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.
REPLACING AND CLEANING AIR FILTER
See Figures 20 and 21.
For proper performance and long life, keep air filter clean.
1. Remove the air filter cover by pushing down on the latch
with your thumb while gently pulling on the cover.
2. Remove the filter, clean it in warm soapy water. Rinse
and let dry completely. For best performance, replace
annually.
3. Install the filter, align tabs, push in, and make sure the
latch snaps and latches into place.

A leaking fuel cap is a fire hazard and must be
replaced immediately.
