MAINTENANCE INSTRUCTIONS (CONTINUED)
FUEL FILTER
When the
engine runs
short of fuel
supply and the
tank has
gasoline in it,
clean the fuel
filter for
blockage
(Fig. 34).
!
NOTE
If debris causes blockage
around the intake air cooling
vent or between the cylinder fins, it may
cause the engine
to overheat, and
that in turn may
cause mechanical
failure on the part
of the Atom Edger.
Remove air
deflector to clean.
CHECKING EXHAUST MUFFLER
Tighten exhaust screws. If exhaust gasket is leaking,
replace gasket. If the engine is low on power, check the
muffler. Allow motor to cool down. Remove and scrape
out excess carbon (Fig. 35) on both inlet and exit exhaust
or have this done by a service dealer. Replace exhaust
spark arrestor if worn, broken or blocked (Fig 36).
For Engine Troubleshooting see page 18 and 19.
