Question about Air Tools & Compressors

1 Answer

Air compressor not working

First off, I have no meaningful experience with air compressors, so I'm not really sure what I'd look at in the first place

I got this new jump start/air compressor machine, and I wanted to pump some bike tires up with it. However, while the motor inside it sounds like it's working fast enough, I get no air from it. If I hook connect the valve to a tire, however, while it won't fill it I will get a pressure reading which dismisses the probability of a clog somewhere.

The motor also makes a rhythmic clunking sound every second or so.

I tried waiting for the device's built-in battery to reach full charge in case simply plugging it in wasn't enough, but it didn't help.

Where should I begin looking?

    Well, I cracked it open (rather carefully as not to electrocute myself) and there were no leaks. The clunking sound is the piston, and after watching it (the crankshaft has an opening on one side) it seems that it only does one full rotation every second while the engine spins rather freely.

    The large gear (assuming that's a clutch?) the motor spins, spins rather freely. Is it possible the clutch isn't doing it's job right and is there any way to fix it?

    Okay, I tried taking the piston chamber apart, and checking it. I wanted to see if a clog could be the cause, so I left the chamber head loose. Of course it lost compression, but the crankshaft began to speed up to an appropriate speed.

    I think there may be a clog somewhere, but I'm not sure where.

    I can't return it, I recieved the thing as a gift (strange gift, lol).I checked to make sure the air outlet was fine before opening it.

    I forgot to update on this, but a few hours after posting my last comment I cracked the cylinder open and cleaned the outlet valve a little, and after reassembly the crankshaft began to spin faster and I could feel the performance improvement at the end of the hose as air. However, it's not powerful enough to pump anything up. It seizes up and is unable to pump once connected.

    I tried cleaning it a little more, but reaped no improvement this time.

Check were the hose mount's to the motor to see if it cracked or torn to see if the air is comming out there instead .

    if this is a new product'i would return it for the warranty.if not there are 2 things you can try.1"stcheck to see that the air out let is operating properly by sticking a nail or something in the end to see iff the air is being released at that end if so then it sounds like a manufacturing fault and should be returned for exchanged.

Where can i mount firestone compressor for rear spring air bag kit on mitsubushi outlander?

Improve the FixYa experience for everyone by voting. I want you to let me know if the solution(s) suggested were of any value. Constructive criticism is welcomed.


I'm Ben and -- hopefully -- I can provide some meaningful assistance.

You can mount the compressor in any spot that avoids damage to the valve. I personally prefer under the hood in some out-of-the way place like in proximity to the horn. The Firestone instructions list several possible locations. CLICK HERE FOR THE INSTALLATION INSTRUCTIONS

I have the Porter Cable Cable Brad Nailer and Compressor Combo Kit CFBN125A, and sparks are flying like crazy from where the motor brushes make contact when running. I have wiped down the rotor in an...

In my experience, these are really throw away compressors. I have had several. You might get the parts ... however, if the brushes are arcing, the armature is probably damaged. If that is the case, the motor has probably run hot. As such, the field may well be heat damaged now ... ok, so replace the motor right? Will cost you about $100.00 for parts ... add your labor ... even if that is $0.00, when you are all done, you will have a five year old compressor (worn sleeve and piston? worn reed valves) with a nice new motor.

That was my experience. I replaced the thing. I only use this little compressor at remote places. I have a larger, main compressor for other work.

Compressor really doesn"t take oil

if this is a belt drive system, the oil fill is on the base of the compressor side, it is usually a small knob with two bumps on it, designed to open with the fingers or a pair of pliers. you don't pour oil in the breather pipe, some folks put a little oil in the air hose, but its better to put oil in the tool.

Lost my instruction book for my MaxAir compressor . Is there some place I can download one for free off the internet?

Here is a couple of links one is for MaxAir. The other to a site that might have the manual you need. I can't really check any where else without your model #.
I'm not even sure if this is the MaxAir compressor. This MaxAir site is for heavy duty commercial grade compressors.

Let me know if you can't find it and include the model # of your comp.
Hope this helps.

Compressor Fan stop working

Do you have a meter? Either the fan is bad or the capacitor is bad. Ohm out the fan and then the capacitor. Be sure you take the disconnect out of the electrical box on the side of the house and or trip the breaker off. The capacitor is a dual run one side operates the compressor and one side operates the fan. I would really bet on the capacitor being bad. Have seen that a lot in my experience. Be sure to make note of the wiring of the capacitor before you take it out to check and if you are not sure how to check it take it to the parts house and they can check it.
