5. POWER AND AIR CONNECTION
5.1. Simple connection of air lines are made by quick connector. Socket 25 KEAK 13 (order number
FESTO 151776 - marking KD 1/4 - S, order number RECTUS 38044) is used as standard. Unithas
corresponding input Ê.
Input pressure must minimally be 1 bar (0,1 MPa) greater than output pressure set on regulator. The
manufacturer recommends addition of a shut-off valve so that it is possible to close the air supply.
5.2. After air connection check, set the air pressure on the dial of the regulator. It should be in the range
0.45-0.6 MPa. To correct it: pull the stopper Ë out. To increase the set pressure turn clockwise, to
decrease, turn counterclockwise. Tighten the stopper Ë again. The pressure for the cutting cylinders is
set to 0.4 MPa (4bar) from manufacturer by screw Ì and loosening the nut Î. If a material is
incorrectly cut, check the cutting steel and a pressure on the regulator Í.
Note: Set lower air pressure for short cutting steels and higher air pressure for long cutting steels.

5.3. Power supply must be 208 to 230 volts 1 phase, 50 or 60 hertz.
Receptacle plug must meet requirements of IEC standard
364-4-41, its circuit breaker must be minimal 10A with
characteristic C according to the EN 60947-2 (or 16A with
characteristic B). No other devices must not be connected to
the circuit breaker of the socket. The hand wheel Ñ must turn
counter clockwise.
The machine is equipped with a filters which contain
capacitors which generate an high frequency leakage current.
In order to prevent nuisance tripping, residual current
protection device must be protected against these high frequency currents: this is the case for
industrial residual current device (example „S“ type).
5.4. To add the LED lights - the provided warranty does not refer to the LED diodes.
