unscrew the four screws on the drop arm device and press them down (normally attach the arm
lock parts is ok),at last , tightening the screw and circle dropout test.
Q7:The arm won’t operate when power on.
Reasons:
1. The drop arm device is putting too high, raising the arm up by manual, but arm lock will push
drop arm device bottom, but solenoid can’t reach to the position which attract plate.
2.The drop arm device is putting too low, raising the arm up by manual, the arm lock will push
drop arm device bottom, after solenoid attract plate, the arm haven’t be fixed to the balance
