CAUTION:
This manual is provided by Sumner covering the safe operation

and constructed to provide consistent, long-term operation if
used in accordance with instructions set forth in this manual.
The LH Series hoists are all steel construction with a powder coat
finish and have a completely enclosed Weston-type automatic
brake system.

ANSI/ASME B30.21 and HST-3 standards.

• Do not operate hoist unless load is centered between top and
bottom hooks.
• On hoists with the overload warning lever, do not use this device
to measure load weight.
• Always take time to study the job to be performed and choose
the safest method. Do not place yourself or other people in an
unsafe position.
• Always maintain your balance and firm footing when operating
the lever hoist.
• Leave all internal maintenance and inspections to a qualified
Sumner Service Center.
• Do not attempt to lengthen or repair load chain. Replace chain
with factory replacement chain only. Do not use any other type of
chain.
• If welding near the hoist, do not allow the chain or hook to be
touched by a live electrode. Prevent weld splatter upon the chain.
• Never use the hoist if either hook is stretched, deformed, or has
a broken or missing safety latch. Always replace the safety latch
and/or the hook before placing the hoist back in service.
• Be sure supporting structures and load-attaching devices used
in conjunction with this lever hoist provide an adequate safety
factor to handle the rated load plus the weight of the equipment. If
in doubt, consult a qualified structural engineer.
• Keep visitors a safe distance from the work area. Keep children
away.
• Understand and follow all procedures as set forth in American
National Standards titled “Performance Standard for Manually
Lever Operated Chain Hoists,” ANSI/ASME HST-3; and “Manually
Lever Operated Hoists,” ANSI/ASME B30.21. These standards are
available through the American Society of Mechanical Engineers
at www.asme.org.
