\u25cf The gear oil viscosity grade used for the power take-off (PTO) box is SAE 90 API GL-4 transmission oil (Shell VG150 gear oil is filled at the factory); it is required to replace the oil every 500 hours of pumping or every six months.<\/p>\n

\u25cf The lubricating oil level must not exceed the liquid level of the oil level port; otherwise, it will cause abnormal heating of the PTO box, damage the cylinder seals of the input and output shafts, and affect the lubrication effect.<\/p>\n

\u25cf It is required to inspect the connection bolts of the PTO box and the bracket bolts once a week to prevent damage to the PTO box caused by increased vibration frequency of the transmission shaft due to loose bolts!<\/p>\n

The Replacement Method of Gear Oil for the Power Take – Off (PTO) Box<\/h2>\n

1. Switch the\u00a0\u00a0\u6cf5\u8f66<\/strong><\/a>\u00a0 to the pumping state and let it idle for ten minutes.<\/p>\n

2. Stop the machine, unscrew the oil drain plug of the power take-off (PTO) box, and allow the lubricating oil and dirt inside the PTO box to flow out together.<\/p>\n

3. Tighten the oil drain plug.<\/p>\n

4. Unscrew the ventilation cover, add new oil through the oil filler port at the ventilation cover, and ensure that the lubricating oil level does not exceed the liquid level screw.<\/p>\n
