Tires inflation
Inflate the tires using an air bleed valve of a pressure
regulator (1) in the following order:
• bleed air from a balloon (3) of the pneumatic system
through a valve of condensate ejection valve;
• unscrew a butterfly-nut (2) of an air bleed valve con-
necting pipe;
• connect a tire inflation hose to the air bleed connecting
pipe and a tire’s valve;
• switch a compressor on and inflate a tire up to a
required pressure level, controlling it by a tire manometer;
IMPORTANT! If pressure in a balloon exceeds 7,7 kgf/cm
2
, the compressor is switched
over to idling by a pressure regulator and tires inflation stops automatically. Thus, control a
pressure level by an indicator on the dashboard and decrease pressure through a conden-
sate ejection valve if necessary.
• disconnect the pump from the tire’s valve and the air bleed valve connecting pipe;
•
switch a compressor off and screw a butterfly-nut on the air bleed valve connecting
pipe;
