You must read and understand the warnings and instructions contained in the Safety section of this manual before performing any operation or maintenance procedures.Walk-Around Inspection
To avoid personal injury due to unexpected start, attach a DO NOT OPERATE or similar warning tag to start switch or controls before performing maintenance or repairing the engine. When appropriate, attach tags at the engine and pilot position, and disconnect starting controls.DO NOT ALLOW UNAUTHORIZED PERSONNEL ON OR AROUND THE ENGINE WHEN IT IS BEING SERVICED.
Inspect Engine for Leaks and Loose Connections
A walk-around inspection is recommended to ensure the installation is clean and leaks are kept to a minimum. This should only take a few minutes and by taking the time to make these checks, costly repairs and accidents can be avoided and the equipment will be ready to run should the need arise.For maximum service life of your engine(s), make a thorough inspection before starting the engine. Look for such items as oil or coolant leaks, loose bolts, worn belts, loose connections and trash build-up. Remove trash build-up and have repairs made as needed.
Accumulated grease and oil on an engine and/or platform (walkway) is a fire hazard. Remove this debris with steam cleaning or high pressure water, Every 1000 Service Hour interval or each time any significant quantity of fluid is spilled on an engine and/or platform.
Check the fluid levels more frequently than the recommended maintenance intervals and continue to monitor fluid levels until any leak is found and fixed. If leaking is observed, find the source and correct the leak. If leaking is suspected, check the fluid levels more frequently than the recommended intervals.* Wipe all fittings, caps and plugs before performing maintenance to reduce the chance of system contamination.* Check the engine, cooling system, aftercooler and generator (if equipped) for dirt and debris. Inspect the radiator (if equipped) for leaks and trash build-up.* All guards must be in place. Repair or replace missing or damaged guards.Cooling System
Inspect:* Cooling system lines and elbows for cracks and loose clamps. Check the condition of all pipes and fittings.* Condition of all belts for cracks, breaks or other damage. Replace if necessary.Belts for multiple groove pulleys must be replaced as matched sets. If only one belt of a two or three belt set is replaced, it will carry more of a load than the belts not replaced since the older belts are stretched. The additional load on the new belt could cause it to break.* Water pump(s) for coolant leaks. The water pump seal is lubricated by coolant in the cooling system. It is normal for a small amount of leakage to occur as the engine cools down and parts contract. If leaks are found, check the coolant level frequently and continue to monitor the level until the water pump is repaired. Excessive coolant leakage may indicate the need to replace the water pump seal.For removal and installation of water pump(s) and/or seals, see the Service Manual for this engine or consult your
