1. Always pay attention to the lubrication of the friction surface in time, which can ensure the normal operation of the jaw crusher and prolong its service life.

2. The lubricating grease used in this jaw crusher should be determined according to the use place and temperature. Generally, calcium-based, sodium-based or calcium-sodium-based greases can be used.

3. The grease added to the bearing seat is 50-70% of its volume, which must be replaced every three months. When replacing new oil, clean gasoline or kerosene must be used to clean the dirt in the bearing and bearing seat.

The contact between elbow plate and elbow pad must be greased before the jaw crusher starts.
