the full raised height of the lift.
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, a pad may
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.
A qualified person should be consulted to address
seismic loads and other local or state requirements.
Failure by purchaser to
provide the recommended
mounting surface could result
in unsatisfactory lift performance, property
damage, or personal injury.

height.
5) Lower the vehicle until the safety 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 safety stands when removing or
installing heavy components.
LOWERING AVEHICLE
1) Insure that the area under the vehicle is clear of
personnel and tools.
2) Raise the vehicle until both locks are free.
3) Disengage the locks by pressing and holding the
lock release palm button.
4) Lower the vehicle by depressing the lowering
valve handle.
5) Continue to lower the vehicle until the carriages
stop against the base plate. Retract the extension
arms, and park them.

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 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.
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.
