Frequently Asked Questions (FAQ)
-
Q: What is the lifting capacity of the WW 6490 floor jack in pounds?
A: The jack has a rated capacity of 3 tons, which is equivalent to 6,000 pounds (2,722 kg). It is designed for regular passenger vehicles, SUVs, and light trucks within this range. -
Q: Does the jack come pre-filled with hydraulic oil?
A: Yes, the hydraulic system is pre-filled and sealed at the factory. Simply remove the air plug, pump a few strokes to prime, and it’s ready for use. Additional oil can be added if needed. -
Q: What is the minimum clearance required to slide the jack under a vehicle?
A: The minimum lifting height is 5.5 inches (140 mm), making it suitable for low-profile vehicles. For cars with lower ground clearance, we recommend checking the frame clearance before purchase. -
Q: How does the safety valve work?

Q: What maintenance does this floor jack require?

Q: Can I use this jack for commercial or industrial daily operations?
A: Absolutely. The robust steel construction and safety valve make it suitable for daily use in auto repair shops, service centers, and industrial maintenance facilities. It meets common workshop safety standards. -
Q: Do you offer warranty and after-sales support?
