The controlling devices, hand wheels, and crank handles are mounted on both sides of the table and can be controlled from either side 

1. Hand Wheel（B）and Hand Wheel（H）are mounted on the left side and the right side of the table for adjusting the back section and the seat section respectively from either side of the table. 

2. On the right side of the table, Crank Handle （G）is used for lateral tilt in the left or right direction, and Crank Handle （A）is employed for adjustment of the kidney bridge.

3. Crank Handle （F）located on the right side of the table, is used to control Trendelenburg and reversed Trendelenburg positions. It is detachable and can be mounted on the left side.

4. Both the ascending and descending movements of the table top are controlled by the oil pump. When the products leave the factory, the oil in the oil pump has been pumped into the pail, so the oil pump can not ascend. The consumers must loosen the cover of the filling aperture at the top of the oil pump and try to use the oil in the pail to refill the oil pump through the filling aperture slowly. By pressing down Pedal（C）repeatedly, the table top will elevate and stop automatically when the maximum height is reached. When the pedal is pressed down to its limit, the tabletop will begin to descend slowly and gently.

5. The base of the table is mounted on ball-bearing castors and controlled by the floor brake so that the table can be freely moved or stabilized at any desired position. When Pedal（E）is pressed down gently, the table can be pushed easily, and when the same pedal is pressed down again, the base will be set stably on the floor.
