Compressor groans??

I've got a Husky 60 gal compressor and today while I was using it painting some parts for my truck it started to groan when ever I was flowing air. I checked the valves and they were open all the way, stopped and drained the tank of water, very little found. Don't know why it did that, anyone with an idea??

Thanks

You should check the oil level in it, it might get a little low, or maybe there is no oil at all... It happened to me last year, I was using the compressor and one day it stopped and I needed to change the motor on it... My father never put oil in it and he had it since at least 20 years . Another problem I can think of is there might be a loose screw that is making everything shake or the strap on it is not aligned correctly. Good luck with it.

I am considering purchasing a husky 60 gallon compressor. what do you think of the quality? I will use it for running cut-off wheels and the small angle grinders. would it run those sufficiently? I haven't seen any actual cfm ratings for it just the cfm ratings husky puts on the tank.

any info. would be much appreciated, thanks.

I second that. I do like that it has a cast iron pump.
