Einhell BT-SB 200 problem!

[arvacon]

Good morning from Greece and congratulations for this very useful forum.

I know that this is just my first post and I should not start "from the deep" problems, but right now I have a very serious trouble with the Einhell BT-SB 200 bandsaw that I just received it yesterday.
I have only 10 days to return the product, but I don't know from when these start to count, so I need hurry in case to see what its the best to do about my problem.
The problem is common and as I have seen you have discuss this lot of times here, I have also find your suggestions about how to solve most of the problems, but I just want a second opinion before I take my choice.
Of course we talk about vibration problem, but from a totally new and unused bandsaw, as I just putted that out from the box. I have not move or change anything, I didn't aligned something, I just plugged it in the power socket and turned it on and that's the results.. Totally disappointed from what I see and check. If you have the patience to see the whole video, you will see that I have take some measurements with my mitutoyo dial indicators (in metric system), around the middle of the video. You will notice that the wheels seems to have around 0,6mm difference at their side way. At the top it is about 0.2mm if I remember well, but it is from the rubber part, it seems thicker in some points (probably from long time in stock?)..
Thats the video I recorded.



I really don't know if I should keep it and fix it or send it back. I hate to buy a new tool and to have this kind of problems, but because here is Greece and sometimes the representatives, are making you have more problems than solving them, I would be happy if I could hear a nice solution for fixing this problem.
I know this is not an expensive bandsaw, it is just a chinese with German name and it costs just 110 euros, but I was not expecting it would had so serious problems..
I am familiar with the metal machines, I own a metal lathe and lot of other metal machines, but this is my first wood machine, so I didn't know what to expect.. I was thinking, if I remove the wheels and put them to my lathe, then turning a part of its side and making it straight, then if I also balance it and was trying to do something also with the rubber, would I solve the problem, or I would just loosing the guarantee and the rights for return?
I wish I had not buy it and just had buy the Metabo bas 260 swift that it seems a very good machine, but money is a really problem for me right now, but in case I return it, I will keep the money until to buy the Metabo..
I wish we can find a solution without need send this back, as I live in a village and I must send this back to Athens, so that means cost in days of delay and money for shipping, as they say that if you return something, you pay the shipping..


I don't have so much time as I think I must have return it until Monday or later until Tuesday, so any advice will be very helpful until that time.

Sorry for my bad english and thanks for your time to read my long msg.
I hope my video to shows everything I can't describe well in english!

I forgot mentioned that it seems so noisy, and the noise doesn't come from the motor, but from the wheels and sometimes the metal noise is coming from the blade's vibrations, as it touches the guides.
The guides of course needs to aligned, as they are too much open right now, but that has nothing to do with the noise that the wheels creates.
Is the wheel's noise the normal noise they should have?

Perhaps an option is to keep the machine and file a warranty claim for the wheel not running true and causing excessive vibration. Most of the machines of that class do not have a factory service person that can go to a location and check on the machine. They will usually just send replacement parts for those that are causing problems for you.
So, if they send you better parts they will be easy to change and the fix the problems. If the new parts are not better, you are fortunate to have metal working machinery available. You can set the wheel up in a mill or lathe and rebuild the hub so the rim will run true.

Actually today I removed the blade and I checked the upper wheel for balance. Guess what, it is not balanced correctly
Of course the down wheel is mess, but you are right my friend. I think that's a good way to go, so I will call them today to see if they will send me any replacement part, otherwise I will try to repair the ones it has now or make new ones and avoid the shipping charges or/and fights with them..
But I am pretty sure that they will not send any replacement part, they will just ask me to send the whole machine back at their central, to check it by their technician.. We will see, I will inform you later in the day, when the stores open, as now here is 6am!
Yep, I am batman or some friends call me vampire (insomniac) , lol !

This is a new video I recorded yesterday, by removing the blade and the rubber from the wheel.

Thanks for your reply, it gives me courage to keep it

When I looked at the total run out I did not think the little counterweights would be adequate to correct the out of balance situation. The wheels look like the die cast part was not in the machine fixture properly when they bored the hub or the die castings are badly warped.

Have a good day. It is time for bed here.

The lathe will show us the truth. Unfortunately my lathe can't handle the 20cm diameter of the wheels, but for good luck a friend of mine has a bigger lathe, so I will visit him today at evening to try do some repairing of them.

I will go for a nap too. Have a good night pal.
