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.

Unpacking
Open carton and check for shipping damage.
Report any damage immediately to your distributor

Features and terminology
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.
Pre-Operation Inspection
Inspecting the Load Chain
1. A chain stop must be attached to the second-
to-last link on the slack end of the chain. See
Figure 2.
Figure 2
Do not operate the hoist with a
twisted, kinked or damaged chain. Do not
splice the chain.
2. Check that the chain does not twist along its
length from hoist to hook. If twist is present on
units with multiple falls, the hook must be
passed back through the chain loop to remove
all twist in the chain.
3. 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 12
for measuring chain elongation.
4. Do not use a chain that is seriously rusted or
cracked.
5. Periodically apply a light coat of 30W 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.
The load chain supplied with
your JET lever hoist is designed,
manufactured, and tested for proper fit and
durability. If chain should ever need replacing,
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 lever hoist.
Never extend load chain by welding a second
piece to the original.

8
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 hook
opening.
•The vertical angle at the neck of the hook
reaches 10°(see Figure 3).
Figure 3
•Chemical corrosion or cracks on the hook.
•Excessive wear on the inside surface.
•The throat opening has enlarged. (See page 12
for the maximum allowable limits for the throat
opening.)
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.
Other Inspections
1. Check for appropriate clicking sounds: With
the selector lever in UP position, there will be a
clicking sound when the lever handle is rotated
in either direction. When the selector lever is in
DOWN position, there will be a clicking sound
only when the lever handle is ratcheted back
into position but not as the load is lowered. 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.
2. If the lever 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 braking mechanism. The brake
should not slip while using the hoist.
Operation
The JLH Mini 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:
1. Set the top hook securely.
2. 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
3. Rotate the handwheel clockwise while
simultaneously pulling down on the load chain.
The handwheel will snap back into place, re-
engaging the gear.
4. Move selector switch to the UP position.
Ratchet the lever to raise or pull the load. Do
not overload the lever hoist.

9
Do not touch the handwheel
while lifting or lowering. Do not operate
freewheel mode while there is a load on the
hoist.
5. To release or lower the load, turn selector
switch on the handle to the DOWN position
and ratchet the handle.
NOTE: If the chain is pulled too suddenly in free-
wheel mode, the brake may set preventing further
pulling. Re-set the hoist by repeating step number
3 above, and then set the hoist back into freewheel
mode to continue the operation.
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.
Precautions
•During lifting operations, do not stand under
the load.
•Do not use any extension on the lever handle.
Do not use your foot to apply pressure to the
lever handle.
•Prevent the chain from dragging over sharp
edges or corners. This will cause links to
weaken, bend, or break.
•When connecting to a wire rope sling, the lever
hoist must be applied along a straight line
parallel to the surface on which it is resting.
See Figure 6.
Figure 6
•When lifting loads, hook the load with slings.
Do not use the lever hoist chain as a sling
(Figure 7).
•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.
Figure 7
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 30W 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.
