HYDRAULICS
50) Lower the lift to the floor and raise the lift approximately one foot.
51) 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.
52) Raise lift 6 inches. Repeat step 50 until no air comes out of cylinder.
53) 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.
54) 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 appear to be leaking.
SYNCHRONIZING CABLES
55) Raise lift and ensure carriages lower into same lock position.
56) Adjust synchronizing cables so the tension is equal in both cables and carriages are firmly sitting on locks.
57) Cycle lift to ensure that locks operate simultaneously.

Model CL10A Installation, Operation and Maintenance

LIFTING A VEHICLE

LOSS OF POWER

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 2500 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. Raise the lift 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. Lower the vehicle until the locks on both columns engage. The vehicle should remain level when both locks 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 locks.
   Always lower lift into locks before entering the area beneath the vehicle. Always use support 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. Raise the vehicle until both locks are free.
8. Disengage the locks by pulling and holding 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.

If for any reason the lift will not raise off 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 and include a record of each planned maintenance activity and repair maintenance activity performed. Refer to the maintenance section of the ANSI/ALI ALOIM booklet (blue book) provided with the lift. · 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 lock release activation. When properly adjusted, the idler column lock should rest firmly against the back of the column when engaged and against the spring mount tab when disengaged. 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. If both threaded ends of either cable have run out of adjustment, then replace both cables. (Cables should always be replaced in sets.) Monthly · Torque concrete anchor bolts to 80 ft-lbs. · Visually inspect concrete floor for cracks and/or spalls 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.) · Lubricate arm using the grease fittings. If any problems are encountered, contact your
local service representative.
