Cutting Techniques

  • Plunge cutting: Suitable only for soft materials like wood, aerated concrete, or gypsum plaster boards. Start at an angle and slowly move the saw to a vertical position.
  • Flush cutting: Use elastic bi-metal blades to cut objects near walls. Apply the blade directly to the wall and bend it slightly so the footplate rests against the wall.

Maintenance

Clean the machine casing regularly with a soft cloth, preferably after each use. Ensure ventilation openings are free of dust and dirt. Do not use solvents such as gasoline, alcohol, or ammonia, as these will damage synthetic components.

Practical help

Common problems

Blade seizes during operation

Switch off the machine immediately. Use a suitable tool to spread the gap and pull out the saw blade.

Machine does not start

Check if the battery is charged and properly inserted. Ensure the lock-off button is pressed before the on/off switch.

Excessive vibration

Check if the blade is sharp and undamaged. Use coolant or lubricant when sawing metal to reduce fluttering.

Before use

  • Charge the battery fully before first use.
  • Ensure the blade holder is free of debris.
  • Check that the saw blade is sharp and undamaged.
  • Secure the workpiece with clamps or a vice.
  • Wear eye protection, ear protection, and a dust mask.
  • Check the work area for hidden utility lines.
