Inspect the engine air precleaner for dirt and for trash.
Unscrew T-bolt (1) in order to remove the integrated precleaner body (2) completely.
Use pressurized air to clean the tubes. Put the tubes on a flat surface. Direct the pressurized air into the tubes from the top. This action loosens up the dirt.
Loosen hard deposits of dust on the precleaner body by soaking in an appropriate cleaning agent. Then, wash the precleaner body with a spray of water.
Blow dry the precleaner body completely.
Install precleaner body (2) into the engine air precleaner. Latch the precleaner body in place.
Install T-bolt (1). Hand tighten the T-bolt only.
Close the left engine access door.
Service the air cleaner only with the engine stopped. Engine damage could result.
