1. Select the location of the wellhead, dig a circular well with the same diameter as the drill bit and a depth roughly equal to the drill bit according to the requirements, and place the drill bit in it.

2. Align the center of the rotary table hole of the drilling machine with the center of the excavated circular well, and place the drilling machine. Hang a rope from the pulley above the mast and tie an object, adjust the support legs to align the rope with the center of the rotary table hole, and place a large wooden block under the support legs to make them stable and reliable.
