Using the Jet 756018 Shrinker Stretcher is a breeze. First, place the sheet metal you want to work on in the appropriate position. Then, use the foot pedal to start the operation. This leaves your hands free to guide the panel and create the perfect compound curves. When using the optional jaws for aluminum materials, make sure they are properly installed. As for maintenance, regularly check the frame structure for any signs of wear. Wipe down the machine after each use to keep it clean. Also, check the rubber non - skid pad on the foot pedal and replace it if it shows excessive wear. Keep the storage area for the additional jaws clean and organized. When moving the machine around the shop using the mobile base, be careful not to hit anything. This will help ensure the long - term performance and durability of your Jet Shrinker Stretcher.
