Introduction

This Special Instruction outlines the basic steps that are required to install a new air cleaner and a precleaner.

The new air cleaner provides better protection. The air cleaner is easier to service.

Do not perform any of these procedures until you have read the information in this publication.

Refer to the appropriate Parts Manual, Operation and Maintenance Manual, and Service Manual.

Put the machine in the servicing position.

3. The servicing position is attained by lowering the boom until the bucket is flat on the ground. The stick should be in the vertical position when the bucket is flat on the ground. Refer to Illustration 1.

4. Shut off the engine.

5. Move the control levers for the boom, the stick, the bucket, swing operation, and the left and right travel to the full stroke positions. This movement will release any actuator pressure in the hydraulic lines.

NOTICE
Never remove the fill/vent plug from the hydraulic tank if the oil is hot. Air can enter the system and cause pump damage.

7. Slowly loosen the fill/vent plug on the hydraulic tank in order to relieve the pressure in the tank. Once pressure is relieved tighten the fill/vent plug.

8. Remove the key which starts the machine. Secure the cab.
