What to do if my BIG RED JACKS jack will not lift the load?
- RRebecca ComptonJul 28, 2025
If your BIG RED JACKS jack isn't lifting, several factors could be at play. First, ensure the release valve is completely closed by turning the handle clockwise. It's also possible the weight capacity has been exceeded. Air in the hydraulics can also cause this issue, so try purging the air from the system. Check the oil level and add oil if it's low. A binding jack or foreign obstruction could be the cause. In some cases, a malfunctioning power unit may need replacement.
