Checking the Cooling System

The cooling system is filled with a 50/50 solution of water
and permanent ethylene glycol anti-freeze. Check the
level of coolant at the beginning of each day, before
starting the engine.
Warning
If the engine has been running, the coolant in the
radiator will be hot and pressurized. If you
remove the cap, it may spray out, causing severe
burns.
Do not remove the radiator cap to check
coolant levels.
Do not remove the radiator cap when the
engine is hot. Allow the engine to cool for at
least 15 minutes or until the radiator cap is cool
enough to touch without burning your hand.
1. Park the traction unit on a level surface, lower the
loader arms, and stop the engine. Remove the key.

Removing Debris from the
Traction Unit
Important
Operating the engine with a blocked
radiator, may result in engine damage from overheating.
1. Park the traction unit on a level surface, raise the
loader arms, and install the cylinder locks; refer to
Using the Cylinder Locks, page 19.
2. Stop the engine and remove the key.
3. Remove the front access cover, refer to Removing the
Front Access Cover, page 23.
4. Clean any debris from the grill.
5. Open the rear access cover; refer to Opening the Rear
Access Cover, page 23.
6. Wipe away debris from the air cleaner.
7. Clean any debris build-up on the engine with a brush
or blower before each use.
Important
It is preferable to blow dirt out, rather than
washing it out. If water is used, keep it away from
electrical items and hydraulic valves. Do not use a
high-pressure washer. High-pressure washing can damage
the electrical system and hydraulic valves or deplete
grease.
8. Replace and secure the front and rear access covers.
9. Remove and store the cylinder locks (refer to Using
the Cylinder Locks, page 19), and lower the loader
arms.
