“Floating” mode on section No.1 is switched on by shifting joystick 2 handle for-
ward against stop and by holding it in this position for more than two seconds. Switching
on of “floating” mode on section No.2 is carried out by shifting joystick 2 handle to the
right against stop and by holding it in this position for more than two seconds. “Floating”
mode on section No.3 is switched on by shifting joystick 4 handle forward against stop and
by holding it in this position for more than two seconds. Switching on of “floating” mode on
section No.4 is carried out by shifting joystick 4 handle to the right against stop and by
holding it in this position for more than two seconds. “Floating” mode switching on is indi-
cated by three-time flashing of two annunciators on panel 3 along the axis of the corre-
sponding section. This pair of annunciators continues to glow until the hydraulic distributive
valve sections go out of “floating” mode.
The set “floating” mode is memorized by the joystick and remains switched on after
shifting the joystick handle into neutral position. To go out of “floating” mode, it is required
to shift the handle of the corresponding joystick from the neutral position along the control
axis for this hydraulic distributive valve section.
To set a fixed flow on the hydraulic distributive valve section, it is necessary to set
the handle of the corresponding joystick into the position of the required flow and, holding
it in this position, press button 1 (or 5) on the joystick handle. Fixed flow switching on is
indicated by three-time flashing of the corresponding annunciator towards the set flow.
This annunciator continues to glow until the hydraulic distributive valve sections go out of
fixed flow mode.
After releasing the button and shifting the joystick handle into neutral, the joystick
memorizes the set flow. To go out of this mode, it is required to deflect the joystick handle
to the side of the set control for the corresponding section of the hydraulic distributive
valve with the fixed flow and press button 1 (or 5). To set a new fixed flow, it is required to
return the joystick handle into the neutral position and then carry out setting of flow
amount, as described above.
