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

DO NOT

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.

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.
