Hello all people,

I have purchased a Old Okuma LB 15 twin turret turning machine.
When I have powered on theis machine, There is alarm appeared on screen " ALARM 206 A Shear pin 4"
I have checked the alram list in the machine manuls, but there is no 200 series alarms in those manuls.

Does any body know what type of alarm is this? and how can i get rid of that?

Please help me.

regards.
