Just picked up a 2hp, belt driven Sherry air compressor (150L, I think). Didn't come with a manual and looks about 30 years old - anyone know where I could get a manual from?
Cost me =A350, which I think is a bit of a bargain as it looks very well made, aside from some cosmetic rust
Not many - but not sure what oil level it should be filled to and why the pressure switch seems to leak air until you turn the motor off... also need to get a regulator thing but they're not expensive from MachineMart or similar...
Isn't there a glass? Normaly oil has to be filled up to the middle of it. If there is none, oil often has to be filled up to the inlet hole for the oil.
Don't know this specific pressure sensitive switch. But they all have a release valve that removes the pressure in the tube between compressor and reed valve of the tank. This is for making the starting easier. Normaly they open when the motor is stopped. So it might be a different construction or defunct.
Im not qualified in this, but from the pics I would be wary. a firm tap with a toffee hammer should 'ring', but that is only an indication that it isnt totally shot. given it holds pressure it isnt likely to be totally shot. Is there a diving shop near you? they have to test cylinders on a regular basis,so should be able to offer better advice, or test it. a bolier tester from your local club might also be able to help, after all its only about traction engine sized... There is a lot or energy stored in a compressed air tank, be careful, if in doubt... dont.
