Leveling The Rear Frame - Kelley aFX-C User Manual

insTaLLaTion,
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.
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
transition angle of the rear angle is level with the rear pit
curb angle and the leveling screws are 1/4" from the top
transition angle which indicates that legs are in contact
with pit floor. Repeat on each leg until the transition
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 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.
5. Check and adjust the leveler for square, shim the rear
as required, see Fig. 20. The sides of the leveler deck
should be centered in the pit opening. Tack weld the rear
angle to rear curb angle in 4 places min 3/8", one at or
near each leveling screw.
noTe:
Do not weld out the rear angle until after setting the front
supports.
