1. Maintain the tunnel mucking loader according to the regulations, replace the hydraulic oil and oil return filter periodically, and pay attention to whether the filter element is absorbing iron filings and dust. If the mucking machine is equipped with a breaker, the hydraulic oil deteriorates and the replacement cycle should be shortened.
2. The hydraulic oil is not enough for the Tunnel Mucking Machine. If the hydraulic oil is insufficient, the temperature of the tunnel mucking machine will be too high and the machine will be weak.
3. After replacing the hydraulic oil or hydraulic components, pay attention to drain the mucking loader air.
4. Hydraulic oil should be purchased by regular channels. Before adding new hydraulic oil, it is best to let all the hydraulic oil in the Tunnel Mucking Machine hydraulic tank be discharged. If there is less oil in the hydraulic tank, add some more. This is an incorrect method and a wrong idea. Because the pollution in the roadway is relatively large, the hydraulic oil in the hydraulic tank is already polluted, so it is best to use 200 hours for hydraulic oil change. Left or right or about 2 months, completely replace it once and keep the hydraulic system clean.
