    how do i know if its the pressure gauge or the regulator that is bad ? the gauge wont register any pressure readings at all when i am using the compressor, but my nail gun works fine , if anything it shoots a little to hard.

    Moreover, if your compressor has an Air Intake Filter, it
    should be cleaned on a weekly basis (assuming you are using
    the compressor about 3 days a week). When the filter starts
    to develop debris that is becoming harder to clean out, or
    you notice any tears or holes in the filter, the filter
    should be replaced.

    In a rotary screw compressor, oil should be
    changed about every 7000-8000 hours. This depends on the
    type of compressor you purchase. For a Reciprocating air
    compressor, generally you would change the oil approximately
    every 3 months. For a more accurate time frame, I'd need your model number to find the recommended schedule for your
    compressor.

    So, you're using an oil based horizontal tank unit ; Belt Driven? Horse Power? Max PSI? If you have the model I can pull up the spec sheet.

If the regulator is inline you need de-energize the compressor to remove the regulator.

Regulator Problem. Both Gauges stay at same pressure when trying to adjust the outlet pressure for tool settings


It sounds like a contaminated regulator, possibly due to moisture if you have never drained the tank. If it is a cheap air compressor then the best course of action would be to install another regulator as it is not worth the time to try to rebuild the regulator as most likely it is not a quality part. I would look into Wilkerson or Speedair brand parts to fix your issue.

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.

My compressor will not go over 20 psi i have a craftsman 921 4 gal 125 psi compressor and it will not build past 20 psi i do not know how to get to the pistons and stuff what do i do?


The problem with compressors not building pressure is usually a bad pressure switch or bad regulator. Does the motor shut off at 20psi or does it continue running and not build pressure? If the motor continues to run with no increase in pressure, the you should go over the machine looking for air leaks from your regulator back all the way to the motor. Any air leak while the compressor is running can cause the pressure to "peak" way before the intended shutoff that it is regulated to.

The compresor is not building up the pressure, it only reaches like 15 PSI .. and is not the drain valve


check the regulator valve. the black cap must be pulled out slightly to allow it to turn. adjust that while watching gauge for change. there is also another pressure release near the pump be sure it is seated fully.

I have a Sears evolv 3 gal air compressor that will not inflate a auto tire, even a partially de-flated tire. I let the pressure build to 100 psi and checked all fittings. Still wil not do it. Compressor...


The evolv air compressor was primarily designed to power a very small nailer. The pressure regulator (knob in front) should be turned clockwise till it stops to attain full pressure. At this setting it should air your tire. If not you may have a defective regulator. There is a trick to get full pressure from your tank. Notice the small pressure safety valve on the side of the unit. You could remove this valve and install a fitting giving you two ports. One for the safety and other for a quick disconnect. This second port will give you access to tank pressure without going thru the pressure regulator. This mod is safe because you still have access to regulated pressure when you need it. Good luck

Does it run? Does it stop running? Does the pressure gauge read anything at all? Is there a regulator on it? Can you take the reg off? A bunch of things to check, get it running and let me know what you find, and I will try to tell you what's next.

Compressor won't build psi above 30,is this typical of the regulator or pump? the compressor is a 3 gal craftman about 1 yr old.


sounds like the regulator is faulty, normal running air should reach 110 psi, this will allow you to run tools...

Will only produec 20lb of pressure


I have the same make/model. Connect a device to your air line (impact, blow gun, doesn't matter anything that will use air). Operate the device and note if the pressure on your output gauge falls, and then rises back to 20# when you let off of the device. If it does, this indicates that your regulator is either defective, or it is adjusted too low. Try adjusting the regulator knob, operating it in both directions, and note the pressure on the output gauge. If you can get it to rise, you're home free!
