Operation on Soft Ground
Choose the proper track when operating the machine on soft ground. Soft ground may cave in and cause the
machine to roll over. Place steel plates on soft ground to support the machine.
Mud buildup on the tracks can be removed using the following steps:
1. Swing the upper structure to position the boom over one track.
2. Curl the bucket so the back of the bucket touches the ground.
3. Lower the boom to lift the stuck track off the ground. Keep the boom-arm angle between 90° and 110° (1) with
the back of the bucket on the ground.
4. Remove mud buildup by rotating the lifted track backward and forward.
5. Raise the boom to lower the track to the ground.
Removing a Stuck Machine
Be careful when operating on soft terrain to avoid becoming stuck. If your machine becomes stuck in soft terrain,
perform the following procedures to free the machine:
One Track Stuck
NOTICE!
•
Rugged terrain could cause damage to track components.
•
Wide tracks are intended for operation on soft surfaces.
•
Inspect the tracks on a regular basis.
WARNING!
•
Rotating tracks are dangerous. Stay away from rotating tracks.
•
Use caution when placing cribbing under the track. The machine is supported only by the
boom and could drop without warning.
Failure to follow these warnings could result in death or serious injury.
