Important: Operating the engine with blocked screens and/or cooling shrouds removed, will result in engine damage from overheating.
-
Park the machine on a level surface, lower any attachments, and shut off the engine.
-
Remove the key and allow the engine to cool.
-
Open the hood.
-
Clean any debris from the front and side screens.
-
Wipe away any debris from the air cleaner.
-
Clean any debris build-up on the engine and in the oil cooler fins with compressed air.
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.

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 2 to 5 cm (1 to 2 inches) deep, have an Authorized Service Dealer remove the rear of the machine, fuel tank, and battery and flush the chassis clean.
