Replacing and Cleaning AIR Filter, Spark Arrestor

MAINTENANCE

REPLACING AND CLEANING AIR FILTER

See Figure 14.

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:

nLoosen the knob on the air filter cover.

nRemove the cover.

nLift the edge of the air filter carefully and peel it out.

nWash the air filter with warm, soapy water.

nRinse and squeeze to dry.

nReinstall 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.

nReinstall the cover.

nTighten knob to secure.

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. If the bag has deteriorated from normal use, to obtain a replacement bag, consult your replacemnt parts list.

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.

STORAGE (1 MONTH OR LONGER)

nDrain all fuel from the tank into a container approved for gasoline. Run engine until it stops.

nClean 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.

nAbide 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.
