If this is a no oil unit, more likely your piston and sleeve are damaged and need to be replaced. thy are not that hard to do. when you get your new parts you'll see what I mean. good luck

SOURCE: unit builds to 25-30 psi then shuts off. You must

unhook the output line from the pump. run unit for 5 to 10 min. if no problem, check the tank valve at the end of you out put line, it screws into your tank. that valve must shut off at every down stroke of the piston, or air well flow back to the pump. will put an overload on the motor. good luck

SOURCE: Will not build up air perssure over 50 psi. and

The motor will run until the pressure switch detects approximately 150psi in the tank. If it never gets to 150psi, it will continue to run. If you are not getting over 50psi in the tank check:
1. that the drain valve on bottom of the tank is fully closed. Don't use a wrench on it but it must be tightly closed by hand.
2. that you don't have any air leaks on the top end of the compressor or on your lines going out of the tank.
If these are OK, your problem lies either in a damaged valve plate or cylinder/piston. You can remove the head and check the condition of both the cylinders and the valve plate. All reeds on the valve plate have to be in good condition with no bends, cracks or warpage from over heating or debris from using the compressor with no air filter. The cylinders should be smooth with no scaring. If a cylinder is damaged you will have to also replace the rings or piston assembly. None of the air compressor companies make an oversized ring set so you can lightly hone cylinders but you cannot have them bored out oversized to correct any damage to the cylinder walls.

SOURCE: How do I get the pressure build to 90 PSI It stops

There should be a pressure regulator with a gauge hooked to it. They usually have a knob that you turn to the right to increase the output pressure. If the compressor itself is not building more then 50 PSI then there is a problem with the unit.

Makita MAC5200.Brand new.Just broke-in. Pressure goes to 140 PSI and stops.Tries restart at 110 PSI.Motor"Humms"only.Will not restart until pressure below 20PSI.

There is a part called an unloader. It reduces the pressure on the compressor when the unit stops at the desired pressure. The actual unloader may be part of number 50 in this diagram.

Hello I have a 20 gallon kobalt model 033204. I just replase pressure switch but does same thing. When I tur on the compressor jus build 50 psi and shuts off.


This usually occurs when the motors internal thermal / amp breaker opens due to overload or weak breaker. Use an amp gauge to test for too much amp draw. If amp draw is normal, then problem could be the in-tank check valve leaking pressure back to the pump overloading the system, or weak capacitor or weak breaker. Bypass the breaker temporarily if the amp draw is normal to test system. Good luck

I have a model FP209501 Air Compressor 2 Gallon,


2 gallons is small to begin with u need to buy an in line pressure adjuster/regulator their a few bucks and can be attached to the paint gun or line and will keep the pressure at ur adjustment the regulator on the tank sets the tank pressure at 50 so when u us it will let it drop down to about 45 than start up to build the pressure up to 50 than shuts off than repeats it self the inline keeps pressure steady even if tanks are at 200 psi

My PRO-SOURCE air compressor will not go over 50 psi


Your compressor has got a 'ring' problem. The rings on the pistons that compress air are leaking air by them and need to be replaced. Unless it's the 'pressure release' leaking. When it gets to 40 PSI or so, unplug it and listen for a leak. If no leak then it's the rings. inside on the piston. If you adjust the pressure switch all the way low, it might shut off near where it builds pressure to and you could at least use it some.

I have worked on many makita compressors and have run-across this problem on a few of them. Your compressor has a check valve that is supposed to hold tank pressure after the switch reaches set pressure. There is an unloader valve built into the pressure switch that releases the pressure in the discharge hose after the unit shuts off. The unloader allows the compressor to restart with-out any pressure in the discharge line. If the brass check valve is leaking pressure back into the system, air will leak out of the unloader valve. Follow the discharge line to the tank and you will see the brass check valve. To test valve for fault, run the compressor till it builds around 80 psi and unplug the unit from the wall outlet. Remove the 1/4" hose connector from the check valve and check for air leaking out of the valve. If it is leaking you can order form www.toolpartsdirect.com. or call the makita 1-800 number. The price is about the same. Good Luck on your repair.

The compressor only reach 50 PSI.


Does the compressor continue to run but not build more pressure? In which case it is an air leak most likely, or does the compressor shut off at 50 PSI? In which case it is mose likely the pressure switch. If it is an air leak you can un-screw the guage and coat with putty or teflon tape and reinstall to clog the leak around the threads..
