Ebubekir, These drill hammers run on air pressure. The PSI should be set 18-24 lbs. Also the CFM should be 110 -120. I hope this is helpful information.
It's possible that you don't have enough air pressure. It takes 92.5 CFM at 110PSI per drill. You would need 185 CFM at 110PSI to run both drills at the same time.
We have 2 trucks setup. 1 works great and the other won't run both drills at the same time. We actually used the compressor on the other truck and it was the same. It's something with the drill for sure. Any other ideas? And thank you for the quick response. Also this video is great!
