Operation and Maintenance Manual SC9DF Electronically Controlled Diesel Engine for Agricultural Equipment

●When working on the engine, remain alert at all times. Never work on the engine when physically or mentally
fatigued.
●Do not smoke when working on the engine.
●Smoking is not allowed during fuel refilling, otherwise, fuel steam can cause fire easily.
●Smoking is not allowed when checking battery electrolyte level because electrolyte releases flammable gases.
●Do not wear a loose garment or any jewelry when working around the engine or its driven equipment. If necessary,
wear safety goggles, work clothes, safety helmet or other protective items.
●Do not remove guards and protective devices with which the engine is equipped for its exhaust system parts and
exposed rotating parts when required, or personal injure can be likely triggered. To prevent personal injury, all the
exposed rotating parts such as fan, and exhaust parts like exhaust manifold, exhaust tailpipe, turbine, muffler should
be provided by OEM with secured guards and protective devices. Never operate the engine without guards and
protective devices.
●Make regular cleaning of the engine during harvest season to clean away inflammable matter such as crop stalks
that enter through the clearance of the guards and cover the surface of the engine to avoid high coolant temperature
or fire.
●Do not put flammable stuff like fuel, lubricating oil, coolant, or danger stuff like explosive around the engine. They
may cause fire or explosion.
●Wipe up any fuel, oil or coolant spills. They may cause fire when being lighted. Put rags with fuel, oil or coolant into a
fire-protection container, and do not leave it on the engine.
●Remove dust, mud or other odds and ends on the engine. They can be a cause of fire or engine overheating.
●Before starting the engine, make sure there are no persons around, nor tools or other things on the engine. Do not
start the engine when a tag of Do Not Start is on the starting switch.
●When fuel, oil, or exhaust gas leak is found, take measures to eliminate the leakage source immediately. Splashed
fuel or oil on high temperature parts or exhaust gas contacting flammable stuff can cause fire, personal injure or
engine damage.
●Do not check fuel, oil and coolant leaks with hand. High pressure and high temperature fuel, oil or coolant can cause
personal injure. Be very careful when checking fuel leak, because high pressure fuel can inject into skin and cause
personal injure or even death. Use a thick plate to check for fuel leak and avoid contacting injected fuel when finding
fuel leak.
●Use an explosion-proof light to check fuel, oil, coolant or electrolyte if light is needed to prevent fire explosion.
●Do not smoke, and do not use fire when handling or working near fuel system components, for fuel steam may be
lighted and cause damage to components or personal injure.
●Do not make any maintenance to fuel system parts when the engine is in operation.
●Fuel flows from the injection pump to the injectors through the high pressure fuel pipes under very high pressure. Do
not loosen the high pressure fuel pipes when the engine is in operation. This will result in serious scald.
●The common rail fuel system generates high electric voltage during engine operation. Do not touch the injector
solenoid wires or solenoid parts. This will result in serious electric shock.
●If the engine will not be used for a long time or for repair, always disconnect the battery cables or the air line of an air
