    In addition, all of the machines meet the current "Ontario Hydro" electrical code for proper manufacture of the electrical circuits. Hydraulic System Design/Manufacture: Hydraulic components used in Piranha machines are approved by NFPA (National Fluid Power Association), and those approval numbers can be traced through the manufacturer's part numbers.

  • Page 12: Installation

    Foundation To maintain the accurate alignment built into the Piranha, and to prevent undue stress on the moving parts under a load, the Piranha should be placed on a stable base or floor adequately constructed to withstand the unit weight.

  • Page 13: Operating Instructions

    Operating Instructions The Piranha Ironworker comes pre-assembled and pre-wired, requiring only the addition of hydraulic fluid in the reservoir to the mark on the fill cap dipstick and a power source from a disconnect to the electrical enclosure box located inside the cabinet.
  • Page 14 Joystick Operation The ironworker is hand controlled by a five-position momentary joystick operator. When the joystick is released from any of the four positions, it will return to the neutral (center) position stopping machine movement instantly. The joysticks are located on top of the control box at each end of the machine.
  • Page 15 ▪ Completion of downward cycle is accomplished by depressing footswitch lever again. Machine movement is down until limit setting is met (reference Figure F4). ▪ Removing foot pressure from the switch entirely allows machine movement upward to limit setting, completing upstroke cycle (reference Figure F5). Piranha Ironworker P140...
  • Page 16 Footswitch Limit Switches The footswitch is used in conjunction with the upstroke and downstroke limit switches located on the machine side off the front control box only, see figure C. ▪ The front limit switch (closest to the punch end and the lower switch of the two switches) controls the downstroke limit.
