5. Beginning with the “A” position, sight the Level to the
target and mark the number or the graduation on the inch
scale of the target that aligns to the crosshairs of the Level.
(See Fig. 16.1)
6. Next, move the target and place it at point “B” on the
ramp. (See Fig. 16.1)
7. Rotate the Level and focus on the target scale.
8. Adjust the Adjustment Nut on the Safety Ladder at the
top of the post at “B” until the crosshairs of the Level align
to reference mark on the target scale. (See Fig. 16.1)
9. Repeat steps locating the target assembly at points
“C” and “D” and adjusting Safety Ladders at each corre-
sponding post until the reference mark on the target scale
is on the crosshairs of the Level. The ramps are now level
at all four points. (See Fig. 16.1)
10. To complete the leveling procedures, lock each Safety
Ladder jam nut tightly against bottom of Post Top Plate.
(See Fig. 16.2)
11. Next, load vehicle onto the lift.
12. Raise the lift to full height. Listen and watch as the Pri-
mary Safeties engage the Safety Ladders. Synchronize by
adjusting the cables so that all four latches click at same
time. Make necessary adjustments to the cables allowing
compensation for stretch.
STEP 17
(Bleeding the Cylinder)
1. Lift must be fully lowered before changing or adding
fluid.
2. Raise and lower lift six times. The cylinder is self-bleed-
ing. After bleeding system, fluid level in Power Unit reser-
voir may be low. Add more fluid if necessary to raise lift to
full height. It is only necessary to add fluid to raise lift to full
height.
3. To pressure test, raise lift to full rise and run motor for
approximately 3-seconds after lift stops. This will put pres-
sure on the hydraulic system. Stop and check all fittings
and hose connections. Tighten or reseal if required.
