Engine Air Intake Screen:
B
Air Filter:
A
Your Trimmer has been equipped with two air filters inside the housing. Accumulated debris and dust in the air filter will
reduce engine performance, increase fuel consumption and increases the risk of engine damage. Clean the air filters
every 5 hours of operation. It may be necessary to clean the air filter more often in dry conditions due to a large amount
of airborn debris.
NOTICE
It is critical that the engine air intake screen be cleaned of debris to maintain acceptable engine temperatures. It is
recommended that the screen be cleaned every time the trimmer string is replaced.
WARNING
Disconnect the spark plug before performing maintenance.
WARNING
1. Before removing air filter cover, brush away any loose
dirt or debris on and around the pre-filter located in
the outer filter housing.
2. Remove air filter by unscrewing the retaining fastener.
(Fig. 28)
3. Remove and clean foam filter. (Fig. 30)
•
Light surface dust can readily be removed by
tapping the filter.
• Heavy deposits should be washed out in soap
and water. Squeeze out any remaining water and
allow the filter to completely dry.
Never clean filter in gasoline or other flammable solvents.
4. Add four drops of thin oil to the foam filter, squeeze
out excess and replace.
5. Remove the paper air filter element. (Fig 31) Clean
filter by gently tapping it on a flat surface. If very dirty,
replace with a new filter.
6. Reassemble the air filter element and air filter cover.
