◆ Fire and explosion
(1) Fuel and lubricating oil
All the types of fuel, most types of lubricating oil and many chemical products are flammable. Please
read and observe instructions marked on the packages. All the operations related to the fuel system
must be performed after the engine is cooled because fuel splashed on hot surfaces or electrical parts
may cause fire. All the rags immersed in fuel and lubricating oil as well as other flammable materials
must be safely stored in a fire-proofing place. Under certain conditions, rags immersed in the
lubricating oil may be ignited spontaneously. Smoking is strictly forbidden while filling fuel or
lubricating oil, or near the fuel station and inside the engine room.
(2) Spraying liquid for engine start
Don’t start the engine equipped with air preheat device (glow plug/starting heater) using spraying
liquids or equivalents. Otherwise explosion may occur inside the air intake manifold threatening
personal safety.
◆ Hot surface and high-temperature liquid
There are dangers of scalding for people operating with high-temperature engines. Pay special
attention to hot surfaces, such as exhaust pipe, turbocharger, oil pan, supercharged air pipe, starting
heater, high-temperature cooling liquids, and high-temperature lubricating oil inside tubes.
◆ Chemical products
Most types of chemical products, such as anti-freezing liquids, anti-rust agents, oil seal greases and
degreaser agents are harmful for people’s health. Please read and observe instructions marked on the
packages. Some chemical products, for example, oil seal greases are flammable and harmful for human
body once these substances are inhaled by people. Place chemical products and other hazardous
substances out of reach of children. Please dispose used and residual chemical products in accordance
with regulations for the benefits of environment protection.
◆ Cooling system
Don’t open the cap of cooling liquid for high-temperature engines to avoid any scalding as a result of
spraying of steam or high-temperature cooling liquids. If you inevitably open the filling cap or switch
of cooling liquid or you must remove the cooling liquid tubes, please unscrew the cap slowly and
carefully to discharge the pressure before fully opening the filling cap. Pay attention that high-temperature
