1. Maintain the Tunnel Mucking Machine 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 Tunnel Mucking Machine is equipped with a breaker, the hydraulic oil deteriorates and the replacement cycle should be shortened.
2. 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.
