ATTENTION: AUTOMATIC ACTIVATION OF FDA DRIVE IRRESPECTIVE OF THE SET
MODE (INCLUDING THE MODE "FDA OFF"), TAKES PLACE WHEN PRESSING THE
INTERCONNECTED BRAKE PEDALS!
ATTENTION: WHEN OPERATING ON ROADS WITH HARD SURFACE, IT IS RE-
QUIRED TO DISENGAGE THE FDA DRIVE IN ORDER TO PREVENT INCREASED
WEAR OF FRONT WHEEL TIRES!
ATTENTION: VIOLATION OF RULES FOR USING FDA DRIVE OPERATION MODES
MAY RESULT IN BREAKDOWN OF FDA PARTS AND OTHER PARTS OF TRANSMIS-
SION!
TRACTOR OPERATION WITH FDA DRIVE ENGAGED WHEN THE TRAVELLING
SPEED IS ABOVE 13 KM/H IS FORBIDDEN!
2.15.4 Rear axle differential lock control
The rear axle differential lock (DL) is controlled with switch 5 (figure 2.15.1). The indication
of rear axle DL operation is performed by annunciator 4.
Switch 5 has three positions:
"DL off" - middle fixed;
"DL automatic control" – upper fixed;
"DL positive activation" – lower non-fixed.
To avoid increased wear of rear wheel tires and rear axle DL, use the mode "DL off" when
moving on roads with hard surface with the travelling speed above 13 km/h.
The mode "DL automatic control" with guide wheel position corresponding to linear move-
ment, engages the rear axle DL and annunciator 4 goes off.
The real axle DL is disengaged automatically when the guide wheels turn to the angle
above 13° or when any or both brake pedals are depressed. In this case annunciator 4
goes out.
The mode "DL automatic control" is disengaged by setting switch 5 into the position "DL
off". Annunciator 4 goes out.
Use the mode "DL automatic control" when carrying out operations with significant relative
skidding of rear wheels.
If rear axle DL short-time positive activation is required irrespective of front wheel turning
angle, press switch 5 and hold it pressed in the position "DL positive activation". The rear
axle DL remains engaged during the time of holding switch 5 pressed. Simultaneously an-
nunciator 4 goes off. When switch 5 is released, the RADL returns to its initial (disen-
gaged) state and annunciator 4 goes out.
TRACTOR OPERATION WITH RADL ENGAGED WHEN THE TRAVELLING SPEED IS
ABOVE 13 KM/H IS FORBIDDEN!
TRACTOR OPERATION ON ROADS WITH HARD SURFACE WITH RADL CONSTANT-
LY ENGAGED IS FORBIDDEN!
2.15.5 Annunciation of oil emergency temperature in the hydraulic lift linkage
The annunciator of oil emergency temperature in the HLL lights up when oil tem-
perature in the HLL tank exceeds the permissible limit.
The annunciator of oil emergency temperature in the HLL can be mounted in the following
places:
- element 7 (figure 2.15.1) – on tractors with GB 16x8 with FPTO not mounted;
- element 8 – on tractors with GB 24x12 and with GB 16x8 with FPTO mounted.
