Fuel And Chain Oil
Warning: Gasoline is very flammable. Avoid smoking or bringing any flame or sparks near fuel.
Wipe up all spills before starting the engine.
Make sure to stop the engine and allow it cool before starting the engine.
Keep open flames away from the area where fuel is handled or stored.
Important: Never use oil for 4 cycle engine use or water cooled 2-cycle engine.
Never use “FUEL WITH NO OIL (RAW GASOLINE)”.
Never use fuel laced with water.
Mixed fuel which have been left unused for period of one month or more may clog the carburettor or result in the engine
failing to operate properly. Put remained fuel into an air-tight container and keep it in the dark and cool room.
Please ask for “mixed gasoline for air-cooled 2-cycle engines” at your nearest gas station, or use fuel made by putting unlead-
ed 95 octane gasoline and air-cooled 2-cycle special engine oil into a mixing container in accordance with the following ratios
and then shaking to mix well.
Mixing ratios:
Use a special type 2-cycle oil (30ml of oil for each 1L of unleaded gasoline 95).
Chain oil lube
Use an appropriate chainsaw chain lube.
Note: Do not use wasted or regenerated oil that can cause damage to the oil pump.

Warning: Do not start the engine while hanging the chain saw with a hand. The saw chain may touch your body. It is very
dangerous.
