Working Clothes and Protective Equipment
• Always wear protective shoes when working on plant.
• Select protective goggles according to the work to be carried out. Always wear protective goggles when working
with mallets, cutting tools, drift punches or similar.
• Work clothing must be tight-fitting so that it does not catch on rotating or projecting parts. Do not wear jewellery
(rings, chains, etc.).
Welding Operations
• Never use the engine as a ground terminal! (This prevents the welding current from passing through the engine,
resulting in burnt or scorched points on the bearings, friction surfaces and tooth flanks which can lead to bearing
scorching and/or material damage).
• Welding on the engine or engine-mounted components is forbidden.
• Never lay the welding cable over or near the cable harnesses of the DB/MTU plants. (The welding current could
be induced in the cable harnesses which could possibly damage the electrical plant).
• The ground terminal of the welding unit must be connected to the welding point at a distance of no greater then
60 cm.
• If work must be carried out on components, (e.g. exhaust pipe), then these components must be removed from
the engine beforehand.
• With the DB/MTU electronics system, it is not necessary to remove the connector and connections to carry out
welding if the power supply master switch has been switched from "On" to "Off", and the cables have been
disconnected from the negative and positive battery terminals.
• During welding operations, always wear welding gloves, headgear, goggles, protective apron and other suitable
protective clothing.
Transport
• Lift the engine using only the lifting eyes provided.
• Use only the transport and lifting equipment approved by DB or MTU.
• Transport the engine only in the installation position.
Engine Operation
• Wear ear protectors in the engine room when the engine is running.
• Ensure the engine room is well ventilated.
• Leaked or spilt engine oil and coolant must be cleaned up immediately or absorbed with appropriate bonding
agents to avoid injuries caused by falling.
• Exhaust gases from combustion engines are poisonous. They can be injurious to health if inhaled. The exhaust
system must be leak-tight and discharge the gases to atmosphere.
• Do not touch battery terminals, generator terminals or cables during engine operation. Inadequate protection of
the electrical components can lead to electric shocks and serious injuries.
• If engine is running, never release coolant, oil, fuel, compressed air or hydraulic lines.
Maintenance and Repair
• Compliance with the maintenance and repair instructions is a major safety factor.
• Unless expressly permitted, no maintenance or repair work is to be carried with the engine running. The engine
must be secured against inadvertent starting, the battery disconnected and the "Do not operate" sign put up in
the operating area or attached to the control equipment. Persons not involved must be kept 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 authorised and qualified personnel.
