Cooling System Safety
CAUTION
Discharge of hot, pressurized coolant or touching a
hot radiator and surrounding parts can cause severe
burns.
•
Do not remove the radiator cap when the engine
is hot. Always allow the engine to cool at least 15
minutes or until the radiator cap is cool enough
to touch without burning your hand before
removing the radiator cap.
•
Do not touch the radiator and surrounding parts
that are hot.
DANGER
Swallowing engine coolant can cause poisoning.
•
Do not swallow engine coolant.
•
Keep out of reach from children and pets.
Checking the Cooling System
Service Interval:
Before each use or daily
Check the coolant level at the beginning of each day. The
capacity of the system is 8.5 L (9 US qt).
1.
Carefully remove the radiator cap and expansion-tank
cap (
2.
Check the coolant level in the radiator.
Note:
The radiator should be filled to the top of the
filler neck and the expansion tank filled to the Full
mark.

3.
If the coolant is low, add a 50/50 mixture of water and
ethylene glycol anti-freeze.
Important:
Do not use water only or
alcohol/methanol base coolants, as this may cause
damage.
4.
Install the radiator cap and expansion-tank cap.
Servicing the Engine-Cooling
System
Service Interval:
Every 100 hours
Every 2 years
This machine is equipped with a hydraulically driven fan-drive
system that automatically (or manually) reverses to reduce
the radiator/oil cooler and screen debris buildup. While this
feature can help reduce the time required to clean radiator/oil
cooler, it does not eliminate the need for routine cleaning.
Periodic cleaning and inspection of the radiator/oil cooler is
still required.
1.
Shut off the engine and raise the hood.
2.
Clean the engine area thoroughly of all debris.
3.
Clean both sides of the radiator/oil cooler area
thoroughly with compressed air (
).
Note:
Start from the fan side and blow the debris out
toward the back. Then, clean from the back side and
blow toward the front. Repeat this procedure several
times until all chaff and debris is removed.
Important:
Cleaning the radiator/oil cooler
with water can promote premature corrosion and
damage to components.
