2. Regulations for the prevention of engine damage and premature wear
D The engine must be cleaned thoroughly prior to repair. Ensure that during repair work no dirt,
sand or foreign bodies enter the engine.
D If engine operation is disrupted, immediately determine the cause and have it remedied to prevent addi-
tional damage.
D In every case, use only original MAN spare parts. The installation of parts that are "just as good" but do
not originate from MAN can under certain circumstances cause severe damage − for which the work-
shop performing the repair must bear responsibility.
D Never allow the engine to run dry, i.e. without lubricant or coolant.
Appropriate notices must be attached to engines that are not ready for operation.
D Only use lubricants, fluids and fuel approved by MAN (gas, engine oil, antifreeze and corrosion protec-
tion agents). Pay attention to cleanliness.
D Do not fill engine oil beyond the max. notch on the dipstick. Do not exceed the maximum per-
missible tilt of the engine.
Serious damage to the engine may result if these instructions are not adhered to.
D Control and monitoring devices (charge control, oil pressure, coolant temperature) must be in perfect
working order.
3. Safety instructions for handling the ignition system
D When the engine is in operation, the following parts of the ignition system must not be
touched or disconnected under any circumstances:
− Ignition coils and caps
− Cables of the high-voltage circuit
− Cables of the low-voltage circuit
− Plugs of the output and input wiring harness
D For all work related to set-up, operation, conversion, customisation, maintenance and
repairs, the power must be disconnected from the ignition system and secured against
inadvertent reactivation.
