mode the water is free to flow. Water from the water supply flows out
through the core bit. Manual mode is deactivated by pressing the Cut
Assist button.
After switching over from manual mode, Cut Assist is activated with full
power available. Pressing the Cut Assist button repeatedly switches the
unit to the medium power setting, then to the low power setting and fi-
nally back to full power. Cut Assist starts the cooling water flow only
when drilling begins and stops the water automatically when the end of
the drilling operation is detected. The manual mode button deactivates
Cut Assist.
