Bandsaw Tension
I have just picked up and assembled a new 4300 bandsaw from Carbatec. I have read the manual but nothing is said how tight to tighten the blade. There is a scale but nothing refers to the blade width or tension required.
Is this a copy of a macine where the other reseller has a better manual that I could download?
Looking for some general guidelines from the wise please.

1" blades - as high a "ting" as you can get without bending anything.
3/4" - higher "ting" than 1"
1/2" - a lot higher ting than 3/4"
1/4" - cat with b...s caught in vice "ting".
1/8" as high a "ting" as you can get without snapping the blade.
Now hows that for a set of scientific tensions.

I have found that if you open the top door, reach inside very carefully with a pair of strong pliers, firmly grab the yellow indicator, and then rip it fully from its mounting, it will do wonders for your expectations.
I tighten the blade carefully, a bit at a time, watching how it tracks as I go. This way I can change the tracking and get it reasonably tight as I go. I know the general concensus is to tighten the bejeesus outta the thing, but really, all you need is it tight enough so that the workpiece has a nice vertical cut from base to top. If the cut appears bowed then you have insufficient tension.
This will apply to any blade, although, as has been said already by Termite, the smaller the blade the tighter it should be. Tension relates to the individual blade, so ensure you check it after replacing a blade with the same size.

If the blade was slack enough to cause a bowed cut then I doubt it would be tight enough to be driven through the timber, this is assuming that you lower the top guide to suit the timber thickness.

With my bandsaw, a MJ 344C with a 2950mm blade, has a approx 25mm dia coil spring under the tension adjuster. I assume this is to absorb any shocks from maybe a woodchip getting caught between the blade & the wheel.
Trouble is, to get anywhere near the required tension to get any sort of 'ting' as opposed to a 'blaht', that spring is compressed fully removing any sort of shock absorbsion.
Also, I need to screw it up very tight to stop the blade 'slapping' inside the frame.
Are both these symptons normal?

Thanks ..... I think
Thanks to all who replied. It seems as though this is a hot topic.
I think I like the idea of watching how the cut goes. If it is going wrong and I have little control. Wind up the tension.
So far I have only being cutting up scrap and had no problems withbowing or barrelling. The cuts have been relatively straight. Just operator practice is needed.
I will monitor how I go over the comming weeks.
Thanks once again. I knew you would all have the answers.
Regards
