A hard hat or other applicable head protection
should always be worn when working under or
around a dock leveler.
Always stand clear of platform lip when working in
front of the dock leveler.
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.
Note: If an excessive transition exists between the
dock floor and leveler and/or lip does not contact
both lip keepers evenly, contact Systems, LLC
Technical Services for further instructions.
3. Turn the main electrical power ON.
4. Raise the leveler platform fully by depressing and
holding the RAISE button.
Note: The platform of a properly operating dock
leveler will automatically stop rising when it reaches
its maximum full raised height, at which point, the
lip extends. When the lip is fully extended, the
powerpack will go into pressure relief. (If the lip does
not extend correctly, see Troubleshooting section.)
5. Release the RAISE button to lower the platform.
As long as there is no vehicle present at the dock,
the platform will lower to the full below-dock position
as the lip folds.
Note: If a transport vehicle is present, the platform
will lower until the lip rests on the transport vehicle’s
bed.
6. When the platform lowers to the full below-dock
position, depress 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).
Put New Dock Leveler Into Service
Note: For dock levelers equipped with the
Auto Return To Dock (ARTD), the platform will
automatically return to the cross-traffic position if
the ARTD is enabled. When the platform is at the
full below-dock position, there is a six-second delay
before the platform will automatically rise to the
cross-traffic position.
7. Perform steps 4-6 at least four times to purge any
air that may be in the hydraulic system and to ensure
proper operation.
8. 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.
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.
In addition, it is recommended and good safety
practice to use an additional means to support
the dock platform and lip anytime when physically
working in front of or under the dock leveler. This
additional means may include, but is not limited to a
boom truck, fork truck, stabilizing bar or equivalent.
9. Secure the maintenance prop with the
maintenance prop lock-out.
10. With the maintenance prop supporting the
platform, remove the lifting brackets.
11. Release the maintenance prop by unlocking the
lock-out.
12. Depress 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.
