On electric motors with two capacitors, one is a start capacitor, the other is a run capacitor. Start capicitors have plastic cases and are rated from 200mf to 400mf and higher depending on the size of the motor. Run capacitors are in the 20mf to 40mf range and usually have metal cases. If you have an electric motor service center in the area they can recommend what size you should use for the size (HP) motor you have.

You didn't state your model number but the only place I could find that has manuals for Clark air compressors is Clark Power Porducts UK at: www.clarkeservice.co.uk/product_manuals/air_compressors.shtml. Usually if you have an air leak at the pressure switch when the tank is full and after the motor shuts off it is indicative of a stuck or broken tank check valve. Sometimes they can be cleaned and will work for a while but more often than not they have to be replaced.

It is part and parcel with the type of compressor you have. I expect it is similar to the pump on a Wagner paint gun rather than a rotational compressor with pistons more common to larger capacity compressors. It vibrates, it is supposed to. If that is problematic, buy a compressor with at least two cylinders.

Knowing the point of leak will confirm if the nipples, pneumatic hoses or joints are the culprit. Apply more pressure and listen to the leak , feel the leak using your palm which will confirm, if so remove the hoses and cut and re-tighten them. also if the leak if from the pressure cut off switch, pressure meter or safety valve, it must be removed and repluged or replaced.

There is a differential between the shut-off and start pressures of about 20 psi and these pressures are adjustable on some switches. What the switch must do as well is relieve the pressure on the compressor head so that the motor does not try start against a load. You shoud hear the pressure relieving when the compressor shuts off, if not you need to rectify this problem, otherwise check the pressure that the motor cuts in at and set it or replace the switch.

ingersol-rand corp. makes these compressors for clarke

take it back to the store where purchased with the sales slip and exchange it,if not possible,then clarke is made by ingersol-rand corp. call them

Hi

Can you hear any leakage, if not then I would suspect a valve is jammed open.

Gently tap valve housing with a soft hammer, may dislodge the valve.
