INSTALLATION
1. Disconnect the external lifting device
2. Install the dock bumpers as required.
3. Turn the main electrical power ON.
4. 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.
5. 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.)
6. Perform steps 4 & 5 at least four times to purge
any air that may be in the hydraulic system and to
ensure proper operation.
Put New Dock Leveler Into Service
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.
