For a full hydraulic excavator, it can be said that the hydraulic system is like the blood circulation system of the human body throughout the excavator. It includes a hydraulic oil tank, the main pump, a multi-way valve, various lines, and a cylinder that performs various actions. Motors and other hydraulic components are precision-machined. They have high requirements for the maintenance of the hydraulic system. Improper maintenance or failure to maintain will cause failures, cause machine shutdown, and bring you loss.

(1) Change the hydraulic oil and filter regularly

A good hydraulic oil contains a variety of additives that prevent the oil from spoiling.

However, these additives lose their effectiveness over time. Therefore, the oil should be changed regularly to ensure that the additives work.

The filter can only absorb a limited number of dirt particles and other impurities from the oil.

For replacing the hydraulic tank oil return filter every 1000 working hours, and clean the hydraulic oil tank suction filter when replacing the hydraulic oil in order to keep the system clean.

When replacing the hydraulic oil filter, please check whether there are metal particles or debris on the bottom of the filter; if copper or iron debris indicates that the hydraulic pump, hydraulic motor or valve may be damaged or about to be damaged, if it is rubber, it means the hydraulic cylinder Damaged seal.

(2) Drain the fuel tank regularly

Releasing water and sediment in the oil tank regularly is very important for removing impurities in the oil, but it is also very important to regularly replace the hydraulic oil in the entire hydraulic system. This is the only a reliable way to completely remove system impurities, oxidized hydraulic oil and other harmful impurities. Then, clean hydraulic fluid recommended should be re-added to the hydraulic system.

Drain the dirt in the oil tank of the hydraulic tank every 250 working hours. We have Volvo Bucket Adapters on sale.

(3) cleaning

If the hydraulic oil is contaminated, especially when the pump, cylinder or the motor is damaged, all hydraulic oil must be replaced and the fuel tank must be cleaned.

Keep work area clean

When refilling or refilling the hydraulic tank with oil, make sure the area around the filter tank cover is clean.

Only use a clean funnel or container.

Do not bring dirt into the system.

When maintaining the hydraulic system, use only clean plastic plugs to seal the ends of the pipeline.

When maintaining hydraulic components, the workbench must be absolutely clean.

Check the condition of the tools used, they should also be very clean.
