Be responsible to the environment.
Follow these procedures for hazardous waste
disposal. Failure to follow these procedures may
seriously harm the environment.
• Follow the guidelines of the EPA or other
governmental agency 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.
NEVER wait until the scheduled periodic
maintenance if the fuel filter indicator comes on.
The fuel filter / water separator contains a sensor to
detect the amount of water and contaminants. This
sensor sends a signal to an indicator to alert the
operator.
Drain the fuel filter / water separator as follows:

bottom of the fuel filter / water separator. Drain
any water collected inside.
