If the hydraulic connectors are accessible, connections can be made and the
lift can be powered open using the hydraulic power unit (HPU). See Hydraulic
Information section. Skip instructions three and four.
Ensure lifting eyes have been removed completely before attempting to raise the
platform when using the HPU.
3. If manually raising the platform of the lift, remove the lifting eyes and install them into
the second set of holes. The second set of holes (off platform centerline) have a nut
welded to the bottom of the platform and are used to manually raise the platform for
access during installation. Reattach the chain or strap.
Lifting eyes must be hand tightened only. Over torquing the lifting eyes may cause
them to fail.
Lifting eyes must be removed from holes securing the platform to the base frame
(holes along platform center line) before attempting to raise the platform.
4. Using the lifting eyes, raise the platform and engage the maintenance device and then
lower the platform onto the maintenance device.
See Section 6.1 Maintenance Device
Ensure the roller end of the platform is not lifted off of the upper rollers.
