3.2.3 Start of tractor movement, GB shifting

ATTENTION: YOUR TRACTOR IS EQUIPPED WITH TURBOCHARGED ENGINE.
HIGH SPEED OF THE TURBOCHARGER REQUIRES GOOD LUBRICATION AT ENGINE
START. AFTER THE ENGINE START, WARM UP THE ENGINE TO ACHIEVE STABLE
RUNNING UNDER THE CRANKSHAFT SPEED OF 1000-1300 RPM (FOR 2-3 MIN), AND
THEN LET IT RUN AT HIGHER RPM, GRADUALLY INCREASING THE SPEED UP TO
1600 RPM (NOT MORE) UNTIL THE COOLANT TEMPERATURE REACHES 40°C.
TRACTOR OPERATION IS FORBIDDEN, IF THE ENGINE EMERGENCY OIL
PRESSURE LAMP IS ON WITH THE ENGINE RUNNING, STOP THE ENGINE IMMEDI-
ATELY!
Before starting the movement, define a necessary speed of tractor movement. The
speed diagrams of the tractor "BELARUS-922.6" with tires of basic configuration is given in
the instruction table attached to the cab right window and also in subsection 2.14 "GB range
and gear switching".
To put the tractor in motion, do the following:
- reduce engine speed;
- depress the clutch pedal;
- set a required GB range using the range shifting lever according to the range shift-
ing diagram, set a desired speed, for which move the speed and pass shifting lever from
neutral ("N") into any of positions according to the speed shifting diagram;
- if necessary, switch to the required increasing GB stage (if necessary switch the re-
verse gear to the required tractor travel(for tractors with a reverse gear)).
- disengage the parking break, slowly release the clutch pedal, increasing fuel feed at
the same time. The tractor will start moving.
