Operation

When the cut wood hits the
sensor in the splitting chute,
the other end of the release
lever lifts up, and the joint
lever that controls the valve
is pushed to the right, thrust
by the spring.
The splitting
starts as the joint lever
moves to the right.
As the splitting cylinder/beam approaches the splitting
blade, the turning rod attached to the splitting beam will
swing the turning lever to its extreme right position.
Thus the valve joint lever goes to its extreme left
position, thrust by the spring.

The splitting release lever
returns to its down

splitting movement.
With the turning lever in

However, the joint lever
stops against the splitting
release lever, which has
dropped down, and the
joint lever stays in its
centre position.
