Hi,
I got myself an older Amada HFA-250 bandsaw and all is good but the rear vise. In manual mode I can clamp the front and rear with no problems. Once I place the machine in automatic mode,
the rear vise moves back to clamp for the next cut but starts going back and forth searching for the right length and eventually giving an E-004 error code. I have replaced the encoder but still
its doing the same thing. Any help would be appreciated.

Thank You!
 
good afternoon!

I too am having this issue on the exact machine. was wondering if you found a solution for the rear vis not opening.

if you dont already have it i have the operators and maintenance manual for this model the 250w, 400 and the 400w.

Any leads will be helpful thanks in advance.
 
Sorry. Been using the saw in manual mode. We did replace the encoder and the problem is still there. Only other part is the bi-directional hydraulic solinoid valve, and they want around $4000 for that. Cant find anyone to repair the unit.
