SPARK PLUG

• Starting failure and mis-firing are often caused

by a fouled spark plug. Clean the spark plug and
check that the plug gap is in the correct range.
For a replacement plug, use the correct type
specified by RedMax. (MA5)

• REPLACEMENT PLUG IS A NGK CMR7A.

• Note that using any spark plug 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: 87~104 in-lbs 

(9.8~11.8 N.m.)

MUFFLER

• Inspect periodically, the muffler for loose

fasteners, any damage or corrosion. If any sign
of exhaust leakage is found, stop using the
machine and have it repaired immediately. 

• Note that failing to do so may result in the

engine catching on fire.

SPARK ARRESTER

• The muffler is equipped with a spark arrester to

prevent red hot carbon from flying out of the
exhaust outlet. Periodically inspect and clean as
necessary with a wire brush. In the State of
California it is required by law (Section 4442 of
the California Public Resources Code) to equip a
spark arrester when a gas powered tool is used
in any forest covered, brush covered, or grass
covered unimproved land. (MA6)
