MAINTENANCE
WARNING:
When servicing, use only identical Homelite replacement
parts. Use of any other parts may create a hazard or
cause product damage.
WARNING:
Always wear safety goggles or safety glasses with side
shields during tool operation. If operation is dusty, also
wear a dust mask.
WARNING:
Before inspecting, cleaning, or servicing the machine,
shut off engine, wait for all moving parts to stop, and
disconnect spark plug wire and move it away from spark
plug. Failure to follow these instructions can result in
serious personal injury or property damage.
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.
WARNING:
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 may result in serious personal
injury.
You can often make adjustments and repairs described here.
For other repairs, have the trimmer serviced by an authorized
service dealer.
