MAINTENANCE
SPARK ARRESTOR
The muffler is equipped with a spark arrestor screen inside
muffler body. After extended use the screen can become
dirty and the screen may need to be replaced by an autho-
rized servicing dealer.
WARNING:
To avoid a fire hazard, never run the blower without the
spark arrestor in place.
CLEANING THE EXHAUST PORT AND MUFFLER
Depending on the type of fuel used, the type and amount of
oil used, and/or your operating conditions, the exhaust port,
muffler, and/or spark arrestor screen may become blocked
with carbon deposits. If you notice a power loss with your
gas powered tool, you may need to remove these deposits
to restore performance. We highly recommend that only
qualified service technicians perform this service.
FUEL CAP
The fuel cap contains a non-serviceable filter and a check
valve. A clogged fuel filter will cause poor engine per-
formance. If performance improves when the fuel cap is
loosened, the check valve may be faulty or filter clogged.
Replace the fuel cap if required.
WARNING:
A leaking fuel cap is a fire hazard and must be replaced
immediately.
SPARK PLUG
This engine uses a Champion RCJ4 with 0.63 mm
(0.025 in.) electrode gap. Use an exact replacement and
replace annually.
STORAGE (1 MONTH OR LONGER)
n Drain all fuel from the tank into a container approved for
gasoline. Run engine until it stops.
n Clean all foreign material from the blower. 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.
