8. Maintenance

• REPLACEMENT PLUG IS NGK

• 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.

(9.8~13.7 N.m.)

INTAKE AIR COOLING VENT

• Never touch the cylinder, muffler, or

spark plugs with your bare hands
immediately after stopping the
engine. The engine can become very
hot when in operation, and doing so
could result in severe burns.

• Clean the cylinder fins with

compressed air or a brush. (MA4)

WARNING

IMPORTANT

• Make sure that the engine has

stopped and is cool before
performing any service to the
machine. Contact with moving
cutting head or hot muffler may
result in a personal injury.

AIR FILTER
• The air filter, if clogged, will reduce the

engine performance. Check and clean
the filter element. If the element is
broken or clogged, replace with a new
one. (MA1)

FUEL FILTER
• When the engine runs short of fuel

supply, check the fuel cap and the fuel
filter for blockage. (MA2)

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. (MA3)
