Warning
1. Read and understand this entire manual before attempting assembly or operation.
2. Read and understand the warnings posted on the hoist and in this manual. Failure to comply with all
of these warnings may cause serious injury.
3. Replace the warning labels if they become obscured or removed.
4. Do not use this hoist for other than its intended use. If used for other purposes, WMH Tool Group
disclaims any real or implied warranty and holds itself harmless from any injury that may result from
that use.
5. Always wear approved safety glasses/face shields while using this hoist. Everyday eyeglasses only
have impact resistant lenses; they are not safety glasses.
6. Before operating this hoist, remove tie, rings, watches and other jewelry, and roll sleeves up past the
elbows. Remove all loose clothing and confine long hair. Non-slip footwear or anti-skid floor strips are
recommended. Do not wear gloves.
7. This hoist is designed and intended for use by properly trained and experienced personnel only. If
you are not familiar with the proper and safe operation of a hoist, do not use until proper training and
knowledge have been obtained.
8. Do not use to lift people or loads over people.
9. Do not exceed the rated capacity of the hoist.
10. Do not use hoist chain as a sling. This may cause damage to the chain.
11. Always inspect the hoist for damage prior to use. If hoist is damaged, do not use until it has been
repaired or replaced.
12. Do not use more than one hoist to lift or move a load. If this is unavoidable, each hoist must have the
same capacity as the load to be moved.
13. Never allow chain to “set” over sharp edges. All pulls or lifts must be made with straight chain that is
free of obstacles.
14. If the hoist is difficult to operate, then the load exceeds the capacity of the hoist. Select a hoist of
larger capacity.
15. Do not use a hoist if the chain is twisted, kinked or damaged.
16. Do not operate hoist unless load is centered between top and bottom hooks.
17. Always take time to study the job to be performed and choose the safest method. Do not place
yourself or other people in an unsafe position.
18. Leave all internal maintenance and inspections to a qualified JET repair station.
19. Replace chain with factory replacement chain only. Do not use any other type of chain.
20. Never use the hoist if either hook is stretched, deformed, or has a broken or missing safety latch.
Always replace the safety latch and/or the hook before placing the hoist back in service.
21. Provide for adequate space surrounding work area and non-glare, overhead lighting.
22. Keep the floor around the machine clean and free of scrap material, oil and grease.
23. Keep visitors a safe distance from the work area. Keep children away.
24. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are
careless acts that can result in serious injury.
25. Stand to one side of the load being lifted and make sure no one else is standing underneath when
lifting a load. Should a load slip, it will descend at a high rate of speed and can cause serious injuries
to anyone standing directly underneath.

26. Do not force a tool or attachment to do a job for which it was not designed. The right tool will do the
job better and safer.
27. Use recommended accessories; improper accessories may be hazardous.
28. Maintain tools with care. Follow instructions for lubricating the hoist and changing accessories.
29. Understand and follow all procedures as set forth in American National Standards titled Performance
Standard for Hand Chain Manually Operated Chain Hoists. ANSI/ASME HST-2. This standard is
available through the American Society of Mechanical Engineers, 345 East 47th St., NY, NY 10017

Using the Chain Hoist
Prior to Operation
1. Support for the hoist may be hook, clevis pin,
trolley, or beam clamp. Whatever method of
suspension is chosen, the support components
must be rated equal to, or greater than the
capacity of the chain hoist.
2. If the chain hoist has not been used for an
extended period of time, check for proper
operation before putting into service.
3. The brake mechanism must be kept clean and
free from dirt, water, and oil. Never allow oil to
penetrate the brake mechanism. Always keep
your chain hoist clean and store in a clean, dry
location.
4. Although oiling the chain is not mandatory, a
light coat of 30-weight oil applied periodically to
the chain will create easier operation and
prolong the life of the chain.
5. Check the chain for damage and elongation.
Replace damaged chain before using the chain
hoist.
The load chain supplied with your JET chain hoist
is designed, manufactured, and tested for proper fit
and durability. Over a period of time, the chain may
need to be replaced. For your own safety, use
factory replacement chain only.
Use of other than factory
replacement chain may cause serious injury
and/or damage to the hoist.
6. The top and bottom hooks on your JET chain
hoist are designed to open to warn of an
overload. Both top and bottom hooks have
three indicator points cast into the hook. See
Figure 1. Measurements between all three
indicator points should be the same. If they are
not the same, the hook must be replaced.
7. It is important to check top and bottom hooks
for proper opening. If the safety latch no longer
contacts the hook opening, replace the hook.
Never side load the top or bottom hook; this
practice is dangerous and could lead to
serious injury.
8. If the vertical angle at the neck of the bottom or
top hook reaches 10°, replace the hook (see
Figure 2).

Figure 2
Hooking the Load
1. Secure the upper hook.
2. Place the bottom hook securely into the object
to be lifted.
3. Place ropes or chain in the center of the bottom
hook, making sure the safety latch is secure.
Never load the hook in front of the safety latch.
See Figure 3.
4. Avoid lifting one load with two hoists. If this is
unavoidable, apply equal weight to both hoists
and use hoists with the proper lift capacity.
Capacity of each hoist must be equal to the
total load to be lifted.
5. Check that the chain is not twisted at the
bottom hook. All welds should face the same
direction (Figure 4).
6. For hoists with two or more falls of chain, make
sure the bottom hook is not turned over. This
may cause the chain to twist.
Figure 3
Raising the Load
To raise the load, pull the right side of the hand
chain (A, Figure 5) clockwise.
To lower the load, pull the left side of the hand
chain (B, Figure 5) counterclockwise.
Important: Make sure the hoist has an adequate
length of load chain to raise or lower the load in a
safe manner. Do not attempt to lower the hoist
beyond its limit.
