While you were cycling the dockleveler upon completion of the installation, you
should have noticed that the dockleveler would raise to a certain point after which
time the lip would extend. Releasing the raise button would allow the dockleveler to
lower to the full below dock position after which the lip would fold. Pressing the raise
button would then cause the dockleveler to raise. When the lip cleared the keepers,
the raise button could be released and the dockleveler would rest in the cross traffic
(stored) position. If this operation was not apparent, one of three adjustments may
be required:
1. If the dockleveler did not raise but pump/motor was running, the main pressure
relief may need adjustment. Pressure relief can be found in the steel block that
connects the reservoir to the motor.

The adjustment is an allen wrench adjustment located directly beneath a hex
plug on the side of the block. Remove the hex plug to access the allen screw.
Turning the screw clockwise will increase the pressure. Remember, if you
have a 3 phase power source, the motor may be running backwards.
