Operation
Note: Before lifting a vehicle, operate the jack through a couple of cycles to become familiar
with the controls.
1) Roll jack forward before moving vehicle on lift rack. Be sure vehicle is centered on
rack, apply parking brake and chock wheels.
2) Roll jack(s) to the vehicle manufacturer’s recommended pick-up points. Extend lift
pad arms to proper lift points. Use lift pad spacers if necessary.
3) Raise jack by pumping the jack handle.
4) Raise vehicle to desired height.
5) Lower jack onto lock.
6) To lower jack completely, raise off of lock and turn the valve handle counter
clockwise. Push lift pad arms in, remove lift pad spacers (if used). Roll jack forward
before moving vehicle off rack.
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.
Maintenance
Daily:Inspect jack and it’s components for damage or excessive wear. Replace parts as
required. See parts list. Inspect hydraulic system for leaks.
Annually: Check hydraulic pump oil level if jack is not achieving full rise height. When jack is
completely lowered, remove pump from base, hold pump vertical then remove breather
plug (knurled screw on pump end) and check oil level. Oil should be at top of filler plug
hole. Recommended Oil : AW32- 10wt hydraulic oil, non-foaming, anti rust.
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.
