Settings
1. To check or adjust the air pressure, screw or pull the protec-
tive cap off the valve and open the valve as appropriate.
2. Attach an air pressure gauge or an air pump with a pressure
indicator to the valve and read the pressure values. Ensure
that you are using the correct attachment for your type of
valve.
•
If the air pressure is too low, pump the tyres with an air
pump.
•
If the air pressure is too high, release some of the air.
• Select an air pressure within the upper and lower limits
given on the tyres and which is appropriate for your body
weight, the bike’s load and your riding habits.
3. Screw or push the protective cap back onto the valve after
adjusting the air pressure.
• Do not use excessive force in the process.
4. After adjusting the air pressure, check the lower knurled nut
is secure and tighten it if necessary (see Fig.
“Valve types”
).
•
Carefully tighten the knurled nut.
