General
WARNING
Do not raise the engine hood or cab if
you see or hear steam or coolant escap-
ing from the engine compartment. Wait
until steam or coolant cannot be seen or
heard before raising the hood or cab.
Do not remove the coolant fill cap if the
coolant in the surge tank is boiling.
Also, do not remove the cap while the
engine and radiator are still hot. Scalding
fluid and steam may be blown out under
pressure if the cap is taken off too soon.

Many engine failures can be traced back to
a problem in the cooling system. Always
make sure that the coolant level is above
the min. mark on the surge tank. If the
coolant level is allowed to go below the
bottom of the tank, there is the risk of the
engine shutting down. See the Operator’s
Manual for more information on the warn-
ing functions. See page 122 or page 124 for
information on how to change the coolant.
Coolant is toxic; risk of poisoning. Do
not drink coolant. Use proper hand pro-
tection when handling. Keep coolant out
of reach of children and animals. Failure
to follow these precautions can cause se-
rious illness or death.
NOTE! Always dispose of coolant accord-
ing to Federal or local regulations. Take all
used coolant to a recycling or waste collec-
tion center.
