Air pressure system

You can get pressurised air (8 bar) for external purposes, for example for filling
tyres, from the air pressure system (extra equipment).
IMPORTANT: Do not weld or drill the pressure container.
The pressure regulator is provided with a built-in pressure relief valve which
operates if the pressure rises to 12-14 bar. For example, a broken pressure
regulator valve or a frozen or blocked filter can cause this situation.
