Maintenance Devices
Do not enter under the platform unless secure using the supplied
maintenance devices.
The supplied maintenance devices are designed to support only the
unloaded lift. Failure to remove loads before engaging the maintenance
devices may result in failure of the maintenance devices or lift and
cause severe injury or death, and damage to the lift.
If the lift is equipped with a mechanical or proximity up limit switch that
prevents the lift from raising high enough to engage the maintenance
devices, the switch will need to be bypassed to engage the maintenance
device.
1. Ensure all debris, tools, and personnel are clear of the lift. Ensure load has been removed.
2. Raise the lift to the fully raised position.
3. Engage the maintenance device(s).

The end of the device must be
resting on the base frame.
Standing style maintenance
devices must only be used
on the hinged end of the base
frame.
When engaged, the

resting on the underside of the
platform. Damage may occur
if the maintenance device
is resting on the structural
reinforcements.
If the lift is equipped with a
limit switch, the maintenance
device may be stowed on the
roller end of the base frame.
