  • Page 6: Safety Instructions

    The Pentruder 3P8 HF-wire saw is intended to be used together with a Pentpak HF-power pack. The Pentruder 3P8 cannot be used with any other type of power pack. The Pentpak HF-power pack may only be used to power Pentruder HF-machines.

  • Page 7: General Safety Instructions

    Tractive. • A Pentruder machine used in the correct way is a safe and efficient tool. If the machine is used improperly this can expose the operator and other persons staying in the same area to extreme danger or even risk of fatal injuries.

  • Page 8: Safety Precautions At Site

    • The power or force applied on the wire in the 3P8 is higher than on any other commercially available electrically driven compact (non quarry type) wire saw. Therefore it is important to splice the wire carefully.
  • Page 9 The power pack should preferably only be operated when it is put on its back with the warning triangle upwards. • Connect the HF-power pack only to Pentruder HF-wall saws, Pentruder HF-Wire Saws, HF-drill motors or any Pentruder equipment which has been manufactured or approved by Tractive AB.

  • Page 11: Preparations And Mounting

    Try to plan the set-up so that satellite wheels are not needed. • The 3P8 can most often be mounted directly on the cut object. If this is possible, it is called a direct cut. A direct cut is preferable as extra satellite pulleys steal power.
