Throttle Cable Free Play
If the unit does not return to idle speed or
doesen't reach full rpm, the throttle lever
free play may need to be adjusted as follows:
1. Measure free play at the end of the
throttle lever. Throttle lever free play
should be approximately 0.-0.75"
(5-7 mm). See Figure 14.
. If adjustment is necessary, remove the
air cleaner cover by loosening the two
thumbscrews. Loosen the cable adjuster
lock nut and turn the cable adjustment fit-
ting in or out until throttle lever free play
is approximately 0.-0.75" (5-7 mm).
3. Replace the air cleaner cover, and tight-
en the cover retaining screws securely.
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 el-
ement is damaged or distorted, replace
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

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.
