Removing the thermostat when the coolant temperature is (too) high serves no useful purpose and is strongly advised against, since this will only cause the engine temperature to rise to an even higher level. If the pressure in the air reservoirs drops rapidly with the engine switched off, this indicates a leak. Since this affects the safety of the brake system, the leak must be traced and repaired as quickly as possible. The vehicle is equipped with a 24-Volt electrical system. When replacing or fitting electrical or electronic components, always verify that they are suitable for this system voltage.
Always disconnect the battery earth lead before carrying out repairs or service on the electrical system. Never place tools on a battery. This may cause a short circuit and may even cause the battery to explode. The turbocharger is a precision component. You should therefore immediately report any abnormal noise that seems to be coming from this component. Never disconnect the battery leads while the engine is running! Always charge batteries in a properly ventilated area and avoid sparking and naked flames due to the danger of explosion. Warnings and Safety Regulations System voltage Air leakage Batteries } } 22
