higher can damage the filter. Hold the air nozzle inside the filter and
direct the air stream outward to blow the dirt and debris away from the
outer surface.
NOTICE! Do not use compressed air with chemicals to clean the air filter. The

REPLACING THE SPARK PLUG
NOTICE! Using an incorrect spark plug can cause engine damage. Only replace a
spark plug with a model recommended by the manufacturer.
The spark plug must be properly gapped and free of deposits for the best
performance. Check local bylaws to see if a resistor spark plug is required to
suppress ignition signals. Replace the included spark plug with a resistor spark
plug if required.
1.
Remove any dirt from around the spark plug area.
2.
Unclip the spark plug lead and remove the spark plug with a spark plug
wrench. This will have a rubber pad inside the socket to protect the spark
plug’s ceramic coating.
3.
Inspect the spark plug. Replace it if damaged, badly fouled, the sealing
washer is in poor condition or the electrode is worn.
4.
Check the gap with a spark plug gauge as
shown in Figure 9. If necessary, reset the
gap (See Specifications).
a.
Correct the gap by carefully bending
the side electrode. Check the gap after
each adjustment.
5.
Install the spark plug carefully by hand to
avoid cross threading.
6.
Tighten the spark plug to the
recommended torque until the gasket is
compressed. See Specifications for the
correct torque rating.
