6.1.3 Tyre inflating connection
Location
Make sure that the supply pressure on
the pressure gauges is not at maximum,
but at about 8 to 9 bar.
While inflating the tyres, keep the pres-
sure on this value by having the air
compressor running.
See chapter 'Technical data and identifi-
cation' for the correct tyre pressures.
Refit the rubber cap of the tyre inflat-
ing connection after the tyre has been
inflated.
NOTE:
The tyre inflating connections can also be used as an external inflating
connection to fill the air pressure system with air from outside. When
doing this, check that the system pressure is correct using the air pres-
sure gauge.
