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 or seriously
worn on the surface, especially at the points where
links contact each other. Do not use a chain that is
seriously rusted or cracked.
4. 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 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.

OPERATION
Before initial operation of hoist:
1. Read and comply with all instructions and warnings
furnished with or attached to lever hoist.
2. Check lubricant.
3. Check operation of brake.
4. Check that chain is properly seated in sheaves and
that chain is not twisted, kinked, or damaged.
Before each shift:
1. Inspect hooks for nicks, gouges, cracks,
and signs of pulling apart or twisting.
2. Inspect hook latch for proper operation.
3. Check chain for kinks or twists.
4. Check operation of brake.
5. Replace warning label if missing or illegible.
Before operating:
1. Be certain all personnel are clear of the load to be
lifted and moved.
2. Make sure load will clear stock piles, machinery,
or other obstructions when hoisting and travelling
the load.
3. Eliminate any twists or kinks in the load chain.
JET Lever Hoists 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 3). 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 4).
• Never load the hook tip (B, Figure 4).
• Never load the hook off the centerline
(C, Figure 4).
• Never load the hook sideways (D, Figure 4)
Figure 3
.
Figure 4
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.
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 5.
Figure 5
• When lifting loads, hook the load with slings.
Do not use the lever hoist chain as a sling
(Figure 6).
• 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.

INSPECTION AND MAINTENANCE
Prior to initial use, all new, modified, and repaired hoists should be inspected in accordance with Table 2.
Thereafter, inspections should be conducted at intervals shown in Table 1; and items to be inspected are indicated
in Table 2 by F(Frequent) or P(Periodic).
Frequent inspections – Visual inspection by the operator or other authorized person. This inspection includes
listening for unusual sounds while the hoist is operated that may indicate deficiencies.
Periodic Inspections – Audible-visual inspection as for Frequent Inspections, with some disassembly to allow a
more detailed inspection if external conditions indicate needed.
Exceptions – Brakes require more than audible-visual inspection. Check daily by operating the lever hoist with and
without load, stopping at various positions to test holding power and amount of drift, if any occurs.

HOOKS
WARNING
1. Any hook that requires replacement because of excessive bends, twists, or throat opening indicates abuse or
overloading of the hoist. Therefore, other load-supporting components of the lever hoist should be inspected for
possible damage when such conditions are found.
2. Never repair hooks by welding or reshaping. Heat applied to the hook will alter the original heat treatment of the hook
material and reduce the strength of the hook.
3. Never weld handles or other attachments to the hook. Heat applied to the hook will alter the original heat treatment of
the hook material and reduce the strength of the hook.
HOOKS INSPECTION
Refers to ASME B30.10, Safety Standard for Hooks. Inspect hooks and measure hook throat opening at least once a
month. Between regular inspections check visually daily for deformation, distortion, twisting, damage, and missing or
damaged hook latches. Inspect as follows:
1. Measure hook opening at raised dots (Figure 7) to check for stretch. Raised dots provide a constant reference point
and eliminate measurement errors. Replace hook when measurement between dots reaches “Dimension A Replace
Hook” figures below.

Capacity
"A" Dimension
Normal (mm)
"A" Dimension
Replace Hook if ≥ (mm)
0.25 ton 35.5 37.3
0.50 ton 41 43.1
2. A bend or twist of the hook exceeding 10° from the plane of the unbent hook requires replacement of the hook.
3. A hook latch that is missing shall be replaced.
4. A hook latch that is inoperative shall be repaired or replaced.
5. A hook with a hook latch that does not close the throat opening of the hook shall be removed from service until the
latch is replaced or repaired.
6. Hooks having damage from chemicals, corrosion, or deformation shall be repaired or replaced.
Due to variations in the manufacturing process, the dimensions of a new hook are variable. For accurate record
keeping, we recommend users record measurement of Dimension A of the hook before use. Record this information
in the spaces above and calculate the replacement value by multiplying by 1.05 for Dimension A.

CHAIN
Inspect chain at least once a month. Between regular inspections, check visually daily for nicks, gouges, weld splatter,
corrosion, or distorted links. Inspect chain thoroughly if it does not feed smoothly over load sheaves. Inspect as follows:
1. Clean chain with solvent before inspection.
2. Test hoist with load and observe operation of chain over load sheaves.
