CAUTION:
Never run the engine
without the air cleaner
element installed.
A
defective
air cleaner can result in loss of
engine power and can cause excessive
wear or damage
to the engine components
if dirt or dust is permitted
to enter the
engine through
the carburetor.
A damaged
air cleaner,
or one that is clogged with dust
or dirt should be replaced
immediately.
SPARK PLUG
Clean the spark plug and reset the gap
periodically.
Before removing
spark plug,
clean the area around its base to prevent
dirt from entering
into the engine.
Replace
the spark plug if the electrodes
are pitted or
burned or if the porcelain
is cracked. Clean
the spark plug by carefully
scraping the
electrodes
with a knife or screwdriver
(do
not sand blast or use a wire brush). Be sure
the spark plug is clean and free of foreign
material.
Check the electrodes
gap with a
wire feeler gauge and reset to .030 inches if
necessary.
If a new spark plug is needed,
refer to the PRODUCT
SPECIFICATION
on
page 9 for the proper replacement
spark
plug.
Before reinstalling
the spark plug, coat the
threads lightly with graphite or light oil to
insure easy removal.
Tighten the spark plug
firmly into the engine.
If a torque wrench is
available,
torque the spark plug to 15 foot-
pounds.
CAUTION:
Always stop the engine
and disconnect the spark plug wire before
making any repairs to the Edger/Trimmer.
