WARNING: Do not operate this unit until you read and understand this instruction manual for safety, operation and maintenance instructions. Never tank pressure. EnglishGrounding Instructions. WARNING: Risk of Electrical Shock. In the event of a short circuit, grounding reduces the risk of shock by providing an escape wire for the electric current. This air compressor must be properly grounded. The tank will fill to cut-out pressure and the motor will stop. 7. Compressed air will be available until it is used or bled off.Before starting compressor, pull the ring on the safety valve to make sure that the safety valve operates freely. Always use identical replacement parts. Full One Year Warranty. Cut-Out Pressure: When an air compressor is turned on and begins to run, air pressure in the air tank begins to build. Troubleshooting Codes. Check the accessory air requirement. If it is higher than the CFM or pressure supplied by your air compressor, a larger compressor is needed to operate accessory.

SAFETY VALVE If the pressure switch does not shut off the air compressor at its cut-out pressure setting, the safety valve (G) will protect against high pressure by popping out at its factory set pressure (slightly higher than the pressure switch cut-out setting). DRAIN VALVE The drain valve (H) is located at the base of the air tank and is used to drain condensation at the end of each use. See Draining Air Tank under Maintenance.When the air compressor reaches cut-out pressure, the check valve closes, allowing air pressure to remain inside the air tank. TANK PRESSURE GAUGE The tank pressure gauge (B) indicates the reserve air pressure in the tank.It is normal for this fan to blow air through the vent holes in large amounts.http://dacselectrosystems.com/images/deskjet-6122-service-manual.xml

The cooling system is working when air is expelled. AIR COMPRESSOR PUMP The pump compresses air into the air tank. Working air is not available until the compressor has raised the air tank pressure above that required at the air outlet. MOTOR OVERLOAD PROTECTOR The motor has an automatic reset thermal overload protector. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before restarting. The compressor will automatically restart after the motor cools. OUTLET PRESSURE GAUGE The outlet pressure gauge (C) indicates the air pressure available at the outlet side of the regulator. This pressure is controlled by the regulator and is always less than or equal to the tank pressure. REGULATOR The regulator (D) controls the air pressure shown on the outlet pressure gauge. Turn regulator knob clockwise to increase pressure and counterclockwise to decrease pressure. UNIVERSAL QUICK CONNECT BODIES The universal Quick Connect body (E) accepts the three most popular styles of Quick Connect plugs: Industrial, automotive, and ARO. The two quick connect bodies allow the use of two tools at the same time.INSTALLING HOSES WARNING: Risk of unsafe operation.

It will get up to about 170 psi, lift the safety and keep on running. I thought it was the pressure switch but I have had other opinions given to me. One being NO175925V valve plate. Why could it be this and how do you check this part to prove it faulty. The other being NO36518 connecting rod assembly, how do I troubleshoot this part. Lastly the pressure switch how can I test this and eliminate it. Any ideals or if you have had a lot of experience with these parts please let me go with it. I know most times there will be one part that causes 90% of all the problems. Anybody have any experience with that. Compressor comes on, runs good, lifts the safety at around 170psi continues to run. I think the tank is pressuring up because of the amount of time it takes the tank to de pressure after the safety lifts. The pressure release valve will blow at between 165-170 psi if I remember right. If your blowing the safety valve off a 170 psi then its a sign that the Pressure Switch Part Number: N003306SV is defective or clogged.Before you replace it try this first.I was told that this is the correct switch for it, but it just can't get past 120.is there another switch rated at 120 p.s.i.that I can use?. thank you in advance for any help you may be able to give me.These three things will give you a good place to start in troubleshooting the compressor.Hope that helps.Good luck. Tinker Took the gage off but there doesn't appear to come apart. Is my diagnosis incorrect? The manufacture does not supplit replace parts for the air gauges. You will have to replace it with a new one. -WJA I would look more into either the N017592SV Valve Plate. Check for worn or damaged parts. Or it could be the N036518 Connecting rod assembly with the cylinder and rings. It could be worn to the point where air is blowing by and not getting into the tank. Hope this helps, -WJA I've replaced the air check valve and when I shut it off I no longer hear air escaping, but it still won't exceed 50psi.

