Prior to starting the unit. Look at the pressure gauge. 1. Make sure the regulator is set to the desired PSI. 2. Make sure the unit is connected to an AC circuit that is required to support this machine. If you have high end AC outlets that are intended for a low power i.e. 10 AMP and you connect this unit to the circuit it may disconnect. So try an outlet on the outside of the house intended for higher amperage machines like those used outdoors.

The problem may be with the power source. Check that first.

Now for the unit itself. 1. Connect the unit and set the pressure regulator to max pressure. 2. Turn the unit to Auto/On the unit should only run until the pressure is reached. 3. Connect a pneumatic tool to the unit and drain off pressure. Once the pressure gauge drops below the set value the unit should start again. If not then you need to take the unit to a certified service center to have the regulator checked.

On my air scout the regulator cap, which is threaded to receive the bolt attached to the regulator knob was stripped. It's cheapo metal. I removed that and the knob (which is held onto the bolt with a smaller reverse-threaded screw, and replaced the cap using a larger diameter bolt I place of the knob. Works.

Broken reed valves- assuming the regulator is adjusted to maximum air pressure.

These are located on the face of the pistons and require partial disassembly of the compressor head to serivce.

When installing the new ones, add a drop of light duty thread locking compound to the threads to insure the screws do not fall out in use.

if it's leaking from the center ,try loosening it let air blow out & tigthen .--- if it's leaking from the theads try tigthening it some more without breakage //////// this valve is the same as a metal radiator petcock with pipe threads that are tappered // return the compressor if still under warranty or try pipe dope -- check for crossed threads--buy new petcock from auto parts store .....a street elbow & 4'' of pipe & quarter turn vavle from the home depot ( or similer supply store ) works nicley as a replacement / this way you can reach the valve to drain the water with out laying on the ground.--------------1/4 pipe thread i think .

67 head 65 gasket 64 reed valve plate 63 ring,this one goes under the reed valve plate 62 screw that goes thru the 61 piston 60is a ring that sets on the top of the connecting rod screw the piston with the ring into the top of the connecting rod then take the connecting rod end cap off and cover the studs with some rubber tubing.This will protect the crankshaft when you push connecting rod and piston assembly in to the sleeve that is seated in the block.The ring should be flexible enough to push into the sleeve,if not a bit of oil should help.Guide the connecting rod on to the the crank shaft.I hope this helps and thank you for using FixYa.com

you can go to, sear web page for parts brake down and part number. when you log in, look at the top right for parts, than type in your model number. check your tank valve, if it don't close, air well leak back.

This problem is not uncommon with small compressors and the inexpensive plastic regulators they use nowadays. The one surefire way to stop it is ti install in in-line valve before the regulator outlet, even if it involves the double ended & threaded brass soupler so they both fit on. This way you can just turn the handles across the line effectively shutting off air flow. I have two pancake compressors and ended up doing the very thing.

Then when time comes to hook up a hose and tool, just switch the handle back and you have air.
