Check/Add Coolant Level

WARNING
If engine is warm, DO NOT remove radiator cap.
Escaping steam can cause burns.
Never remove the radiator cap or radiator reservoir cap
while the engine is hot or running. Severe thermal burns or
injury can occur by escaping steam or hot coolant.
• Do NOT touch hot radiator or open reservoir when
engine is running.
• Stop and allow engine to cool before removing the
radiator cap or the reservoir cap and before changing or
adding coolant.
The engine coolant level and quality should be checked
before each use when the engine is cool and off.
1. Remove the radiator cap (A, Figure 37) to check the fluid
level.

2. Coolant level should be flush with the bottom of the filler
tube. If coolant level is low, add coolant until the level
is flush with the bottom of the filler tube. Proper coolant
mix is a 50/50 mixture of ethylene glycol and distilled
water. See engine owners manual for engine coolant
specifications.
This unit is equipped with a coolant expansion tank (B). Do
not add coolant through the expansion tank.

Change Engine Coolant

See engine owners manual for specific engine coolant
change procedures. The drain valve is located at the base of
the radiator.
The engine manufacturer recommends that the cooling
system be cleaned and the flushed before the recommended
maintenance interval conditions exist:
• The engine overheats frequently.
• Foaming is observed.
• Fuel and/or oil has entered the cooling system and the
coolant is contaminated.

Clean Radiator, Screen, and Oil Cooler

Clean the radiator, screen, and oil cooler fins before each
use, or as required (depending on conditions) to allow proper
air-flow through radiator and hydraulic oil cooler.
1. Raise the seat plate.
2. Lift the radiator screen (A, Figure 38) straight up to
remove the screen. Flush the screen with water or blow
clean with air. Flush the radiator core with water or blow
clean with air. See engine owner's manual for proper
radiator cleaning procedures.

3. Install the radiator screen. Make sure the screen is fully
seated in the carrier.
4. Clean all dirt, grass, and debris from the oil cooler fins
(B).
5. Lower the seat plate.
Regen Process (Clean Diesel Particulate
Filter)
This unit is equipped with a diesel particulate filter that will
clean itself through a regen process. The digital display panel
will notify the operator when the regen process is required
with a pop up (A, Figure 39) on the screen. The unit will also
prevent the operator from changing the engine RPMs until the
regen process has been run.
