Turn the two-way valve (2) on the pump (1) to
the right (position A).
While pumping, pressure will build up in both
pipes leading to the lifting cylinder (3) and the
cab locks (6). Any overpressure in the system is
returned to the reservoir via the safety valve (7).
At each pump stroke, the non-return valve (5)
opens. Oil will now flow underneath the piston of
the lifting cylinder (3). The pressure in the pipes
drops at the end of each pump stroke. As a
result, the non-return valve (5) closes.
In spite of the fact that the oil pressure above
and below the cylinder piston is the same, the
cylinder is pumped out, so that the cab is tilted.
This differential mechanism is based on the
effect of pressure on two different surfaces. The
resulting force is the pressure in the system
which is applied to the surface of the plunger
cross section.
Once it has passed top dead centre, the cab will
fall into the full tilt position on its own. Pumping
is not necessary during this.
