SAFETY WARNINGS
LOCKOUT/TAGOUT PROCEDURES
The Occupational Safety and Health Administration (OSHA) requires, in addition to posting safety warnings and barri-
cading the work area (including, but not limited to, trucking office and loading docks), that 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®does not recommend any particular lockout device, but recommends the utilization of an OSHA approved
device (refer to OSHA regulation 1910.147). RITE-HITE®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.
When working with electrical or electronic con-
trols, make sure that the power source has been
locked out and tagged out according to OSHA
regulations and approved local electrical codes.
XXXXXXXXXXXX

LOCKOUT/TAGOUT
This is a statement of serious hazard. Failure to
follow the listed instructions could place the
individual at risk of serious injury or death.
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 pro-
cedure is ignored the possibility of personal
injury may exist.
IMPORTANT is used to draw attention to a pro-
cedure that needs to be followed to prevent
machine damage.

OTHER IMPORTANT OPERATIONAL SAFETY WARNINGS
Never be under the dock leveler platform or lip
without:
• Installing the maintenance strut.
• If lip needs to be extended, follow
procedures shown under Safety Devices on
the following page.
• Turning off power to the control box.
• Locking out and tagging out the main
power source, as shown under Safety
Warnings on preceding page.
Always barricade the dock leveler at ground
level and dock level from any form of traffic
when maintenance is required.
Inspect the dock leveler monthly to ensure that
there are no broken or worn parts which could
cause injury to personnel or damage to the
equipment.
• Before starting installation or maintenance,
check and follow the safety procedures of
the facility where the dock leveler is being
installed.
• Never enter a truck/trailer until its brakes are
set, air has been dumped from air ride
suspension (if applicable), and you have
visually inspected to be sure truck/trailer is
securely held in place by a vehicle restraint
or wheel chock per OSHA regulations.
• Never operate the leveler with you, anyone,
or anything on, or in front of the leveler, or
without a truck/trailer parked in position, or
from on the truck/trailer bed.
• DO NOT operate with anyone under platform
or in front of the lip.
• When leveler is not in use, always store it.
• If a malfunction does occur, always call your
authorized RITE-HITE®service representative
immediately.

SAFETY DEVICES
Never be under the dock leveler platform or lip
without:
• Installing the Maintenance Strut. See right.
• Lockout/Tagout power supply.
- Turn off the power to the control box.
- Lockout/tagout the main power source, as
shown under Safety Warnings on the
inside front cover of this manual.
- Always barricade the leveler at dock level
and drive level to prevent any
unauthorized use of the leveler.
• If you are unable to install the Maintenance
Support properly, contact your authorized
RITE-HITE® Service Representative or RITE-
HITE® Customer Service at 1-414-355-2600.
• Post warnings and barricades at dock level
and at drive level to indicate that work is
being done around and under the leveler
platform.
• Lockout/Tagout power to the leveler and post
warnings when work is being performed on
the leveler.
The operation handle also serves as a
maintenance strut preventing the leveler from
rotating onto the maintenance personnel.
To install the strut:
• Rotate the leveler to its rearward position.
• Remove the clevis pin attaching the lip
latch to the underside of the lip.
When lifting lip (approx. 110 lbs.) use lifting
device (crane). Lifting by hand may cause
back injury.
• Rotate the lip up and over. Place the
handle in the socket provided.

INSTALLATION INSTRUCTIONS
PREPARATION PRIOR TO INSTALLATION
1. Check pit to insure it meets pit details. If pit does not
match pit details, contact your local representative or
RITE-HITE®before proceeding.
NOTE:
Unit may not operate properly if pit is not correct.
2. The dock must be clean, straight, and free of
protrusions. Adequately sized dock edge steel must
be an integral part of the dock or a transition plate
with face plate must be utilized.
INSTALLATION PROCEDURES
1. Center the leveler in place. The top of faceplate
should be 5/16” ± 1/16” below the top surface of
dock edge steel (or transition plate if used).
2. Weld the leveler and bumper blocks to dock edge
steel and/or transition plate. Use 7018 welding rod.
3. All anchor holes must be anchored with 5/8” x 5L
concrete anchor bolts (RH# 65639) or plug welded
to dock edge steel. See figure 1.
4. Clean and paint all welded joints.
5. Lubricate dock leveler per lubrication chart. See
figure 2.
