personal
injury.
ACCESSING THE STRING HEAD
See Figure 15.
 Rotate mow ball with hex bolt clockwise to loosen.
 Remove mow ball with hex bolt from shaft.
To reattach mow ball:
 Slide mow ball with hex bolt onto shaft.
 Rotate counter clockwise to tighten.
CLEANING THE AIR INTAKE SCREEN
See Figure 16.
If the air intake screen becomes clogged or dirty, air circula-
tion will decrease and engine performance will suffer.
To clean:
 Stop the trimmer and disconnect the spark plug wire.
 Allow the unit to cool, if necessary.
 Using a dry cloth or nylon brush, remove dirt and debris
from screen.
IDLE SPEED ADJUSTMENT
See Figure 17.
The cutting head will move when adjusting the idle speed.
Wear all protective clothing and keep all by standers,
children, and pets at least 50 ft. away. Make adjustments
with the unit supported by hand so that the cutting head
does not contact the ground or any object. Keep all parts
of your body away from the cutting head and muffler.
Failure to follow these instructions could result in serious
personal injury.
If the cutting attachment turns at idle, the idle speed screw
needs adjusting on the engine. Turn the idle speed screw
counterclockwise to reduce the idle RPM and stop the cut-
ting attachment movement. If the cutting attachment still
moves at idle speed, contact a service dealer for adjustment
and discontinue use until the repair is made.
