Compair Hollman compressor wont build pressure
We recently purchased a drill rig with a Compair Hollman 600/250 compressor. It only operates on 100psi when hammering and drops to about 30psi when the drill bit is lifted. It will build up to 250psi when the air flow is cut off.
I emailed the Garner Denver agent but they have no manuals to assist.
Can you advise if this is the best we will get out of the machine?
