Note
While the tool head is testing make sure that the 2 small fans are on. When the actuators engage make sure that the PP-FP0244 slides bottom out on PP-FP0245 and no wires are getting pinched. Check that the motor on the side that is down is turning once the tool head is heated up. Once both motors have cycled the blower fan will kick in to cool down the tool head. Check that the blower fan is working.
