noTe:
Check the pit floor for uneven or excess concrete in the area
around the leveling feet 1"-6" from the rear wall. Use chisel
to level out area if necessary.
3. Move the dock leveler back to the rear pit curb angle.
See Fig. 6. With the rear leveler angle touching the rear
pit angle, square up the sides of the pit to the sides of
the leveler. The gap should be even on both sides. The
rear frame angle should be within 1/4" on either sides of
the pit curb angle.
noTe:
The rear frame angle should be about 1/2" lower than the pit
curb angle before leveling. This is normal. See Fig. 7.

4. Using a 1/2" square drive (1/2" ratchet or impact tool)
work from one side to the other, turn each of the leveling
screws on the rear angle, counter clockwise until the top
surface of the rear angle is level with the rear pit curb
angle. Repeat on each leg until all are legs in contact
with the pit floor and the top frame angle is flush with the
rear curb angle. See Fig 8.
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 floor curb steel. The
front end should be level and parallel with the rear frame
angle for proper operation. Unequal Shimming 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. Failure to
do so can result in product damage.
5. Check and adjust the leveler for square and in firm
contact with the rear angle. The sides of the leveler
should have a 1/2" gap and parallel with the sides of
the pit. Tack weld the rear angle to rear curb angle in 4
places min 3/8" at the center and at both ends. See Fig.
9 and 10.
noTe:
Do not weld out the rear angle until after setting the front
supports.
