INTRODUCTION

Safety rules

Unless otherwise instructed, always perform these steps before you service the machine:

1. Park the machine on a flat, level surface.

2. Place the backhoe in the transport position with the swing lock pin installed for transport.

3. Place the loader bucket on the ground, with the bottom of the loader bucket parallel to the surface.

4. Place the direction control lever and the transmission in neutral.

5. If you need to open the hood to perform service, raise the loader arms and install the support strut.

6. Shut down the engine.

7. Place a 'Do Not Operate' tag on the key switch so that it is visible to other workers or remove the key.
