MAINTENANCE

Regular maintenance can prevent problems and damage to equipment. This chapter contains
safety guidelines, maintenance procedures and the recommended maintenance schedule for
your wrecker.

NOTE: See the winch manufacturer manual for more details about winch maintenance.

4.1

Safety guidelines

When performing maintenance on the wrecker, underlift, boom or winches, always:

l

Ensure that you fully understand all the safety rules described in Chapter

2 Safety

.

l

Wear protective clothing (goggles, gloves, footwear, etc.)

l

Watch out for moving parts.

l

Watch out for hot components.

l

When working under the vehicle, apply the parking brake and use wheel chocks.

l

When lifting the vehicle, use approved and certified equipment that is in good condition.

For winch safety guidelines, see the winch manufacturer manual.
