Operating Instructions

Bleeding the Hydraulic System

If the jack does not appear to be working properly, it may need to be bled of excess air:

1. Check the oil level.
2. Place the handle over the release valve and open it by turning counterclockwise.
3. Insert the handle into the fulcrum and pump about five times.
4. Apply pressure to the saddle and pump the handle quickly several more times to remove trapped air.
5. Use a flat dull-sided edge to push down the top inside rim of the oil fill plug to equalize pressure, then release.
6. Turn the handle clockwise to close the release valve and test the jack.

Lifting

1. Set the jack on a flat, level, solid surface.
2. Close the release valve by turning the handle clockwise.
3. Position the saddle under the vehicle manufacturer's recommended lifting point. Use the elevating screw to adjust the height if necessary.
4. Pump the handle using smooth, full strokes.
5. Once raised, slide jack stands of appropriate capacity under the vehicle.
6. Lower the vehicle onto the jack stands.

Lowering

1. Remove all tools and parts from under the vehicle.
2. Position the saddle under the lifting point and pump slightly to raise the vehicle off the jack stands.
3. Remove the jack stands.
4. Slowly turn the release valve counterclockwise (never more than two full turns) to lower the vehicle to the ground.

Maintenance and Servicing

• Inspection: Before each use, check for broken, cracked, or bent parts, and loose or missing components. Do not use damaged equipment.
• Oil Level: Check before each use. With the jack upright and level, remove the oil fill plug. The oil should be level with the bottom of the fill hole.
• Oil Change: Change the hydraulic oil at least once every three years. Drain old oil, refill with high-quality hydraulic jack oil until it reaches the fill hole, and bleed the system.
• Cleaning: Clean with a clean cloth and detergent or mild solvent. Store in a safe, dry location.

Troubleshooting

• Jack will not lift: Check that the release valve is closed fully.
• Saddle lowers under load: Valves may be blocked. Lower the saddle, close the valve, manually lift the saddle, then open the valve and force the saddle down quickly to flush the valves.
• Pump feels spongy: The jack may require bleeding.
• Oil leaking from fill plug: Unit may have too much hydraulic oil; check fluid level and adjust.
