• thickness of work piece is at least 10mm (3/8”)
• surface of steel under the magnet is flat
• wipe, brush or sand down clean surface where you intended to place the drilling machine,
so that you remove rust, paint, dirt etc. which would reduce adhesive power of the
electromagnetic base.
• Install drill bit, annular cutter or other tooling such as tapping head or reamer into the
machine before plugging it air supply. Then plug into air supply (see paragraph 2) and
position where you wish to drill. Place the machine so that the tool is over the centre of the
hole you intend to make and turn the magnetic base ON.
Prior to use always make sure that the machine is secured from falling down with
original chain
2.7 Cutting
• Select the right speed for the tool you intend to use (see the speeds chart in this manual).
Do not use water as the cutting fluid.
The coolant system is an integral part of the machine and should always be used.
Warning: The coolant system can only be used when drilling machine is in vertical
position. In other positions additional external source of coolant should be used, for
example: a pressure feed coolant bottle.
• Check working of cooling system. Open coolant reservoir’s tap and apply pressure on the
pilot by turning the feed handles counter clockwise. As the pilot pin starts to retract up into
the annular cutter, cutting fluid should start to run down cutters inner wall and onto the
workpiece. If there is no cutting fluid flowing down check if the tap is fully opened. It may
take a few seconds for cutting fluid to fill the whole system.
• Connect air pressure hose with feeding air of appropriate parameters (6 bar / 90 PSI,
1400 l/min).
• Position an axis of the spindle precisely above drilling point
• Switch on magnetic action using the MAGNET switch.
• Turn the motor on.
• Making a hole with an annular cutter should ideally be done in one pass. It makes
the cutter work better and easier to eject the slug after the hole is completed. If you
experience slugs getting stuck inside a cutter after hole is complete try to reduce pressure
on the cutter. Do not allow excessive swarf build up around the annular cutter and arbor.
WARNING: when the annular cutter goes through the material, the slug can be pushed
out often with considerable strength. Pay attention to avoid injury.
