Test the Emergency Stop

Genie requires 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.
Note: As a safety feature, selecting and operating
the ground controls will override the platform
controls, except the platform red Emergency Stop
button.
1 Start the engine from ground controls.
2 Push in the red Emergency Stop button to the
off position.
Result: The engine should shut off and no
machine functions should operate.
3 Start the engine from platform controls.
4 Push in the red Emergency Stop button to the
off position.
Result: The engine should shut off and no
machine functions should operate.
Note: The red Emergency Stop button at the
ground or platform controls will stop all machine
operation without regard to the position of the key
switch.

Test the Automotive-style Horn

Genie requires that this procedure be performed
every 250 hours or quarterly, whichever comes
first.
A functional horn is essential to safe machine
operation. 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 controls and
pull out the red Emergency Stop button to the
on position at both the ground and
platform controls.
2 Push down the horn button at the platform
controls.
Result: The horn should sound.
Note: If necessary, the horn can be adjusted to
obtain the loudest volume by turning the
adjustment screw near the wire terminals on the
horn.
