Coffing Hoists EC3 Series Operating, Maintenance & Parts Manual page 3

Improper operation of a hoist can create a potentially
hazardous situation which, if not avoided, could result in
death or serious injury. To avoid such a potentially hazardous
situation, THE OPERATOR SHALL:
a. NOT operate a damaged, malfunctioning or unusually
performing hoist.
b. NOT operate the hoist until you have thoroughly read and
understood this Operating, Maintenance and Parts Manual.
c. NOT operate a hoist which has been modified without the
manufacturer's approval or without certification that it is in
conformity with ANSI/AMSE B30 volumes.
d. NOT lift more than rated load for the hoist.
e. NOT use hoist with twisted, kinked, damaged, or worn load
chain.
f. NOT use the hoist to lift, support, or transport people.
g. NOT lift loads over people.
h. NOT operate a hoist unless all persons are and remain clear
of the supported load.
i. NOT operate unless load is centered under hoist.
j. NOT attempt to lengthen the load chain or repair damaged
load chain.
k. Protect the hoist's load chain from weld splatter or other
damaging contaminants.
l. NOT operate hoist when it is restricted from forming a
straight line from hook to hook in the direction of loading.
m. NOT use load chain as a sling, or wrap chain around load.
n. NOT apply the load to the tip of the hook or to the hook
latch.
o. NOT apply load unless load chain is properly seated in the
chain sprocket(s).
p. NOT apply load if bearing prevents equal loading on all load
supporting chains.
q. NOT operate beyond the limits of the load chain travel.
r. NOT leave load supported by the hoist unattended unless
specific precautions have been taken.
s. NOT allow the load chain or hook to be used as an electrical
or welding ground.
t. NOT allow the load chain or hook to be touched by a live
welding electrode.
u. NOT remove or obscure the warnings on the hoist.
v. NOT operate a hoist on which the safety placards or decals
are missing or illegible.
w. NOT operate a hoist unless it has been securely attached to
a suitable support.
x. NOT operate a hoist unless load slings or other approved
single attachments are properly sized and seated in the
hook saddle.
y. Take up slack carefully - make sure load is balanced and
load holding action is secure before continuing.
z. Shut down a hoist that malfunctions or performs unusually
and report such malfunction.
aa. Make sure hoist limit switches function properly.
ab. Warn personnel of an approaching load.
Improper operation of a hoist can create a potentially
hazardous situation which, if not avoided, could result
in minor or moderate injury. To avoid such a potentially
hazardous situation, THE OPERATOR SHALL:
a. Maintain firm footing or be otherwise secured
when operating the hoist.
b. Check brake function by tensioning the hoist prior
to each lift operation.
c. Use hook latches. Latches are to retain slings, chains, etc.
under slack conditions only.
d. Make sure the hook latches are closed and not supporting
any parts of the load.
e. Make sure the load is free to move and will clear
all obstructions.
f. Avoid swinging the load or hook.
g. Make sure hook travel is in the same direction as shown
on the controls.
h. Inspect the hoist regularly, replace damaged or worn parts,
and keep appropriate records of maintenance.
i. Use CM Hoists recommended parts when repairing
the unit.
j. Lubricate load chain per hoist manufacturer's
recommendations.
k. NOT use the hoist's overload limiting clutch to measure
load.
l. NOT use limit switches as routine operating stops.
They are emergency devices only.
m. NOT allow your attention to be diverted from operating
the hoist.
n. NOT allow the hoist to be subjected to sharp contact with
other hoists, structures, or objects through misuse.
o. NOT adjust or repair the hoist unless qualified to perform
such adjustments or repairs.
SAFETY PRECAUTIONS
Each Electric Chain Hoist is built in accordance with the specifications
contained herein and at the time of manufacture complies with
our interpretation of applicable sections of *American Society of
Mechanical Engineers Code (ASME) B30.16 "Overhead Hoists," the
National Electrical Code (ANSI/NFPA 70) and the Occupational Safety
and Health Act (OSHA). Since OSHA states the National Electrical Code
applies to all electric hoists, installers are required to provide current
overload protection and grounding on the branch circuit section in
keeping with the code. Check each installation for compliance with the
application, operation and maintenance sections of these articles.
The safety laws for elevators, lifting of people and for dumbwaiters
specify construction details that are not incorporated into
the hoists. For such applications, refer to the requirements of
applicable state and local codes, and the American National
Safety Code for elevators, dumbwaiters, escalators and moving
walks (ASME A17.1). Columbus McKinnon Corporation cannot be
responsible for applications other than those for which COFFING
equipment is intended. DO NOT use for guided loads.

THIS SYMBOL POINTS OUT IMPORTANT SAFETY
INSTRUCTIONS WHICH IF NOT FOLLOWED COULD
ENDANGER THE PERSONAL SAFETY AND/OR PROPERTY
OF YOURSELF AND OTHERS. READ AND FOLLOW ALL
INSTRUCTIONS IN THIS MANUAL AND ANY PROVIDED
WITH THE EQUIPMENT BEFORE ATTEMPTING TO
OPERATE YOUR HOIST.
