4. Place a Level target on the right/front corner of the
runway. (See Fig. 7.)
5. Beginning with “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 cross hairs of the Level,
(See Fig.17.1)
Note:
Use a pencil, marking pen or attach a paper clip
onto the target scale at the crosshair reference.
6. Next, move the target and place it at point “B” on the
runway. (See Fig. 17.1)
7. Rotate the Level and focus on the target scale.
8. Adjust the adjustment nut on the safety ladder bar at the
top of the column at “B” until the crosshairs of the Level
align to reference mark on the target scale. (See Fig. 17.1)
9. Repeat steps locating the target assembly at points “C”
and “D” and adjusting safety ladders at each correspon-
ding column until the reference mark on the target scale
is on the crosshairs of the Level. The runways are now
level at all four points. (See Fig. 17.1)
10. To complete the leveling procedures, lock each safety
ladder jam nut tightly against bottom of column top plate.
(See Fig. 17.2)
11. Next, load vehicle onto the lift.
12. Raise the lift to full height. Listen and watch as the
primary safeties engage the safety ladder. Synchronize by
adjusting the cables so that all four latches click at same
time. Make necessary adjustments to the cables allowing
compensation for stretch.
Safety locks may not engage at exactly the same time
when vehicles are being raised. They should be close.
Be sure that all four corners have passed the SAME
safety ladder bar slot before lowering lift on the safety
locks. NEVER lower lift on different safety lock position
or damage to the lift may result.
STEP 18
( Bleeding )
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 down. 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, run lift to full rise and run motor
for approximately 3-seconds after lift stops. This will place
pressure on the hydraulic system. Stop and check all fit-
tings and hose connections. Tighten or reseal if required.
