Remove the gearcase cover, and use
solvent and a soft brush to remove
all old grease from the gearcase. To
refill, hand-pack the gearcase with ap-
proximately 40–50 grams of high quality
lithium-based grease (50–70% of capac-

NOTE:
The NGK CMR5H also meets the requirements for electro magnetic compliance (EMC).
CAUTION!
Performing a valve adjustment incorrectly may cause hard starting and/or can damage the unit. Refer to the Service
■
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 servic-
■
ing dealer.
Combustion chamber should be decar
■
bonized, and the valve clearance should be adjusted. It is highly recommended
that this is done by a Shindaiwa-trained service technician.
Replace the spark plug annually: Use only NGK CMR5H or equivalent resistor type spark plug of the correct heat range.
■
Set spark plug electrode gap to 0.6 mm.
