WARNING
CAUTION
1. Remove engine cover, rocker arm cover, and set piston at
TDC-compression.
2. Loosen adjuster locknut so that the 2.5 mm Allen socked
head adjustment screw can turn freely.
Performing a valve adjustment incorrectly may cause hard
starting and/or can damage the unit. Refer to the C-4 Serv-
ice Manual for complete valve adjustment procedure and
torque specifications.
If you are unfamiliar with this engine or uncomfortable with
this procedure, consult with an authorized shindaiwa serv-
icing dealer.
3. Insert 0.10 mm feeler gauge between valve stem tip and
rocker arm.
4. Turn adjustment screw (clockwise = tighter, anticlockwise =
looser) until feeler gauge is almost snug. Back off just
enough to allow gauge to slip out with limited resistance.
5. While holding adjustment screw in place with Allen driver,
tighten locknut with wrench.
6. Turn engine over several times, and return to TDC-compres-
sion. Recheck with proper feeler gauge to make sure clear-
ance adjustment did not change as a result of tightening
locknut. Readjust as necessary.
7. Replace rocker arm cover gasket to assure proper sealing
and install cover.
IMPORTANT
If new gasket is not available and/or old gasket is not damaged,
old gasket may be reused. Never use cracked or damaged gas-
kets.
