CHECKLIST B PROCEDURES
B-3
Inspect the Tires and Wheels
(including castle nut torque)
Genie specifications require that this procedure be
performed every 250 hours or quarterly, whichever
comes first.
Maintaining the tires and wheels in good
condition is essential to safe operation and good
performance. Tire and/or wheel failure could result
in a machine tip-over. Component damage may
also result if problems are not discovered and
repaired in a timely fashion.
1 Check the tire surface and sidewalls for cuts,
cracks, punctures and unusual wear.
2 Check each wheel for damage, bends and
cracks.
3 Remove the cotter pin and check each castle
nut for proper torque. Refer to Section 2,
Specifications.
Note: Always replace the cotter pin with a new one
when removing the castle nut or when checking
the torque of the castle nut.
4 Install a new cotter pin. Bend the cotter pin to
lock it in place.
B-4
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.
Note: As a safety feature, selecting
and operating the ground controls will override the
platform controls, except the platform red
Emergency Stop button.

out the red Emergency Stop button to the on
position at both the ground and platform

Note: The red Emergency Stop button at the
ground controls will stop all machine operation,
even if the key switch 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,
