PREPARING FOR OPERATION
Fuel and oil mixture
Inspect the fuel tank and fill with clean, fresh fuel of the proper mixture to assure the longer life of the tool. Use
the following mixed gas.
Gasoline : Makita genuine Two-stroke engine oil = 50 : 1 or
Gasoline : Other maker's Two-stroke engine oil = 25 : 1
FOR CALIFORNIA REGULATION:
THIS EQUIPMENT IS CERTIFIED TO OPERATE ON GASOLINE TWO STROKE OIL_
WHEN MIXING GASOLINE WITH TWO STROKE OIL, USE ONLY GASOLINE WHICH CONTAINS NO ETHANOL
OR METHANOL (TYPES OF ALCHOL), THIS WILL HELP TO AVOID POSSIBLE DAMAGE TO ENGINE FUEL
LINES AND OTHER ENGINE PARTS.
DO NOT MIX GASOLINE AND OIL DIRECTLY IN THE FUEL TANK.
IMPORTANT: Failure to follow proper fuel mix instructions may cause damage to the engine.
CAUTION;
1. When preparing fuel mixture, mix only the amount needed for the job you are to do. Do not use fuel mixture
that has been stored longer than two months. Fuel mixture stored longer than this will cause hard starting and
poor performance. If fuel mix has been stored longer than this time, it should be removed and filled with a
fresh mixture.
2. Never fill the fuel tank to the very top.
