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 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 2 or equivalent) to the gear case through the
grease hole every 30 hours. (Genuine MAKITA grease may be purchased
from your MAKITA dealer.)
Suction head in the fuel tank
– The fuel filter (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 fuel
filler 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.