The knob doesn't seem to work right and when I remove the knob I find a spring inside that sets on a piece of plastic. I'm assumming the spring pushes down on the plastic as the knob is tightened allowing the pressure to be controlled. Do I need to replace the whole manifold or is there another fix for this? If so remove it and carefully pull out the spool steam and nut.The spool steam should sit in a tube on the bottom of the nut with a small spring in between them. Gently pull the steam from the tube on the bottom of the nut and and you should see a o-ring.This steam with the help of the spring moves back and forth in the tube and regulates how many air psi is allowed to the working side of the regulator.If its frozen then it will not respond to the control knob.If it is frozen then clean it well and apply a little grease to the o-ring and spool reassemble it and place a little grease on the disc you took out with the big spring under it that should get you going.I don't know what compressor you have so i'm not sure of what regulator you have.Some regulators have no nut on the back so the spool comes out the front of the valve body.Hope this helps.Good luck. Tinker Is there a diagram that shows the assembly. I have no nut on the bottom but the knob itself unscrews. There's a large spring and a disc that has an O ring. Under that there's a smaller disc with a spring at the bottom. I'm not sure I'm reasembling it correctly. Does the disc with the O ring go in first and then the big spring or does the big spring go in first and the dis with the O ring sets on top of the spring? It runs but will not build more than 35-40 lbs of pressure. It continually runs. What do I need to fix this problem? If the regulator knob is defective could that cause the problem. If so do I need to replace the manifold unit or is there another solution? If you take the pump apart I bet you'll find a damaged piston ring and cylinder or a broken reed valve.

The problem is you would have to replace the whole pump assembly.Hope this helps.Good luck. Tinker The aluminum tube that comes off the pump is so slick, the rubber hose slides off it no matter how much clamping pressure I put on it. I just have to remove the pump unit and slide the hose back onto the tube and clamp it back on and I'm good for a few months. The next time it happens I think I might try some super glue, lol. Take care Michael I seen other had this problem and the diagnosis was pressure switch. I ordered and changed the pressure.And it looks like others do to. I don't know how to fix this either. What was wrong with it.If so your safety valve is bad. If its being activated over 160 your pressure switch is bad.They made two pressure switches for the type 1 and the type 2,3,4,5.Your showing the type 1 which should be the N003307SV.Not the N003306SV. Also that series of compressor had a problem if the tank was not drained after every link removed and slag would work down the pressure switch tube clogging it and not allow pressure to get to the switch thus allowing it to build up enough pressure to kick the safety valve on.Most of the time the switch air inlet would be filled with mud and dirt.

These are the “humps” on the back of the motor. Use a capacitor tester or if not available, test continuity across the leads of the capacitor. Try the following: This should be held on with 4 long bolts and nuts that run the length of the motor. Use a screwdriver and small hammer to gently remove the end cover. You should also see a round brown disc. Extending from the round disc you should see a long slender piece of copper or other material, the size of a wooden coffee stirring stick. At the end of this stick are electrical contact points.

These points should be “closed”. Sometimes corrosion will build up on them. Take an emery file and file between the contact points to clean them. When the motor builds up speed, the small weights on the springs swing out and separate the points. This opens the circuit between the starter capacitor and the motor. One of the round hump capacitors helps to start the motor and when the motor reaches high enough speed the weights and springs open the points and the starter capacitor then stops sending a charge to the motor. At this point, the other capacitor, the run capacitor continues to keep the motor running. If there is corrosion on the points, the starter capacitor never kicks in and helps the motor to start. Do not over tighten belt, it will break the crankshaft or burn up a bearing. Compressors do NOT squeal when the belts slip. It sounds like the motor is slowing down but what is really happening is the belt is slipping. If you have a 230 V motor converted to 120, you may have lost some pulling power. If it is the wrong motor not matching the correct motor pulley you may be overloading the motor. You may have an under-powered motor, or the motor is too small. Look at the amp rating on the motor plate and put an amp probe on the motor if and when it starts bogging down. You could also have under size wire from panel or too long of a run on wire itself from panel. If you don't have an amp probe it's recommended to take the motor in to a local repair shop or have an electrician come to your house for further diagnosis. Is oil-free or oil-bath best. Will I need a two-stage unit or is a single-stage unit sufficient. How much CFM will I require. How much PSI will I need? Not to say this is unimportant for the homeowner or hobbyist, but there is a compressor for every demand and job out there; the more you know going into it, the easier it'll be when you're at the outlet about to make your purchase!

