550 Shrinker / Stretcher
Installation / Operation / Maintenance
1. Secure the tool to the work bench. Two holes are drilled and tapped into the body of the tool to accept two 3/8 - 16 bolts.
It can also be mounted on a vise if portable on-the-job field use is desired. The more rigid you secure it, the easier it is to
use.
2. Try the tool using a sample piece of metal first to get the "feel" of it. .
3. When forming any metal, work the leading edge first. This "breaks down" the maximum resistance and permits easy and
accurate working thereafter.
4. Move the metal back and forth as you apply pressure to the handle until the desired radius is obtained. The control of
these tools lies in the pressure exerted in the handle as the metal is moved back and forth between the jaws.
5. The jaws of both tools are "toothed" so as to exert a better grip on the metal. These teeth leave slight markings
depending on the hardness of the metal and can quickly be removed with either abrasive cloth or wheel.
CAUTION TIPS:
1. Notice when you receive your tool that an insert is between the teeth. NEVER press without a separator between jaws:
ALWAYS insert metal pieces or other material divider between jaws when not in use.
2. Take handle out of fulcrum slot when not in use to avoid accidental press.
