q
Never use the machine for operations with the track frame retracted.
q
Never operate the cylinders suddenly when extending or retracting the track frame gauge width. It is
dangerous if they are operated suddenly.
q
Stop the machine on firm level ground when extending or retracting the track frame gauge width.
Reducing Track Gauge
1. Remove center frame mounting bolts (1) (front and rear: 9
each) on one side.
2. Swing the upper structure to the side where the track frame
gauge is to be reduced, set it at 90° to track frame (2), then
use the work equipment to jack up the track frame.
3. Set blocks (3) (20 to 30 cm wooden blocks) towards the
outside of track frame (2), then use the boom cylinder to
lower the machine slowly. The track frame (2) will slide and
stop when it contacts the stopper.
4. Lower the machine slowly to the ground, then install 8 of
removed mounting bolts (front and rear: 4 each).
