SUMNER PIPE JACKS8

Proper Operation:

1. Sumner offers two different jack heights (hi and lo),

that allow welders to work at a comfortable height,

depending upon the diamter of the pipe or load.

Based on the size of the material to be welded,

select the correct jack for the job (see page 8 on

jack height).

Correct Jack Height

Operator work level is at

comfortable position.

Incorrect Jack Height

Work too low for operator

can result in back injury.

IMPORTANT Inspect jack prior to each use to

ensure legs are free of bends,

breaks or metal deformation and

that spanner nut rotates freely.
