WARNING When the cab is swung around so that it is facing the track motor end of the undercarriage, the
operation of the track controls is reversed. Take extra care!
The track controls operate as described when the excavator is positioned with the track idlers at the front. If
the excavator is positioned with the track idlers at the rear the lever operation will be reversed. Always travel
the machine with the track idlers positioned at the front, especially on hard and rocky ground to reduce track/
undercarriage wear. Ensure you have complete field of vision when driving the machine.
To move the machine forward, push both levers forward. Release the levers to stop. Track motor braking occurs
automatically when the levers are released.
To move the machine backward, pull both levers backward. Release the levers to stop. Track motor braking
occurs automatically when the levers are released.

A Forward travel B Backward travel
To turn the machine while you travel, move the lever back towards the central position on the side towards
which direction you want to go, for example, move the left lever back to turn left. This causes one of the tracks
to move slower than the other. The faster moving track will push the machine around. Release the lever to stop.

To spin the machine around through 360°, without moving it, operate one lever, in a forward position and the
other in a reverse position. This will cause the tracks to drive in opposite directions and hence push the machine
around.
