The instruments or gauges are essential for safety, maximum productivity and long service life
of the machine. Inspect the gauges and test any diagnostic lamps prior to start-up. During
operation observe the gauges and any lamps for proper functioning. Refer to Operating
Controls, for the normal readings.
Fuel Tank
CLEAN fuel in the fuel tanks is vitally important and every precaution should be taken to

non-metallic funnel.

clean distilled water.
