Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. The term "power tool"...
  • Page 9 attached to a rotating part of the power tool may result in personal injury. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts.

  • Page 11 Placing the hand on the machine may result in an electric shock in the event of a voltage leak or if the machine cuts its own power supply cable. Always ensure that the work piece is a minimum of 12mm (7/16 in.) thick. If it is not, then use a piece of steel plate at least 12mm thick and larger than the magnet, below the work piece, to supplement the magnetic adhesion.
  • Page 12 push the red collar of the connector and pull the tube out.) Cutting coolant fluid is always required when using annular cutters. Open tank cover and fill. Check coolant fluid level often. Keep coolant tap closed when not in use. Chip guard must be used.

  • Page 13: Operation-General

    CAUTION: ALWAYS ensure that the machine is fully stopped before attempting to change gears! NEVER change gears on a running machine! OPERATION-GENERAL WARNING: Always ensure that the magnet is adhered properly to the work piece before beginning drilling. NOTE: If mounting to a curved surface beam, mount the machine parallel to the curve in the work piece.
  • Page 14 bolts. Then an optional chuck adaptor arbor and chuck must be fitted. Follow the special instructions below to replace the arbor support bracket. (For 1 speed & 2 speed model only ). Arbor support bracket replacement Replace arbor support bracket and screw in the 3 hex head bolts finger tight only (ensure that the needle bearing is clean and adequately greased.) Replace the annular cutter arbor.

  • Page 15: Auto-Feed Operation

    POSITION RANGE 14~20mm 21~24mm 25~30mm AUTO-FEED OPERATION Always begin drilling manually (with the handles pointing out) as described above in “OPERATION-GENERAL”. Only after the cutter has begun cutting for a few seconds and has raised a chip should the auto feed be engaged. NOTE: Do not cut manually for more than 10 seconds before shifting into auto feed.
  • Page 16 WARNING: NEVER ATTEMPT TO DRILL MATERIAL THICKER THAN THE DEPTH CAPACITY OF THE CUTTER. If the cutter is allowed to “bottom out” the feed system may cause the magnet to lift (usually it will overload first).NOTE: In very light load conditions, such as when using very small cutters or drilling a very thin work piece, often the load drop will not be enough to signal the machine’s electronic control board to automatically stop.

  • Page 17: Operation

    OPERATION The operation instructions under “OPERATION-GENERAL” also apply to this machine. Please see the additional instructions specific to the 4-speed Morse taper model below: WARNING: NEVER operate 60mm (2-3/8 in.) or larger cutters unless the plate thickness is mini mum 20mm (13/16 in.) MAGNET LIFTING MAY RESULT. If the plate thickness is not enough, supplement the magnetic adhesion by adding a 10mm or thicker plate directly the magnet’s position under the work piece.

  • Page 18: Cutting Speeds

    NOTE: the left and right side gear selectors have a different engagement design: For The LEFT HAND SLIDER must ALWAYS ensure that the machine is FULLY STOPPED before attempting to change gears! NEVER change the Left hand slider gears on a running machine! For the RIGHT HAND SLIDER the gears select by engagement dogs, similar to a motorcycle transmission design.

  • Page 20: Maintenance

    Replace the annular cutter arbor and carefully tighten the bolts evenly to ensure proper alignment. WARNING: use extreme care to avoid contacting the rotating arbor shaft! Double check to ensure that there is no binding anywhere throughout the stroke. NOTE: A pilot hole may be necessary when drilling with larger twist drills. If a MT3 twist drill is used, it may not be necessary to remove the arbor support bracket.
  • Page 21 Ensure that the ventilation slots are clear so that motor can be cooled normally. Blow low-pressure compressed air through the ventilation slots with the motor running to keep motor clean. THE ARBOR SHAFT Keep the arbor shaft free of dirt and lightly grease as needed. If the arbor support bearing is noisy, it may be dirty or have a chip lodged in it.
  • Page 22 NOTE: A faulty magnet coil can also damage the rectifier, so whenever there is a magnet problem, BOTH the magnet coils and rectifier must be checked. WARNING: Never attempt to operate a magnetic drill with a faulty magnet! CHECKING THE MAGNET (qualified technicians only) If the magnet is not working well, it must be checked.
