MAINTENANCE
REPLACING AND CLEANING AIR FILTER
See Figures 20 - 21.
For proper performance and long life, keep air filter clean.
n Remove the air filter cover by pushing down on the latch 
with your thumb while gently pulling on the cover.
n Remove the filter, clean  it in  warm soapy  water.  Rinse 
and  let dry  completely. For  best  performance,  replace 
annually.
n Install the filter, align tabs, push in, and make sure the 
latch snaps and latches into place.
FUEL CAP
WARNING:
A leaking fuel cap is a fire hazard and must be replaced 
immediately.
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 NGK # BPMR7A spark plug with .025 
in. (0.63 mm) electrode gap. Use an exact replacement and 
replace annually, or more frequently if necessary.
STORING  THE  TRIMMER  (1  MONTH  OR 
LONGER)
n Drain  all  fuel  from  tank  into  a  container  approved  for 
gasoline. Run engine until it stops.
n 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.
n 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.
