GENERAL INFORMATION

This manual contains important information to help you properly
install, operate and maintain your Series 622A Hoist for maximum
performance, economy and safety.
Please study its contents thoroughly before putting your hoist
into operation. By practicing correct operating procedures and by
carrying out the recommended preventive maintenance suggestions,
you will be assured of long, dependable and safe service. After
you have completely familiarized yourself with the contents of this
manual, we recommend that you carefully file it for future reference.
The information herein is directed to the proper use, care and
maintenance of the Series 622A Hoist and does not comprise a
handbook on the broad subject of rigging.
Rigging can be defined as the process of lifting and moving heavy
loads using hoists and other mechanical equipment. Skill acquired
through specialized experience and study is essential to safe rigging
operations. For rigging information, we recommend consulting a
standard textbook on the subject.
CM REPAIR/REPLACEMENT POLICY
All Columbus McKinnon (CM) Series 622A Hoists are inspected and
performance tested prior to shipment. If any properly maintained
hoist develops a performance problem, within one year of shipment,
due to a material or workmanship defect, as verified by CM, repair
or replacement of the unit will be made to the original purchaser
without charge. This repair/replacement policy applies only to Series
622A Hoists installed, maintained and operated as outlined in this
manual, and specifically excludes hoists subject to normal wear,
abuse, improper installation, improper or inadequate maintenance,
hostile environmental effects and unauthorized repairs/modifications.
We reserve the right to change materials or design if, in our opinion,
such changes will improve our product. Abuse, repair by an
unauthorized person, or use of non-CM replacement parts voids
the guarantee and could lead to dangerous operation. For full Terms
of Sale, see Sales Order Acknowledg-ment. Also, refer to the back
cover for Limitations of Warranties, Remedies and Damages, and
Indemnification and Safe Operation.
UNPACKING
After opening the carton, the hoist should be carefully inspected
for damage which may have occurred during shipment or handling.
Check the hoist frame for dents or cracks and inspect the load chain
for nicks and gouges. If shipping damage has occurred, refer to the
packing list envelope on the carton for claim procedure.
Operating a unit with obvious external damage may cause load to
drop and that may result in personal injury and/or property damage.
Carefully check unit for external damage prior to installation.

OPERATING INSTRUCTIONS
After mounting and before placing in service, check the hoist for
proper operation. Before operating the 3 and 5 ton units, make
sure that all strands of chain are straight and have no twists (due to
capsized hook). If the chain is twisted, reverse capsize. To operate
the hoist, pull on the hand chain as indicated below.

OF HAND CHAIN
Operate the hoist with no load and then a light load of approximately
50 pounds (23 Kg.) times the number of load supporting chains to
make sure it operates properly and the brake holds the load when
the hand chain is released; then operate with a rated load as shown
on the capacity plate.
Operating the 3 and 5 ton hoists in the lifting direction with the hook
block in contact with the frame and/or hoist hanger may break the
chain and allow the load to drop.
TO AVOID INJURY:
Stop operating in the lifting direction when the hook block
contacts the hoist frame and/or hanger, as noted by sudden
increase in hand chain pull or tipping of the hook block.

SAFETY PROCEDURES

1. The hoist must always be rigged to lift in a straight line from
hook to hook. The hoist must always be free to swivel on the
upper hook. Under no condition should the hoist frame be
allowed to bear on any support when in use as this would
cause bending of the hook or frame and damage the unit.
2. When preparing to lift or move a load, be sure that the
attachments to both hooks are firmly seated in the saddles
of the hooks. Avoid off center loading of any kind especially
loading on the tip of the hook. Also observe that the chain
hangs straight (without twist) from hoist to lower hook.
3. When lifting, raise the load only enough to clear the floor or
support, and check to be sure brake will hold load and that
attachments to the load are firmly seated. Continue the lift only
after you are assured the load is free of all obstructions.
4. Do not load beyond the rated capacity of the hoist.
Rated capacity can be achieved with the following
hard chain pulls:
