Tire Inflation - Belarus 922.6 Operator's Manual

Pressure shall be set in "cold" tires.
Acceptable limit deviations in the tires are (± 10 kPa) acc. to pressure gauge indications.
Performing operations which require large pulling force on the hook, set the pressure as for
the speed of 30 km/h. When performing transport operations on roads with hard surface, increase
pressure by 30 kPa, but no more than
tires 360/70R24).
If transport operations increase 60%, the warranty lifetime of the tire within the limits of war-
ranty storage time decrease by 30%.
Tractor operation with twinned tires is allowed only at the speed of 20 km/h.
Maximum permissible loads are given for single tires. Total permissible load G
at twinning makes 1.7G, where G is permissible load on single tire according to table 3.2.3.
When twinning tires, make sure the pressure in outer tires is 1,2 – 1,25 times lower than the
pressure in inner tires.
Permissible maximum pressure deviations in tires are (±10 kPa) according to manometer indica-
tion.

3.2.8.2 Tire inflation

Inflate tires through an air bleed valve of pressure regulator 1 (Figure 3.2.2), for which do the
following:
- let the air out of balloon 3 of the pneumatic system through a condensate removing valve;
- unscrew winged nut 2 of the air bleed valve cap;
- connect a pipe for tire inflation to the air bleed valve cap and to a tire valve;
- start the engine and inflate the tire to reach the required pressure, controlling it with a pres-
sure gage МД-214 GOST 9921-81 (or with a pressure gage having identical metrological character-
istics);
- disconnect the pipe from the tire valve and from the air bleed valve cap;
- screw the winged nut back on the air bleed valve cap.
ATTENTION: AS PRESSURE IN THE BALLON GOES UP TO 0.77 MPA, THE COMPRES-
SOR IS SWITCHED TO IDLE RUNNING BY THE PRESSURE REGULATOR AND TIRE INFLA-
TION STOPS AUTOMATICALLY. FOR THIS REASON CHECK THE PRESSURE OVER THE IN-
DICATOR ON THE DASHBOARD FROM TIME TO TIME AND, IF NECESSARY, REDUCE IT
THROUGH THE CONDENSATE REMOVING VALVE!
1 – pressure regulator; 2 – winged nut; 3 – balloon of the pneumatic system.
The tires of the tractors with no trailer brake drive are inflated through the tire inflating valve,
which is located on the pneumatic compressor.
Inflate the tire through the tire inflating valve as follows:
- unscrew the winged nut and remove cap 2 (see Figure 3.2.3) of union 3;
- connect the tire inflation hose to air bleeding union 3 and to the tire valve;
- activate AIR COMPRESSOR 1 and inflate the tire up to the required pressure. Use a tire
pressure gauge to control the pressure;
- disconnect the hose from the tire valve and the air bleeding union;
- turn off AIR COMPRESSOR 1 and tighten the winged nut or mount cap 2 on union 3 of tire
inflation valve 4.
