MTU 12 V 4000 L63 Operating Instructions Manual page 14

• Pay special attention to the pressure level in the compressed air network and pressure vessel!
• Assemblies or plants to be connected must either be designed for this pressure, or, if the permitted
pressure for the connecting elements is lower than the pressure required, a pressure reducing valve
and safety valve (set to permitted pressure) must form an intermediate connection.
• Hose couplings and connections must be securely attached.
• Always wear protective goggles when blowing off tools or extracting chips.
• Provide the mouthpiece of the air nozzle with a protective disk (e.g. made of rubber).
• First shut off compressed air lines before compressed air equipment is disconnected from the supply
line, or before equipment or tool is to be replaced.
• Unauthorized use of compressed air, e.g. forcing flammable liquids (danger class AI, AII and B) out of
containers, results in a risk of explosion!
• Forcing compressed air into thin-walled containers (e.g. containers made of tin, plastic and glass) for
drying purposes or to check for leaks, results in a risk of bursting!
• Carry out the leak check as specified.
Painting
• When carrying out painting work outside the spray stands provided with fume extraction systems, en‐
sure that the area is well ventilated. Make sure that neighboring work areas are not impaired.
• No naked flames!
• No smoking!
• Observe all fire-prevention regulations!
• Always wear a mask providing protection against paint and solvent vapors!
Liquid nitrogen
• Store liquid nitrogen only in small quantities and always in specified containers without fixed covers.
• Avoid body contact (eyes, hands).
• Wear protective clothing, protective gloves, closed shoes and protective goggles / safety mask!
• Make sure that working area is well ventilated.
• Take great care not to subject containers, fittings and tools to impact or shock.
Acids/alkaline solutions
• When working with acids and alkalis, wear protective goggles or face mask, gloves and protective
clothing.
• If acids or alkalis are spilled onto clothing, remove the affected clothing immediately!
• Rinse injured parts of the body thoroughly with clean water!
• Rinse eyes immediately with eyedrops or clean mains water!
