General Operating Instructions The Shop Press can be used for a variety of functions including electric motor and armature repair, installation and removal of pressure fitted parts such as gears and bearings, and bending or straightening of metal. Care should be taken in set up and operation of the Shop Press to avoid damage or injury. To operate the Shop Press: 1. Use the Support Pins (19) to adjust the height of the Press Apron (12). Note: The Press Apron (12) should be in the highest position possible with the workpiece as close as possible to the ram of the Press Rod (24). 2. Place the item to press between the Arbor Plates (20). WARNING: Make sure there is no obstruction (such as a stray bolt or debris) under the Arbor Plates. Such items create an uneven surface which can cause the Arbor Plates to break under pressure. WARNING: When pressing two items together, the items must be lined up vertically. If not, one item may forcefully eject itself sideways from the unit. 3. SKU 37999 Using the Jack Handle (3), jack down the Jack Plate until the ram of the Jack Plate contacts your workpiece. Make sure if you are pressing two items together, that they are in vertical alignment. Continue to operate the Handle to press the work piece. For technical questions, please call 1-800-444-3353. Page 9 4. When the task is completed, be careful when releasing Jack pressure. For safety, remove the Handle, then use the Handle to slowly turn the Valve Release Screw on the Jack, allowing the Jack Plate to rise. User-Maintenance Instructions Procedures not specifically explained in this manual must be performed only by a qualified technician.
