6. Raise the leveler platform fully by pushing and
holding the RAISE button .
NOTE: The platform of a properly operating dock
leveler will automatically stop rising when it
reaches approximately 2 – 3 inches from its
full raised height, at which point, the lip
extends. When the lip is fully extended, the
platform will continue to rise until it reaches
the full raised position. (If the lip does not
extend or extend fully, see Platform Rises to
Full Height, But Lip Does Not Fully Extend in
the Troubleshooting section.)
6. Release the RAISE button to lower the platform.
As long as there is no truck present at the dock,
the platform will lower to the full below-dock
position as the lip folds.
NOTE: If a truck is present, the platform will lower
until the lip rests on the truck/trailer bed. (See
Operating Instructions in Operation section.)
1. Disconnect the external lifting device and chains
from the lifting brackets.
2. Check that the leveler is flush with the dock floor
and that the platform lip contacts both lip keepers
evenly.
If an excessive transition exists between the dock
floor and leveler and/or lip does not contact both
lip keepers evenly, contact Poweramp Technical
Services for further instructions.
3. Install the dock bumpers as required.
4. Turn the main electrical power ON.

7. When the platform lowers to the full below-dock
position, the lip will fold. Push and hold the
RAISE button until the platform rises just enough
to clear the lip keepers, then release the RAISE
button to allow the platform to lower to the
cross-traffic (stored) position (lip engages lip
keepers).
8. Perform steps 5 – 7 at least four times make sure
the leveler functions properly and there is no
binding.
9. Raise the platform fully. Hold the platform at this
position using the RAISE button and
move the maintenance prop to the
service (upright) position. Release the RAISE
button to allow the platform to lower until it is
resting on the maintenance prop.
10. With the maintenance prop supporting the
platform, remove the lifting brackets
11. If equipped with vertical weather seals, position
the seals so that the seals are directly under and
aligned with the overhead door.
11. If equipped with toe-guards, support the toe
guards, remove the cotter pin used in shipping
and carefully release the toe guards.
13. Push and hold the RAISE button until the
maintenance prop drops to its stored position.
Release the RAISE button and allow the platform
to lower fully. Check operation of toe-guards.
14. When the platform lowers to the full below-dock
position, the lip will fold. Push and hold the
RAISE button until the platform rises just enough
to clear the lip keepers, then release the RAISE
button to allow the platform to lower to the
cross-traffic (stored) position (lip engages lip
keepers).
Always stand clear of platform lip when working in
front of the dock leveler. Serious personal injury or
death may result.
Unless the dock leveler is equipped with a tethered
remote, two people are required to engage the
maintenance prop: one person to operate the unit,
the other person to engage the maintenance prop.
