Servicing The Cooling System
WARNING
Avoid Personal Injury!
If the unit has been running, the radiator and radia-
tor 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 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 cap to the fi rst stop to release
all the pressure before removing completely.
WARNING
Avoid Personal Injury!
Wear personal protective equipment to protect
eyes and hands when opening 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.
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.
Attention
Avoid damage to your engine!
Using incorrect coolant mixture and/or type can
cause engine damage. See the Engine Owner’s
Manual for correct type.
• Do not operate engine without coolant.
• Do not use plain water only, you must use a
mixture of water and antifreeze.
• Do not pour coolant into radiator when engine
is hot.
• To prevent engine overheating, do not exceed
more then 50% antifreeze in cooling system.
