Properly inflated tyres save you money. Maintaining correct tyre pressures reduces fuel consumption and maximises tyre life.
To read a tyre pressure, press the POWER button to turn the unit ON, then press the POWER button until the correct scale appears either psi, bar, kpa or Kg/cm2. Push the gauge onto the valve firmly and hold it in place for approximately 2-3 seconds then remove and read the tyre pressure. The tyre pressure will display for 10 seconds and then zero itself. The unit will power OFF automatically after 30 seconds.
