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).
• Standing Style Maintenance Devices:
Remove the device from the
stowed position.
Install the maintenance device
over the post located on the
hinged end of the base frame.
The end of the device must be
resting on the base frame.
Standing style maintenance
devices must only be used

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
