The gun head screw has been reversed, this is the reason for the air pressure, air pressure is lower than the minimum 0.5 bar or the lack of lubrication of the seals, will cause this failure, eliminate the cause is very simple, adjust the air pressure and the motor seals with lubricating grease will be able to.

Rivet nut folding improper, or pull rivet nut is not tight, this is incorrect stroke, air pressure is small, and hydraulic oil is not enough, there is another is the workpiece plate thickness does not meet, here we need to adjust the stroke, adjust the air pressure and fill the hydraulic oil, check the rivet nut, and check the thickness of the rivet nut and riveted version.

Pulling screw positive rotation is due to the motor tie rod hexagonal wear, motor seal wear caused by the solution we just need to replace it.

The rivet nut cannot be set into the rivet nut gun screw, this is due to the distance between the spring seat and the reset do is too small, the pneumatic motor blockage caused, we need to readjust the spacing, dismantle the motor for cleaning and lubrication can be solved.

The trigger of the rivet nut gun is not working, the reason may be that the air pressure is not enough, the trigger mechanism is blocked, there is also a worn ball valve, here we just need to adjust the air pressure, add a few drops of lubricant from the side of the trigger and try to press the trigger several times, if it is still not effective dismantle the trigger to clean it and replace the ball valve in time.

If the rivet nut cannot be withdrawn after riveting, check the motor reversing switch, adjust and replace the seal and add grease.

If the rivet gun screw cannot be reversed, the motor seal may be worn and leaking, the air supply tube is blocked, the pneumatic motor is blocked, adjust the stroke, replace the seal, add lubricant and make it more lubricated, the motor is blocked then the motor needs to be dismantled for cleaning and lubrication of the machine.
