Test the Emergency Stop

Genie specifications require that this procedure be
performed every 250 hours or quarterly, whichever
comes first.
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.
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.
Note: Rotate the red Emergency Stop button at
platform control one quarter turn in a clockwise
direction to restore the power supply. The red
Emergency Stop button returns automatically to
the out, or on position.
2 Push in the red Emergency Stop button at the
ground controls to the off position.
3 Check the machine functions from the ground
controls.
Result: The machine functions should not
operate.
4 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.
5 Push the red Emergency Stop button at the
platform controls to the off position.
6 Check the machine functions from the platform
controls.
Result: The machine functions should not
operate.
Note: The red Emergency Stop button at the
ground controls will stop all machine operations,
even if the key switch is turned to the platform
control.

Test the Horn

Genie specifications require that this procedure be
performed every 250 hours or quarterly, whichever

The horn is activated at the platform controls and
sounds at the ground as a warning to ground
personnel. An improperly functioning horn will
prevent the operator from alerting ground
personnel of hazards or unsafe conditions.
1 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.
Note: Rotate the red Emergency Stop button at
platform control one quarter turn in a clockwise
direction to restore the power supply. The red
Emergency Stop button returns automatically to
the out, or on position.
2 Push down the horn button at the platform
controls.
Result: The horn should sound.
