6. Clean any debris build-up on the engine and in the oil
cooler fins with a brush or blower.
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.
7. Clean debris from the cooler fan grill on the hood.
8. Close the hood.

Checking the Hydraulic Fluid

Check the hydraulic fluid level before the engine is first
started and after every 25 operating hours.
Hydraulic Tank Capacity: 12 US gallons (45.4 l)
Use 10W-30 detergent, diesel engine oil (API service
CH-4 or higher).
1. Remove the attachment, if one is installed; refer to
Removing an Attachment, page 22.
2. Park the traction unit on a level surface, lower the
loader arms, and fully retract the tilt cylinder.
3. Stop the engine, remove the key, and allow the engine
to cool.
4. Open the hood; refer to Opening the Hood, page 24.
5. Clean the area around the filler neck of the hydraulic
tank (Fig. 4).

fluid level on the dipstick (Fig. 4).
The fluid level should be between the marks on the
dipstick.
