POTENTIAL HAZARD
• Gasoline contains gasses that can build up pressure inside a gas tank.
WHAT CAN HAPPEN
• Fuel can be sprayed on you when removing fuel tank cap.
HOW TO AVOID THE HAZARD
• Remove fuel tank cap slowly to avoid injury from fuel spray.
DANGER
POTENTIAL HAZARD
• In certain conditions gasoline is extremely flammable and highly explosive.
WHAT CAN HAPPEN
• A fire or explosion from gasoline can burn you, others, and cause property damage.
HOW TO AVOID THE HAZARD
• Use a funnel and fill the fuel tank outdoors, in an open area, when the engine is cold.

FUEL; MIXING GASOLINE AND OIL
IMPORTANT: The engine used on this Handheld Blower is of a 2-cycle design. The internal mov-
ing parts of the engine, i.e., crankshaft bearings, piston pin bearings and piston to cylinder wall
contact surfaces, require oil mixed with the gasoline for lubrication. Failure to add oil to the gasoline
or failure to mix oil with the gasoline at the appropriate ratio will cause major engine damage which
will void your warranty. For your fuel premix, only use a quality oil designed for 2-cycle air-cooled
engine.
FUEL MIXTURE: Always use a good quality 2-cycle, air-cooled engine oil mixed at a ratio of 25:1.
FUEL MIXTURE CHART:
MIXING INSTRUCTIONS: Always mix fuel and oil in a clean container approved for gasoline.
Mark the container to identify it as fuel mix for the Handheld Blower. Use regular unleaded gasoline
and fill the container with half the required amount of gasoline. Pour the correct amount of oil into
the container then add the remaining amount of gasoline. Close the container tightly and shake it
momentarily to evenly mix the oil and the gasoline before filling the fuel tank on the Handheld
Blower.
When refilling the Handheld Blower fuel tank, clean around the fuel tank cap to prevent dirt and
debris for entering the tank during cap removal. Always shake the premix fuel container momen-
tarily before filling the fuel tank.
Always use a spout or funnel when fueling to reduce fuel spillage. Only fill the tank to within 6 ~ 13
mm (1/4 ~ 1/2 inch) from the top of the tank. Avoid filling to the top of the tank filler neck.
NOTE:
1. Never mix gasoline and oil directly in the Handheld Blower fuel tank.
2. Do not use National Marine Manufacturer’s Association (NMMA) or BIA certified oils. This type
of 2-cycle engine oil does not have the proper additives for air-cooled, 2-cycle engines and can
cause engine damages.
3. Do not use automotive motor oil. This type of oil does not have the proper additives for air-
cooled, 2-cycle engines and can cause engine damage.
