2. Lubrication system

Before starting a new machine, oil should be added through the oil filling port. When refueling, the engine should be placed in a horizontal position and attention should be paid to observing the oil

Changes in position. After adding oil, wait for a while before checking the oil level on the dipstick, which is the oil level that can be seen when all the oil flows into the oil pan

Bit is the correct value. Each oil filter should be filled with clean engine oil before it can be installed on the engine.

When choosing engine oil, it is important to choose the appropriate viscosity and comply with the American Petroleum Institute (AH) level performance rating.

CUM engines require the use of multi viscosity engine oil because multi viscosity engine oil is suitable for the operating temperature range

Wider and with a consumption rate about 30% lower than single viscosity engine oil. The performance level of engine oil represents the level of engine oil additives, which is crucial for

For heavy-duty engines, the main protective agents are the additives in the engine oil, which will gradually increase over time

CUM recommends using engine oil that meets the following standards: if the ambient temperature is above -5 ℃, use 15W

-40CF4, CG4, CF4/SG, or CG4/SH grade engine oil; When the ambient temperature is below -5 ℃, use 10W

-30CF4, CG4, CF4/SG, or CG4/SH grade engine oil. B and C series engines must use CF4/SG or

CG4/SH grade engine oil.

C-U-M recommends using engine oil, which has a viscosity index of 15W-40

The performance level is CG4/SH, and the formulation of the applicable agent is completely based on the unique performance characteristics of CUM engines

To effectively extend the oil change cycle of the engine and reduce the oil consumption rate.

Gradually depleting, only by selecting a sufficient level of oil can the engine be reliably protected throughout the entire oil change cycle
