3.4. Preparation
Before beginning, clean steel parts, especially the Weldon shank, from grease used to
preserve the machine for storage and transport.
Mount the annular cutter into the arbor in the manner described before.
Position the machine on a flat ferromagnetic surface (some types of stainless and acid-proof
steel do not conduct magnetic flux) with the thickness of at least 6 mm (0.23''). The
workpiece must be clean, without rust or paint that decrease the holding force of the
electromagnetic base.
Then, connect the drilling machine to the power outlet and enable the holding force of the
electromagnetic base by toggling the MAGNET switch to position 'I'.
Protect the machine using the safety strap to prevent possible injury if the machine loses
magnetic adhesion in case of a power loss. In order to do this, either mount the strap
through the opening in the machine body (Figure 7a, 7b) or catch the strap on the carrying
handle when working in horizontal position (Figure 7c). The strap must be tight, not twisted,
and must be replaced every single time the machine hangs on the strap as a result of coming
loose from steel.

Figure 7. Securing the drilling machine using the safety strap
When working in the position from Figure 7a, mount the cooling system bottle as described
before and fill it with a cutting fluid. Do not use pure water as the cutting fluid, however,
