MAINTENANCE
REPLACING AND CLEANING AIR FILTER
See Figure 15.
A wet or dirty air filter can affect the way the engine starts,
performs, and wears.
The air filter should be checked and
cleaned after 8 hours of operation.
For best performance, the air filter should be replaced once
each year.
To clean the air filter:

Loosen the knob on the air filter cover.

Remove the cover.

Lift the edge of the air filter carefully and peel it out.

Wash the air filter with warm, soapy water.
 Rinse and squeeze to dry.

Reinstall the air filter.
NOTE: Make sure the filter is seated properly inside the
cover. Installing the filter incorrectly will allow dirt to enter
the engine, causing rapid engine wear.
 Reinstall the cover.

Tighten knob to secure.
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 RCJ4 with 0.63 mm
(0.025 in.) electrode gap. Use an exact replacement spark
plug and replace annually.
STORING THE PRODUCT

Clean all foreign material from the product. 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.

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.
