Using The Boom - NRC 30CS Operation And Maintenance Manual

3.9

Using the boom

The boom is normally used to lift a load or another vehicle for towing. The boom can be slid
towards the front or rear of the vehicle, allowing you to lift a load. The position and weight of the
load will determine which procedures in this section you will need to use.
Before operating the boom, make sure you understand the principles of operation
(see Section 3.1 Operating principles) and follow the safety guidelines (see Section
3.3 Safety guidelines). Perform all the preliminary steps to ensure that the wrecker
is stable and level (see Sections 3.4 Familiarizing yourself with the equipment and
3.7.1 Stabilizing the wrecker using the jack legs).
3.9.1 Preparing the slider
To allow the boom to move, you first need to unlock the slider using the control panel.
To unlock the slider, you may have to move the slider forward to relieve any pressure on the
locks.
To move the boom forward or backward:
1. Ensure that both rails are well lubricated.
NOTE: Use Teflon grease to lubricate the rails (see Section 4.3 Lubrication).
2. Slide the boom base back and forth a few times over the entire stroke of the slider to
spread the grease evenly.
3.9.2 Sliding the boom
1. Ensure that the slider is unlocked on the touchscreen interface.
2. Push the boom slider lever up or down to slide the boom forward or backward.
