Action
Check readings of operating data (speed, temperature, pressures).
Check for presence of emissions label and check readability and content (on-
ly for EPA area) (→ Page 185).
Engine oil level – Check (→ Page 285)
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.
Check fuel prefilter service indicator (if applicable) (→ Page 268).
Drain water and contaminants from fuel prefilter (if applicable) (→ Page 263),
(→ Page 265).
Check exhaust color (→ Page 194).
Check condensate drain(s) for water discharge and obstruction
(→ Page 276).
Check signal ring position of contamination indicator (→ Page 280).
Replace air filter (→ Page 277), if the signal ring is completely visible in the
service indicator window.
Check relief bore (→ Page 300).
