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
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).

3. Rotate
the
handwheel
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.
