Note： Engine Development Dept.

①Since the durability of electric parts basically apply to R2 level of JIS D0203,please Manager
inform the customer not to clean with steam or high pressure water.
②Electric parts should not mounted on the engine directly (relay, timer etc.) must be
kept free from wet & high humidity and be kept with good air ventilation.
Regarding the vibration of the electrical components, these vibration level must be kept
less than 4G.
③Since there is the possibility of corrosion problem on engine cylinder liner or other Sec.Manager
parts,please do not sell and use the engine with EGR valve in other than emission
regulated area.(Emission regulated area means North America,Europe and Japan)

APPLICATION STANDARD
The engine operating environment and driven machine conditions must be studied carefully when selecting
an engine in order to make the most of the engine performance, extend the service life and improve the
machine capacity.
This manual describes the items that must be considered when selecting an engine and determining the
specifications to ensure that the engine is not used beyond its capacity.
