Question you may concern
How to check the hydraulic oil level?
Park the excavator on a flat ground, turn off the engine and wait for a while, then check the hydraulic oil level through the oil level gauge of the hydraulic oil tank.
What to do if the hydraulic pump makes abnormal noises?
Abnormal noises from the hydraulic pump may be due to air entering the hydraulic system, contaminated hydraulic oil, or internal wear of the hydraulic pump. Check the condition of the hydraulic oil, inspect the suction line for leaks, and replace the hydraulic pump or related components if necessary.
What causes the efficiency of hydraulic pumps to decrease?
The reasons for the decrease in efficiency include wear of internal components, filter blockage, hydraulic oil contamination and insufficient system pressure.
What causes hydraulic pump cavitation?
Possible low hydraulic oil level, high oil viscosity, or restricted fluid flow.
Solution: Refill hydraulic oil, use correct viscosity oil, check and clear restricted areas.
