1. Read and understand the entire owner’s
manual before attempting operation. Failure to
comply with instructions and warnings may
cause serious injury.
2. This lever 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 lever hoist, do
not use until proper training and knowledge
have been obtained.
3. Do not use this lever 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.
4. Do not use lever hoist to lift, support or
transport people; or to lift or support loads over
people.
5. Do not exceed the rated capacity of the hoist.
6. Do not attempt to extend the lever handle
using a “cheater pipe” or any other such
device.
7. Do not strike the lever handle with a hammer
or any other object.
8. Do not use the chain as a sling. This may
cause damage to the chain.
9. Always inspect the lever hoist for damage prior
to use. If hoist is damaged, do not use until it
has been repaired or replaced.
10. Do not use more than one lever hoist to lift or
move a load. If this is unavoidable, each hoist
must have the same capacity as the load to be
moved.
11. Never allow chain to “set” over sharp edges.
All pulls or lifts must be made with straight
chain that is free of obstacles.
12. If the lever handle is difficult to operate, then
the load exceeds the capacity of the hoist.
Reduce load or select a hoist of larger
capacity.
13. Do not use hoist if the chain is twisted, kinked
or damaged.
14. Do not operate hoist unless load is centered
between top and bottom hooks.
15. On hoists with the overload warning lever, do
not use this device to measure load weight.
16. 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.
17. Always maintain your balance and firm footing
when operating the lever hoist.
18. Leave all internal maintenance and inspections
to a qualified JET Service Center.
19. Do not attempt to lengthen or repair load
chain. Replace chain with factory replacement
chain only. Do not use any other type of chain.
20. 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.
21. 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.
22. Be sure supporting structures and loadattaching devices used in conjunction with this
lever hoist provide an adequate safety factor to
handle the rated load plus the weight of the
equipment. If in doubt, consult a qualified
structural engineer.
23. Keep visitors a safe distance from the work
area. Keep children away.
24. Understand and follow all procedures as set
forth in American National Standards titled
“Performance Standard for Manually Lever
Operated Chain Hoists,” ANSI/ASME HST-3;
and “Manually Lever Operated Hoists,”
ANSI/ASME B30.21. These standards are
available through the American Society of

7.0 Installation
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 lever hoist. Supporting structures
(such as I-Beams, etc.) should be installed by
properly licensed professional installers.
8.0 Initial inspection
8.1 Inspecting the chain
•A chain stop must be attached to the
second-to-last link on the slack end of the
chain. See Figure 2 for an example.
Do not operate the hoist w ith a
twisted, kinked or damaged chain. Do not splice
the chain.
•Check that the chain does not twist along
its length from hoist to hook.
•Replace the chain if links are stretched too
long or seriously worn on the surface,
especially at the points where links contact
each other. See “Allowable Limits” on page
11 for measuring chain elongation.
•Do not use a chain that is seriously rusted
or cracked.
•Periodically apply a light coat of 30-weight
oil to the chain. This will create easier
operation and prolong the chain’s life. For
optimum results, clean the chain with an
acid-free solution before oiling.
•Never extend load chain by welding a
second piece to the original.
your JET lever hoist is des igned, man ufac tured,
and tested for proper fit a nd durability. If chain
should ever need replacing, for your ow n safet y
use factory replacement chain only. Use of
other than factory replacement chain may
cause serious injury and/or damage t o the l ever
hoist.
8.2 Inspecting hooks
It is important to check top and bottom hooks for
proper opening and other signs of deformation or
damage. Replace a hook immediately if any of the
following problems are identified:
•The safety latch no longer contacts the
Features and Terminology
hook opening.
Figure 1
Figure 2
The load chain supplied with
7
•The vertical angle at the neck of the hook
reaches 10° (see Figure 3).
• Chemical corrosion or cracks on the hook.
• Excessive wear on the inside surface.
• The throat opening has enlarged. (See
page 11 for the maximum allowable limits
for the throat opening.)
Figure 3
Do not attempt repair of a hook
by heat treating, bending or attaching anything
by welding. Such procedures will weaken and
may cause failure of the hook.
8.3 Other inspections
•With the lever in the up position, while pulling
down on the chain or with a load connected,
check for a clicking sound when the handle is
rotated in a clockwise direction. If these sounds
are not present, or if irregular clicking noises
develop, do not use the hoist – have it
inspected and repaired by an authorized
service center.
