How to repair the broken pneumatic drill?

The gas drill must first determine where it breaks. If only the drill chuck is damaged, it can be removed in the following ways. If the pneumatic drill is a forward and reverse pneumatic drill, there is a fixing screw in the drill chuck, which is usually tightened in the opposite way, so the reverse screw in the drill chuck must be removed first. When removing the drill chuck after removing the screw, you can use the positive and negative force of the pneumatic drill to grasp the drill chuck by hand (preferably wrap a rag) and press the pneumatic drill to reverse it to exit the drill chuck.

The other pneumatic drill has no reversing function, and the drill chuck and spindle are locked along the thread. This connection is getting tighter and tighter, and there is screw glue. To remove the chuck, it is necessary to first clamp a pneumatic batch with a drill chuck, and then directly punch it out in the opposite direction with a double-ring pneumatic batch with great torque.

If it's not the drill chuck, it needs professional maintenance personnel to repair it. The first is that even if some parts are found missing after dismantling, they can't be repaired if they are not on site. The second is that pneumatic tools have high requirements for sealing, and even if they are installed, there is a high possibility of air leakage or machine weakness.
