Tilting the cab back
Turn the two-way valve (2) on the pump (1)
counterclockwise (position B).
While pumping, the pressure which has built up in
the pump will be passed on to the pressure side
of the cylinder (3) and the non-return valve (5) in
the cylinder (3) will be activated simultaneously.
Each stroke of the pump (1) opens the non-return
valve (5).
When the non-return valve (5) in the cylinder
opens, oil can flow back into the pump reservoir
from the cylinder return side.
The cab will move only when the pump is being
operated.
The pressure in the pump and the pipes
consequently drops back to zero at the end of
each pump stroke. The non-return valve (5) will
now close.
The cab will fall downwards on its own a few
centimetres before it is completely secured in the
locks.
This is due to the fact that the piston of the
cylinder is in a position which allows a leak-off
connection (4) between the areas above and
below the cylinder piston.
The warning symbol "cab lock open" on the
instrument panel goes out as soon as the cab
locks are engaged.
