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.

Technical data

Diamond coring machine
For details of the rated voltage, current, frequency and input power, please refer to the machine's
country-specific type identification plate.
When powered by a generator or transformer, the generator or transformer's power output must be at
least twice the rated input power shown on the rating plate of the machine. The operating voltage of the
transformer or generator must always be within +5% and -15% of the rated voltage of the machine.
Switching other power tools, machines or appliances on and off may cause undervoltage and / or
overvoltage peaks, resulting in damage to the machine or appliance. Never operate other power tools,
machines or appliances from the generator or transformer at the same time.
