STEP 17
( Leveling / Synchronizing )
1. Using an engineer’s automatic Level (transit), locate
the Level at a convenient location in the shop that allows
an unobstructed view of all four corners of the runways.
2. Follow the Level manufacturer’s instructions for
proper setup of the Level. Be sure it is adjusted level in
all directions.
3. Raise the lift approximately 30”- 40”. Then lower the
lift until all primary safeties are engaged in each column
and the runways are completely resting on the primary
safeties.
4. Place a Level target on the right/front corner of the
runway. (See Fig. 17.1)
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 cross hair 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 cross hairs 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 cor-
responding Column until the reference mark on the target
scale is on the cross hairs 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.
13. Install the four Cross tube Covers. (See Fig. 17.3)
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-
bleeding. After bleeding system, fluid level in Power Unit
reservoir 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 put pres-
sure on the hydraulic system. Stop and check all fittings
and hose connections. Tighten or reseal if required.
