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 (Fig. 1).
Test the operation of the hoist before operating at rated capacity.
Operate the hoist with no load and then with a light load of approximately
50 pounds (23 Kg) times the number of load supporting chains to make
sure it operates properly and that the brake holds the load when the
hand chain is released.
NOTE:
Since the hand chain pulls can easily be applied by one person,
under no circumstances should more than one person operate the hoist
hand chain. Overloading can cause immediate failure of some load car-
rying parts or result in damage causing future failure at less than rated
capacity. When in doubt, use the next larger capacity
MILWAUKEE hoist.
5.
Do not wrap load chain around the load or bring the load in contact with
the hoist. Doing this will result in the loss of the swivel effect of the hook,
which could result in a twisted chain and a jammed liftwheel. The chain
could also be damaged at the hook.
6.
Do not move a load over the heads of other personnel. Warn personnel
of your intention to move a load in their area. Stand clear of all loads.
7.
Do not leave a suspended load unattended.
8.
Do not lower the hook to a point where the chain becomes taut between
the liftwheel and loose end pin.
9.
Do not run the lower hook block into the hoist frame. Frame and/or
chain guide damage may result.
10. Do not operate hoist with other than manual power.
11. Do not use this or any other overhead materials handling equipment for
lifting people.
12. Do not allow the load to bear against the hook latch. The latch is to help
maintain the hook in position while the chain is slack, before taking up
slack chain.

Recommended Procedures
1.
The hoist must always be rigged to lift in a straight line from hook to
hook.
a.
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 text book on the subject.
b.
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.
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 the
support, and check to be sure brake will hold load and that attach-
ments 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 hand chain pulls listed (Fig. 2)
WARNING!
To reduce the risk of injury, carefully check unit for
external damage prior to installation. Do not oper-
ate a damaged or malfunctioning hoist. Do not
operate a hoist with a twisted, kinked or damaged
chain. Operating a unit with obvious external dam-
age may cause load to drop resulting in personal
injury and/or property damage.
WARNING!
To reduce the risk of injury, stop operating in the
lifting direction before 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. 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.
WARNING!
To reduce the risk of injury, do not lift people or loads
over people.
Do not lift more than the rated load.
Do not lift at an angle.
Do not use load chain as a sling.
Fig. 1
WARNING!
To reduce the risk of injury, do not exceed the hand
chain pulls specified in Fig. 2. Exceeding the rated
capacity of the hoist may cause load to drop result-
ing in personal injury and/or property damage.
