Installation Instructions for 12,000 lb Square Tube Jack
General Installation Notes:
- Follow these instructions carefully without alterations.
- Never position any part of your 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 operating the jack.
- Block wheels to prevent rolling during jack operation or trailer coupling.
- Never exceed the maximum rated capacity as marked on the product.
- Avoid excessive side forces to prevent 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.
- Check for interference during all stages, including handle swing and swivel positions.
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 strength.
- For tandem applications, align the jacks to 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 it and carefully 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 handle 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 drop leg's descent.
- Rotate the drop leg pin to disengage it 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 handle and housing, lubricate and re-seat the pin.
Maintenance:
- Annually lubricate the gears, bushings, and screws with automotive EP2 grease.
- For side-wind models, use a grease gun at lubrication points near the input shaft.
- Apply lightweight oil to the input shaft bushings and drop leg pin assembly.
- Keep all components clean and lubricated regularly.
Safety Notes:
- Fully retract and rotate the jack before towing.
- Keep clear of pinch points during operation.
- Never adjust the drop leg while the jack is under load.
