SAFETY PRECAUTIONS
Each Series 622 Hand Hoist is built in accordance with the specifications contained herein and at the time of
manufacture complies with our interpretation of applicable sections of the * American Society of Mechanical
Engineers Code B30.16 “Overhead Hoist” and the Occupation Safety and Health Act.
The safety laws for elevators and for dumbwaiters may specify construction details that are not necessarily
incorporated in CM industrial hoists. We recommend the use of equipment that meets state and national safety
codes. Columbus McKinnon Corporation cannot be responsible for applications other than those for which CM
equipment is recommended.
THIS SYMBOL POINTS OUT IMPORTANT SAFETY INSTRUCTIONS WHICH IF NOT FOLLOWED
COULD ENDANGER THE PERSONAL SAFETY AND/OR PROPERTY OF YOURSELF AND OTH-
ERS. READ AND FOLLOW ALL INSTRUCTIONS IN THIS MANUAL AND ANY PROVIDED WITH
THE EQUIPMENT BEFORE ATTEMPTING TO OPERATE YOUR SERIES 622 HOIST.
! !
Consult Columbus McKinnon Corporation for any usage of Series 622 Hoists that do not involve raising of the load on the lower hook, or
usage of Series 622 Hoists in the inverted position. Using hoists, without special precautions, in such applications may cause an accident
that could result in injury and/or property damage.

DO’S AND DO NOT’S
Safe Operation of Hoists
The following are Do’s and Do Not’s for safe opera-
tion of overhead hoists. Taking precedence over
any specific rule listed here, however, is the most
important rule of all, USE COMMON SENSE. A few
minutes spent reading these rules can make an
operator aware of dangerous practices to avoid and
precautions to take for his own safety and the safe-
ty of others. Frequent examinations and periodic
inspections of the equipment as well as a conscien-
tious observance of safety rules may save lives as
well as time and money.
