Do not try to upgrade the equipment's performance by unapproved modifications.

7. Equipment inspection

Inspect the machine and attachment daily by walking around it before you start it.

Do not operate equipment which is defective or has missing parts.

Make sure the maintenance procedures in this manual are completed before using the equipment.

8. Practice

You and others can be killed or injured if you do unfamiliar operations without practicing them first. Practice away from job site, on a clear area.

Keep other people away.

Do not perform new operations until you are sure you can do them safely.

9. Communications

If you will be working with other people make sure that everyone understands the work-site hand signals and who gives them. Accept signals from one person only.

Work sites can be noisy. Do not rely on spoken commands.

10. Work site

Work sites can be hazardous. Inspect the site before working on it.

Make sure the work site footing has sufficient strength to firmly support the machine. Check for potholes, hidden rocks etc.

Check for utilities (electric cables, gas and water pipes etc.) before digging.

When operating on a slope, keep the load close to the ground.

11. Banks and trenches

Banked material and trenches can collapse. Do not work too close to banks and trenches where there is danger of collapse.

12. Metal splinters

Fine jets of hydraulic fluid at high pressure can penetrate the skin.

Keep hands and body away from pinholes and nozzles which eject fluid under high pressure. Use a piece of cardboard to search for leaks. Do not use your fingers to check for hydraulic fluid leaks.

If ANY fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with this type of injury or gangrene may result.

19. Lines, Tubes and Hoses

Do not bend or strike high pressure lines. Do not install bent or damaged hoses.

Check hoses carefully. Replace if any of the following conditions are found.

* End fittings damaged or leaking.
* Outer covering chafed or cut and wire reinforcing exposed.
* Outer covering ballooning locally.
* Evidence of kinks or crushes in the flexible part of the hose.
* Armoring embedded in the outer cover.
* End fittings displaced.

Make sure that all clamps and shields are installed correctly to prevent vibration and rubbing against other parts during operation.

20. Pressures

Relieve all pressures in air, water or oil systems before any lines, fittings or related items are disconnected or removed. Hydraulic fluid at system pressure can injure you.

Before disconnecting or connecting hydraulic hoses, stop the engine and operate the controls to release pressure trapped in the hoses.
