1.1 Terms and Summary
This manual provides important information for personnel involved with the installation, operation and
maintenance of this product. Although you may be familiar with this or similar equipment, it is strongly
recommended that you read this manual before installing, operating or maintaining the product.
Danger, Warning, Caution and Notice
Throughout this manual there are steps and procedures that can present hazardous situations. The following
signal words are used to identify the degree or level of hazard seriousness.
Danger indicates an imminently hazardous situation which, if not avoided, will result in
death or serious injury, and property damage.
Warning indicates an imminently hazardous situation which, if not avoided, could result in
death or serious injury, and property damage.
Caution indicates a potentially hazardous situation which, if not avoided, may result minor
or moderate injury or property damage.
Notice is used to notify people of installation, operation, or maintenance information which
is important but not directly hazard-related.
These general instructions deal with the normal installation, operation, and maintenance situations encountered with
the equipment described herein. The instructions should not be interpreted to anticipate every possible contingency
or to anticipate the final system, crane, or configuration that uses this equipment. For systems using the equipment
covered by this manual, the supplier and owner of the system are responsible for the system’s compliance with all
applicable industry standards, and with all applicable federal, state and local regulations/codes.
This manual includes instructions and parts information for a variety of hoist types. Therefore, all instructions and
parts information may not apply to any one type or size of specific hoist. Disregard those portions of the instructions
that do not apply.
Record your hoist’s Code, Lot and Serial Number (see Section 9) on the front cover of this manual for identification
and future reference to avoid referring to the wrong manual for information or instructions on installation, operation,
inspection, maintenance, or parts.
Use only Harrington authorized replacement parts in the service and maintenance of this hoist.

Equipment described herein is not designed for and MUST NOT be used for lifting, supporting, or transporting
people, or for lifting or supporting loads over people.
Equipment described herein should not be used in conjunction with other equipment unless necessary and/or
required safety devices applicable to the system, crane, or application are installed by the system designer, system
manufacturer, crane manufacturer, installer, or user.
Modifications to upgrade, rerate, or otherwise alter this equipment shall be authorized only by the original equipment
manufacturer.
If a below-the-hook lifting device or sling is used with a hoist, refer to ANSI/ASME B30.9, “Safety Standard for
Slings” or ANSI/ASME B30.20, “Safety Standard for Below-the-Hook Lifting Devices”.
Hoists used to handle hot molten material may require additional equipment or devices. Refer to ANSI Z241.2,
“Safety Requirements for Melting and Pouring of Metals in the Metalcasting Industry”.
Failure to read and comply with any one of the limitations noted herein can result in serious bodily injury or death,
and/or property damage.
It is the responsibility of the owner/user to install, inspect, test, maintain, and operate a hoist in accordance with
ANSI/ASME B30.21, “Manually Lever Operated Hoists” and OSHA Regulations. If the hoist is installed as part of a
total lifting system, such as an overhead crane or monorail, it is also the responsibility of the owner/user to comply
with the applicable ANSI/ASME B30 volume that addresses that type of equipment.
It is the responsibility of the owner/user to have all personnel that will install, inspect, test, maintain, and operate a
hoist read the contents of this manual and applicable portions of ANSI/ASME B30.21, “Manually Lever Operated
