1.0 IMPORTANT SAFETY INSTRUCTIONS
WARNING – To reduce risk of injury:
1. Read and understand the entire owner’s
manual before attempting assembly or
operation.
2. Read and understand the warnings posted on
the tool and in this manual. Failure to comply
with all of these warnings may cause serious
injury and/or damage to property.
3. Replace the warning labels if they become
obscured or are missing.
4. Keep visitors a safe distance from the work
area. Keep children away.
5. Give your work undivided attention. Looking
around, carrying on a conversation and “horseplay” are careless acts that can result in
serious injury.
6. Provide for adequate space surrounding work
area and non-glare, overhead lighting.
7. This chain 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 chain hoist, do
not use until proper training and knowledge
have been obtained.
8. Do not use this chain hoist for other than its
intended use. If used for other purposes, JET
disclaims any real or implied warranty and
holds itself harmless from any injury that may
result from that use.
9. Do not use to lift people or loads over people.
10. Do not exceed the rated capacity of the chain
hoist.
11. Do not use more than hand power to pull the
hand chain.
12. Do not use the load chain as a sling; this may
cause damage to the chain.
13. Always inspect the chain hoist for damage
prior to use. If the chain hoist is damaged, do
not use until it has been repaired or replaced.
14. Do not use more than one chain hoist to lift or
move a load. If this is unavoidable, each chain
hoist must have the same capacity as the load
to be moved.
15. Never allow the load chain to “set” over sharp
edges. All lifts must be made with straight
chain that is free of obstacles.
16. If the hand chain is difficult to operate, then the
load exceeds the capacity of the chain hoist.
Select a chain hoist of larger capacity.
17. Do not use a chain hoist unless load is
centered between top and bottom hooks.
18. 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.
19. 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.
20. Leave all internal maintenance to a qualified
JET Service Center.
21. Replace the chain with factory replacement
chain only. Do not use any other type of chain.
22. If welding near the hoist, do not allow the chain
or hook to be touched by a live electrode.
Prevent weld splatter upon the chain.
23. Never use the chain 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 chain
hoist back into service.
24. 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; and “Overhead Hoists (Underhung),”
ANSI/ASME B30.16. These standards are
available through the American Society of
Mechanical Engineers, www.ASME.org

5.0 Using the Chain Hoist
5.1 Prior to Operation
1. Support f or 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 30W 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 c hain
hoist are designed to open to warn of an
overload. Both top and bottom hooks (1/2T to
5T models) have indicator points cast into the
hook. See Figure 1. The measurement
between indicator points must fall below the
limit shown in section 9.2, Table 3. If it
exceeds the limit, the hook must be replaced.
7. It is important to c heck 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
5.2 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.
Figure 1
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.
6
5. Check that the chain is not twisted at the
bottom hook. All welds should face the same
direction (Figure 4).
Figure 4
6. For hoists with two or more falls of chain, make
sure the bottom hook is not capsized (turned
over). This may cause the chain to twist.
5.3 Raising the Load
Figure 6
2. Using a hack saw, cut through upper part of
link at the weld.
3. Loosen the link, reposition link vertically at
edge of vise with the level of the cut above the
vise jaw (Figure 7).
To raise load, pull right side of hand chain (A,
Figure 5) so that wheel turns clockwise.
To lower load, pull left side of hand chain (B,
Figure 5) so that wheel turns counterclockwise.
Important: Make sure hoist has an adequate
length of load chain to raise or lower the load in a
safe manner. Do not attempt to lower hoist beyond
its limit.
Figure 5
6.0 Hand chain: Cutting
Figure 7
4. Tighten vise jaw.
5. Using an adjustable wrench, twist the link
horizontally from front to back. (Figure 8)
Open just far enough to insert (or remove) a
second chain link.
Figure 8
Note: Chain length is now ready to lengthen or
shorten.
6. Insert (or remove) the second end link at the
opening in the first end link.
7. Using an adjustable wrench, twist the link
horizontally until the link is in the original
closed position. See Figure 9.
and installing
To cut hand chain in order to lengthen or shorten:
1. Insert one link lengthwise into a vise (Figure
6). Be sure that the side opposite the weld lies
completely below surface of vise jaw (about
1/3 of a link). This prevents nicking or cutting
the lower part of the link.
Figure 9
7
Do not push the link inward
from the curved ends. This will distort the li nk.
Check that the link is closed and free of twist.
8. If installing entire new chain, insert end of
hand chain into groove at top of hand chain
wheel (see Figure 11). Rotate handwheel and
pull chain through.
9. Re-weld the link at the cut.
10. Grind off excess on weld so that it is smooth.
Do not operate the hois t with a
twisted, kinked or damaged load chain. Do not
splice the load chain. Check the chain for
excessive wear or stretch. Failure to comply
may cause serious injury.
7.0 Load chain: Removing
and installing
7.1 Load chain inspection
Over time, the load chain will wear or elongate.
This can cause damage to the hoist, breakage, or
non-engagement of the load sheave.
Do not operate the hois t with a
twisted, kinked or damaged load chain. Do not
splice load chain. Check the chain for
excessive wear or stretch. Failure to comply
may cause serious injury.
To inspect the load chain for wear:
1. Test the hois t under load in both the lifting and
lowering directions, observing the operation of
chain and sprockets. Chain should feed
smoothly into and away from the sprockets.
2. If the chain binds, jumps, or is noisy, make
sure it is clean and properly lubricated. If the
trouble persists, inspect the chain and mating
parts for wear, distortion, or other damage.
3. Clean the chain before inspection. Examine for
gouges, nicks, weld splatter, corrosion, and
distorted links. Slacken the chain and move
adjacent links to one side, looking for wear at
the contact points. If you see wear or suspect
stretching, measure the chain as explained in
section 10.1. If chain matches or exceeds the
limit shown in Table 2, replace the load chain
before using the hoist.
7.2 Load chain removal (all models)
Remove old load chain as follows while referring to
Figure 10:
1. Remove split pin (A) and pin stopper (B) on
the chain anchor C), allowing the end of the
load chain to fall free.
2. Pull the hand chain (Figure 5) until load chain
is completely removed from gear assembly.
Figure 10
7.3 Attaching load chain to load
chain sprocket (all models)
Install new load chain onto load chain sprocket as
follows, referring to Figure 11:
1. Position the load chain sprocket (E) by rotating
hand chain wheel (F) so that the wide and
narrow grooves show.
2. Insert the load chain into the sprocket grooves
so that chain will wind up and back over the
sprocket. Welds must face away from the
sprocket.
3. Rotate hand chain wheel so that load chain
falls six to eight inches at back of sprocket.
Do not add to the load chain.
Replace entire chain. Failure to comply may
cause serious injury.
Figure 11

Referring back to Figure 10:
4. Insert one end of chain link (D) into chain
anchor (C).
5. Insert pin stopper (B) through chain anchor (C)
and chain link (D) and secure with split pin (A).
Continue with section 8.4, proceeding to the
section that applies to your hoist.
7.4
Completing load chain installation
The following procedure assumes that the load
chain has been attac hed to the chain anchor and
fed through the load chain sprocket as described in
the previous section. This procedure will complete
the load chain and bottom hook installation.
