Cosmo compressor runs but not charges


i was given a 6 litre cosmo air compressor by a friend.


my problem is that there is no instructions with it, so i have no idea what switches,valves, etc should be in what position etc.

The compressor starts and runs smoothly but does not seem to charge, any help would be great

Cosmo compressor won't build pressure
by: Bill

While there are many types, brands and models of air compressors on the market, when we are talking about the small, home or workshop type air compressors, they have many things in common, including, after a time, running but not building pressure.

Rather than answer that same question for every make, model and brand, I've added a troubleshooting page about why air compressors run but don't build pressure.

Have a look at that page, apply the information to your Cosmo compressor, and add a comment here about what you found when you applied the checks.
