- Do not place any part of your body under the jack or the load being supported.
- Fully retract and/or rotate the jack before towing.
- Verify the drop leg pin is fully inserted before using the jack.
- Block wheels to prevent rolling during operation.
- Never exceed the maximum rated capacity as marked on the product.
- Avoid excessive side forces to prevent jack failure.
- Replace any bent, broken, or worn parts before use.
- Use only on flat surfaces. For tandem applications, align jacks to share the load equally.

Step-by-Step Instructions:
Direct Mount to Load-Bearing Member:

- Apply three 2-inch-long 1/4” fillet welds on both sides of the jack along the contacting surface. Space welds as far apart as possible for maximum load strength.
- For tandem applications, align jacks carefully to ensure they raise and lower together, sharing the load equally.
Weld-On Pivot Tube Mounting:
