MAINTENANCE

Check the Tires and Wheels

Bodily injury hazard. An over- inflated tire can explode and may cause death or serious injury.

Collision hazard. An excessively worn tire can cause poor handling and continued use could result in tire failure.

Tip-over hazard. Do not use temporary flat tire repair products.

Maintaining the tires and wheels in good condition is essential to safe operation and good performance. Tire and/or wheel failure could result in a machine tip-over. Component damage may also result if problems are not discovered and repaired in a timely fashion.

1Check the tire surface and sidewalls for cuts, cracks, punctures and uneven or excessive tread wear.

Result: Replace the tire if uneven or excessive tread wear is found.

Tires and wheels must be replaced with tires and wheels of the specifications listed.

2Check each wheel for damage, bends and cracks.

Result: Replace the wheel if any damage is found.

3Check each tire with an air pressure gauge and add air as needed.

4Check the torque of each lug nut.

Check the Hydraulic Oil Level

Maintaining the hydraulic oil at the proper level is essential to machine operation. Improper hydraulic oil levels can damage hydraulic components. Daily checks allow the inspector to identify changes in oil level that might indicate the presence of hydraulic system problems.

1Be sure the boom is in the stowed position and the outriggers are raised.

2Open the cover on the side of the machine opposite the ground controls.

3Use the marks on the side of the hydraulic tank to determine the level of hydraulic oil.

Result: The hydraulic oil level should be between the ADD and FULL marks.

4 Add hydraulic oil if necessary.
