Operation - Jet JLH Series Operating Instructions And Parts Manual

Operation

The JLH 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. Place the selector switch on the handle in
the center neutral position, and pull out on
the handwheel (Figure 4). This will allow
"free-wheel" mode. Pull the load chain by
hand to position the bottom hook.
3. Correctly center the load on the bottom
hook (Figure 5).
dangerous to the operator, the lever hoist,
and the load.
• Never load the hook in front of the safety
latch (A, Figure 6).
• Never load the hook tip (B, Figure 6).
• Never load the hook off the centerline (C,
Figure 6).
• Never load the hook sideways (D, Figure
6).
4. Rotate the handwheel clockwise while
simultaneously pulling down on the load
chain, as shown in Figure 4. The handwheel
will snap back into place, re-engaging the
gear.
5. 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.
6. 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 4 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.
