AIR FILTER
• The air filter, if clogged, will reduce the
engine performance. Monthly check and clean
the filter element in warm, soapy water as
required. Dry completely before installing. If the
element is broken or shrunk, replace with a new
one.

SPARK PLUG
• Starting failure and mis-firing are often
caused by a fouled spark plug. Periodically clean
the spark plug and check that the spark gap is in
the correct range.
• When you take off the spark plug, twist (1)
and pull off the cap (2).
IMPORTANT
• Note that using any spark plugs other than
those designated may result in the engine failing
to operate properly or in the engine becoming
overheated and damaged.
• To install the spark plug, first turn the plug
until it is finger tight, then tighten it a quarter
turn more with a socket wrench.
TIGHTENING TORQUE: 9.8~11.8 N.m

WARNING
•
Inspect periodically, the muffler for loose
fasteners, any damage or corrosion. If any sign
of exhaust leakage is found, do not use the
brush cutter and have it repaired immediately.
•
Note that failing to do so may result in the
engine catching on fire.
