Maintenance

Remove the spark plug caps from the
spark plugs.
2.
Remove the spark plug. If electrode ero-
sion becomes excessive, or if carbon
and other deposits are excessive, you
should replace the spark plug with an-
other of the correct type. WARNING!
When removing or installing a spark
plug, be careful not to damage the in-
sulator. A damaged insulator could
allow external sparks, which could
lead to explosion or fire.
Standard spark plug:

Be sure to use the specified spark plug,
otherwise the engine may not operate
properly. Before fitting the spark plug,
measure the electrode gap with a wire
thickness gauge; replace it if out of spec-
ification.

TIP:
If a torque-wrench is not available when you
are fitting a spark plug, a good estimate of
the correct torque is 1/4 to 1/2 a turn past fin-
ger-tight. Have the spark plug adjusted to the
correct torque as soon as possible with a
torque-wrench.
