Cleaning
Removing Debris from the
Traction Unit
Service Interval:
Before each use or daily
Important:
Operating the engine with blocked
screens, dirty or plugged cooling fins, and/or
cooling shrouds removed, will result in engine
damage from overheating.
1. Park the traction unit on a level surface, lower the
loader arms, and stop the engine.
2. Remove the key and allow the engine to cool.
3. Open the hood.
4. Clean any debris from the front and side screens.
5. Wipe away debris from the air cleaner.
6. Clean any debris buildup 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.
Cleaning the Chassis
Service Interval:
Every 100 hours—Check for dirt
build-up in the chassis.
Over time, the chassis under the engine collects dirt
and debris that must be removed. Using a flashlight,
open the hood and inspect the area under the engine on
a regular basis. When the debris is 1 to 2 inches deep,
complete the following procedure (refer to Figure 63
throughout this procedure):
