Unusual Engine Noise
During daily maintenance checks, listen for any unusual engine
noise that can indicate that service is required.

Air Tanks and Reservoirs

Drain
If automatic purging or spitter valves are used, confirm the
valves are operating correctly. If a manual drain valve is used on
the wet tank, open the draincock on the wet tank to drain any
moisture accumulated in the air system.
If oil is present, the air compressor system must be checked.
Contact your Cummins Authorized Repair Location.
