• 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.

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.
