FURTHER INSPECTIONS
It is important to check top and bottom hooks for proper opening
and other signs of deformation or damage. Replace a hook imme-
diately if any of t 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 (FIG 3).
• Chemical corrosion or cracks on the hook.
• Excessive wear on the inside surface.
• The throat opening has enlarged. See (FIG 13) for the maximum
allowable limits for the throat opening.
• A chain stop must be attached to the second-to-last link on the
slack end of the chain. See (FIG 1) for an example. Do not operate
the hoist with a twisted, kinked or damaged chain. Do not splice
the chain.
•Check that the chain does not twist along its length from hoist to hook.
• 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 page14 for measuring chain elongation.
• Do not use a chain that is seriously rusted or cracked.
• Periodically apply a light coat of 30-weight 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.
•Never extend load chain by welding a second piece to the original.
INSPECTING THE HOOK
• With the lever in the up position, while pulling down on the chain
or with a load connected, check for a clicking sound when the
handle is rotated in a clockwise direction. 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.
• With the lever in the up position, check free play in handle
rotation. Free play is measured by the distance the handle travels
before resistance or gearing is felt. If free play has reached 3/4 of
a turn, brake discs are worn and should be replaced by a Sumner
authorized service center.
• The brake mechanism must be kept clean and free from dirt,
water, and oil. Never allow oil to penetrate the braking mecha-
nism. The brake should not slip while using the hoist.
•If the lever hoist has not been used for an extended period,
check for proper operation before putting into service.
OPERATION
The LH 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:
•Set the top hook securely.
• Correctly center the load on the bottom hook (FIG 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, FIG 5).
• Never load the hook tip (B, FIG 5).
• Never load the hook off the centerline (C, FIG 5).
• Never load the hook sideways (D, FIG 5).
FIG 3
FIG 4 FIG 5
WARNING: Do not attempt repair of the hook by heat treating,
bending or attaching anything by welding. Doing so will weaken and
may cause failure of the hook.

1211
OPERATION
• Always keep your hoist clean and store in a clean, dry location.
Place the selector switch on the handle in the center neutral
position (FIG 6). This will allow free-wheel mode. Take up slack by
pulling on loose or free end of chain.
• When finished with freewheel mode (Neutral Position), switch
selector switch to UP or DOWN to re-engage lifting and lowering
modes.
• Move selector switch to the UP position. Ratchet the lever to
raise or pull the load. Do not overload the lever hoist.
• To release or lower the load, turn selector switch on the handle
to the DOWN position and ratchet the handle.
• During pulling operations, the operator should stand near the
side of the top hook on the opposite side from the lever. If the
hand should slip off the lever, the lever will spring back away from
the operator.
• During lifting operations, do not stand under the load.
• Do not use an extension on the lever (FIG 7).
• Do not use a foot to apply pressure to the lever (FIG 8).
• Prevent the chain from dragging over sharp edges or corners.
These will cause links to weaken, bend, or break, (FIG 9).
• When using a wire rope sling, the puller must be applied along a
straight line parallel to the surface on which it is resting (FIG 10).
• When lifting loads, hook the load with slings. Do not use the lever
hoist chain as a sling (FIG 11).
• 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.
PRECAUTIONS
FIG 6
FIG 7 FIG 8
FIG 9
FIG 10
FIG 11
CAUTION : 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.

• Carefully inspect the entire load chain. As illustrated in (FIG 12),
measure five consecutive links with calipers to find the length,
Compare the results with the table in (FIG 12). Check every three
feet and especially where excessive wear is indicated. Any load
chain that shows noticeable deformation or heat influence must be
replaced with a new one.
FIG 12
FIG 13
WARNING : Never heat treat the hook or attach anything to
the hook by welding.
INSPECTION
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
Sumner 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 30 weight 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
Sumner authorized service center by calling your dealer or visiting
our web site at www.sumner.com.
