MAINTENANCE
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
and muffler may become blocked with carbon deposits. If
you notice a power loss with your gas powered tool, a quali-
fied service technician will need to remove these deposits
to restore performance.
SPARK ARRESTOR
The spark arrestor must be cleaned or replaced every 25 hours
or yearly to ensure proper performance of your product. For
the location of the spark arrestor and specific cleaning in-
structions, contact your nearest authorized service center.
REPLACING AND CLEANING AIR FILTER
See Figures 37 - 38.
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 Reinstall the filter.
n 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:
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 Champion RCJ-6Y with .025 in. electrode
gap. Use an exact replacement and replace annually.
STORAGE (1 MONTH OR LONGER)
See Figure 39.
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 ISO and local regulations for the safe storage
and handling of gasoline. Excess fuel should be used up

in other 2-cycle engine powered equipment.
�n Always place the sheath on the saw bar when transporting
or storing the pruner. The sheath is a snug fit and must
be attached very carefully due to the sharp teeth on the
saw chain. This is best done by grasping the sheath at
one end, in the center portion of the sheath, and carefully
sliding it over the chain as shown below. Use caution to
avoid the sharp teeth of the chain.
