Operating Instructions

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this

manual including all text under subheadings therein before set up or use of this product.

Work Piece and Work Area Set Up

1. Designate a work area that is clean and well-lit.

The work area must not allow access by children

or pets to prevent distraction and injury.

2. When forming large pieces, use work horses

(sold separately) or other supports to help

maneuver the workpiece while forming.

General Operating Instructions

To learn how the metal handles, and how much

pressure to use with the tool, practice using the

Shrinker/Stretchers on a piece of scrap metal before

forming your workpiece. Use a scrap that is the same

type of metal and hardness as your workpiece.

Note: If bending a flange as shown below, first form the

workpiece′s 90° angle using a Sheet Metal Brake (sold

separately), creating a maximum flange depth of 1".

Figure 2 - Shrinking

Figure 3 - Stretching

1. Make a cardboard or wire template of the desired

finished size and shape of the workpiece.

2. Working with the leading edge first, insert

the workpiece halfway into the jaws.

3. Press firmly on the handle or foot pedal and move

the metal back and forth to form the workpiece.

The amount of pressure used with the handle

determines the amount of bending achieved.

4. Remove the workpiece often and check

against the template, continuing until

the desired shape is achieved.

Note: Bunching or pocketing that typically occurs

when shrinking can be hammered out.

Note: The jaws of the tools are ″toothed″ to better grip

the workpiece. These teeth leave slight markings which

can be removed with an abrasive cloth or wheel.

TO PREVENT INJURY FROM TOOL FAILURE:

Do not use damaged equipment. If abnormal noise or vibration

occurs, have the problem corrected before further use.

Cleaning, Maintenance, and Lubrication

1. BEFORE EACH USE, inspect the general

condition of the tool. Check for loose

hardware, misalignment or binding of moving

parts, cracked or broken parts, and any other

condition that may affect its safe operation.

2. When not in use, lightly oil the jaws with

machine oil to prevent corrosion.

need to be replaced in the same way.

d. There is a small Jaw opposite a large Jaw, top

and bottom. Clean the Jaws with cleaning fluid

and a bristle brush (sold separately). Do not

use a wire brush or a wire wheel. Brush in the

same direction as the teeth, with the grooves.

e. Clean the V-Blocks (10, 13, 17,

20) in the same way.
