Information:
In order to avoid potential damage to your Cat machine and/or Cat engine, only purchase Cat fluids and Cat filters through your Cat dealer or Cat authorized outlets. For a list of authorized Cat parts outlets in your area, consult your Cat dealer.If you purchase what appear to be Cat fluids and/or Cat filters through other outlets/sources, you are at a very high risk of purchasing counterfeit ("look-alike") products.Counterfeit or "look-alike" products may visually appear the same as the original Cat product, but the product performance and internal quality will typically be very low.Counterfeit or "look-alike" products have a very high likelihood of causing and/or allowing engine and/or machine compartment damage.
Follow all industry standard safety practices when operating engines and/or machines and when performing all recommended and/or required maintenance.Note: Instructions for the installation of the filter are printed on the side of each Cat spin-on filter. For non-Cat filters, refer to the installation instructions that are provided by the supplier of the filter.
In order to meet expected fuel system component life, 4 micron(c) absolute or less secondary fuel filtration is required for all Cat diesel engines that are equipped with common-rail fuel systems. Also, 4 micron(c) absolute or less secondary fuel filtration is required for all Cat diesel engines that are equipped with unit injected fuel systems. For all other Cat diesel engines (mostly older engines with pump, line and nozzle type fuel systems), the use of 4 micron(c) absolute or less secondary fuel filtration is strongly recommended. Note that all current Cat diesel engines are factory equipped with Cat Advanced Efficiency 4 micron(c) absolute fuel filters.In order to obtain additional information on Cat designed and produced filtration products, refer to the "Reference Material" article, "Filters" and "Miscellaneous" topics in this Special Publication. Consult your Cat dealer for assistance with filtration recommendations for your Cat machine.
Caterpillar does not warrant the quality or performance of non-Caterpillar fluids and filters.
General Recommendations and Guidelines
Follow all applicable industry standards and all applicable governmental, environmental, and safety guidelines, practices, regulations, and mandates.Note: These general recommendations and guidelines concerning maintenance and care of fuel and fuel storage systems are not intended to be all inclusive. Discuss proper fuel safety and health, handling, and maintenance practices with your fuel supplier. Use of these general recommendations and guidelines does not lessen the engine owners and/or fuel supplier responsibility. All industry standard practices for fuel storage and for fuel handling must be followed.Note: Where recommendations for draining water and/or sediment and/or debris are stated, dispose of this waste according to all applicable regulations and mandates.Note: Cat filters are designed and built to provide optimal performance and protection of the fuel system components.
Discuss application-specific fuel concerns, needs, and requirements with a reputable fuel supplier.
Purchase fuel from a reputable supplier.
Use fuel that meets or exceeds Cat requirements for distillate diesel fuel. Refer to the "Cat Specification for Distillate Diesel Fuel for Nonroad Diesel Engines" table in this Special Publication, "Distillate Diesel Fuel" article.
Confirm with the filter manufacturer that the
