Help before I kill myself or some else
I found the female connecter to the air system in the generator compartment and decided to put some air in my granddaughters bike tire. When I tried to insert a male end it required a bit of force. I got it part way in and was hit with a blast of high pressure air which sent the male end flying.
What am I doing wrong? Is there a lever to close off the system? Should I completely let the air out and re-pressurize? Any help would be appreciated.

There are a couple of different male connectors. You probably have the wrong one.
Look at them closely below and see the difference.

Check the max pressure the bike tire can take and also check what the pressure is coming from the system to that male fitting. You ought to have an adjustable regulator with input (tank) pressure reading on one gauge and oultet-line pressure on the other. Set the output to less than the bike tire's max to start with, then increase as needed.
With a compressed air set-up it's very easy to blow the bike tire to bits in a couple of seconds.

Let some presure out of the air tanks. There is some where around 100 to 125, but also let all the presure out then check to make sure you have the correct quick connectfitting.

I like the idea of a pressure regulator and gauge. Can these be obtained at any big box store or on line? Can you shoot me a link or photo?
Thanks

seeg,
Were you trying to insert the air hose fitting with the coach or generator running?
If so try it with the coach & generator turned off. After insertion, start the coach up.

Also remember there are gas QC (quick connect) as well as Air QC. And neither the two shall fit... I tried to inflate my kids swim toy with propane, thankfully the air hose was too small for the propane QC. Ya, bad dad!

Biggest thing is making sure that you AIR connectors; GAS connectors are different and as someone already mentioned, they are NOT compatible. It took me several mistakes until I finally got it right.
At 125+ lbs of pressure you are playing with fire. Connecting/disconnecting even the correct hose fittings can lose you a couple of front teeth. Just make SURE you have a VERY firm grip on the hose coupling you are trying to insert.
Otherwise it could be shot outta there with about the same force as a 45 calibre bullet. Well, maybe not quite that bad, but you get the idea.
Boowho??

The coupler has a type of a sleeve that needs to be pushed back as you insert the fitting. When the fitting slips in let go of the sleeve to the coupler and you should be good to go. Will be easier to install when the air pressure is on the low side.

I have the one second from the right, but the only difference in mine and yours is that mine has female thread and yours has male threads it seems.
If you have not yet, you may find one tie wrapped near your connector. Typically there is one there from the factory for use by tow truck drivers if needed.
So far, it sounds like it may be your method of plugging in may need tweaking. It takes two hands to do it right. Hold the collar/sleeve on your coach's connector back with one hand while plugging in your adapter with the other hand.
Other suggestions to NOT start up the coach is a good idea. You do not need 125 lb air to fill up a bike tire and you should be very careful. It will probably only take a fraction of a second to fill that tire, and just a little more to blow it up.

I haven't done it yet, but I will install a ball valve upstream of the quick connect coming off the coach. This will enable me to bleed pressure downstream.

You should be able to pickup a regulator and all the needed fittings at the big home centers/tractor supply/northern tools/etc. I have one on my compressor in the garage and it makes it easy to adapt the pressure to different tools and uses.

I installed a ball valve both for the pressure prob you had and as a redundancy incase the quick connect ever leaked. Here is the link for the thread with a pic. Once I am done I turn the valve off, put the air chuck against the corner of the generator frame to bleed of the pressure in the line and then diconnect.

Update. Thanks for the many suggestions. I got my wife to pump the brakes and reduced the air pressure to around 75 and then inserted the male connector w/o a problem. I purchaded a ball valve at Home Depot and put a male quick connect on one end and a female quick connect on the other and connected the entire assembly to the female fitting on the coach.. With the ball valve closed there is no pressure to the last female quick connect and I can insert a male end before adding pressurized air. I alsobought a reulator for controlling the pressure down stream. Thanks again for all the help.
