  IMPORTANT SAFETY PRECAUTIONS

General Safety Precautions

•  Read all instructions before use to avoid injury .
•  To avoid serious injury or death, follow the safety information in this document .
•  Keep this manual . If you need to replace the manual, call customer service at 800-328-2611  

or visit www .davco .com/documents for a replacement .

•  Read all product safety labels .
•  Refer to appropriate regulations for environmental and workplace safety rules .

WARNING: To prevent personal injury

• 

Scalding hazard:

 When diesel fuel is circulated through an operating engine, it can become very hot . Do not al-

low fuel to come in contact with eyes or unprotected skin . Allow the engine and fuel to cool to ambient tempera-
ture before replacing the fuel filter or performing service operations which could result in spillage of fuel from the 
fuel system .

• 

Fire Prevention: 

Heated fuel can form combustible vapor mixtures in the area around the fuel source . To elimi-

nate the potential for fire, keep open flames, sparks or other potential ignition sources away from the work area . 
Do not smoke during filter replacement or service operations . 

• 

Inhalation Precaution:

 Always perform engine or vehicle fuel system maintenance in a well ventilated area that is 

kept free of bystanders .

•  The ignition key must be in the

 off 

position, unless otherwise directed . To avoid unintentional engine startup, use 

a lockout key and/or signage to alert personnel that work is being performed .

Government Regulations

•  Engine fluids (oil, fuel, and coolant) may be a hazard to human health and the environment . Handle all fluids and 

other contaminated materials (such as filters and rags) in accordance with applicable regulations . Recycle or dis-
pose of engine fluids, filters, and other contaminated materials according to applicable regulations .
