1.2 inch water well drilling rig/electric drilling rig/home drilling artifact handheld dis
Before drilling the well, the water inlet on top of the disk + connect the water pipe + connect the submersible pump or sewage pump or mud pump. When drilling a well, you must ensure that there is a flow of water, through the water inlet, into the drill rod, before you can operate the well. The well drilling machine works on the principle of drilling a well while water enters the water inlet. Having a water flow into the hole where the well is drilled can flush the drilled sediment out from inside the borehole.

Instructions for use: 
Handheld small well drilling machine can only drill soil, not rock.
2 Drilling depth up to 80 meters, borehole diameter 50-200 mm.
3 Install the drill bit. After screwing the drill bit, the machine should be tested in no load to make sure whether the rotating direction of the drill bit 
is consistent with the calibrated direction and the radial runout meets the requirements of 
regulations.
4 Receive the goods, firstly run the machine for 4-5 minutes.
5 Drilling operation. First, turn on the water, the amount of water should be moderate, it is strictly prohibited to work without water.
6 When the drilling machine stops automatically in the process of jammed drilling, it should use manual method 
to eliminate the jammed drilling before starting the motor, and it is strictly prohibited to use the 
method to eliminate the jammed drilling by forcibly energizing the motor, otherwise the motor will be damaged.
7 When the drill bit is close to drilling through, the feeding pressure should be reduced, and after drilling through, the drill bit should be lifted out of the hole at , and then the machine should be shut down. Remove the double wings 
8 Hit the water and start dragging back, pay attention to the amount of water should be increased, to make the hole soil flow out.
9 If there is no mud coming out, lift the drill pipe upwards and then continue drilling.
10 Prohibit the rig from reversing when drilling.
11 To change the steering, wait until the gears have come to a complete stop before changing the steering.
