Basic Alignment Procedures
Positioning the Vehicle on the Lift
Proper vehicle positioning on the alignment lift is an
important step for safety and accuracy.
1. Make sure the front turntable and rear slip plate
locking pins are in place.
NOTE: Steps 2 - 5 are recommended to make sure the front
tires are placed in the center of the turntables.
NOTE: If an optional drive-on camera aid is available
proceed to step 2, if not available skip to step 3.
2. From the Home Screen click on the “Rack Drive-on
Aid” icon located on the upper tool-bar. View the
screen while positioning the vehicle.
3. Drive the vehicle onto the alignment lift and stop
just before the turntables. Take care to insure the
vehicle is centered on the runways.
4. Place the vehicle in park (or in gear on a standard
transmission), turn the ignition off, and set the park-
ing brake on. Place wheel chocks behind the tires
to prevent rolling.
Failure to use the wheel chocks can allow the vehicle to
roll off the rack/lift.
5. Position the turntables as needed to insure the tires
will be centered.
6. Drive the vehicle forward onto the center of the
turntables.
Alternative Method: This method extends turntable life due
to relief of load and stresses encountered when the brakes
are applied (or acceleration on a FWD vehicle).
7. Place the vehicle in neutral, release the parking
brake, and pull or push the vehicle forward onto the
turntables. Reposition the wheel chocks, place the
vehicle in park, reapply the parking brake.
To avoid personal injury or damage to property, follow
the rack/lift manufacturer’s operating and safety proce-
dures.
8. Raise the alignment lift, then lower the lift onto its
mechanical stops.
9. Place the transmission in neutral and release the
parking brake just before beginning the Vehicle
Positioning process.
