I installed a thumb and I can't get the settings right. It's a progressive lever thumb.
I'm trying to set it so that the bucket will overpower the thumb to avoid damage.
My settings options are:
Attachment relief valve: Both disabled / attachment relief is enabled / breaker relief is enabled
Attachment selector valve: C/V or O/T
Aux flow combiner valve: enabled / disabled
Attachment relief pressure: min 10mpa / max 36mpa
No matter what I do with relief setting setting the selector valve to O/T makes the thumb so weak its useless, and setting it to C/V makes it so strong it will overpower the bucket cylinder.
Does anyone have experience installing thumbs on these machines?
