Third, the lubricating oil is fed according to the regulations, and the venting air holes and one-way valves are regularly cleared.

Fourth, assembly under clean conditions, no bumps of parts work surface, no scratches, burrs and other attachments;

Fifth, strict operating procedures, the seal should be properly installed, preventing non-inverting deformation;

Sixth, master the performance specifications and requirements of the seal, and replace the lost effect in time;

Seventh, for the side cover thin-walled parts, using sheet metal cold to correct; easy to worn shaft hole parts can be used for metal spraying, welding, adhesive, machining, etc. to achieve original size;

Eighth, the nut wire buckle, loose should be repaired or replaced, and screwed to the prescribed torque.
