Inadequate lifting equipment or practices can cause a
load to fall unexpectedly. Make sure the lifting chain or
other lifting devices are in good condition and have a
rated capacity of at least 3,500 lbs for the lifting angle
used. Never allow anyone to stand on or near the dock
leveler when it is lifted or placed into the pit. Stand clear
of the dock leveler when it is placed into the pit. Failure
to follow this warning can allow the dock leveler to fall,
tip, or swing into people, resulting in death or serious
injury.
Route power cord clear of edges and resting surfaces
so that it is not damaged during lifting and placement.
Plug end may be routed up through the rear hinge until
needed.

The rear edge of the dock leveler should be level or
slightly (1/16" maximum) below dock level.
The top surface of the dock leveler should be level and a
smooth transition with the dock oor curb steel. The front
end should be level and parallel with the rear frame angle
for proper operation. Unequal adjustment of the front
supports may be required to obtain a level front edge.
Turn off all electrical power to the leveler if it has been
previously connected. Welding with dock levelers power
connected can damage the electrical components. A
ground must be attached to the leveler frame.

The lifting support frame will drop rapidly to the pit oor
when the retainer bolts are removed. Keep your hands
and feet out from under the dock leveler when releasing
the frame. Failure to do so could result in death or serious
injury.
Air pressure or mechanical support must be maintained
under the ramp to hold it in the raised position until the
maintenance strut is in place. DO NOT WORK UNDER
THE DOCK LEVELER RAMP OR LIP UNLESS THE
MAINTENANCE STRUT IS IN PLACE AND PINNED, AND
LIP LOCK IS IN PLACE AND SUPPORTING THE LIP.
