Operation
To raise the Positioning Jack to support a Vehicle:
1. Drive the Vehicle to the desired location, set the parking brake, put the Vehicle in Park or in first
gear, if it has a manual transmission.
2. Remove the Lock Pin from the Frame.
3. Open the Release Valve by turning the Release Valve Knob counterclockwise.
⚠
CAUTION
4. Expand the Positioning Jack by pulling the Rollers apart. The Rollers should be wide enough to
straddle the Tire.
5. Position the Positioning Jack so that both Rollers contact the Tire Tread. Verify there is at least .75"
clearance between the Tire and the Frame of the Positioning Jack, as well as full contact of the Tire
to the Rollers. This assures the Tire will contact the Rollers and not the Frame of the Dolly as it is
raised.
6. Close the Release Valve by turning the Release Knob clockwise until finger tight. Do not over-
tighten the Release Valve.
7. Operate the Foot Pedal to lift the Tire until it just clears the floor.
8. Check the Vehicle for stability.
If the Vehicle is
down to the ground and reposition the Positioning Jack.
9. When the Lift is complete and the Vehicle is stable, place the Lock Pin in the Hole closest to the
Extension Rod Frame.
10. Use the Stow Hook to secure the Foot Pedal in the down position.
11. Repeat for the remaining Positioning Jacks.
To lower the Positioning Jack:
1. Verify that it is safe to lower the Vehicle. Verify that no personnel are near the Vehicle, no tools,
equipment or other unsafe conditions are present underneath the Vehicle.
2. Remove the Lock Pin. If the Lock Pin is wedged in the Jack Frame, carefully remove the Foot
Pedal Stow Hook (the Pedal is Spring-loaded) and operate the Pedal enough to relieve the
pressure on the Lock Pin.
3. Slowly open the Release Valve by turning it counterclockwise until the Tire rests on the Floor.
4. Carefully remove the Car Dolly Jack from the Tire and store it.
