INSTALLATION, continued
Improper installation of anchoring devices or installation
into aged or unsound concrete could result in death or
serious injury.
The dock face must be ush with curb angle to assure
proper bumper mounting.
20. Mount dock bumpers to face of dock. Downhill welds are
unacceptable. See Fig. 17 or 18.
21. Plug or wire in electrical cords and connect power to
dock leveler.
Manually support the lip when storing the lip lock. Stand
clear of the lip when removing support. The lip is free to
move downward when support is removed. Anyone in the
path of the lip when it moves downward can be struck.
Keep your hands, ngers and head away from the lip
when it is released. They could be struck by the lip or
caught between the lip and other parts of the dock leveler
resulting in death or serious injury.
DO NOT REMOVE MAINTENANCE STRUT WITHOUT
HYDRAULIC PRESSURE OR A MECHANICAL LIFTING
DEVICE SUPPORTING RAMP. Raise ramp with
hydraulic pressure or mechanical device before storing
maintenance strut. Stand clear of ramp and lip when
hydraulic pressure or mechanical lift is applied or
removed. Ramp and lip are free to move downward
when support is removed. Removing support without
hydraulic pressure could allow ramp to drop RAPIDLY. If
the dock leveler was raised using a mechanical device,
it should be lowered using the same device.
22. Lift up on the hinged lip and store the lip lock under the
ramp.
23. Two people are needed to store the maintenance strut.
a. One person must push and hold the raise button
until dock leveler reaches its highest position and
hold dock leveler in its highest position.
b. The second person unpins the maintenance strut
from the bracket on the ramp and stores it on the
subframe. See Fig. 15 and the instruction label on
maintenance strut.
