CAUTION
Coolant is poisonous to humans and animals and
is hazardous to the environment. Drain coolant into
an approved container. Dispose of used coolant in
accordance with local laws.
WARNING
Avoid Personal Injury!
Wear personal protective equipment to protect eyes
and hands when opening the radiator cap to protect
against the pressure in the radiator.
If coolant is spilled on skin or clothing, change
clothing and wash affected skin immediately.
WARNING
Avoid Personal Injury!
If the unit has been running, the radiator and radiator
coolant will be hot and can burn skin! Built-up
pressure in the radiator can cause an explosive
release of coolant if the radiator cap is removed:
•
Shut off the engine and allow to cool.
• Do not remove the radiator cap unless the
radiator and engine are cool enough to touch
with bare hands.
•
Slowly loosen the cap to the first stop to release
all of the pressure before removing completely.

Attention
Avoid damage to your engine!
Using the incorrect coolant mixture and/or type can
cause engine damage. Use only a mixture of 50%
distilled water and 50% ethylene glycol antifreeze.
Recommended antifreeze: a low silicate, phosphate
free antifreeze (ethylene glycol) containing supple-
mental coolant additives (SCA’s) to inhibit corrosion
and rust.
Dye Color does not determine the antifreeze proper-
ties: ethylene glycol antifreeze of different colors can
be mixed.
Park the power unit on a level surface.

Engage the parking brake and shut off the
engine.

allow the engine to cool.
