Reducer use skills
1. After 200 to 300 hours of operation, the oil should be changed for the first time, and the quality of the oil should be checked regularly in the future use, and the oil mixed with impurities or deteriorated should be replaced in time. Under normal circumstances, for a long-term continuous working reducer, the new oil should be replaced by 5000 hours of operation or once a year, and the long-term deactivated reducer should also be replaced with new oil before re-operation. The reducer should be filled with oil of the same grade as the original, and should not be mixed with oils of different grades. Oils of the same grade but with different viscosities are allowed to be mixed for use;
2. When changing the oil, wait until the reducer has cooled down and there is no danger of burning, but it should still be kept warm, because after the complete cooling, the viscosity of the oil will increase and it will be difficult to drain the oil. Note: Cut off the power supply of the transmission device to prevent accidental power-on;
3. During work, when the oil temperature rises above 80°C or the oil pool temperature exceeds 100°C and abnormal noise is found, stop using it. Check the cause, remove the fault, and replace the lubricating oil before continuing to run. ；
4. The user should have reasonable use and maintenance rules and regulations. The operation of the reducer and the problems found in the inspection should be carefully recorded. The above regulations should be strictly implemented.

Reducer maintenance
Grease selection When selecting the grease according to the bearing load of the walking reducer, the grease with a small penetration degree should be selected for heavy loads. When working under high pressure, in addition to low penetration, it also has higher oil film strength and extreme pressure performance. Calcium-based grease has good water resistance, is not easy to emulsify and deteriorate through water, and can be suitable for the lubrication of various mechanical parts in humid environments or in contact with water. When selecting grease according to working temperature, the main indicators should be dropping point, oxidation stability and low-temperature performance. The dropping point can generally be used to evaluate high-temperature performance. The actual working temperature of the bearing should be 10-20°C lower than the dropping point. The use temperature of synthetic grease should be 20-30℃ lower than the dropping point.
It is forbidden to mix different lubricating oils with each other. The positions of the oil level plug, the oil drain plug and the breather are determined by the installation position.
