Retrieval
Notice: It is not recommended to tow a disabled machine. Permanent damage to the track motors of the
disabled machine may occur if the machine is towed.
In the event that towing the machine to a safe location is unavoidable then attach wire rope or chain capable
of pulling the machine around the slew ring as shown. Refer to Figure 67.
Notice: Do not use the tow eye or tie down points (if installed) to tow the machine, as this will cause damage
to the machine.
Apply the minimum force to move the machine slowly (not greater than 2km/h (1.2mph) smoothly and without
shocks).
Tow the machine the minimum distance to a safe location for recovery by lifting (not to exceed 20m). Following
this procedure the machine must be inspected by a qualified person for damage to the track motors.
Figure 67.
Excavator Arm (Emergency Operation)
The excavator has an accumulator installed. The accumulator stores a limited amount of hydraulic pressure
for use in an emergency (engine failure for example). This hydraulic pressure must be used to move the dipper
and lower the boom into a safe position.
Do not try to operate other machine functions as this will deplete the hydraulic pressure in the accumulator and
it may then not be possible to move the dipper and lower the boom.
If an emergency occurs:
1. Turn the ignition key to the on position.
2. Enable the controls.
Refer to: Control Lock (Page 49).
