Just found this thread and am in the same position. Picked up an older KX121-3 and going to be building a boulder wall shortly. When the seller delivered it I hopped in and was monkeying around with it...I had the thumb extended and curled the (empty) bucket into it. He warned me not to do that or I would/could bend the cylinder by putting all that curl force on it while fully extended.
So I have been trying to figure out as I move these boulders around how to curl the bucket once I have the stone picked up...have had a heck of a time trying to back off the thumb at the same rate the bucket is curling.
That is the takeaway from this thread though? that thats what you need to do if you plan on curling when you have something picked up? Or was the takeaway that most modern thumbs will have a relief block so dont worry about it? Or does the relief block not mean you dont need to back off the thumb while curling bucket, but just means you dont need ot be super conservative with doing so (which would result in dropping object)?
How would I know if my thumb has a relief block?
