PERIODIC MAINTENANCE
Clean Fuel Filter / Water Separator
DANGER
FIRE AND EXPLOSION HAZARD!
• Diesel fuel is flammable and
explosive under certain
conditions.
• NEVER use diesel fuel as a cleaning agent.
• When you remove any fuel system component
to perform maintenance (such as changing
the fuel filter) place an approved container
under the opening to catch the fuel.
• NEVER use a shop rag to catch the fuel.
Vapors from the rag are flammable and
explosive.
• Wipe up any spills immediately.
• Wear eye protection. The fuel system is under
pressure and fuel could spray out when you
remove any fuel system component.
• Failure to comply will result in death or
serious injury.
NOTICE
• 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.
