CLEANING THE AIR FILTER SCREEN
See Figure 15 - 16.
For proper performance and long life, keep the 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.
SPARK ARRESTOR
The muffler is equipped with a spark arrestor screen inside
muffler body. After extended use the screen can become
dirty, and you may need to have the screen replaced by an
authorized 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.
VACUUM BAG
A dirty bag will reduce performance. To clean the bag, turn it
inside out and shake. Wash the bag in soapy water at least
once a year. To obtain a replacement bag, see How to Order
Replacement Parts on the back page of this manual.
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 RCJ6Y with 0.63 mm
(0.05 in.) electrode gap. Use an exact replacement spark
plug and replace annually.
