BELARUS-1221.2/1221 В .2/1221.3 Description and opera-
tion
128
In case of raising (“popping”) of the agri-
cultural implement when passing
through the pressed soil areas gashes,
deepen the agricultural implement by
pressing the handle (7) more downward.
On releasing the handle (7) it will return
to the fixed position of lowering. When it
will be done, the agricultural implement
reaches to mode of the preliminary
specified depth set by the handle (4).
To raise the agricultural implement, shift
the handle (7) to the upper position.
When lifting the implement, the indicator
(5) lights up.
ATTENTION! To avoid the failure of
the HLL pump, it is prohibited to oper-
ate the tractor unless the indicator (5)
goes out after lifting the implement.
It is necessary to know the following pe-
culiarities of starting the work with the
rear hitch linkage control system:
1. On starting the engine, the diagnostic
indicator (8) lights up to indicate the
serviceability and locking of the con-
trol system;
2. To unlock the system, it is necessary
to set the handle (7) once to the
working position (lifting or lowering).
When it will be done, the diagnostics
indicator (8) shall go out.
3. After unlocking the system when
switching on the same for the first
time, the automatic limitation of the
speed of lifting of the rear hitch link-
age is provided for the safety rea-
sons. Setting the lever (7) to the “Lift-
ing” position repeatedly disables the
limitation of the lifting speed.
4. The lifting and lowering of the rear
hitch linkage by means of the remote
control buttons on the fenders of the
rear wheels can be performed in any
control modes (the handles can be
set to arbitrary position). In this case,
the cab control system is blocked.
WARNING: When using the remote
control units, never stand between the
tractor and the implement ganged. To
avoid accidents, it is strictly prohibited
to use the buttons of mechanical
movement of the regulator solenoid
valves.
The work with the control system shall
be started in the sequence described in
paragraphs 2 and 3.
ATTENTION! To avoid more deepen-
ing of the agricultural implement, in
case of emergency stop of the tractor
the control handle (7) shall be set to
the “Neutral” position. After starting
the movement, shift the handle to the
“lowering” position (the agricultural
implement will e deepened to the pre-
liminarily set depth).
In addition to the above functions, the
electronic control system of the RHL is
provided with the “damping” mode
(damping of oscillations of the mounted
agricultural implement in the transporta-
tion mode).
The damping mode shall be enabled in
the following order:
• Set the handle (7) to the “lifting” posi-
tion (when it will be done, the RHL
will be lifted to the top position and
disengaged automatically);
• Press the “Dampind” button (9) (when
it will be done, the RHL will be low-
ered from the top position by 3% from
the full stroke of the RHL).
ATTENTION!
1. The “Damping” mode can be only en-
abled, when the handle (7) is set to the
“Lifting” position.
2. When performing he field works
(ploughing, cultivation, etc.), the “Damp-
ing” mode shall be disabled.
