Cleaning the Tracks
!MWARNING
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!

1 Prepare the Machine. K Prepare the Machine for
Maintenance ( T 3-29).
Park the machine on level ground. 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.
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.
If necessary, the person outside may use water to get
the mud off.
4 Inspect the Track.
When you have finished, 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.
Cleaning the Radiator and Oil Cooler
A clogged radiator and/or oil cooler can lead to engine
overheating. Regularly check for a build-up of dirt and
debris and if necessary, use compressed air to clean-out
the grille. At the same time check all hoses for damage or
perishing, and replace if necessary.
