Cooling System Safety
•
Swallowing engine coolant can cause poisoning;
keep out of reach from children and pets.
•
Discharge of hot, pressurized coolant or touching
a hot radiator and surrounding parts can cause
severe burns.
– Always allow the engine to cool at least 15
minutes before removing the radiator cap.
– Use a rag when opening the radiator cap, and
open the cap slowly to allow steam to escape.
Servicing the Cooling
System
Service Interval: Before each use or daily—Clean
the screen, oil cooler, and front of
the radiator (more often in dirty or
dusty conditions).
Before each use or daily—Check the coolant
level in the expansion tank.
Every 100 hours—Check the cooling system
hoses.
Yearly—Change the engine coolant (Authorized
Service Dealer only).
Cleaning the Radiator Screen
Service Interval: Before each use or daily
Remove any buildup of grass, dirt or other debris from
the radiator screen with compressed air.
Checking the Engine-Coolant
Level
The cooling system is filled with a 50/50 solution of
water and permanent ethylene-glycol antifreeze.
1.
Park the machine on a level surface, lower the
loader arms, engage the parking brake, and
shut off the engine.
2.
Remove the key from the key switch and allow
the engine to cool.
3.
Check the coolant level in the expansion tank
(Figure

The coolant level should be at or above the mark
on the side of the tank.
1. Expansion tank

If the coolant level is low, remove the expansion
tank cap and add a 50/50 mixture of water and
permanent ethylene-glycol antifreeze.
Important:
Do not overfill the expansion
tank.
5.
Install the expansion-tank cap.
