Troubleshooting low pressure in pneumatic tools underground

[Alan]

If your rock drill is struggling, you might be questioning whether the issue is with the tool itself, a hose leak, compressor malfunctions, or moisture buildup affecting the pressure in the line. What’s your organized approach to tracking down pressure loss underground without spending half your shift chasing after ghosts in the compressed air system?
