Can I use this jack on uneven concrete or dirt?

Place this jack only on solid, level surfaces. Soft ground or slopes compromise stability. Always use jack stands rated for your vehicle's weight in addition to the jack itself.

Do I need to add hydraulic fluid, or does it come ready to use?

Mounting method and fluid status not specified in product data. Test-fit and verify fluid levels before your first lift. Check the valve and pump for leaks before committing to heavy work.

What's the return process if the jack doesn't work when it arrives?

Contact customer service with photos of the issue and your order number. Most mechanical failures are covered within the standard return window if damage is not visible on arrival.
