Page 6: Definition Of Terms / Model Identification
INTRODUCTION Your new Bender is a “Press-Style” Bender that is capable of bending, flaring and swaging Tubing up to 3 inches in diameter. The thickness of the Tubing plays an important part in bending. (See Specifications for recommended Tubing allowances.) The front of the Bender is where all the bending is performed. -
Page 7: Installing The Electrical Plug
CONTROL FEATURES BB or BLUE-BULLET Models - A Hydraulic Control Valve is located at the front of the machine at knee height that allows the operators to manually control the machine with their leg. A Degree Plate is mounted up front that shows proper bend depths. -

Cycle the Cylinders to their full extent at least five times. WARNING! 8. The Hydraulic System will self-bleed any trapped air Prior to operation, you must add approximately 4.5 in the system after approximately 10 minutes of gallons (17 liters) of Anti-Foaming Hydraulic Fluid... - Page 9 Half Shoe Three-Quarter Shoe BACK SHOES - Back Shoes, which are commonly referred to as Wiper Dies come in pairs and are used together with the Radius Dies during the bending process. CAUTION! These Dies play an important part as their primary pur- pose is to form the outside radius of the bend.
