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.

FIGURE 1 - 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 Safe-T-StrutTM or other

supporting device.

• 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 so

that it is supported by the lip supports and

that it is level with the surrounding dock

floor.

• 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 Safe-T-Struttm. See below right.

This can be done with the assistance of

another person by:

- Raise leveler until platform reaches its

highest position and lip extends.

Continue to maintain this position.

- Then have assistant insert the smaller end

of the Safe-T-StrutTM through the hole in

the middle of the leveler lip and place the

strut’s wider open end over the base

located on the leveler’s front frame. Align

the holes on the base and the Safe-T-

StrutTM so that the leveler may be secured

with the retaining pin and safety clip.

- Release the pushbutton on powered

levelers allowing the Safe-T-StrutTM to rest

on the underside of the lip.

• 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.

Remove the Maintenance Support.

• For Safe-T-StrutTM removal, have an

assistant raise the leveler to its highest

position with lip fully extended. Release the

safety clip and remove retaining pin. Lift strut

off base, and remove from lip. Return the

Safe-T-StrutTM to the proper storage position.

• 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.

RITE-HITE®RHH Dock Leveler Owner’s Manual

OWNER RESPONSIBILITY

1. The owner should recognize the inherent danger of

the interface between dock and transport vehicle.

The owner should, therefore, train and instruct

operators in the safe use of dock equipment in

accordance with the information provided below.

The manufacturer shall publish, provide to the initial

purchaser, and make the following information

readily available to owners:

•Installation instructions

•Recommended initial and periodic inspections

procedures

•Maintenance procedures

•Operating instructions

•Descriptions or specifications for replaceable or

repairable parts

•Tables identifying the grade (slope) for all

variations of length or configuration of the dock

equipment

•Information identifying the maximum

uncontrolled drop encountered upon sudden

removal of support while within the working

range of the equipment.

It shall be the responsibility of the owner to verify

that the material listed in this section has been

received and that it is made available for the

instruction and training of personnel entrusted with

the use or maintenance of the dock equipment.

2. When a transport vehicle is parked at a loading

dock, it is important that the vehicle is relatively

perpendicular to the dock face and in close contact

with at least one of the dock bumpers.

3. Nameplates, cautions, instructions, and posted

warnings shall not be obscured from the view of

operating or maintenance personnel for whom such

warnings are intended.

4. Manufacturer’s recommended periodic maintenance

and inspection procedures in effect at date of

shipment shall be followed, and written records of

the performance of these procedures should be kept.

5. As with any piece of machinery, dock equipment

requires routine maintenance, lubrication, and

adjustments. Your local RITE-HITE®representative

offers owners the option of a Planned Maintenance

Program (P.M.P.). As part of this service, your local

RITE-HITE®representative will do all routine

maintenance, lubrication, and adjustments.

6. Dock equipment that is structurally damaged shall

be removed from service, inspected by a

manufacturer’s authorized representative, and

repaired as needed before being placed back in
