PERIODIC MAINTENANCE
• Always be environmentally
responsible.
• Follow the guidelines of the EPA or other
governmental agencies for the proper disposal of
hazardous materials such as engine oil, diesel
fuel and engine coolant. Consult the local
authorities or reclamation facility.
• Never dispose of hazardous materials
irresponsibly by dumping them into a sewer, on
the ground, or into ground water or waterways.
• Failure to follow these procedures may seriously
harm the environment.
Drain the water separator whenever there are
contaminants, such as water, collected in the
bottom of the cup. Never wait until the scheduled
periodic maintenance if contaminants are
discovered.
The separator cup is made from semi-transparent
material. In the cup is a red-colored float ring. The
float ring will rise to the surface of the water to show
how much needs to be drained. Also, some optional
water separators are equipped with a sensor to
detect the amount of contaminants. This sensor
sends a signal to an indicator to alert the operator.
