3.11 Speed settings
The machine has two speeds: low speed for starting holes and high speed for normal drilling.
When the control switch is pressed only half way, only the low-speed hole-starting mode is active. The
water flow rate should also be set while the machine is running at this speed. Maximum drilling speed for the
selected speed setting will be reached when the control switch is pressed in all the way.
