TX200 safety button doesn't function properly.

[nced]

I have a TX200 needing some maintenance work. When shooting over the chrony I noticed that the safety is always set to fire after cocking. The gun does shoot reliably, however the safety is always in the firing position.

I thought I'd get some expert opinions about what to look for before messing with the trigger group myself.

Thanks in advance for any help!

Ed, this is pretty much just the way the TX 200 operates.  I don't know Weihrauch but Air Arms and Diana automatically set the safety when cocked.  Once the safety on Air Arms is turned off you cannot turn it back on.  You must recock the gun.  You may download the manual:

My TX200 safety did not reliably reset unless I really bottomed out the cocking action.  After I installed a slightly larger cocking shoe, the problem disappeared.

Yup a TOO SHORT piston seal is one cause ... the Comp chamber pushing on piston during cocking is reliant upon the piston getting pushed far enough reward to activate the safety while cocking the action.
When latch rod of piston JUST MOVES far enough reward to cock action, but NOT far enough to engage safety this issue occurs.

Spring coil bind or a worn shoe can also prevent piston / latch rod from being moved far enough rearward.

Forearm screws can be hitting the cocking arm causing the problem. Loosen them a little then test.

Sorry, I didn't state the problem correctly in the origional post.
This particular TX200 the safety button is "always in shooting mode" and doesn't reset when cocking.

Where did you get the "slightly larger cocking shoe"?
I checked out Pyramyd Air and $19.99 + $7.99 for shipping ($27.98 total) seems exorbitant for such a small part!

Thanks for the help! Now I a couple starting points to investigate. I'm pretty knowledgeable about HW springers but Air Arms....not so much!

That item from Pyramid Air is just an OEM replacement.  The shoe I installed was an aftermarket oversized part that required fitting.  I believe I got it from Air Rifle Headquarters.  Search GTA for "TX200 cocking shoe" and you should find some information that may be helpful to you.

I have the same issue on my tx200. Good to hear all the insight given here. Thanks folks.

Wow !!

I wish mine behaved that way ...   

I hate automatic "safetys"

Sometimes, just a drop of oil will rectify the problem.

Maybe...   The TX200 owners' manual says you should lubricate the safety button every shooting session: "A couple of drops of oil must be applied to the safety catch button regularly to ensure safe operation. Preferably just before each shooting session."

LOL.....now THAT would be the preferred fix! 
The cocking lever of the gun and "connected parts" does squeek and squawk when returning the lever to the "catch" so perhaps the issue is simple lack of maintenance. The gun does seem to shoot strong however since it's sending 7.9 grain CPLs over the sensors at 915ish fps.

Maybe the safety spring broke. Did you pull the trigger unit out and use the piston to set the trigger to see if the safety will set? If it is the shoe and you can’t find an oversized shoe you could just braze the cocking side of the shoe and file to fit. Had to do this to mine because of a loose lock up but other side of the shoe. Hope you get it fixed.

Haven't pulled the TX apart yet because I was waiting on feedback. Thanks for the tip and I do hope that the issue is simply a "sticky safety".

Hi there,
This afternoon I took the trigger out and examined the safety on my TX200 HC.
I found that the safety button was not engaging correctly.
The whole trigger mechanism was oily but I did not go inside (save that for another day). Upon inspection the hole that the safety fitted was a little dirty but not enough to prevent correct engagement.
It turned out that by simply rotating the button on its spindle was all that was required. In its original direction it was difficult to push into its hole. Turn it and it was really free.
I put it back to gether in the free location and it now works every time.
My suggestion is that rather than take it apart try grabbing the safety button and turning it 90 degrees or how ever far it needs to go to be free.
Hopefully this will resolve it.
Kindest regards,

Nicholas

Update on TX200 safety issue...........
The safety functioned properly after the "end plug" was removed and the sear cocked. Safety popped out normally and the trigger group would function normally after depressing the safety. Using the good response I received I checked the fit of the cocking plate to the corresponding recess and indeed there was a lot of slop.......

Will try shimming up the back of the plate and tese if the added stroke will actuate the safety properly.

[Paul E]

I didn’t have a lot of luck getting the sim to stay in spot but the braze worked perfect. Good luck.

If anyone is interested, this is the post on the lockup issue: 

http://www.airgunforum.co.uk/forums/showthread.php/165327-The-TX200-cocking-shoe-cylinder-lock-up-issue

My original shoe required 0.020" of shim stock inside the front of the shoe to achieve proper lockup.  After installing the Air Rifle Headquarters machined steel screw no shim was required.
