Disable the parking brake (parking brake
lever PUSH).
Gradually release the drain pedal and start moving. Gears shall be changed by PUSHING
(upshift) and PULLING (downshift) the gear change lever. In doing so, do not depress the
drain pedal.
After the engine start-up make sure that all tractor systems are functioning.
Check the operation of light and sound signaling, braking system, hydraulic systems for
steering control and of the linkage, make sure of the absence of faults.
Check the readings of indicating instruments.
Oil pressure in the GB hydraulic system at the engine crankshaft speed of 900-1800 RPM
shall be 1.0-1.2 MPa (10-12 kgf/cm
2
) for K-744R1, K-744R2 tractors and 1.1-1.3 MPa (11-13
kgf/cm
2
) K-744R3, K-744R4 tractors. Oil pressure growth at each gear shall be rapid. The
pressure on neutral gear and at engagement of synchroniser brakes shall not be less than on
transmission gears.
Set the pressure in tyres depending upon the kind of work being executed (see Table 4 of
Section 6).
Perform taking off as follows:
–
set the handle for manual fuel feed into the position corresponding to the mini-
mum engine crankshaft speed;
–
set the gear change lever into position ENGAGEMENT OF SYNCHRONISER
BRAKES;
–
depending upon the value of load on the hook, type and conditions of the forth-
coming operation, select the GB operating mode.
In case of difficulties in the engagement of modes and reverse gear, it is necessary to press
and release the drain pedal or make a movement by the steering wheel. In case of difficulties
in the engagement of rear axle, it is necessary to put the tractor on a horizontal ground with
semi-frames in straight position;
–
– set the gear change lever to position "N";
