Use and Care Manual

9
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.
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).
• 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.
