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 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).

0.6mm-0.7mm (0.024”-0.028”)

Supply of grease to gear case

Grease hole

Supply grease (Shell Alvania 3 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 filler (5) of the suction head is used to filler the fuel required by the carburetor.

A periodical visual inspection of the fuel 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 fuel filter at least quarterly to ensure satisfactory fuel supply to the carburetor.

Cleaning of muffler exhaust port

Check of muffler exhaust port (6) regularly.

If it is clogged by carbon deposits, carefully scratch the deposits out with a suitable tool.

Any maintenance of adjustment work that is not included and described in this manual is only to be performed by Authorized Service Agents.
