To replace the lubricating oil of the lifting mechanism, first run the crane mechanism for 10-15 minutes, open the oil drain plug at the bottom of the winch, discharge the residual oil, screw on the oil drain plug, and fill in new oil from the top filling port until New oil flows out from the oil level observation hole on the side.

When the ambient temperature is above -15°, add L-CKD220 industrial gear oil in general areas, and when the ambient temperature is 15°~35°, add L-CKT220 industrial gear oil in a low temperature environment.

Gear oil that does not meet the standard will reduce the service life of the slewing mechanism and the lifting mechanism.
