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. 16.1)
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. 16.1)
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 hair 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 cor-
responding Column until the reference mark on the target
scale is on the cross hair of the Level. The runways are
now level at all four points. (See Fig. 16.1)
10. To complete the leveling procedures, SNUG EACH
SAFETY LADDER JAM NUT against the bottom of the
Column Top Plate. (See Fig. 16.2)
11. Next, load vehicle such as an RV onto the lift.
12.
Raise the lift to full height. Listen and watch as
the locking latches click in place. SYNCHRONIZE BY
ADJUSTING THE CABLES so that all four latches click
at the same time. Make necessary adjustments to the
cables allowing COMPENSATION FOR STRETCH.
Safety locks may not click in 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 17
(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
allow full height raise.
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.
