5.5 Telescopic chassis
The distance between the tracks of the telescopic chassis must be completed before the work. Changing the distance between the
tracks during the work may cause great damage to the machine.
Use the bulldozer pilot plus its own button switch combination to control the action of the telescopic chassis cylinder.
When changing the distance between the tracks of the telescopic chassis, the bulldozer and the working device shall be used to lift
the machine off the ground; Then pull out the limit pin, operate the hydraulic cylinder to control the track to stretch to the
corresponding position, and finally install the limit pin and tighten it.
See the following figure:
Figure 1; Left and right telescoping
Figure 2: lift the machine off the ground with working device and bulldozer

nuts with same or higher grade.
