11 MAINTENANCE
11.1 Air filter
CAUTION: NEVER operate trimmer without the air filter or dust and dirt will be
sucked into the engine and damage it. The air filter must be kept clean. If it
becomes damaged, install a new filter.
Accumulated dust in the air filter will reduce engine efficiency, increase fuel consumption
and allow abrasive particles to pass into the engine. Remove the air filter as often as
necessary to maintain in a clean condition.
Light surface dust can readily be removed by tapping the filter. Heavy deposits should be
washed out in soap water.
Remove filter cover by loosening air filter cover knob.
NOTE: Replace filter if frayed, torn, damaged or if it cannot be cleaned.
11.2 Fuel cap / fuel filter
CAUTION: Remove fuel from unit and store in approved container before
starting this procedure. Open fuel cap slowly to release any pressure which
may have formed in fuel tank.
Keep vent on fuel cap free of debris.
Lift fuel line and filter out of tank. A steel wire with a hook or a paper clip works well.
Pull off fuel filter with a twisting motion.
Replace the fuel filter.
NOTE: Never operate the tool without the fuel filter. Internal engine damage
could result and / or disturb a good operation.
When the inside of the fuel tank is dirty, it can be cleaned by rinsing the tank
out with gasoline.
