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, using emulsions formed from mixing water and drilling oil is also

satisfactory. To check the operation of the cooling system, slightly loosen the bottle

cap, open the valve using the lever, and initially apply pressure on the pilot pin by

rotating the spoke handles counterclockwise. The fluid should fill the system and

should begin flowing from the inside of the cutter.

Enter into manual feed mode by positioning the spoke handles as shown in Figure 8a,

and

rotate them counterclockwise to place the tip of the pilot pin above the drilling

3. STARTUP AND OPERATION

3.1. Mounting and operating the annular cutter

Unplug the power cord from the power outlet and raise the motor by rotating the

spoke handles clockwise (1, Figure 3). Insert the proper pilot pin into the annular

cutter (2), then wear protective gloves and place the cutter into the arbor (3) in such

a way to align the flats 4 with the set screws 5. Finally, tighten both set screws with

the supplied 4 mm hex wrench. To dismount the cutter, proceed in reverse order.

All safety precautions must be closely observed.

Figure 4 shows how annular cutters operate. As the cutter penetrates the workpiece,

the pilot pin recesses into the arbor and tightens the spring. As a result, after the cutter

goes through the entire thickness, the slug core is expelled from the cutter.

Annular cutters are designed to establish only through holes shown in Figure 5.

During establishing incomplete through holes the pilot pin must not be used.

3.3. Control system of the electromagnetic base holding force

The PRO 35 AUTO drilling machine incorporates a holding force control system to monitor the adhesion force of the electromagnetic base to the surface. The force value depends on several factors; such as type, thickness, atness, and roughness of the surface, presence of paint, rust or other contaminants, supply voltage uctuations, and the wear of the electromagnetic base bottom. With the motor off, the base provides a fraction of the maximum holding force. Once the motor is started, the holding force rises to the maximum. If the holding force falls below a safe operating value, the control system will not allow the machine to operate. Additionally, the system will prevent the startup of the motor if the machine is placed on a surface thinner than 6 mm (0.23’’) as such thickness does not provide sufcient holding force. In such case, the adhesion force will be only about 25 % of the force attained on a standard 22 mm (0.87’’) at plate. If the motor does not continue operation after the green MOTOR button is pushed and released, it means that the control system is operating properly and preventing further drilling because of too low adhesion force. Always ensure the entire surface of the magnet base is in contact with the steel workpiece.

thickness does not provide sufficient holding force. In such case, the adhesion force

will be

only about 25 % of the force attained on a standard 22 mm (0.87’’) flat plate.

If the motor does not continue operation after the green MOTOR button is

pushed and released, it means that the control circuit is operating properly and

preventing further drilling because of too low adhesion force.

3.4. Preparing

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. Never insert the strap into

the buckle from the front (Figure 7d).

thickness does not provide sufficient holding force. In such case, the adhesion force

will be only about 25 % of the force attained on a standard 22 mm (0.87’’) flat plate.
