CAUTION
Before using this product, read and fully understand the operating
instructions and all decals on the product. This is necessary to
prevent injury to the operator and damage to the product.
Roll jack forward before moving vehicle on or off lift.
Do not attempt to use this jack for anything other than its intended
purpose.
If jack begins to tilt as the vehicle is raised, STOP! Lower jack and
reposition the vehicle.
Do not use this jack if it is visibly worn, distorted or damaged.
Maximum air operating pressure not exceed 150 p.s.i.
Always wear appropriate eye protection.
WARNING
Lifting capacity of this jack is 7500lbs (Hydraulic Pressure at Cap. = 5500 psi)
Exceeding this could result in severe personal injury or death.
When the total lifting capacity of 2 rolling jacks differs from the rated
capacity of the lift they are used on, the capacity of each jack should
not exceed 1/2 the total capacity of the runways. Exceeding this could
result in severe personal injury or death.
Lift vehicle at manufacturer’s recommended pick-up points only.
Vehicle weight must be evenly distributed on each jack lift pad.

Loss of power
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.
Adjusting the Release Mechanism
1) Loosen the “Adjusting Screw”
2) Verify that the “Adjusting Plate” is free.
3) Depress the “Air Inlet Stem” with the “Foot Pedal”. The pump will now run and build
pressure.
4) Release the “Foot Pedal”. The pump will stop running, but hydraulic pressure will be
held.
5) With the “Foot Pedal” resting on the “Air Inlet Stem” rotate the “Adjusting Plate”
clockwise until a stop if felt.
Note: If the end of the slot in the “Adjusting Plate” is met before a stop is felt, the
“Adjusting Plate” must be repositioned one step counterclockwise on the “Hex Stem”,
then repeat step #5.
6) Tighten the “Adjusting Screw”. The release mechanism is now properly set.
Maintenance
Daily:Inspect jack and it’s components for damage or excessive wear. Replace parts as
required. See parts list.
Inspect air/hydraulic system for leaks. Check in-line lubricator oil level.
Annually: Check hydraulic pump fluid level. When jack is completely lowered remove
breather plug and check oil level. Oil should be at top of filler plug hole.
IMPORTANT!
Failure to keep lift free of corrosive agents and solvents will lead to reduced service life, which
could result in property damage and/or personal injury. If any problems are encountered,
contact your local service representative.
