Chicago Pneumatic 1/4" Air Screwdriver - Answered Questions & Fixed issues

Look for something called an unloader valve. This valve is usually connected to the pressure valve that opens when the desired pressure is released.

Hi, my name is John. Welcome to FixYa. Low oil level, and poor air circulation. Thanks for choosing FixYa....John

The sullair 185 has a low oil pressure override button that you have to hold in while starting. after the oil pressure builds up(takes about ten seconds) you can release the button and the machine should continue to run.

On most compressors of decent size (yours fits this category), the shutoff and startup pressure points are adjustable. This is usually done using a pair of screws under a pretty accessible cover. The on/off switch usually goes through this cover and the smallest of the air lines will go here, too.

Run the compressor with this cover off and watch which set of contacts opens when it shuts itself off. The screw that adjusts how resistant these contacts are to opening is the one that determines at what pressure the unit will shut off.

Turn the screw 1/4 turn clockwise, bleed down the compressor enough for it to start back up, and note its pressure when it shuts off. This will help you determine that clockwise is the right direction, and roughly how much more to turn it to hit your target pressure.

One other thing to keep in mind. Many compressors have an adjustable outlet with a gauge. If you've got two gauges, it's likely one is for the outlet and the other for the tank. If you've got two gauges, make sure you're reading the right one. If you've got an outlet gauge you also have some kind of easy to use control for adjusting it without taking any covers off.

If this doesn't help, some clarification would help, specifically the make and model of compressor.

On the teflon tape, I see it applied the wrong direction frequently. Not saying this is the cause of your problem, but seems a handy place to mention it.

When looking at the business end of whatever male fitting is getting the tape (business end being the part that meets the fitting first), wind the tape CLOCKWISE. This way, when you install the fitting, the friction from the threads is trying to tighten rather than unravel your tape.

your not return balve is stuck open or your valves are sticking the pressure from the tank is going back to the pump so when the compressor goes on the compress stroke its very hard as it has to open the valve with pressure behind it its hard to explaing buddy but on the tank you wil see anon return valve from the pump unscrew it and inside is a rubber with a spring turn the rubber around and try this if doesnt work you need to inspect the valves (if sticking) good luck

The estop button is not the proper way to turn the unit off use the start/stop button .You must first open the estop button then press the start button

Your referring to central pneumatic. It is a Chicago pneumatic. Correct your wrong g answer. Don't miss lead people

An O-ring has probably failed. Harbor Freight Tools does not generally offer parts for their tools, but in most cities you can find someone who repairs air tools. Check the Yellow Pages or Google it.

Take some contact cleaner and spray it in the air intake couplin and then plug it into you air line and pull the trigger.be careful not to get sprayed in the face.do this a couple of times them do the same thing with tool oil . if it is dirty most of the time this will solve the trouble.

the check valve is normally on the end of the air line from the compressor into the tank most are screwed into the tank with the compressor line attached to it.

try a large pair of pliers. straighten the staples as much as you can, grip one leg with the pliers about 1/8" from the wood, and tap the pliers with a mallet or wood block. alternate "till you can grip the crown.
