2. Lead the gas and water pipelines, lighting lines, etc. to the vicinity of the working surface for use.


3. According to the requirements of the design of holes, erect the pillars firmly. The upper and lower ends of the pillar should be padded with wooden boards. After installing the horizontal shaft and the snap ring on the pillar according to a certain height and direction, use the hand winch to lift the machine, fix it on the pillar at the required angle, and then adjust the hole of the drilling rig.

When the advancing work moves the rod reel to collide with the drill, a drill rod is drilled. To stop the operation of the motor and stop supplying air and water to the impactor, insert the fork into the drill pipe groove of the drill holder, make the motor reverse the slide plate and retreat, so that the joint is disconnected from the drill pipe, and then connect the second drill pipe, press Here you work continuously in a loop.
