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.
Do not at any time let brake fluids, petrol, petroleum-
based products, penetrating lubricants, 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 in
this manual. For other repairs, have the trimmer serviced
by an authorised service dealer.

CHECKInG THE fUEl CaP

A leaking fuel cap is a fire hazard and must be replaced
immediately.
The fuel cap contains a non-serviceable filter and
check valve. A clogged fuel filter causes poor engine
performance. If performance improves when the fuel cap
is loosened, the check valve may be faulty or the filter may
be clogged. Replace the fuel cap if necessary.
