MAINTENANCE
CLEANING THE AIR FILTER SCREEN
See Figures 17 - 18.
For proper performance and long life, keep air filter screen
clean.
Remove the hex nut, wavy washer, flat washer, and choke
dial cover.
Brush the air filter screen lightly to clean.
Reinstall the choke dial cover, flat washer, wavy washer,
and hex nut.
FUEL CAP
WARNING:
A leaking fuel cap is a fire hazard and must be replaced
immediately.
The fuel cap contains a non-serviceable filter and a check
valve. A clogged fuel filter will cause poor engine perfor-
mance. If performance improves when the fuel cap is loos-
ened, check valve may be faulty or filter clogged. Replace
fuel cap if required.
SPARK PLUG
This engine uses a Champion RCJ6Y or equivalent spark
plug with .025 in. electrode gap. Use an exact replacement
and replace annually, or more frequently if necessary.
STORING THE TRIMMER
Clean all foreign material from the trimmer. Store it in a
well-ventilated place that is inaccessible to children. Keep
away from corrosive agents such as garden chemicals
and de-icing salts.
Abide by all Federal and local regulations for the safe
storage and handling of gasoline.
WHEN STORING 1 MONTH OR LONGER:
Drain all fuel from tank into a container approved for
gasoline. Run engine until it stops.
