INSTALLATION
5. 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 its full raised height, at which point,
the lip extends.
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 transport vehicle.
(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 Systems, Inc.
Technical Services for further instructions.
3. Install the dock bumpers as required.
4. Turn the main electrical power ON.
Put New Dock Leveler Into Service
7. When the platform lowers to the full below-dock
position, wait 5 seconds after the lip has folded
to allow lip cylinder to fully retract. 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 to purge
any air that may be in the hydraulic system and to
ensure proper operation.
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 and front
shipping bar in between lip keepers.
11. 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.
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.
