Before assembling the slewing support, the support should be de-stressed to reduce the deformation of slewing support. The contact surface between the support and the slewing support must be cleaned during assembly 2. Attention should be paid to the changes in noise and rotary resistance torque changes, if there is abnormal phenomenon should be removed 3. The slewing support must be lifted or stored horizontally.
