MACHINE OPERATION
SY60C Excavator OMM
Operating on Soft Ground
NOTICE!
• Rugged terrain could cause damage to track
components.
• Wide tracks are intended for operation on soft
ground.
• Inspect the tracks on a regular basis.
Choose the proper tracks 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.
The machine may get stuck when operating on soft
ground. If the machine gets stuck, see “Removing a
Stuck Machine” on this page.
Removing a Stuck Machine

Figure 4-61
Be careful when operating on soft terrain to avoid
becoming stuck. If your machine becomes stuck, perform
the following procedures to free the machine:
WARNING
Use caution when placing cribbing under the
track. The machine is supported only by the boom
and could drop without warning. Failure to follow
this warning could result in death or injury.
One Track Stuck
1.
Position the boom and arm at an angle (1) between
90° and 110°.
2.
Pivot the upper structure to position the boom over
the track that is stuck.
3.
Curl the bucket so the back of the bucket touches the
ground.
4.
Lower the boom to raise the track.
WARNING
Rotating tracks are dangerous. Stay away from
rotating tracks. Failure to follow this warning
could result in death or serious injury.
5.
Remove mud buildup by operating the lifted track
forward and backward.
6.
Place cribbing under the track to provide a firm
surface if necessary.
7.
Raise the boom to lower the track onto the cribbing.
8.
Drive the machine out of the mud.
Two Tracks Stuck
1.
Position the boom and arm at an angle between
90°and 110°.
2.
Pivot the upper structure to position the boom over
the front of the machine.
3.
Curl the bucket so the back of the bucket touches the
ground.
4.
Lower the boom to raise the front of the tracks.
5.
Place cribbing under the tracks to provide a firm
surface if necessary.
6.
Raise the boom to lower the tracks onto the cribbing.
7.
Cut the bucket into the ground in front of the
machine. Retract the arm (as with normal
excavating) while driving the machine forward out of
the mud.
If the machine does not move, tow the machine. See
“Towing the Machine” on page 4-26.
If the machine is not operational, it may need to be
moved using a lifting device. See “Lifting the Machine” on
page 4-36.
Towing the Machine
WARNING
• Make sure the equipment used for towing the
machine has the correct capacity rating.
• Never use a broken chain, worn wire rope, or
bent hook to tow the machine.
• Never jerk the wire rope.
Failure to follow these warnings could result in
death or injury.
