1.
Make sure the workpiece is suitable for magnetic adhesion and that both the surface of the workpiece and
the magnetic base of the drill are clean and free of dirt, grease and debris.
2.
Secure the magnetic drill to the unit to workpiece with safety chain provided.
3.
Position the drill by sliding it and gently feeding the arbor so that pilot pin is in contact with the centre of the
hole you need to cut.
4.
Activate the magnet by pressing the magnet button to the
ON
position.
5.
Turn the Feed Handle, raising the annular cutter until the pilot pin is above the work surface.
6.
Open the cutting fluid valve.
8.
Make certain that the annular cutter is clear of the workpiece and turn the motor on by pressing the motor
button to the
ON
position.
9.
Feed the cutter slowly onto the workpiece. Carefully establish a cutting depth of about 1/16" before using
the full force of the drill on the cut by turning the feed handle to lower the arbor as required.
10.
Ease up on feed pressure as the cutter starts to break through the workpiece.
11.
When you have completed the cut, turn off the motor by pushing the motor button into the
STOP
position.
12.
Turn feed handles to raise the arbor away from the hole. This will cause the slug to fall free (if it hasn’t
already) so take care to ensure it does not fall in a way that can cause bodily harm to the operator or any other
persons in the vicinity.
13.
Turn the magnet
OFF
by pushing the magnet button to the
OFF
position. As the magnet de-activates the
base should lift up off the work surface.
14.
Disconnect the equipment from the power source.
15.
Remove any chips or debris from the cutter and the magnet wearing a pair of protective working gloves
and a set of pliers to protect your hands from sharp materials.
16.
Disconnect the safety chain and carefully remove the drill to complete the procedure.
