5.4 Assembly of body and sensor
Place the bellows follower [13], which is packaged with the
body, into the bellows [14] with its flat surface facing downward
and then screw it into the lower surface of the body [1] by the
ring [15].
It makes the assembly easier to loosen the handle [12] to
direction of the “L” position. Be sure not to lose the bellows
follower because the product does not function properly without
it.
