150 PSI pancake has never pumped to 150 PSI. IT always stops at 135 PSI.
If it's pumping up to 135 psi, shutting off and then restarts at the same pressure point since it was new, the pressure switch may have been set low at the factory. I don't know which model you have but most pressure switches have directions inside their cover as to how to adjust the cut-out and cut-in pressures. Be careful doing this, overpressuring the tank is dangerous. There is an adjustment screw or bolt that changes the pressure on the switch spring. Some pressure switches have two screws, one for cut-in and one for cut-out pressure. A few have one that adjust both pressures. If you do adjust the cut-in/cut-out levels, do it slowly and cycle the motor a couple times between each adjustment to see where it turns off and on. If the compressor is doing what you want it to, only pumping to 135 psi, it will live longer than if you adjust it up to 150 psi. Those last 15 psi of air are hard to get and will mean the motor will be running longer and more heat will be building up in the head.

An air compressor such as the one that you borrowed is very useful for airing-up tires, connecting a nailer for wood working projects and spray painting with a cup gun. All that you need do is plug it in to a 110v outlet and it will fill with air to capacity. To access the air you will need to plug an air hose into a quick coupler and adjust the air pressure with the knob showing two direction arrow. Unless your friend has included an air assisted water blasting wand that would also connect to a water supply, I do not think that it would be useful for cleaning. I have used a compressor such as this with an air nozzle or air blasting the air conditioner condenser fins and the drain to the evaporator inside the house. It will also be really great for cleaning the mower or any outdoor tool that accumulates oily dust (air filters). With a small sand blasting attachment you could remove old paint from the patio furniture or any wood or metal surface needing a good blasting to make it look like new. Sand blasting would not be practical for house/ deck/ fence because it would take too long and use too much sand; then there would be the sand cleanup. Have fun with the compressor and clean-up projects.

pull the line and make sure your regulator is not plunged or the regulator is not rusted up and plugging
Testimonial: "HAVE DONE THAT AND IT SEEM TO BE THE LINE REGULATER . THANK"

The compressor has a max psi setting of 150.If the pressure is not reaching this or is only stabilizing at a low pressure you have an air leak around a gasket somewhere.If it is reaching 150psi and not shutting off your pressure switch is bad.Replace it.Check your owner's manual for a part number or go to www.factoryauthorizedoutlet.com to find the part.

This unit was purchased just as the new 150PSI units were starting to be delivered. so your explanation sounds correct (mis set at the factory) This is what I assuned to be the case, but I did not know where to find how to set it. Thanks for the reponse. Fo rnow I wll leave it at the 135 for now and adjust it if needed.
