Clean the Tracks
! WARNING
If two people are doing this job make sure that the
person working 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
you both understand what the other will be doing.
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 rotating parts.
Keep people not involved with the job well away!

1 Prepare the Machine
Park the machine on level ground. Set the offset-
boom (if fitted) to its central position.
Open the bucket and swing the boom until it is at 90°
to the track. Lower the bucket to the ground.
2 Raise the Track
Operate the boom and dipper controls so that the
track on the side nearest the bucket is lifted up clear
of the ground.
3 Rotate the track
! WARNING
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.
8-3-3-2
When it is safe to do so and you are sure that
everyone is clear of the machine, operate the controls
to rotate the track which is off the ground. Rotate it
first one way and then the other to shake off the mud.
4 Inspect the Track
Set the Servo Isolator Switch to OFF. Stop the
engine. Inspect the track rollers, sprockets and idler
wheels for damage and oil leaks.
5 Lower the Track
Operate the boom and dipper controls to lower the
track to the ground.
6 Repeat for the Opposite Track
Swing the boom round to the other side and repeat
steps 2 to 5 inclusive for the other track.
