NOTICE
If the appropriate mixture of antifreeze is not used during freezing
temperatures, failure to drain the engine may cause costly engine
damage. Never use water only, as corrosion inhibitors are required in
engine coolant fluid.
CAUTION
!
No smoking, sparks, or open flame near fuel.
Check the fuel level and add fuel as necessary. Ultra-low sulfur diesel fuel (ULSD), with a
maximum sulfur content of 15 ppm is required. If ultra-low sulfur diesel is not used, the engine
could possibly not meet emissions regulations and the engine or aftertreatment system may
be damaged. Refer to the Engine Operator Manual for fuel specifications.
NOTICE
To minimize condensation (water) in the fuel tank, it is recommended to
fill the tank at the end of each day.
NOTE: Compressor will not allow engine starting if the fuel level is below
the minimum fuel shut off level.
WARNING
!
Compressor produces loud noise with doors open. Extended exposure to
loud noise can cause hearing loss. Wear hearing protection when doors
or valve(s) are open.
Close the doors to maintain a cooling air path and to avoid recirculation of hot air. This will
maximize the life of the engine and compressor and protect the hearing of surrounding
personnel.
Ensure no one is IN or ON the compressor.
Ensure that the location of the Emergency Stop Button (if equipped) is known and recognized
by its markings. Ensure that it is functioning correctly and that the method of operation is
known.
