Neglected or poorly conducted maintenance may
create additional hazards. Do not attempt to repair or
maintain this product if you are not qualifi ed to do so.
If in doubt, return to a service centre for professional
assistance.
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.
Do not at any time let brake fl uids, 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 a service dealer.
CLEANING THE AIR FILTER (FIG. 9)
A dirty air fi lter will cause starting diffi culty, loss of
performance, and shorten the life span of the engine.
Check the air fi lter monthly. For best performance, replace
the air fi lter at least once a year.
■ Loosen the air filter cover (item 21) by turning the knob
(item 22) counterclockwise.
■ Remove the air filter (item 20).
■ Clean the foam filter element with warm soapy water.
Rinse and let dry.
NOTE: If the foam fi lter element is damaged, it should be
replaced.
■ Apply a light coat of engine oil to the foam filter
element, then squeeze it out.
■ Reinstall the air filter.
NOTE: Make sure the fi lter is seated properly inside the
cover. Installing the fi lter incorrectly will allow dirt to enter
the engine, causing rapid engine wear.
■ Reinstall the cover and tighten knob to secure.
Make sure the trimmer head stops rotating when you
release the trigger. Contact with a rotating trimmer head
could cause personal injury.

CHECKING THE FUEL CAP
A leaking fuel cap is a fi re hazard and must be replaced
immediately.
The fuel cap contains a non-serviceable fi lter and
check valve. A clogged fuel fi lter causes poor engine
performance. If performance improves when the fuel cap
is loosened, the check valve may be faulty or the fi lter may
be clogged. Replace the fuel cap if necessary.
REPLACING THE SPARK PLUG (FIG. 10)
This engine uses a Champion RCJ6Y or NGK BPMR7A
spark plug. Use an exact replacement and replace
annually.
Follow these steps to replace the spark plug.

■ Loosen the spark plug (item 24) by turning it
counterclock wise with a 16mm socket.
