C4.4 (Mech) Industrial Engine Before Starting Engine Caterpillar


Before Starting Engine
`

Perform the required daily maintenance and other periodic maintenance before the engine is started. Inspect the engine compartment. This inspection can help prevent major repairs at a later date. Refer to the Operation and Maintenance Manual, "Maintenance Interval Schedule" for more information.

  • For the maximum service life of the engine, make a thorough inspection before the engine is started. Look for the following items: oil leaks, coolant leaks, loose bolts and trash buildup. Remove trash buildup and arrange for repairs, as needed.

  • Inspect the cooling system hoses for cracks and for loose clamps.

  • Inspect the alternator and accessory drive belts for cracks, breaks, and other damage.

  • Inspect the wiring for loose connections and for worn wires or frayed wires.

  • Check the fuel supply. Drain water from the water separator (if equipped). Open the fuel supply valve (if equipped).


NOTICE

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.

------ WARNING! ------

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.


  • Do not start the engine or move any of the controls if there is a "DO NOT OPERATE" warning tag or similar warning tag attached to the start switch or to the controls.

  • Ensure that the areas around the rotating parts are clear.

  • All of 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 of the shutoffs or alarm components (if equipped).

  • Check the engine lubrication oil level. Maintain the oil level between the "MIN" mark and the "MAX" 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.
