MAINTENANCE AND STORAGE
Freezing
DEF will freeze around 12° F (-11° C). The
DEF system on the machine is designed to
accommodate this and does not require any
operator intervention.
DEF Disposal
Check with local authority regulations on
proper DEF disposal requirements.
Cooling System
The cooling system should be sufficiently
charged with an adequate mixture of
antifreeze and water, regardless of climate,
to maintain broad operating temperature
range. Follow the coolant manufacturer’s
recommendations for your climate.
NOTE: The cooling system has been
factory-filled with an ethylene glycol-
based antifreeze.

Coolant
Checking Coolant Level/
Concentration
Check coolant level daily. Ensure the
Surge Tank has adequate fluid level before
operating. The Surge Tank is transparent
and fluid volume is determined by the molded
markings on the outside of the tank.
A 50/50 ethylene glycol and water mixture
is a conservative mixture, which allows
protection against both overheating and
freezing.
CAUTION
DO NOT add any chemicals/additives to
the DEF in an effort to prevent freezing.
If chemicals/additives are added to the
DEF, the Aftertreatment System may
become damaged.
NOTICE
Do not use coolants that contain nitrite
additives.
