B-5
Test the Emergency Stop
Genie requires that this procedure be performed
every 250 hours or quarterly, whichever comes
first.
A properly functioning Emergency Stop button 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.
Note: The red Emergency Stop button at the
ground controls will stop all machine operation,
even if the key is switched to platform control.
Note: If in ground controls mode and the red
Emergency Stop button at the platform controls is
pushed in, the ground controls LCD will display,
Platform EStop Depressed. The machine alarm will
sound at 1 beep per second.
B-6
Test the Key Switch
Genie requires that this procedure be performed
every 250 hours or quarterly, whichever comes

Proper key switch action and response is essential

operated from the ground or platform controls and
the activation of one or the other is accomplished

activate the appropriate control panel could cause
a hazardous operating situation.
Note: 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.

ground controls.

operate.
4 Turn the key switch to ground control.

platform controls.
Result: The machine functions should not
operate.
6 Turn the key switch to the off position.
