Operation and maintenance manual for P 225

FOREWORD

The machine P 225 is a pendulum bench sawing machine designed for cutting metals.
Operation is manual: after turning on the electrical power supply to the machine and clamping the workpiece in the vice,
the operator starts the blade by pressing the microswitch located on the control lever; he then moves the head downwards
in order to cut the material; after completing the cut, the cutting head returns to position ready for a new cutting cycle.
