Maintenance and repair
Compliance with maintenance and repair specifications is an important safety factor.
Unless expressly permitted, no maintenance or repair work is to be carried out with the engine running. Ensure the
engine cannot be started unintentionally. On engines equipped with electrical starter, disconnect the starter battery.
On engines equipped with air starter, close the shut-off valve of the compressed-air system and vent the
compressed-air line. Fit the warning label "Do not operate" either in the operator's room or on the control
equipment! Persons not involved must keep clear.
Never attempt to rectify faults or carry out repairs if you do not have the necessary experience or special tools
required. Maintenance and repair work must only be carried out by authorized, qualified personnel.
Use only proper, calibrated tools.
Do not work on engines or components which are only held by lifting equipment or crane. Always support these
components in accordance with regulations on suitable frames or stands before beginning any maintenance or
repair work.
Before barring the engine, make sure that nobody is standing in the danger zone. After working on the engine,
check that all guards have been reinstalled and that all tools and loose components have been removed from the
engine.
Fluids emerging under high pressure can penetrate clothing and skin and may cause serious injury. Before starting
work, relieve pressure in systems and H.P. lines which are to be opened.
Never bend a fuel line and do not install bent lines. Keep fuel injection lines and connections clean. Always seal
connections with caps or covers if a line is removed or opened.
During maintenance and repair work, take care not to damage the fuel lines. To tighten the connections when
installing the lines, use the correct tightening torque and ensure that all retainers and dampers are installed
correctly.
Ensure that all fuel injection lines and pressurized oil lines have sufficient distance to other components to avoid
contact with them. Do not place fuel or oil lines near hot components, except when necessary for design reasons
during installation.
Elastomers (e.g. "Viton" sealing rings) are stable under normal operating conditions. When subjected to fire or
temperatures above 300 °C the material degenerates, giving off hydrogen fluoride gas. The resulting acid leads to
serious burning if it contacts the skin. Do not touch elastomeric seals if they have carbonized or resinous
appearance. Wear protective gloves!
Take care with hot fluids in lines, pipes and chambers
Risk of injury!
Note cooling period for components which are heated for installation or removal Risk of injury!
Do not touch hot parts of the compressor and the exhaust system Risk of injury!
Take special care when removing ventilation or plugs from engine. In order to avoid discharge of highly pressurized
liquids, hold a cloth over the screw or plug. It is even more dangerous if the engine has recently been shut down,
as the liquids can still be hot.
Take special care when draining hot fluids. Risk of injury!
When draining, collect fluids in a suitable container, mop up any spilt fluids or wipe or soak them with a suitable
bonding agent.
When changing the engine oil or working on the fuel system, ensure that the engine room is adequately ventilated.
