OPERATING PROCEDURE
Before loading or unloading a vehicle at
your loading dock while using a Lock & Load
vehicle restraint, always visually inspect to
be sure that the restraint is engaged with the
Rear Impact Guard (RIG). If the restraint is
still not engaged after backing the trailer
firmly against the dock bumpers, secure the
trailer by other means.
Be sure that the area around the RIG
assembly is clear of obstructions.
Always operate the Lock & Load vehicle
restraint from the top of the dock.
Inspect all restraint lights daily to make
certain they work properly.
Perform maintenance on restraints in
accordance with Maintenance on page 11 of
this manual.
Lock & Load vehicle restraints should be
operated only by authorized personnel who
have read and understand the Owner’s
Manual.
If you have questions, Call your local
representative or NOVA at (800) 236-7325.
FAILURE TO FOLLOW THESE PROCEDURES
COULD RESULT IN SERIOUS INJURY OR
DEATH.
