WARN I N G
Radiator
Coolant Level
Do NOT service cooling system unless engine has
been allowed to cool down. This is a pressurized
cooling system and escaping steam or hot coolant
will cause serious burns.
Do NOT remove cooling system radiator cap when
engine is hot. Allow engine to cool down. Loosen
cap to first stop and let any pressure out of cooling
system, then remove cap. Failure to follow this
warning may result in serious burns.
Wear effective eye, hand,and skin protection when
handling coolants. Failure to do so may result in
injury.
C AU T I ON
Do not add water to pre-mixed antifreeze. If water
is added to pre-mixed antifreeze, it will be diluted
and will not provide proper engine protection and
engine and/or cooling system damage may occur.
Be sure to identify th type of antifreeze being
e
added, or engine and/or cooling system damage
may occur.
N OT E
Some antifreeze is pre-mixed and requires no
water.
Traditional antifreeze requires mixing with an equal
amount of water. Mix antifreeze and water before
adding to machine cooling system to ensure proper
1:1 ratio is used.
It is allowable to mix traditional and pre-mixed anti-
freeze in the same cooling system.
