3.
Use the pilot pin to position the machine and in the correct position, with the tip of the pilot
pin to meet the marked center of the hole.
4.
Switch on the magnet and verify that the drill is in the right position and that the machine is
pushed tight against the work piece.
5.
If your machine is equipped with a auto coolant system, put open the valve to release the oil.
If your machine does not have an auto coolant system, fill the holes of the spindle with oil.
6.
Switch the motor on at and allow it to run at the required speed.
7.
Turn the arms to start drilling. Apply only a slight pressure when the annular cutter touch the
metal. Do not push the annular cutter with force into the metal.
8.
Apply a regular pressure while drilling. The drilling performance does not improve by putting
more pressure on the tool. Too much pressure will overload the motor and your annular
cutter will be worn sooner.
A continuous, non-discoloured iron swarf is a sign of correct drilling speed and a well-
cooled, sharp cutter. Let the cutter do the job and give it time to cut the metal!!!
9.
Adjust the oil supply when necessary, if your drill does not have an auto coolant system, stop
drilling regularly, refill the holes of the spindle and continue drilling.
10.
Apply less pressure when the drill cuts through the material. The slug will be pushed out of
the cutter by the pilot pin.
11.
Turn the arms to put the motor in highest position and switch off the motor unit.
12.
Remove the burrs, metal chips and clean the cutter and surface without getting injuries.
Caution
: The metal piece drilled out can be sharp and very hot!!
