Checking the spark plug

– Only use the supplied universal wrench to remove or to install the spark

plug.

– The gap between the two electrodes of the spark plug should be 0.6 - 0.7

mm (0.024" - 0.028"). If the gap is too wide or too narrow, adjust it. If the

spark plug is clogged with carbon or fouled, clean it thoroughly or replace it.

CAUTION: Never touch the spark plug connector while the engine is running

(danger of high voltage electric shock).

Supply of grease to gear case

– Supply grease (Shell Alvania 3 or equivalent) to the gear case through the

grease hole every 30 hours. (Genuine DOLMAR grease may be purchased

from your DOLMAR dealer.)

Suction head in the fuel tank

– The felt filler (1) of the suction head is used to filler the fuel required by the

carburetor.

– A periodical visual inspection of the felt filter is to be conducted. For that

purpose open the tank cap, use a wire hook and pull out the suction head

through the tank opening. Filters found to have hardened, been polluted or

clogged up are to be replaced.

– Insufficient fuel supply can result in the admissible maximum speed being

exceeded. It is therefore important to replace the felt filter at least quarterly

to ensure satisfactory fuel supply to the carburetor.

Cleaning of muffler exhaust port

– Check of muffler exhaust port (2) regularly.

– If it is clogged by carbon deposits, carefully scratch the deposits out with a

suitable tool.
