(1) Install a hollow drill bit of proper diameter.

(2) Move the drill hole to the required working place, fix the drill hole with expansion screws, adjust the anchor screws to stabilize the drill, or fix the drilling and coring machine with a heavy base plate to prevent the machine from moving during drilling and coring.

(3) Connect the water source and check whether there is water flowing out.

(4) Start the generator and turn on the circuit switch.

(5) Rotate the handle to make the drill touch the cutting position slightly. When the drill is cut into about 10mm, press the handle to speed up the spinning speed.
