1. Regularly add grease

When the product is put into use, it should be filled with new grease according to different working conditions. The slewing bearing should be filled with grease regularly. According to different types of slewing bearings, the specific filling time of grease is as follows:

(2) Roller type: add grease every 50 hours of operation;

If it is in a special working environment, such as: tropical, high temperature, dusty, high temperature, and continuous work, the grease filling cycle should be shortened, and it should be ensured that it should be filled every 50 hours; Apply detergent once every 150 hours. When working vigorously, apply detergent every 75 hours. Note that the teeth must be wiped clean before applying detergent.

The machine must be filled with new grease before and after the machine has been stagnant for a long time.
