5.7 Operational monitoring
DANGER
Components are moving or rotating.
Risk of crushing, danger of parts of the body being caught or pulled in!
• Operate the engine at low load only. Keep clear of the danger zone of the engine.
WARNING
High level of engine noise when the engine is running.
Risk of damage to hearing!
• Wear suitable hearing protection.
Operational monitoring
Item Action
Control and display panels Check readings of operating data (speed, temperature, pressures).
Plate Check for presence of emissions label and check readability and content (on-
ly for EPA area) (→ Page 142).
Engine oil Engine oil level – Check (→ Page 237)
Engine under load
Engine at nominal speed
Check engine/plant and piping for leaks, repair leaky pipes with the engine
stopped (exhaust lines and turbocharger turbine housings may be red-hot. If
the maximum exhaust temperatures are not exceeded, no restrictions in en-
gine operation are required).
Check for abnormal running noises and vibration.
Fuel prefilter Check fuel prefilter service indicator (if applicable) (→ Page 220).
Drain water and contaminants from fuel prefilter (if applicable) (→ Page 215),
(→ Page 217).
Exhaust system Check exhaust color (→ Page 151).
Intercooler Check condensate drain(s) for water discharge and obstruction
(→ Page 228).
Air filter Check signal ring position of contamination indicator (→ Page 232).
Replace air filter (→ Page 230), if the signal ring is completely visible in the
service indicator window.
Engine coolant pump Check relief bore (→ Page 250).
Charge-air coolant pump Check relief bore (→ Page 273).
Compressed-air system (if
applicable)
Check operating pressure on pressure gauge;
Always fill compressed-air tank to max. pressure;
Drain condensate from compressed-air tank, pressure drop must not exceed
1 bar.
