Initial Operation
EQUALIZER VALVES ON THE HYDRAULIC EQUALIZATION CIRCUIT MUST REMAIN IN THE
CLOSED POSITION DURING NORMAL OPERATION. REFERENCE FIGURE 17 (b).
REAR BOLSTER BAR AND JACK BEAMS CANNOT BE INSTALLED UNTIL THE LIFT HAS
BEEN BLED.
THE FOLLOWING PROCEDURE SHOULD BE PERFORMED WITHOUT LOAD ON THE LIFT.
1. Fill hydraulic fluid in reservoir (ISO 32 10wt). Oil capacity for the lift is approximately 4 gallons.
Make sure the funnel used to fill the power unit is clean and incorporates a filter device.
2. Connect shop air to the inlet port at the FRL unit in the console.
3. Raise lift by pressing the up button located on the front of the console.
Raise the lift approximately 4 ft and check all the hoses at the lift for any hydraulic leaks.
4. Continue raising the lift slowly and monitoring the fluid level in the reservoir at same time,
add hydraulic oil if necessary, until the lift cylinders reach their maximum extension.
• During this stage the secondary cylinders are not yet full of oil. During the
following steps, one side of the lift may raise higher than the other.
5. Press the mechanical safety release button and then lower the lift by pressing the down
button. Bring the lift to the fully lowered position.
6. Repeat this process at least three times to equalize the oil pressure in each cylinder.
