LAYOUT
Note:
This lift can be installed at two different heights and three different widths. The Cable adjustment for the Height and Width variations will be accommodated by the Lower Sheave Bracket.
The height and width must be established before beginning, as this will determine the lower sheave position.

1. Once the general location of the lift has been determined, ensure that the proper conditions exist per page 3.
2. Determine which side of the bay the power unit will be located and identify the column assembly with the power unit bracket.
3. Lay out the service bay according to the architect’s plans or owner’s instructions (see Fig 1b­Service Bay Layout). Failure to install in this orientation can result in personal and property damage.
   LIFT PREPARATION
4. With column assemblies lying flat, remove cable and hose rolls from inside the column.
5. Manually push carriages up enough to unhook the cylinder hose from the base plate tabs. Proceed with pushing the cylinder and carriage up enough to access all five sheave locations on the sheave bracket, see Fig 3.

Page 4

Rev. 01/23/2023
CL12-IOM-A.doc

Model CL12A Installation, Operation and Maintenance

6. Determine the sheave location on the lower bracket based on the overall height and width of the lift at its chosen configuration. Use the General Specifications table from page 2 and Fig 2 below.
   Note: The column has been assembled with the sheave in the highest position on the bracket for the lift installed at max height and max width.

7) The sheave must be removed and reassembled to route the synchronizer cable. Remove the bolt, sheave pin, bearing disc, sheave, and spacer bushing, Fig. 3.
8) Route a cable through a carriage and out the bottom. Route it back up and into the inside hole at the top of the carriage, see Fig 3. Ensure cables do not twist or wrap around hoses during routing.
9) Install a nut and jam nut at the cable end, Fig 3.
10) Reinstall the sheave. Place the bearing disc inside the bracket centered over the bracket hole based on the chosen install height. Install the cable on the sheave and slide into place. Stack the spacer bushing onto the sheave assembly. Still holding the sheave assembly, slide the pin into place and secure it with the bolt, see Fig 3.
11) Pull tension on the free end of the cable and ensure proper routing. While pulling tension on the cable, slide the cylinder and carriage down until the carriage is 8″ from the baseplate. Slide the hydraulic cylinder down and route the hydraulic hose around the hose guide tabs to prevent rotation of the cylinder, Fig 4. While pulling tension on the cable to avoid kinking, slide the carriage and cylinder down to base of lift.

ANCHORING
The anchor bolts must be installed at least 8″ from any crack, edge, or expansion joint. Recheck the area around both base plates.
Use a concrete hammer drill with a 3/4 inch carbide bit. Tip diameter should conform to ANSI Standard B94.12-1977 (.775 to .787). 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.
16) Recheck “Inside of Columns” dimension (Fig. 1).
17) Using the base plate as a template, drill one anchor hole. Drill through the floor if possible or to a depth of 5 inches minimum.
18) Clean the hole inside and out.
19) Assemble a washer and nut to the anchor with nut just below impact section of bolt. Drive the anchor into the hole until the nut is 3/4″ above the baseplate (leaving room for shims).
Complete steps 17 thru 19 for the six (6) exposed anchors (one at a time) around each column.
20) Raise both carriages (275 lbs. ea.) high enough to drill the two inner anchor holes on each column. Measure both carriage heights to ensure they are in the same lock position.
21) IMPORTANT: Place a safety support inside each column as a backup to the locks, since the hydraulic cylinders are no longer engaged with the carriages.
22) Repeat steps 17 thru 19 for the two (2) anchors under each carriage.
23) Shim both columns to plumb using the shims provided as shown in Fig. 7. DO NOT shim more than 1/2″ at any given point. Use a level no less than 24″ in length to plumb columns.
24) Drive all the anchors until nut and washer contact baseplate.

25. Tighten Power Column anchors and recheck column for plumb. Re-shim if necessary. Torque to 150 foot pounds to set anchors.
26. Loosen Idler Column anchors 1/8″ and proceed with the Overhead Beam installation.
    OVERHEAD 27) Before raising overhead into position install 4 (2
    per column) hex flange bolts and nuts in bottom hole of column extension (see Fig. 8 Installation Aid) for temporary support of overhead. Lift overhead assembly up into position and install with 8 each (4 per column) 3/8″-16 x 3/4″ lg. hex flange bolts and hex flange nuts per side as shown in Fig. 8. For the max width position, the outer overhead holes will be used. For the (-6″) width, use one set of outer overhead holes and one set of inner overhead holes. For the (-12″) width, use the inner sets of overhead holes.
    Fig. 8 ­ Overhead Assembly 28) Check idler column shimming. Use additional
    shims (see Fig. 7) to remove any gaps that may have been created while installing overhead beam. Tighten anchor bolts and re-check column for plumb. Torque to 150 foot-pounds.

FINAL ADJUSTMENTS
HYDRAULICS 68) Lower the lift to the floor and raise the lift
approximately one foot.
69) 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 power side.
70) Raise lift 6 inches. Repeat step 69 until no air comes out of cylinder.
71) 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.
72) Energize power unit again for 10 seconds. With a clean rag, wipe down both cylinder rods. (The cylinders are shipped with a small amount of clear anti- corosive lubricant that will be forced out through the wiper when the lift reaches full rise.) If lubricant is not wiped clean from the cylinder rod, the cylinder will apear to be leaking.
SYNCHRONIZING CABLES
73) Raise lift and ensure carriages lower into same lock position.
74) Adjust synchronizing cables so the tension is equal in both cables and carriages are firmly sitting on locks.
75) Cycle lift to ensure that latches operate simultaneously. Adjust if necessary.
LOCK RELEASE
76) Lower lift to the floor and snap plastic cover over Power Column lock assembly.
77) Pull and release Power Column lock release handle while watching Idler Column lock. Adjust lower threaded sleeve cable adjuster jam nuts on Idler Column 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. Tighten Idler Column lower tab jam nuts.
IMPORTANT: IF IDLER SIDE LOCK PAWL DOES NOT FULLY DISENGAGE, DAMAGE MAY RESULT TO IDLER SIDE CARRIAGE AND OR CABLE SYNCHRONIZING SYSTEM.
78) Tighten threaded sleeve cable adjuster jam nuts and install lock release knob.
79) Tighten and trim wire ties.
80) Snap plastic cover over Idler lock assembly (align release cable with notches in cover).

Model CL12A Installation, Operation and Maintenance

LIFTING A VEHICLE

1. Ensure that the lifting arms are parked, out to full drive thru position.
2. Center the vehicle between the columns in the service bay and position the vehicle’s center of gravity midpoint between the columns. NOTE: the center of gravity is based on the weight distribution and is not the same as the center point of the vehicle.
   DO NOT EXCEED 3000 POUNDS PER ARM.
   DO NOT ATTEMPT TO LIFT THE VEHICLE WITH ONLY TWO ARMS, AS THIS WILL VOID THE WARRANTY
   ENSURE THAT THE HIGHEST POINT ON THE VEHICLE WILL CONTACT THE OVERHEAD LIMIT SWITCH BAR.
   DO NOT PLACE THE VEHICLE IN THE SERVICE BAY BACKWARDS.
   REFER TO THE VEHICLE MANUFACTURERS SERVICE MANUAL, TECHNICAL BULLETINS, “VEHICLE LIFTING POINTS GUIDE” (ALI/LP-GUIDE) OR OTHER
   PUBLICATIONS TO LOCATE THE RECOMMENDED LIFTING
   POINTS.
3. Position the arms and adapters so all four pads contact the vehicle simultaneously.
   The vehicle should remain level during lifting.
4. Press the raise button until all four wheels are off the ground. Test the stability of the vehicle by attempting to rock the vehicle. Check adapters for secure contact with vehicle lift points. If the vehicle seems unstable, lower the lift and readjust the arms. If the vehicle is stable, raise the vehicle to a height a few inches above the desired working height.
5. Depress the lowering valve handle to lower the vehicle until the latches on both columns engage. The vehicle should remain level when both latches are engaged. If one side engages and the other continues to descend, stop lowering the vehicle, raise it several inches, and try again to engage both latches.
   Always lower lift into locks before entering the area beneath the vehicle. Always use safety stands when removing or installing heavy components.
   LOWERING A VEHICLE
6. Ensure that the area under the vehicle is clear of personnel and tools.
7. Press the Raise Button until both latches are free.
8. Disengage the locks by pulling down on the lock release lever.
9. Lower the vehicle by depressing the lowering valve handle.
10. Continue to lower the vehicle until the carriages stop against the base plate. Retract the extension arms, and park them.

LOSS OF POWER
If for any reason the lift will not raise off of the locks or the locks will not retract, consult factory authorized personnel.
DO NOT OVERRIDE ANY SAFETY FEATURE IN AN ATTEMPT TO LOWER THE LIFT.
MAINTENANCE To avoid personal injury, permit only qualified personnel to perform maintenance on this equipment. Maintenance personnel should follow lockout/tagout instructions per ANSI Z244.1.
The following maintenance points are suggested as the basis of a routine maintenance program. The actual maintenance program should be tailored to the installation. See ANSI/ALI ALOIM booklet for periodic inspection checklist and maintenance log sheet. If lift stops short of full rise or chatters, check fluid
level and bleed both cylinders per Installation Instructions.
Replace all Safety, Warning or Caution Labels if missing or damaged (See Installation instructions page 3.)
Daily Keep lift components clean.
Check for loose or broken parts.
Check hydraulic system for fluid leaks.
Check adapters for damage or excessive wear. Replace as required with genuine Challenger Lifts parts.
Check the lock release activation. When properly adjusted, both locks should be in a vertical position when lock release lever is pulled and should return to an engagement position when the lever is released.
Weekly Check synchronizer cables and sheaves for wear.
Replace as required with genuine Challenger Lifts parts.
Check synchronizer cable tension per Installation Instructions. Adjust if necessary.
Monthly Torque concrete anchor bolts to 80 ft-lbs.
Visually inspect concrete floor for cracks and/or sprawls within 12″ of base plate
Check overhead shutoff switch. While raising lift, operate overhead shutoff bar. Power Unit motor should stop when bar is raised.
Lubricate carriage slide tracks with heavy viscous grease. (Grease all (4) corners of both columns.)
If any problems are encountered, contact your
local service representative.
