Height H of the track frame being raised should be less than 50
mm (2 in). Take care not to raise the track frame so much that the
stopper bolt is distorted.
Pull the machine forward with the arm, and the track frame will
slide sideways.

Extend the track frame until it comes into contact with the
stopper, then lower the machine slowly to the ground. Install
bolts @ (one side, front + rear: 22) and tighten to specified
torque.

(280 ? 30 kgm, 2025 f 220 Ibft)
Follow the same procedure to extend the track frame on the

The track gauge should be changed on level, hard ground.
When changing the track gauge, it is dangerous to operate any
