MAINTENANCE
WARNINg:
When servicing, use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
WARNINg:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1. Failure to do so could result in
objects being thrown into your eyes, resulting in possible
serious injury.
WARNINg:
Before inspecting, cleaning, or servicing the machine,
shut off engine or motor, wait for all moving parts to stop,
and disconnect spark plug wire and move it away from
spark plug or disconnect from power supply. 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, oil, grease, etc.
WARNINg:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
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.
