OPERATING INSTRUCTIONS

CAUTION
Never operate the dock leveler when someone is in front of the lip.

Always restrain the truck/trailer being loaded/unloaded, i.e. by use of wheel chocks or
a truck restraint device.

1. Raise the dock leveler by gently pulling the release chain at rear of the deck. (Hold

the chain up until the dock rises to its highest position.) The lip will extend and lock
automatically. (FIGURE #1)

2. To lower the dock into its work position, walk to lip end of the dock. The weight of

the operator will lower the dock onto the truck or trailer. (FIGURE #2)

3. As soon as the lip is on the truck the dock is ready to be used to load or unload truck

or trailer.

4. While in use the dock will raise and lower with the movement of the vehicle and the

trailer.

5. When the truck/trailer departs the lip will fall to vertical and the dock may be walked

down to the cross traffic stored position with lip behind the night lock.

6. If necessary, raise the dock 6” above dock using the release chain, to allow the lip to

fall behind the night lock, and then walk the dock down to the cross traffic stored
position with lip behind the night lock.

WARNING:

DAMAGE TO THE DOCK LEVELER AND LIP WILL OCCUR IF THE LIP IS LEFT IN THE

EXTENDED POSITION WHEN A TRUCK BACKS INTO THE DOCK.

LIP SHOULD BE A

MINIMUM OF

4" TO 6" INSIDE THE

TRUCK/TRAILER
