Milwaukee Tool 9687-20 - Manual (Page 5)

1. Attach the lower hook to the load.
2. To take up the slack load chain, follow the instructions
under “Free Chaining”.
NOTE: The load chain must feed into the chain guide roller
properly. A twisted chain may become damaged in the
liftwheel and cause chain breakage.
When operating in limited spaces, use attachments or
slings to prevent the frame and lever from being obstructed.
3. To lift or tension a load, set the directional lever to the
“LOAD” position and move the lever up and down
repeatedly.
4. To lower or loosen a load, set the directional lever to the
“UNLOAD” position and move the lever up and down
repeatedly.
RECOMMENDED PROCEDURES
1. The hoist must be kept clean to assure proper operation.
Before use, check to be sure the load chain is clean, that
there is no foreign material in the liftwheel area and that
the lever operates freely.
2. 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 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.
3. 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 upper hook to
lower hook.
4. When lifting, raise the load only enough to clear the floor
or the support, and check to be sure brake will 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.
5. Do not load beyond the rated capacity of the hoist. Rated
capacity can be achieved with noted force on lever (See
Figure 3). Any greater pull is an indication of either an
overload or an incorrectly maintained unit.
NOTE: Since force on the lever can easily be applied by one
person, under no circumstances should more than one person
operate the lever hoist. Overloading can cause immediate
failure of some load carrying parts or result in damage causing
future failure at less than rated capacity. When in doubt, use
the next larger capacity MILWAUKEE hoist.
6. 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.
7. Do not move a load over the heads of other personnel.
Warn personnel of your intention to move a load into their
area. Stand clear of all loads.
8. Do not leave a suspended load unattended.
9. Do not take up the load chain to the point where the chain
stop or lower hook block becomes jammed against the
frame.
10. Do not hold load chain while operating the hoist. Should
the hoist not operate properly, serious injury may occur.
11. Read warnings and instructions on the lever, frame and/or
warning tubes before each use.
12. Do not run the lower hook block into the hoist frame.
Frame and/or chain guide damage may result.
13. Do not operate hoist with other than manual power.
14. Do not use an extension on the lever.
15. Do not use this or any other materials handling equipment
for lifting people.
16. Do not allow the load to bear against the hook latch. The
latch is to prevent detachment of load under slack chain
conditions only.
17. When there is a load on the hoist, do not pull or turn the
free chaining knob. Doing this will allow the load to be
released in a sudden and uncontrolled manner and may
cause injury to you and/or property damage.
5
Do not use an extension on the lever. Exceeding the
rated lever pull or using an extension to lift or pull a
load will overload the hoist.
To reduce the risk of injury, do not exceed rated
capacity of the hoist. Doing this may cause the load to
drop resulting in personal injury and/or property
damage.
Malfunctioning of unit, rigging slip or loss of footing
may cause user to slip and result in injury. To avoid
injury, always have a firm and secure footing when
using the MILWAUKEE Lever Hoist.
