21.4.15 Hydraulic function 5
When the driver actuates the hydraulic lever R15, voltage (3.7-6.7 V or
3.7-0.66 V) is fed to A5, which opens the direction valves Y16/Y17 and
sends a signal to the frequency inverter A2. Pump motor M3 starts and
pumps oil to the extra function.

21.4.16 Cab tilt
The driver selects the function by pressing switch S44, which sends a
signal to A5 and lamp 44 lights up. When the forks rise to the main lift
range, switch S45 closes and a signal is sent to A5. Directional valve
Y20 is fed voltage by A5 when cab tilting is to take place. However, the
hydraulic lever must be activated more than 50%. Tilting is by around
15 degrees.
If the truck has pulse counter U10, A5 receives information on the posi-
tion of the forks. At the programmed height, the cab will begin to tilt.
When the forks are lowered and reach the pre-programmed height
again or come down to the free lift range, the cab tilts back as A5 sends
a signal to direction valve Y21 to open. When lowering too, the hydrau-
lic lever must be activated more than 50%.
As soon as the driver releases the hydraulic levers, the tilting and the
forks' lifting/lowering movement stops.
The cab can be lowered manually if the driver presses switch S44 for
momentary mode. A5 is fed voltage and keeps direction valve Y21
open as long as the button is depressed.
