PROCEDURES
B-3
Test the Emergency Stop
A properly functioning Emergency Stop is essential
for safe machine operation. An improperly
operating red Emergency Stop button will fail to
shut off power and stop all machine functions,
resulting in a hazardous situation.
As a safety feature, selecting
and operating the ground controls
will override the platform controls,
except the platform red
Emergency Stop button.
1 Turn the key switch to ground control and pull
out the red Emergency Stop button to the on
position at both the ground and platform
controls.
2 Push in the red Emergency Stop button at the
ground controls to the off position.
Result: No machine functions should operate.
3 Turn the key switch to platform control and pull
out the red Emergency Stop button to the on
position at both the ground and platform
controls.
4 Push down the red Emergency Stop button at
the platform controls to the off position.
Result: No machine functions should operate.
The red Emergency Stop button at
the ground controls will stop all
machine operation without regard
to the position of the key switch.
B-4
Test the Key Switch
Proper key switch action and response is essential
to safe machine operation. The machine can be
operated from the ground or platform controls and
the activation of one or the other is accomplished
with the key switch. Failure of the key switch to
activate the appropriate control panel could cause
a hazardous operating situation.
Perform this procedure from the
ground using the platform controls.
Do not stand in the platform.
1 Pull out the red Emergency Stop button to the
on position at both the ground and platform
controls.
2 Turn the key switch to platform control.
3 Check the platform up/down function from the
ground controls.
Result: The machine functions should not
operate.
4 Turn the key switch to ground control.
5 Check the machine functions from the platform
controls.
Result: The machine functions should not
operate.
6 Turn the key switch to the off position.
Result: No function should operate.
