D ANGER : The front axle suspension pressure lines between the central control block (ZSB) and the suspension cylinders, and are under 200 bar pressure, even when the engine is switched off and the suspension is lowered (= locked). I005112 Fig. 2. Cleaning, maintenance and repair work may only be carried out once the engine is switched off and secured to pre- vent it starting. In the event of leaks to the high-pressure fuel system, always remain out of range of any possible fuel spray to avoid serious injury.
Even when no leaks to the high-pressure fuel system can be detected, workshop personnel should avoid the imme- diate danger area and wear suitable protective clothing (such as protective goggles) when carrying out checks to the running engine and during the first test run. Safety measures: Prior to each repair and after releasing or opening in this area, the pressure must be released manually. N OTE : The "Lock suspension/lower suspension" command has no effect! Even externally energising the solenoid valves Y013 - Suspension load pressure/lowering solenoid valve and Y014 - Raise suspension solenoid valve is not effective!
(Hydraulically unlockable non-return valves are fitted, RVFH raise suspension non-return valve/RVFS lower suspension non-return valve). Before carrying out checks to the running engine, always perform a visual check of all high-pressure components. Suitable protective clothing (e.g. protective goggles) should be worn while doing this. Leaks indicate potential sources of danger for workshop personnel. Only start the engine once all safety guards have been attached and nobody is standing in the danger area. After switching off the engine, wait 30 seconds before carrying out any work on the fuel system. Do not loosen any injection lines for high-pressure fuel lines while the engine is running.
Never let the engine run in enclosed spaces with no exhaust gas suction system. Check: As the oil temperature rises, the emptying accumulator will make a flowing sound (barely audible in winter). the pressure accumulator on central control block ASP1 and Any damaged injection line or high-pressure line must be replaced. Injection lines and high-pressures lines must not be deformed. Smoking is forbidden while carrying out work to the fuel system. Do not work in the proximity of sparks or naked flames. Never disconnect an injector while the engine is running.
