REGULAR MAINTENANCE
AIR FILTER
The air filter should be cleaned each
time the power edger is used. (or
more often with extreme conditions.)
The filter
cover
can be removed by
unscrewing the single knob
(see
sketch).
Remove
the screen from the foam ring,
wash the foam in ker0sene or warm
detergent, then squeeze dry. Apply
oil
(#30
wt.) to foam, removing all
excess oil. Assemble and re-install
air filter on carburetor.
A
CAUTION-The air filter screen
is designed to fit the filter
cover ONE WAY ONLY ! It must
not be reversed! Refer to the
sketch and match the cuts in
the screen to the plastic
posts inside the filter cover.
(The fit should be snug.)
SPARK PLUG
The spark plug should be removed from
the engine and checked after each
25 hours of operation. The tips can
be cleaned with a stiff brush. Adjust
the gap to
0.024-0.028
inches (see
sketch). Replace the spark plug if it
is oil-fouled or damaged. The average
spark plug life is approximately
100
hours.
A
CAUTION-Do
not over-tighten
the spark plug. The correct
torque is
10-12
Ft.Lbs.
COOLING FINS
Free passage of air through the
cylinder cooling fins is required to
prevent poor engine performance and
shortened engine life.
Regularly
check and clean all debris from the
cooling fins by removing the engine
cover (see sketch).
