Installation Instructions for 12,000 lb Square Tube Jack
General Installation Notes:
- Follow all instructions provided without modifications.
- Never position any part of the body under the jack or the load being supported.
- Fully retract and/or rotate the jack before towing.
- Ensure the drop leg pin is fully inserted before using the jack.
- Block wheels to prevent rolling during operation or trailer coupling.
- Never exceed the rated capacity of the jack, footplate, or caster wheel. Refer to markings or decals for capacity limits.
- Avoid excessive side forces that may cause jack failure.
- Replace bent, broken, or worn parts before use.
- Use only on flat surfaces. For tandem applications, align jacks to share the load equally.
- All welding must be performed by an AWS-certified welder.
- Save these instructions for future reference.
Tools Required:
- Torque wrench
- Welding equipment (if applicable)
Step-by-Step Instructions:
Direct Mount to Load-Bearing Member:
- Welding must be performed by an AWS-certified welder.
- Apply three 2-inch-long 1/4” fillet welds on both sides of the jack along the contacting surface.
- Space the welds as far apart as possible for maximum load strength.
- For tandem applications, align the jacks carefully to ensure they raise and lower together, sharing the load equally.
Weld-On Pivot Tube Mounting:
- Weld the non-beveled side of the pivot tube to the trailer tongue using a 1/4” fillet weld.
- Align the pivot mount holes vertically.
- Mate the jack to the pivot tube and secure it with the supplied pin.
Drop Leg Operation:
Spring Return Drop Leg:
- Verify the jack is not under load.
- Place your foot on the footplate to control the drop leg's return.
- Rotate the drop leg pin to disengage and carefully move the leg to the desired position.

- If clearance exists between the pin and housing, lubricate and re-seat the pin.
Non-Spring Return Drop Leg:
- Verify the jack is not under load.
- Grasp the handle of the footplate to control the descent of the drop leg.
- Rotate the drop leg pin to disengage and move the leg to the desired position.
- Rotate the pin back to engage it into the adjustment hole and ensure it is fully seated.
- If clearance exists between the pin and housing, lubricate and re-seat the pin.
Maintenance:
