FIGURE 1 - LOCKOUT/TAGOUT
LOCKOUT/TAGOUT PROCEDURES
The Occupational Safety and Health Administration requires that, in addition to posting safety warnings and barricading
the work area, the power supply has been locked in the OFF position or disconnected. It is mandatory that an approved
lockout device is utilized. An example of a lockout device is illustrated. The proper lockout procedure requires that the
person responsible for the repairs is the only person who has the ability to remove the lockout device.
In addition to the lockout device, it is also a requirement to tag the power control in a manner that will clearly note that
repairs are under way and state who is responsible for the lockout condition. Tagout devices have to be constructed and
printed so that exposure to weather conditions or wet and damp locations will not cause the tag to deteriorate or become
unreadable.
RITE-HITE® Corporation does not recommend any particular lockout device, but recommends the utilization of an
OSHA approved device (refer to OSHA regulation 1910.147). RITE-HITE® Corporation also recommends the review and
implementation of an entire safety program for the Control of Hazardous Energy (Lockout/Tagout). These regulations are
available through OSHA publication 3120.
This is the highest level statement. Failure to
follow the listed instructions will most likely result
in severe injury or death.
The statements used with this level of
warning deal with a safe operating
procedure. If the procedure is ignored, the
possibility of personal injury may exist.
IMPORTANT is used to draw attention
to a procedure that needs to be followed to prevent
machine or property damage.
When working with electrical or electronic controls,
make sure that the power source has been locked
out and tagged according to OSHA regulations and
approved local electrical codes.
SAFETY WARNINGS
This is a statement of serious hazard. Failure
to follow the listed instructions could place the
individual at risk of serious injury or death.

DEFINITION AND FUNCTION FEATURES
The MWL-1300 vehicle restraint is a truck and trailer locking
system used to help secure trucks and trailers to the face of a
loading dock. The barrier is deployed in front of the tire after the
trailer has been positioned against the dock bumpers.
This prevents forward movement of the truck/trailer that may
create an unsafe void between the face of the dock and the rear
end of the truck/trailer as the forklift travels from the loading dock
onto the trailer; and creates an obstruction noticeable (via outside
lights) to the truck driver, should the driver accidentally try to pull
the truck/trailer away while it is being serviced.
The normal mode of the restraint is the barrier assembly is stored
at the near end (closest to the dock). Inside lights should be
ashing red and outside lights should be ashing green.

FIGURE 4 - RESTRAINT LOCKING
The proper activation of the wheel restraint is monitored by:
• VISUAL CONTROL
— One set of ashing green and red lights located inside
the building for the dock personnel, and one set located
outside the building for the truck driver. See Figure 2.
FIGURE 3 - AUDIO CONTROLS
• AUDIO CONTROL
— A horn sounds inside and outside the building, warning
dock personnel when the locking mechanism is not
properly activated. In this case, the truck or trailer must
be secured by other means (wheel chocks etc.) prior to
servicing the trailer. See Figure 3.
Refer to Figure 4 for locations of these features:

• Before loading or unloading a vehicle at your
loading dock while using a vehicle restraint,
always visually inspect to be sure that the
barrier blocks the trailer wheel. If a condition
occurs that cannot be remedied by backing the
trailer rmly against the dock bumpers, secure
the trailer by other means.
• Inspect all restraint lights daily to make certain
they work properly.
• Perform maintenance on restraints in
accordance with Maintenance section in this
manual.
• Vehicle restraints should be operated only
by authorized personnel who have read and
understand the Owner’s Manual.
• Call your local representative or Rite-Hite at
[phone] with any questions.

Stored Position / Restraint UNLOCKED
If the MWL-1300 vehicle restraint is in the UNLOCKED
position (Barrier is up and stored all the way towards the
dock face), the Light communication System should give
the following signals:
1. OUTSIDE light ashing GREEN, which indicates that a
vehicle may pull into our out of the loading bay.
2. INSIDE light ashing RED, which indicates that loading
or unloading is not permitted, since the truck/trailer is
not secured against the building. See Figure 5.
Restraint LOCKING, Position Barrier In Front
Of Tire
It is assumed that the loading bay is empty (no truck). The
outside GREEN light and the inside RED light are ashing,
the Barrier is stored. A truck backs in. When the truck is
parked rmly against the bumpers, the operator can now
lock the vehicle.
To lock the vehicle, the operator deploys the Barrier in
front of a tire. The inside light will now be ashing green.
The truck may now be serviced. The light communication
and truck position are shown in Figure 6.
