HANDLE FLUIDS SAFELY

－

AVOID FIRES

•

Handle fuel with care; it is highly flammable. If fuel
ignites, an explosion and/or a fire may occur,
possibly resulting in serious injury or death.

•

Do not refuel the machine while smoking or when
near open flame or sparks.

•

Always stop the engine before refueling the
machine.

•

Fill the fuel tank outdoors.

•

All fuels, most lubricants, and some coolants are
flammable.

•

Store flammable fluids well away from fire
hazards.

•

Do not incinerate or puncture pressurized
containers.

•

Do not store oily rags; they can ignite and burn
spontaneously.

•

Securely tighten the fuel and oil filler cap.
