GENERAL SPECIFICATIONS

• Lift capacity ratings are based on loads equally distributed on all fourarms.
  Lifting and lowering speeds may vary depending on weight of vehicle.
  VERTICAL CLEARANCE
  Check the height of the area where the lift is to be installed. Clearance should be calculated based on the full raised height of the lift.
  WARNING
  Failure by purchaser to provide adequate clearance could result in unsatisfactory lift performance, property damage, or personal injury.
  FLOORING
  Be certain you have the proper concrete floor to properly handle the loaded lift. Floor should be in generally good condition with no large cracks, spalling or deterioration.
  Minimum requirements for concrete are 4 inches minimum depth, with steel reinforcement, 3500 PSI, cured for 28 days per local commercial practice.
  Floor should be level within 3/8 inch over the installation area. No anchors should be installed within 8 inches of any crack, edge, or expansion joint. If these conditions cannot be met, pads can be poured to accommodate the lift.
  Check with local building inspectors and/or permits office for any special instructions or approvals required for your installation.
  WARNING
  Failure by purchaser to provide the recommended mounting  surface could result in unsatisfactory lift performance, property damage, or personal injury.
  ELECTRICAL REQUIREMENTS
  For lift installation and operation for single phase units, it is necessary to have a dedicated circuit with a double pole 25 amp circuit breaker or time delay fuse.

Layour

1. Layout the service bay according to the architect’s plans or owners instructions. Be certain that the proper conditions exist.

2. Assemble column extension to column using M12x30 Hex bolt. Repeat for opposite columnand extension.

3. Using the Overall Width(C) as a guideline, chalk two parallel on the concrete floor within 1/8 inch tolerance.

4. Determine the location of the Column Ass’y on either chalk line and mark the base plate dimension Overall Width(L) . TOOLS WARNING
   Be sure to stay within a 1/4 inch overall tolerance. This will eliminate any difficulty in final assembly or possible premature chain wear or misalignment.
   The chalk line layout is very important. If it is not followed accurately problems may arise in final assembly and operation.

5. Using a lifting device, Erect both column assemblies with the installation lines.
   ANCHORING

6. The anchor bolts must be installed at least 8 inches from any crack, edge, or expansion joint.

7. Use a concrete hammer drill with a 5/8 inch carbide bit. Do not use excessively worn bits or bits which have been incorrectly sharpened. A core bit may be necessary if an obstruction is encountered.
   Never substitute with shorter anchor.

8. Vacuum dust from the hole for proper holding power.

9. Shim both columns to plumb using the shims provided. DO NOT shim more than 1/2″ at any given point. Use a level no less than 24 in length to plumb columns.

10. Assemble washer and nut to anchor with nut just below impact section of bolt. Drive anchor into hole until nut and washer contact base.

11. Tighten power column anchors and recheck column for plumb. Reshim if necessary. Torque to 150 foot pounds to set anchors.
    WARNING Never remove the lift before the columns Tightened by the anchor bolts.
    FLOOR-PLATE

12. Assemble floor-plate ass’y to floor.
    SYNCHRONIZER CABLES

13. Manually raise the carriages until each is located on the second lock position.

14. Route synchronizing cables using Fig 4 and attach ends to carriages’ joining using Fig’s 5.

15. Adjust cable tension by adjusting each cable’s adjustment nuts. The cables should be tight with no slack. Each cable should be the same tension. Be sure as you are tightening the cables that they have remained in place over the pulleys. Failure to do this will result in damage to the cable. WARNING
    Prior to operation of lift recheck equalizer cables making sure they are not crossed or routed improperly. Be sure the cables have remained in place over the pulleys.
    POWER UNIT & HYDRAULIC HOSE

16. Mount Power Unit to power column as shown in Fig 6 The mounting hardware, M8 hex nuts, are pre- installed on power unit mounting bracket.

17. IMPORTANT – To insure proper hose fitting seal without damage to the fitting follow this procedure for each hose connection: Screw flared fitting on finger tight. Rotate flared fitting 1 1/2 hex flats (90 deg.). Back the flared fitting off one full turn. Again tighten flared fitting finger tight, then rotate flared fitting 1 1/2 hex flats (90 deg).

18. Thread power unit hydraulic hose into elbow on power unit. Route hydraulic hose from Idler column across floor plate ass’y to the Power Column. (Fig 6)

19. Once the Power Unit is secured, fill reservoir with #10 weight HYDRAULIC OIL ONLY. Care should be taken to keep dirt or other contamination out of oil.
    ARM INSTALLATION

20. Lubricate the arm pin or carriage arm pin hole with “anti-seize” and install the arms. Insure that the arm restraint gears engage and disengage properly. Arm restraints any binding occurs, insure that the large gear mounted to the arm has been factory installed tight against the arm pin.
    FINAL ADJUSTMENTS

21. Lower the lift to the floor and raise the lift approximately onefoot.

22. Start with Idler side first. Slowly and carefully loosen the bleed plug on top of the cylinder just enough to allow the entrapped air to escape. Repeat for powerside.

23. Energize the power unit and raise 6 inches. Repeat previous step until no air comes out of cylinder.

24. Pressure test hydraulic system. Energize power unit, raise lift to full rise and continue to run motor for additional 10 seconds. (NOTE: pressure relief will make a high pitch squeal sound for these 10 seconds.) Check hydraulic system for leaks.

25. Energize power unit again for 10 seconds. With a clean rag, wipe down both cylinder rods. If lubricant is not wiped clean from the cylinder rod, the cylinder will appear to be leaking.

26. Cycle lift to insure that the latches operate simultaneously. Lower the lift onto the locks and insure that neither lock will wobble (it is possible for the carriages to appear to be resting on the locks when actually only one carriage is resting on its lock and the other carriage is being supported by the synchronizing cable).

27. Lower lift to the floor. Pull and release lock release handle while watching idler column lock. Adjust threaded sleeve cable adjuster nuts until idler column lock disengages and engages fully. When properly adjusted, the idler column lock should just come to rest against the back of the column when engaged and fully out against the tab when disengaged.
    IMPORTANT: IF IDLER SIDE LOCK PAWL DOES NOT FULLY DISENGAGE, DAMAGE MAY RESULT TO IDLER SIDE CARRIAGE AND OR CABLE SYNCHRONIZING SYSTEM.

28. Tighten and trim wire ties.

29. Snap lock cover over each lock assembly.
