WARNING If two people are doing this job make sure that the person operating the controls is a competent

operator. If the wrong control lever is moved, or if the controls are moved violently, the other person could

be killed or injured.

If you will be working with another person, make sure that you both understand what is to be done. Learn

and use the recognised signalling procedures. Do not rely on shouting - he will not hear you.

To clean the tracks, you must turn them. When the tracks are turning, keep clear of rotating parts. Before

starting this job, make sure that you have no loose clothing (cuffs, ties etc.) which could get caught in moving

parts. Keep people not involved with this job well away!

CAUTION Rotating the tracks off the ground may cause stones and other debris to be thrown with

considerable force. If you are on the outside, keep well clear. Keep other people well clear.

1. Stop the machine on solid, level ground.

2. Open the bucket.

Refer to: Operation > Operating Levers/Pedals > Excavator Arm Controls (Page 96).

3. Slew the boom until it is at the specified angle to the track.

4. Lower the bucket to the ground.

5. Operate the controls to push the boom down so that the track nearest the bucket is lifted clear of the ground.

Refer to Figure 232.

6. When it is safe to do so and you are sure that everyone is clear of the machine, operate the controls to

turn the track which is off the ground.

7. Turn the track one way and then the other to shake off the mud. If necessary, the person outside can use

water from a hose to help loosen the sticky material.

8. When the track is clean, stop the movement.

9. Examine the track, roller sprockets and idler wheels for damage or oil leaks. Replace any damaged parts.

If in doubt contact your JCB dealer.

10. Operate the controls slowly to lower the track to the ground.

11. Operate the controls to slew the boom to the other side of the machine, then repeat the steps 2 to 10 and

clean the other track.
