FAILURE TO OBSERVE THESE CAUTIONS CAN RESULT IN 

INJURY OR PROPERTY DAMAGE 

    CAUTION:

This manual is provided by Sumner covering the safe operation 

and maintenance procedures for the Sumner LH Series Lever 

Hoists/Pullers. This manual contains instructions on installation, 

safety precautions, general operating procedures, maintenance 

instructions and parts breakdown. This tool has been designed 

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.   

The LH series hoists are proof-tested and comply with OSHA, 

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

If there are any questions or comments, please contact either your 

local supplier or Sumner Manufacturing. Sumner can also be 

reached at our web site: www.sumner.com. 

The specifications in this manual were current at time of publica-

tion, but because of our policy of continuous improvement, 

Sumner reserves the right to change specifications at any time 

and without prior notice, without incurring obligations.

• 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.
