Cleaning the air cleaner (filter)
– Unscrew screw (1).
– Turn the choke lever (4) to the fully closed side, and keep the carburetor away
from any dust or dirt.
– Remove the air cleaner cover (3).
– Remove the sponge element (2), wash it in lukewarm water and dry it
completely.
– After cleaning, put back the air cleaner cover (3) and fasten it with screw (1).
NOTE: If there is excessive dust or dirt adhering to the air cleaner, clean it every
day. A clogged air cleaner may make it difficult or impossible to start the
engine, or may increase the engine rotational speed.
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 0.6-0.7mm
(0.024"-0.028"). If the gap is too wide or too narrow, adjust it. If the spark plug
is clogged with carton or dirty, 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 fuel filler (5) of the suction head is used to supply the fuel required by the
carburetor.
– Visually inspect the fuel filter periodically. To inspect the filter, open the tank
cap, use a wire hook and pull out the suction head through the tank opening.
Replace the filter if it has hardened, become particularly dirty, or clogged.
– Insufficient fuel supply may result in the maximum permissible speed being
exceeded. Therefore, the fuel filter must be replaced at least quarterly to
ensure satisfactory fuel supply to the carburetor.
Any other maintenance or adjustment work that is not described in this manual must only be performed by Authorized Service Agents.
