LEVER 7P7382 - Caterpillar

All valves in the fuel return line must be open before and during engine operation to help prevent high fuel pressure. High fuel pressure may cause filter housing failure or other damage.
If the engine has not been started for several weeks, fuel may have drained from the fuel system. Air may have entered the filter housing. Also, when fuel filters have been changed, some air pockets will be trapped in the engine. In these instances, prime the fuel system. Refer to the Operation and Maintenance Manual, "Fuel System - Prime" for more information on priming the fuel system.
Engine exhaust contains products of combustion which may be harmful to your health. Always start and operate the engine in a well ventilated area and, if in an enclosed area, vent the exhaust to the outside.
If a "DO NOT OPERATE" warning tag or similar warning tag is attached to the start switch or controls, do not start the engine or move any controls.
Ensure that the areas around the rotating parts are clear.
All the guards must be put in place. Check for damaged guards or for missing guards. Repair any damaged guards. Replace damaged guards and/or missing guards.
Disconnect any battery chargers that are not protected against the high current drain that is created when the electric starting motor (if equipped) is engaged. Check electrical cables and check the battery for poor connections and for corrosion.
Reset all the shutoffs or alarm components.
Check the engine lubrication oil level. Maintain the oil level between the "ADD" mark and the "FULL" mark on the oil level gauge.
Check the coolant level. Observe the coolant level in the coolant recovery tank (if equipped). Maintain the coolant level to the "FULL" mark on the coolant recovery tank.
If the engine is not equipped with a coolant recovery tank, maintain the coolant level within 13 mm (0.5 inch) of the bottom of the filler pipe. If the engine is equipped with a sight glass, maintain the coolant level in the sight glass.
Observe the air cleaner service indicator (if equipped). Service the air cleaner when the yellow diaphragm enters the red zone, or when the red piston locks in the visible position.
Ensure that any driven equipment has been disengaged. Minimize electrical loads or remove any electrical loads.SCR System Inspection
SCR System
Ensure that area around SCR system is clear of flammable materials.
Inspect access panels.
Inspect injector.
Inspect bulkhead fittings.
Ensure that urea and air lines are connected.
Inspect sensors.
Inspect wiring harness.Dosing Control Cabinet
Ensure that filter screens are in place.
Ensure that drains are closed.
Ensure that all lines are connected.
Check for leaking fluids. Ensure all fluids that have leaked are cleaned up and properly disposed of.
Check the A/C power supply.Powering Up the Dosing Cabinet
Turn on both breakers that are on the dosing cabinet. The control program should automatically boot up on the Touch-Panel Screen.Once properly commissioned, the dosing cabinet is designed to operate automatically without operator intervention. The controller software measures operating conditions and adjusts the amount of DEF injection to achieve the desired reductions.
