Do not operate or work on this machine unless you have read and understand the instructions and warnings in the Operation and Maintenance Manual. Failure to follow the instructions or heed the warnings could result in injury or death. Contact your Caterpillar dealer for replacement manuals. Proper care is your responsibility.

Escaping fluid under pressure, even a pinhole size leak, can penetrate body tissue, causing serious injury, and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury. Always use a board or cardboard when checking for a leak.

Personal injury can result from rotating and moving parts. Stay clear of all rotating and moving parts. Never attempt adjustments while the machine is moving or the engine is running unless otherwise specified. The machine must be parked on a level surface and the engine stopped. Attach a "Do Not Operate" or similar warning tag to the start switch and controls before servicing, repairing, or making adjustments to the machine.

Personal injury can result from hydraulic oil pressure and hot oil. Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system. Make sure all of the attachments have been lowered, and the oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.

A visual inspection of the hydraulic system and the components of the hydraulic system is the first step when a diagnosis of a problem is made. Stop the engine, and make the following inspections.

1. Measure the oil level in the hydraulic oil tank.

2. Use a clear container to obtain an oil sample from the hydraulic tank immediately after the engine is stopped. Examine the sample for air bubbles.

3. Check all oil lines and check all connections for damage. Look for oil on the ground under the machine.

4. Remove the hydraulic oil filter and examine the filter element for debris.

   1. Shiny steel particles indicate a pump failure or the particles indicate deterioration of the pump. Shiny steel particles can also indicate a failure of the motor or deterioration of the motor.

   2. Rubber particles indicate seal failures or hose failures.

   3. Bronze colored particles indicate failure to the pump or motor piston slippers or these particles could indicate wear of the port plate due to contamination.

   4. Aluminum particles indicate a failure to the vibratory motor.

      Note: When foreign particles are found, flush the system in which the failure occurred. Also, flush the system that supplies charge oil to the system that failed. Each hydraulic system must be filtered independently. Do not reuse damaged parts.

5. Inspect the control linkages for damaged components.

6. Check the machine for loose wiring. Check the machine for frayed wiring.

7. Inspect the lights for broken bulbs. Inspect the lights for broken lenses. Replace the bulbs or the lenses if the bulbs or the lenses are broken.

8. Inspect the following for damage or wear: steps, walkways and handholds. Repair any damaged components or worn components. Inspect these areas for cleanliness. Clean the components.
