WARNING
• Before cleaning, the inspecting or repairing the unit,
make sure that engine has stopped and is cool. Discon-
nect the spark plug to prevent accidental starting.
■ MAINTENANCE AFTER EACH USE
1. Air filter
Dust on the cleaner surface can be removed by tapping
a corner of the cleaner against a hard surface. To clean
dirt in the meshes, split the cleaner into halves and brush
in gasoline. When using compressed air, blow from the
inside.
To assemble the cleaner halves, press the rim until it
clicks.
NOTE
When installing the main filter, make sure that the grooves
on the filter edge are correctly fit with the projections on
the cylinder cover.
