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.
