WHEN THE TILT CONTROL LEVER IS IN THE FORWARD POSITION
3)
When the tilt control lever is pushed forward, the spool on the second block is moved to tilt forward
position.
The oil from hydraulic gear pump(1) flows into main control valve (2) and then goes to the large

The oil at the small chamber of tilt cylinder(5) returns to hydraulic tank(11) at the same time.
When this happens, the mast tilt forward.
