Bleed The Hydraulic System
EQUALIZER VALVES ON THE HYDRAULIC EQUALIZATION CIRCUIT MUST REMAIN IN THE
CLOSED POSITION DURING NORMAL OPERATION. FAILURE TO CLOSE VALVES DURING
NORMAL OPERATION MAY DAMAGE LIFT STRUCTURE.THE FOLLOWING PROCEDURE
SHOULD BE PERFORMED WITHOUT LOAD ON THE LIFT.
1. With the lift in the fully lowered position, place the valve handles on the hydraulic equalization
circuit until both handles are PARALLEL with the valve body that is OPEN position.
See Figure 17 (a).
2. Raise the lift to the maximum raised position, the runways may raise unevenly during this time.
3. Raise the lift until both runways reach full height and cylinders are at maximum extension.
Once the lift stops raising, continue pressing the "UP" button for 15 seconds to fill all the
cylinders with hydraulic oil.
4. After the cylinders are filled, position the handles on the hydraulic equalization circuit back to
the CLOSED position - PERPENDICULAR WITH THE VALVE BODY. See Figure 17 (b).
5. Press the mechanical safety release button and lower the lift to the fully lowered position.
6. Raised the lift midway and lower onto a safety lock position.
7. After a visual confirmation that both sides are on the Same Lock Position. Open both valve
handles, you may hear a "swoosh" as the fluid in all four cylinders equalizes. Once this is done
(about 10 seconds later) close the valve handles.
8. Your lift should now be equalized. Be sure to repeat this procedure step 1-7 if the lift
requires equalization in the future.