Most oil-free units on the market, however, do not put out high CFM, generally 6 CFM or less. Also, these units are generally louder than oil-bath units, so if noise is a factor, go with either a “silent” oil-free compressor (the “JC10” Rolair unit or any of the California Air Tools units, for instance) or an oil-bath compressor. Oil-bath units are always recommended for longevity, and they simply put out a heck of a lot more CFM than any oil-free unit will be able to manage producing. Most contractors and all industrial applications and commercial garages demand a heavy-duty oil-bath air compressor as it will put out the CFM you need and will simply last a lot longer than any oil-free unit will. However, if you're a small contractor that has one or two workers, an oil-free unit may be sufficient. If you're simply using a trim gun to install trim in a kitchen, this doesn't demand high CFM so you can probably get away with using a smaller oil-free unit. Your application, whether it be a roofing nail gun, sand blaster or die grinder, will have a CFM requirement specification (you can find this in the manual for your tool). You need to choose an air compressor that at least meets that minimum CFM output. If an air compressor doesn't have the required CFM for your tool, it was run constantly and you risk burning the motor, pump or both, and your application will suffer for it as well. Be sure the air compressor puts out the required CFM (and ideally a couple more CFM) for your application. The CFM spec is related to duty cycle of a unit so we'll discuss that this term means now. Below is a very handy chart and info on what duty cycle means for an air compressor (and to give credit where credit is due, this very helpful information comes from VIAIR at ): Heat dissipation rates may vary depending on ambient temperatures and operating conditions. PSI isn't as important as CFM because most applications don't require high CFM.

Any typical air compressor puts out at least 120 PSI, which is sufficient to run any nail gun, grinder or blow gun.It doesn't have anything to do with the number of cylinders or heads the pump has. Also, a two-stage unit will recycle quicker (pump up quicker) and has a higher CFM rating than a single-stage unit. For most homeowners and hobbyists that are using small nail guns, blow guns or pumping up beach balls, a single-stage unit is definitely sufficient. Even most small contractors can get away with using single-stage units if they have a small crew. And, sometimes buying cheap is worth it if you don't use the air compressor often, so what if the valves crack or piston ring(s) wear out. You can probably buy a replacement for the same amount as a repair would cost.I get it. However, it most cases it is certainly worth it to increase your budget and buy a unit manufactured by a reputable brand you trust; I'm thinking Campbell Hausfeld, Rolair, Jenny, Champion, Ingersol Rand and Coleman Powermate. Not only will these units typically be of a higher quality, but it's worth it just for the fact that most (but not all) units made by these manufacturers have replacement parts available, and offer great warranties. They also usually have a large network of authorized service centers available nationwide, so when you need to have the unit repaired, it's convenient to do so. It's the old adage, spend more now so you won't have to down the road. The more you know going into the purchase the better, and knowing what you need will save you money now and later. The specs and stickers on the unit are not always accurate, and add confusion instead of critical information to buying decisions. Then you can figure the true CFM from the difference in starting and final pressures, times the volume of the tank, divided by the time it took to pump up. You can also time the pump-up cycle from the cut-in to the cut-out pressure, since that's how one usually runs a compressor.

These true performance measurements are impossible to fake. This should be clearly marked on the tank itself by the manufacturer. Record the amount of time that it takes to refill the tank while paying close attention to the compressor's tank gauge. You will need to record the psig (pounds per square inch) at two separate times in the refill process: once at the moment the compressor kicks in and once at the moment the compressor kicks out. For example, if the compressor kicks in at 75 psig and kicks out at 100 psig then the difference would be 25 psig. This is the number of cubic feet that your compressor pumps in the time it took for your tank to fill (recorded in Step 4). To do this, take the number of cubic feet found in Step 7 and divide it by the number of seconds it took to pump this amount. Multiply the result by 60 and you have the CFM of your air compressor.
