PiT cHeck

1. Check entire dock leveler pit for proper construction
according to certified pit drawings (publication 5567).
Check to be sure that the pit walls are square and plumb.
Prep the pit floor for rear leveler legs. The pit should
be clean and free of any excess debris. Chip excess
concrete or large residual concrete flash left over from
pouring the pit. Area surrounding the leveling feet should
be smooth and free of excessive lumps. Check electrical
service running to the pit to assure it agrees with the
correct location and voltage for the junction box. Inspect
the pit and remove all loose trash and construction
debris. Verify the pit matches pit details for your leveler.
See the installation troubleshooting on page 14 if the pit
varies from the specification.

Place barricades around pit on dock floor and drive while
installing, maintaining or repairing dock leveler.
Power to control box must be from fused disconnect
supplied by others. For correct fuse size refer to wiring
diagrams on pages 15-24 of this manual. Before doing any
electrical work, make certain the power is disconnected
and properly tagged or locked off. All electrical work
must be done by a qualified technician and must
meet all applicable codes. If it is necessary to make
troubleshooting checks inside the control box with the
power on, USE EXTREME CAUTION. Do not place fingers
or uninsulated tools inside the control box. Touching
wires or other parts inside the control box could cause
electrical shock, resulting in death or serious injury.
1. The control station, user's manual and dock bumpers
are attached to the subframe of the dock leveler. The
maintenance strut has a plastic tie wrap holding it to the
subframe, remove these it before placing the leveler into
the pit. Make sure the customer gets the user's manual
and is properly trained.
