It needs to mounted at the lowest part of the tank where the water accumulates. There should be a drain petcock in the bottom of your tank, remove it and install the auto drain in its place.

How do I take apart a dewalt d5141 compr3ssor?


This number is for the D20114 its the safety valve that can not be set to a max basic pressure .
its strange but its not adjustable it can be defect i have one time the same the experience there is not a adjustable Pressure Switch on this model , the moast compressors have a 8 to12 bar adjustable.pressure switch.
Very important This safety valve gives an electronic brake between the pump and to a end of top about 10 bar . if its not switching off then a drain valve opened . and blows all the air out. (but only over 10 bar ) the max pressure on the tank , the moast tools are working on a pressure from 6 to 8 bar.
-----------------------------------------

Checking Safety Valve
WARNING: Risk of bursting. If the safety valve does not work
properly, over-pressurization may occur, causing air tank rupture or
an explosion.
Before starting compressor, pull the ring on the safety valve to
make sure that the safety valve operates freely. If the valve is
stuck or does not operate smoothly, it must be replaced with the
same type of valve.
Draining Air Tank (Fig. 1)
WARNING: Risk of unsafe operation. Risk from noise. Air tanks
contain high pressure air. Keep face and other body parts away from
outlet of drain. Use safety glasses when draining as debris can be
kicked up into face. Use ANSI S12.6 (S3.19) ear protection as air flow
noise is loud when draining.
NOTE: All compressed air systems generate condensate that
accumulates in any drain point (e.g., tanks, filter, aftercoolers,
dryers). This condensate contains lubricating oil and/or substances
which may be regulated and must be disposed of in accordance with
local, state, and federal laws and regulations.
1. Ensure On/Off switch (A) is in the OFF position.
2. Move compressor into an inclined position so drain valve (H) is
at the lowest point (this will assist in removing moisture, dirt, etc.
from air tanks)
3. Place a suitable container under the drain valve to catch
discharge.
4. Grasp black lever on drain valve.
5. Slowly rotate lever to gradually bleed air from air tank.
6. When air tank pressure gauge reads 10 PSI (275.1 kPa), rotate
valve to the fully open position.
7. Close drain valve when finished

Air compressor tank will not fill?


STOP. What pressure does the gauge show? If it's higher than it should be, drain the tank and replace the pressure switch. If it's not unusually high, then replace the pressure relief valve.

DO NOT let that compressor run at too high air pressure! A burst air compressor is a TERRIFIC bomb, and can kill you before you know what happened!

If you aren't getting a buildup of air in the tank, either the tank isn't holding the compressed air or the pump isn't compressing air. Check the unit for leaks, especially at all joints like the tank drain valve, pressure switch, tank check valve and the pressure relief & outlet tubes. If all of these are OK, you'll have to check the pump. Remove the head to check the condition of the valve plate and reed valves. Also check the piston ring and cylinder for damage. You can go to a site like www.ereplacementparts.com to see a great breakdown of your compressor. Most parts you may need are also available there.

When you want full pressure / volume from the tank, you will need to bypass the regulator. Easy task. Drain air from tank. Remove the safety pop valve (usually 1/4 npt thread) and install a tee fitting. Replace the pop valve on one port and install a quick connect on the other giving you full pressure when you need it. Good luck with your projects.

I have a craftsman recon oil 1 hp air compressor 3 gal, I do not have a manuel. It is model number 921.531101. how do i turn it on? how do I use it. how do i hook up the hoze? anything else? thanks...


Hi, Larry, W/D here.
Locate where the electrical cord goes to the compressor (a gray or black box). That is your pressure switch, and has a lever next to it, usually with a red rubber tip on it. Flipping the lever turns it on. To hook up the hose, locate the female hose connection at the regulator. It is either the type where you slide the collar back and insert the air line, or the type where the collar is already back, and locks into place when the hose is pushed in.
The regulator on this model is adjustable; the gauges are separated by a knob between them. The knob allows you to adjust the output pressure. The inner gauge, closest to the compressor, shows the pressure on the tank, and the one closest to where tha hose takes off is the "working" pressure. Don't adjust the pressure unless there's a need to. Between the gauges is a small cylindrical brass piece with a ring in the top of it. This is the pressure relief device. It will open if the compressor fails to shut off when it is supposed to. You don't need to do anything to that either.
If the compressor runs a bit, it will produce moisture from the heat of compression, and the moisture will collect in the tank. It is a good idea to drain the tank down from time-to-time to keep the moisture from rusting out the tank. there is a small valve on the underside of the tank for this purpose. When you know that you are going to use the compressor a lot, you can crack the valve, just a bit, to keep the moisture drained.
This should get you started.
Best regards, --W/D-- Please feel free to rate this solution, and let me know if I can help further.

Will not compress much air and sounds like a vacumn cleaner


sounds like a broken inlet valve, you need to remove the cylinder head and replace the valve plate and gaskets, pay attention to how the plate is installed.

Install reed valves hitachi air compressor need pics


I believe in your model of air compressor, when you take apart the head portion to your compressor you should have four reed valves. When you have it apart, there should be two "grooves" on the bottom "plate" and two "grooves" on the top plate (where the reed valves go). the bottom part is easy (as you should already know) to set in the reed valves, but as i have also found out, as you probably have, that its a little more difficult to line up the other reed valves to thier "grooves" on the upper "plate". What you do to make sure that they stay in place is dab a little oil or grease on the reeds and place them in the upper "plate grooves" and carefully set the upper plate back in place where it goes on the compressor. It will hold them in place long enough to install it on the compressor and the small amount of grease that was there will quickly be burned up with no effect to the opperation to the machine.
Sorry, long winded explanation. hope this helps and if it didnt get to you soon enough i hope it helps out in the future. :-D

Champion vr3-8 auto drain blowing out when compressor turns off


IS YOUR TUBING CLOGGED, PINCHED OFF OR MAYBE DIRT-DOBBER NEST IN IT. THE WATER AND AIR IS SUPPOSED TO COME OUT THE SMALL TUBE POINTING DOWNWARDS BUT SOME EXCESS AIR MAY COME OUT THE SILVER VALVE ON TOP. THIS IS THE EXCESS AIR WHEN IT IS UNLOADING AND THE SILVER VALVE IS BASICALLY A TIMER. YOU CAN ADJUST THE DURATION OF THE BLOW DOWN TIME BY LOOSENING THE THIN JAM NUT AND SCREWING IT IN OR OUT. DO NOT BLOCK THE SMALL TUBING OR PINCH IT SHUT, YOUR COMPRESSOR CANT UNLOAD AND WILL START HARD. DONT REPLACE THE WHOLE DRAIN BECAUSE THIS AUTO DRAIN TAKES A REBUILD KIT THAT COSTS AROUND 20.00 TO 25.00 AND IS VERY SIMPLE TO REBIULD. YOU CAN CONTACT ME FOR PARTS, PRICING AND INFO AT JBRIDGERS@CA-EQUIP.COM OR WWW.CANDAEQUIPMENT.NET
