Porter cable regulator manifold is completely stuck. What gives?
This happens due to lack of lubrication. The air that runs thru the regulator is very moist and caused the internal parts of the regulator to rust. With no air pressure in the tank, take the regulator apart and lube the threads on the adjustment knob. Also remove the plug on the rear of the regulator and lube the plunger valve. You may find that the valve is stuck to the plug. Separate the valve from the nut and clean / lube. You may also find that the regulator is too far gone and needs to be replaced. Good luck with the repair.
I have a porter cable bn200sb braid nailer. It is cycling but not firing nails
This happens when the driver is not returning to top of the cylinder. Remove the driver and make sure that it is not slightly bent or not lubed enough and sticking to the cylinder. Also check the driver piston seal ring is not too loose. The driver should move easily within the cylinder but not so loose that it just drops to the bottom of the cylinder. Good luck with your repair.
New trigger valve leaked air and gun won’t fire. I have replaced the trigger valve twice and the problem is the same on both new valves. Porter cable FR350a.
I find that the trigger valves in these guns are reliable and that most problems with random fire is lack of lubrication and adjustment of the safety foot. Assuming that air does not leak when you connect air supply and leaks from trigger when attempting to fire. This indicates a lack of lubrication of the head valve. Remove the head valve and lube with white grease.
Test the gun, of ok then you are done. If no joy, then check safety foot for adjustment. How to test if the safety foot is the problem.
Remove the nails, remove the trigger leaving exposed the trigger firing pin. Adjust air supply to 100 psi and connect to gun.
Assuming no leaks quickly depress the trigger valve pin all the way in. If the gun fires then the problem is with the safety foot and or the actual trigger is not pushing the firing pin all the way in when attempting to fire. Make adjustments accordingly. Good luck with your repair.
Wrench question
An air-powered impact wrench runs off of an air compressor with a tank – the air compressor should have at least a 10 gallon tank and be able to generate at least 3hp. Also, an impact wrench requires special sockets that are designed to withstand the high torque applied by the wrench.
Porter cable compressor will not come on soon enough
There should be a pressure switch that can be adjusted. You should be able to adjust high pressure shut off and at what pressure you want it to restart. If you give me a model number I can help further.

How do i take apart a model 7812 porter cable vacuum to change brushes
The brushes are not replaceable - it is an entire motor assembly.
1) remove the 2 screws holding the top handle on
2) remove the 2 screws on the top of the housing (front either side of switch)
3) remove single screw holding cord hook (rear side of housing)
4) remove small torx screw in the shaker handle and remove the handle
Flip over and using a screwdriver begin to pry the top cover off the housing (easiest to get the front side off first)
