Cleaning
Removing Debris from the
Machine
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. Lower the boom and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Wipe away debris from the air cleaner.
4. Clean any debris build-up on the engine 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.
5. Clean debris from the oil cooler (model 22971 only).
