I own a 5 HP Coleman compressor. It is rated at 7.3 cfm at 90#’s of pressure. Recently I purchased one of your orbital sanders. When I went to use it yestereday, it would spin freely, but would almost immediately stall, when I touched the disk to the surface [it this case fiberglass].
What do you think is the problem? Is my compressor too small?
Thanks.
