5. Operating Instructions

5.1 General Operation

Before starting, ensure your workpiece is stable and marked with the desired cutting line. Plug the jigsaw into a suitable power outlet (240 Volts recommended).

• Place the base plate of the jigsaw flat on the workpiece, ensuring the blade is clear of the material.
• Start the jigsaw by pressing the trigger switch. Allow the blade to reach full speed before beginning the cut.
• Guide the jigsaw along the marked cutting line with steady, even pressure. Do not force the tool; let the blade do the work.
• The integrated dust blower will help keep your cutting line visible.
• For straight cuts, consider using a guide rail or straight edge. For curved cuts, guide the tool smoothly along the curve.
• When finished, release the trigger switch and wait for the blade to stop completely before lifting the tool from the workpiece.
