10-Hour Maintenance
(more frequently in dusty
conditions)
1. Remove the air cleaner cover by loosening
the two thumbscrews. See Figure 16A.
. Remove and inspect the pre-filter. If the
pre-filter is torn or otherwise damaged,
replace it with a new one. See Figure 16B.
3. Clean the pre-filter with soap and water.
Let dry before reinstalling.
4. Inspect the air cleaner element. If the
element is damaged or distorted, re-
place it with a new one.
5. Tap filter gently on a hard surface to
dislodge debris from element or use
compressed air from the inside to blow
debris out and away from the air filter
element.

n Remove and clean the spark plug. Adjust
the spark plug electrode gap to 0.6 - 0.7
mm. If the spark plug must be replaced,
use only an NGK CMR5H or equivalent
resistor type spark plug of the correct
heat range. See Figure 17.
NOTE:
The NGK CMR5H also meets the require-
ments for electro magnetic compliance (EMC).
CAUTION!
Before removing the spark plug, clean
the area around the plug to prevent
dirt and debris from getting into the
engine's internal parts.
