Whether in dusty environments or under heavy-duty operational demands, the kit provides reliable protection for the machinery, ensuring stable and consistent performance.

V. Selection and Maintenance Guide: Making Protection More Precise

(1) Scientific Replacement Cycle

• Oil filter element 53C0053 ): Under normal operating conditions, replace according to the standard cycle; no adjustment of the replacement frequency is needed for special conditions such as mining or dusty environments.
• Diesel filter element assembly 53C0945+40C7018+SP133752 ): Under normal operating conditions, replace according to the standard cycle; however, in special conditions such as mining or dusty environments, appropriately shorten the replacement interval.
• Air filter element 40C2952 ): Under normal operating conditions, the replacement interval can be extended; however, in special conditions such as mining sites or dusty environments, the interval should be appropriately shortened.
• Hydraulic filter element 53C0658+53C0210P02 ): Under normal operating conditions, replace according to the standard cycle; no adjustment is needed under special conditions.
