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 performance.
If performance improves when the fuel cap is loosened, check
valve may be faulty or filter clogged. Replace fuel cap if
required.
SPARK PLUG
This engine uses a Champion RCJ-6Y or NGK BPMR7A
spark plug with .025 in. (0.63 mm) electrode gap. Use an
exact replacement and replace annually, or more frequently
if necessary.
STORAGE (1 MONTH OR LONGER)
n Drain all fuel from tank into a container approved for
gasoline. Run engine until it stops.
n 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.
n Abide by all Federal and local regulations for the safe
storage and handling of gasoline. Excess fuel should be
used up in other 2-cycle engine powered equipment.
