STOP

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
loosened, check valve may be faulty or filter clogged.
Replace fuel cap if required.

SPARK PLUG

This engine uses a NSK # BPMR7A spark plug with
.025 in. (0.63 mm) electrode gap. Use an exact replace-
ment and replace annually, or more frequently if necessary.

STORING THE TRIMMER (1 MONTH OR
LONGER)

1. Drain all fuel from tank into a container approved for

gasoline. Run engine until it stops.

2. 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.

3. 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.
