MOVING THE MACHINE

Emergency Stopping

When the Engine has Stalled During Operation:

Pressurized oil in the accumulator acts on the brake
when the brake pedal is depressed. Immediately park
and stop the machine in a safe location. At this time, do
not repeatedly apply the brake pedal.
The brake oil pressure will be quickly reduced so that the
brakes become inoperable.
If the machine does not stop even if the brake pedal is
applied, press the parking brake switch ON side to stop
the machine.
The steering wheel will become hard to rotate as the
hydraulic system becomes inoperable.
In the event any above mentioned symptom occurs,
immediately trace the cause of the problem.
In case a complicate failure has occurred, consult your
nearest authorized dealer.
