3. Attach a 15ft. clear bleeding hose to the same fitting, and place the open end of the
hose into the power pack’s reservoir’s filler neck or in a container in which the oil
came in for reuse. Hose should be secured during the bleeding procedure.
4. Close the by-pass valve, and power up until the power side carriage reaches the
carriage stops.

15
5. Open the by-pass valve, and power up until oil is seen flowing out of the bleeder hose.
(No Air Bubbles). Bleed at least 1 gal. of hydraulic fluid through the system.
6. Remove the bleeding hose and reinstall the bleeder cap. Replace breather/filler cap.
7. Power up until slave side carriage reaches the carriage stops.
8. Close the by-pass valve and lower lift (both sides) until both carriages are fully
collapsed. Power up and lower (14”) lift a few times. When lift is fully down, open
the by-pass valve and raise the slave side 2-3” higher than the power side. Close the
by-pass valve.
9. Power up, and lower lift onto the first safety, on the power side. Open the by-pass
valve and lower slave side onto the same first safety. Close the by-pass valve. Lift is
now synchronized hydraulically.
10. Both power and slave sides must be completely down.
11. Check and add hydraulic fluid to power pack before cycling lift.
12. Install safety covers, and safety release lever knob. Securely.
13. After anchoring, set up a vehicle on the lift to make sure hydraulics are operating
properly.

16
5.12 HYDRAULIC ADJUSTMENT PROCEDURE
Important! Should your lift come out of synchronization, i.e. one carriage is higher than
the other, it is necessary to level the lift hydraulically.
When slave side is higher than the power side:
1. Lower lift on to the first safety on the power side.
2. Open by-pass valve. Push the down control lever. This will cause the slave side
carriage to be lowered. Stop lowering when the slave side carriage stops on the first
safety.
When power side is higher than the slave side:
1. Open the by-pass valve, raise lift until the slave side carriage is approximately 1-2”
higher than the power side carriage. Stop raising and close by-pass valve.
2. Lower lift by pushing the down control lever. Stop lowering when the power side
carriage touches the first safety.
3. Next, open the by-pass valve. Push the down control lever so that the slave side
carriage lowers. Stop lowering when the slave side carriage touches the first safety.
Close the by-pass valve.
5.13 TOWER POSITIONING AND ANCHORING
WARNING! Failure to follow these instructions may cause an unsafe operating
condition.
WARNING! Before proceeding with installation, review Section 4: Installation
Requirements & Tools.
1. Using a 4ft. level on top of the crossmember, determine which column is higher
(Figure 13).
2. Using 2 ft. level on the sides of the high column, ensure that the column is level in
the vertical position (Figure 14). Use shims under the column baseplate to hold
the column level. Ensure that the base plate is completely supported by shims
where it does not contact the floor (Figure 15).
WARNING! Do not use more than ½” (13mm) of shims. Anchor bolts supplied
allow for a maximum of ½” (13mm) of shim. If more than ½” (13mm)
of shims are required, DO NOT proceed with installation and contact
