AIR-INTAKE SYSTEM

Wear fall arresters.

Risk of injury caused by rotating or hot parts of the engine. Shut off the engines before working on the air-intake system.

Secure the machine as described in the "Securing the machine" section. Read and observe the "Engine - Safety instructions" chapter.

Do not start the engine when parts of the air-intake system have been detached.

Engine damage may occur if the engine is allowed to draw in unfiltered air.

Each engine is equipped with two dry-air filters (Fig. 3-46:) consisting of main and safety filter element.

Insufficient air-intake performance, caused by a contaminated main filter element, is displayed on the BCS-screen (Fig. 3-47:).

Clean or renew main filter elements only if the BCS displays a warning on the screen (Fig. 3-47:) with the engines running at high speed.