•With the lever in the up position, check free
play in handle rotation. Free play is measured
by the distance the handle travels before
resistance or gearing is felt. If free play has
reached 3/4 of a turn, brake discs are worn and
should be replaced by a JET authorized
service center.
•The brake mechanism must be kept clean and
free from dirt, water, and oil. Never allow oil to
penetrate the braking mechanism. The brake
should not slip while using the hoist.
•If the lever hoist has not been used for an
extended period of time, check for proper
operation before putting into service.
•Always keep your hoist clean and store in a
clean, dry location.
9.0 Operation
The JLP Lever Hoist may be used either in vertical
position as a hoist; or in angled or horizontal
position as a puller. Below is the general procedure
for operating the hoist:
• Set the top hook securely.
• Correctly center the load on the bottom hook
(Figure 4). Incorrect loading is dangerous to
the operator, the lever hoist, and the load.
•Never load the hook in front of the safety latch
(A, Figure 5).
• Never load the hook tip (B, Figure 5).
• Never load the hook off the centerline (C,
Figure 5).
•Never load the hook sideways (D, Figure 5).
Figure 4
Figure 5
8
•
Place the selector switch on the handle in the
center neutral position (Figure 6). Then grasp
ring behind handwheel with one hand and
rotate handwheel clockwise with other hand.
This will allow free-wheel mode. (NOTE: Chain
will only free-wheel when there is no load.)
Take up slack by pulling on loose or free end of
chain, or by turning handwheel.
•
When finished with freewheel mode, rotate
handwheel counterclockwise to re-engage
lifting and lowering modes.
Figure 6
•
Move selector switch to the UP position.
Ratchet the lever to raise or pull the load. Do
not overload the lever hoist.
•
To release or lower the load, turn selector
switch on the handle to the DOWN position
and ratchet the handle.
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.
10.0 Precautions
•
During pulling operations, the operator
should stand near the side of the top hook
on the opposite side from the lever. If the
hand should slip off the lever, the lever will
spring back away from the operator.
•
During lifting operations, do not stand under
the load.
•
Do not use an extension on the lever (Figure
7).
•
Do not use a foot to apply pressure to the
lever (Figure 8).
•
Prevent the chain from dragging over sharp
edges or corners. These will cause links to
weaken, bend, or break, (Figure 9).
9
•
When using a wire rope sling, the puller
must be applied along a straight line parallel
to the surface on which it is resting (Figure
10).
Figure 7
Figure 8
Figure 9
Figure 10
•When lifting loads, hook the load with slings.
Do not use the lever hoist chain as a sling,
(Figure 11).
Figure 11
•Both ends of a sling or rope must be
completely on the inside of the safety latch
before pulling or lifting the load. Do not put
one end on the inside of the latch and leave
the other end on the hook end outside the
latch.
11.0 Point hooks
Point or “shipyard” hooks are available for your JET
lever hoist, in 1-1/2 ton and 3 ton load sizes. They
are available in both upper and lower hook styles.
Point hooks are used in the metal and ship building
industries, and are designed for positioning steel
plate and fixtures before welding.
12.0 Inspection and
maintenance
Read and follow ANSI Inspection and Maintenance
Instructions. Know the meaning of Frequent
Inspection, Periodic Inspection, Normal Service,
Heavy Service, and Severe Service. It is the
customer’s responsibility to understand and follow
all ANSI and JET inspection and maintenance
instructions.
The lever hoist should be stored in a clean, dry
environment. Clean and oil the hoist before
storage.
Hoists that are installed out-of-doors should be
covered or brought inside when not in use.
Periodically apply a light coat of 30 weight oil to the
load chain. Also lubricate the safety latches and the
bearings in the hooks.
Annually, the hoist should be disassembled,
inspected, and cleaned by trained and experienced
personnel only. Contact a JET authorized service
center by calling your dealer or visiting our web site
at jettools.com.

13.0 Wear limits
13.1 Load chain wear limits
Carefully inspect the entire load chain. As
illustrated in Figure 12, measure five consecutive
links with calipers to find the length, Compare the
results with the table in Figure 12. Check every
three feet and especially where excessive wear is
indicated. Any load chain that shows noticeable
deformation or heat influence must be replaced
with a new one.
Never extend load chain by
welding a second piece to the original
.
