CLEANING THE AIR FILTER SCREEN

See Figures 16 - 17.

For proper performance and long life, keep air filter screen clean.

Remove the air filter cover by pushing down on the latch with your thumb while gently pulling on the cover.

Brush the air filter screen lightly to clean.

Replace the air filter cover by inserting the tabs on the bottom of the cover into the slots on the air filter base; push the cover up until it latches securely in place.

FUEL CAP

WARNING:

Check for fuel leaks. A leaking fuel cap is a fire hazard and must be replaced immediately. If you find any leaks, correct the problem before using the product. Failure to do so could result in a fire that could cause serious personal injury.

The fuel cap contains a non-serviceable filter and a check valve. A clogged fuel filter will cause poor engine perfor- mance. If performance improves when the fuel cap is loos- ened, check valve may be faulty or filter clogged. Replace fuel cap if required.

SPARK PLUG

This engine uses a Champion RCJ6Y or equivalent spark plug with .025 in. electrode gap. Use an exact replacement and replace annually, or more frequently if necessary.

STORing the trimmer

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.

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.

TROUBLESHOOTING

Problem

Engine will not start.

Possible Cause

No spark.

No fuel.

Engine is flooded.

Starter rope pulls harder now than when new.

Solution

Check spark. Remove spark plug. Re- attach the spark plug cap and lay spark plug on metal cylinder. Pull the starter rope and watch for spark at spark plug tip. If there is no spark, repeat test with a new spark plug.

Push primer bulb until bulb is full of fuel. If bulb does not fill, primary fuel delivery system is blocked. Contact a servicing dealer. If primer bulb fills, engine may be flooded, proceed to next item.

Remove spark plug, turn trimmer so spark plug hole is aimed at the ground. Rotate the choke dial to “RUN” posi- tion and pull starter cord 10 to 15 times. This will clear excess fuel from engine. Clean and reinstall spark plug. Pull starter three times with choke dial at “RUN”. If engine does not start, ro- tate choke dial to “FULL CHOKE” posi- tion and repeat normal starting proce- dure. If engine still fails to start, repeat procedure with a new spark plug.

Contact a servicing dealer.
