ENGINE

SHAFT

■ 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)

• 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.
