6. Use a wire brush to remove any exhaust deposits
that may have collected on the spark arrester
screen.
7. If the spark arrester screen shows signs of wear
such as rips, tears or large openings, it should be
replaced.
8. Reinstall the spark arrester components in the
following order:
a - Insert the spark arrester screen into its collar
and then slide this assembly onto the muffler
exhaust pipe. Take care to align one of the
slots in the collar with the locking screw. Push
the collar on firmly to ensure that the screen is
well seated and tighten the locking screw.
b - Place the spark arrester band clamp over the
collar with the gap in the band clamp aligned
with the collar locking screw. Then tighten the
adjusting screw on the band clamp.
9. Reinstall the muffler access cover.
CLEANING THE GENERATOR
The generator should be kept clean and dry at
all times to ensure its reliable and safe operation.
This must be checked each time before using the
generator.
Use a damp cloth which has been soaked in a mixture
of household detergent and warm water and then
wrung out to remove excess liquid. Wipe the exterior
surfaces of the generator clean and then repeat with a
damp cloth which has been rinsed in clean water and
wrung out. Finish by wiping off all moisture with a dry
cloth. Do not use abrasive or solvent cleaners.
A soft, non-metallic bristle brush or a vacuum cleaner
may be used to loosen and remove any built-up dirt,
mud or other debris. Low pressure compressed air
may also be used to blow off any dirt or dust.
