PREPARATION
1. Insertion of pilot pin
The pilot pin is used to both center the cutter and to eject the slug on completion of the cut. It
has a flat side to allow the coolant to run down to reach the center of the cut where the heat is
greatest. Slide the pin through the hole in the center of the cutter shank.
2. Fitting the cutter
Lay the machine on its side, ensuring the set screws are accessible. Loosen both screws to
permit shank of the cutter to slide home in the arbor with the two flats aligned with the set
screws. Tighten the set screws in turn until the cutter is locked. Do not over-tighten the screws.
If a pilot pin is used, ensure that it slides freely in the cutter.
3. Clean any dirt or swarf from the base of the magnet and the workpiece with a gloved hand.
Mark the position of the hole by a center-punch. Place unit in correct position for drilling.
4. Place unit in correct position for drilling with the pilot over the center-punch. The magnet will
hold on all ferrous materials from a minimum of 6 mm (1/4") thickness.
5. Attach safety chain by looping it through the handle of the unit and around the workpiece or
other suitable anchor point, take up any slack in the chain and clip the hook through a
convenient link in the free end of the chain.
6. Check the air connection with a suitable supply (6 bar/90PSI, 64 SCFM/1,8 m
3
/min)
7. Connect the free end of the lubrication hose to the adapter of the motor.
DRILLING
1. Activate the magnet using the control lever.
2. Check magnet is holding to workpiece. Recheck the pilot is still centered on the hole position –
activating the magnet can sometimes cause the unit to move slightly from the center mark,
reposition if necessary.
3. Using the pressurized oil bottle add oil to the workpiece. Ensure only the correct cutting oil is
used, it has been formulated to speed cutting and enhance tool life.
4. Start the motor. Motor will not run unless magnet is activated. If for any reason the airflow is
interrupted, the switching system will leave the magnet on. The unit will switch itself to a drill off
position and will need to be switched back to drilling when the supply is re-connected.
5. Advance the cutter to the workpiece using light pressure until the cutter has broken the surface,
then increase the pressure until the motor is loaded and maintain even pressure right through
the cut. Too much pressure will not speed the cut, it will reduce the life of the cutter and may
cause damage to the motor. If the turnings become blue add more oil. At the end of the cut the
slug will be ejected, check before commencing the next hole. Make sure that no swarf collects
inside the cutter.
6. Stop motor, switch off magnet.
