Do I need to use jack stands with this jack?

Yes—never work under a vehicle supported only by a jack. Always use jack stands rated for the same load capacity as a safety backup. A hydraulic jack is a lifting tool, not a support system.

What maintenance does this jack need?

Check the hydraulic fluid level before each use and top up if needed. Keep the pump clean and store in a dry location. If the jack loses pressure or won't lift, the hydraulic seal may need attention—have it serviced by a qualified technician.

Can I use this jack on uneven surfaces?

No. Always place the jack on a flat, level, solid surface—concrete or asphalt preferred. Uneven ground can cause tipping or uneven load distribution, which creates a safety hazard.
