Regular Inspection
General Information
Engine oil lubricates, cools, seals, prevents corrosion, and cleans engines, enhancing engine
performance and extending the engine's lifetime. If the engine is continuously operated while
engine oil is insufficient the moving parts of the engine may get stuck, causing engine faults.
Engine oil should be checked with the oil level gauge and replenished if required. Oil level
should be checked while the engine is shut down. To check the oil level, shut down the engine
and wait for 5 ~ 10 minutes to allow the engine oil to flow back into the oil pan. The engine oil
level should indicate between the upper limit and the lower limit of the oil level gauge.
Engine oil should be periodically replaced based on the regular inspection table and the oil
filter and the cartridge should be replaced as the engine oil is replaced.
Engine Oil Standards
Use the specified engine oil suitable for the environment and conditions of the site where
the engine will be used.
Please use the engine oil which satisfies the following recommended specifications (See
Table 4-1).
