MOTOR SCREWING ROTATES NONSTOP
When the rotating pin (6 part number 4151500) is broken and you replace it, the motor may rotate continuously,
which means that the shaft (13 part number 3761300) is too long; in this case it will have to be shortened by a few
tenths to obtain the closure of the ball (14 part number 3096900). When the air is on, the shaft shall have no end
oat.
MOTOR UNSCREWING DOES NOT ROTATE
Unlike the situation above, the shaft is too short and it has to be replaced with a new one, tting it without end oat,
with the air on, in order to obtain the closure of the ball (14 part number 3096900).
