COOLER GP-ENGINE OIL 7N8721 - Caterpillar

Personal injury can result from air pressure.Personal injury can result without following proper procedure. When using pressure air, wear a protective face shield and protective clothing.Maximum air pressure at the nozzle must be less than 205 kPa (30 psi) for cleaning purposes.
Personal injury can result when using cleaner solvents.To help prevent personal injury, follow the instructions and warnings on the cleaner solvent container before using.
Personal injury or death can result from a fire.Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire.Clean up all leaked or spilled fuel. Do not smoke while working on the fuel system.Turn the disconnect switch OFF or disconnect the battery when changing fuel filters.
Do not pre-fill the fuel filter with fuel before you install the fuel filter. Contaminated fuel WILL DAMAGE the fuel system components.
Caterpillar STRONGLY recommends the use of high efficiency fuel filters. High efficiency fuel filters are designed in order to better protect diesel engines that have higher injection pressures and closer tolerances. Use of fuel filters that are NOT high efficiency fuel filters will result in shortened fuel system component life. Caterpillar high efficiency fuel filters are the preferred filters for Caterpillar engines.
In order to keep the engine in optimum condition, it is important to keep the fuel free from contamination. As fuel system contamination usually occurs during refueling, the following points should be observed:
Only use clean fuel of the correct grade from a reliable source.
Do not refuel from contaminated containers or containers that are not suitable for fuel storage.
Do not use contaminated equipment.
Regularly clean the outside of the fuel filler cap and the area around the fuel filler cap.
Only use Caterpillar approved fuel filters. The use of Caterpillar filters is essential in order to protect the fuel system.
Do not service the fuel filters ahead of the suggested maintenance interval, unless you are instructed by the monitoring system. This will increase the risk of contamination in the fuel system.Note: If equipped, the service indicator for “Water in Fuel” will be illuminated if the sediment bowl needs to be emptied.Note: The service indicator on the dash will be illuminated if the fuel filters need to be changed. All machines have a sensor on the second filter in order to detect plugging. Certain machines have an additional sensor on the primary filter in order to detect plugging. Both sensors will illuminate the service indicator on the dash. If the service indicator is active, change all three fuel filters.Note: In order to reduce the risk of contamination in the system, do not remove the fuel filters simultaneously. Perform these operations separately.Note: After the engine has stopped, you must wait for 60 seconds in order to allow the fuel pressure to be purged from the high pressure fuel lines before any service or repair is performed on the engine fuel lines.
Open the engine access door on the left side of the machine. The fuel filter element is located toward the front of the engine.
Turn the fuel supply valve (if equipped)
