I received the RWS 34 Meisterschutze from Umarex and just tried it today.
I shot 4-5 pellets so far.
There is a loud/heavy grinding noise when cocking the rifle.
The noise seems to be caused by the cocking lever/arm or the mainspring/piston rubbing against the mainspring tube.
Cocking is also much harder and takes much more force than it should.
This grinding noise seems to be a common enough occurrence with the 34 according to various threads.
I have also recently received an RWS 460 and RWS 54 which are great.
The RWS 34 is the only one which has quality issues.
I sent Umarex an email asking them what I can do.
Did any of you have this issue and if yes what did you do to solve it?
-
My 34 was fine until it broke the spring. This was after over 3000 shots. When I put in the new spring it started making a nasty grinding noise. What I did was sand down the slot were the arm rides and now it is smooth as can be.
-
It probably will have to come apart for a deburr and lube.
-
Did you try to cock it out of the stock?
-
A bit of grease along the cocking slot and a bit more spread on the spring may help. If that doesn't do it disassembly of the internals is probably in order. This WILL void any warranty on the gun so make sure it's working well otherwise. Once disassembled you can smooth the cocking slot as required. It will probably help to sleeve the piston with plastic or aluminum while in there.

This is a new Diana air rifle.
I would expect a Diana air rifle to work when new out of the box.
I will return it and ask Umarex to provide a shipping label.
Anybody knows the contact info for the Umarex guy posting here (JB ...)?

I thought you already emailed Umarex? I'd wait to hear back... Remember you got that gun on a really good deal (168 bucks) and they may not be able to offer a replacement. It might be a refund instead. Depending on what troubleshooting or repair advice they offer, after that you might see if its something you could repair yourself or by someone else otherwise if you go looking for another D34 to replace it, the cheapest offering is at guncorp which runs about 236 after shipping and tax.
-
There were several here on GTA that missed out on the Umarex deal. One of them might take it off your hands.

I have a .177 38 tuned by John in Pa . A safe queen I picked up unused, that I might be pushed into doing a swap +$. Or maybe buy outright.

Hector thank you for your advice of shooting more pellets to get the rifle to its full potential.
The grinding noise was made when the piece of metal attached to the cocking lever that is inside the mainspring tube rubbed again the mainspring tube.
I lubed the area between that piece and the mainspring tube with 30w non detergent mineral oil.
Most of the grinding noise/feel stopped after that.
I installed the scope and managed to decapitate the screw that attaches the 11mm rail to the mainspring tube.
The screw head was cut off clean because the recoil cause the mount to move against the screw.
It seems that the mount and stop pins was not installed properly the first time.
I am sure many other people did that before so it seems that this is a design problem.
They should have used a screw buried under the surface of the scope mount.
Right now after about 100 shots the accuracy and shot cycle got better.
Will report more after 200-300 shots.

Like said here?
"He says: “Note that the large-headed screw at the rear of the scope rail is NOT a scope stop. If you try to use it in that way, it will shear off."

What does this screw do , there is one on my 48 and on my 460.
I thought it was a scope stop ???
-
I believe it is for a rear peep sight that was used at one time. Or so I heard
-
Maybe, that guy said it did not hold anything and just removed it???
There must of been some intention for it or why have it to start?
-
After almost 200 pellets and some oil in the area which was rubbing against the mainspring the grinding noise/feel is almost gone.
-
It's almost funny how we go in circles at times.
Hey, it's all in the fun!
The rear "filister head" screw at the rear end of the rail is NOT a scope stop. It does NOT attach the rail to the mechanisms tube.
Back in the days when DIANA started making airguns capable of doing well enough that "diopter" sights were effective, there was a sight that locked into the head of that screw. That screw is a 3 mm's screw (less than 1/8"), so the head is NOT illustrative of what lies underneath.
That rear hole, with another one tapped adequately, do work to mount a specially made peep:

It has been retained as a "trademark" characteristic. When questioned, most of the wholesalers requested to keep it.
I am glad Pinguinu's gun is settling down give it a few hundred more and you will have a sweet shooter for MANY years to come.
To all: keep well and shoot straight!
