DANGER
DANGER
Read and follow all instructions, warnings, and maintenance schedules in
the manual and on placards.
Vehicle restraint operation and servicing is restricted to authorized
personnel.
1. Before using the vehicle restraint:
Remove any debris, snow, or ice that may obstruct vehicle restraint
operation.
Alert personnel in the area of potential vehicle restraint operation and
ensure area is clear.
Operate the vehicle restraint through one complete cycle inspecting
it for proper operation and light sequence. Advise maintenance
personnel of any damage or improper operation immediately. Remove
all malfunctioning or damaged vehicle restraints from service using
approved lockout/tagout procedures.
2. Before attempting to restrain a transport vehicle:
Verify that transport vehicle is positioned squarely against dock
bumpers.
Inspect the transport vehicle's rear impact guard (RIG). Damaged or
missing RIGs, lift gates, plates or other obstructions may not allow the
vehicle restraint to securely capture the RIG. Wheel chocks must be
used whenever the ability for the vehicle restraint to capture the RIG is
in question. (NOTE: The transport vehicle's suspension and load
condition will affect trailer height.)
3. After activating vehicle restraint:
Verify that the transport vehicle's RIG has been restrained successfully.
In the event this cannot be determined, use wheel chocks in addition
to restraint.
If equipped with a light communication system, load and unload on
GREEN light only.
4. Maintenance or service must be performed by authorized personnel only.
Follow approved lockout/tagout procedures.
FAILURE TO FOLLOW THESE INSTRUCTIONS WILL RESULT IN
DEATH OR OTHER SERIOUS INJURY.

To manually unlock the TPR UniLock, the dock operator must press the RELEASE button on the controller inside the loading dock. This action causes the hook to rotate out past the anchor points and drop down into the housing, allowing the trailer to be released.
