- Do not position any part of the 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 when operating the jack or coupling the trailer.
- Never exceed the maximum rated capacity. Refer to markings or decals on the product for rated capacity.
- Avoid excessive side forces, as they may lead to 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.
Tools Required:
- Torque wrench
- Ratchet set
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 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.
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 and secure the jack to the pivot tube with the supplied pin.
Drop Leg Operation:
Spring Return Drop Leg:
- Verify the jack is not supporting any load.
- Place your foot on the footplate to control the drop leg's return.
- Rotate the drop leg pin to disengage, then carefully move the leg to the desired position.
- Rotate the pin to engage it into the adjustment hole and ensure it is fully seated.
- Check for no clearance between the pin and housing. Lubricate if necessary. If the pin cannot be fully seated, do not use the jack.
Non-Spring Return Drop Leg:
- Verify the jack is not supporting any load.
- Grasp the handle of the footplate to control the descent of the drop leg.
- Rotate the drop leg pin to disengage, then move the leg to the desired position.
- Rotate the pin to engage it into the adjustment hole and ensure it is fully seated.
- Check for no clearance between the pin and housing. Lubricate if necessary. If the pin cannot be fully seated, do not use the jack.
Maintenance:
- Annually lubricate the gears, bushings, and screw of the jack with automotive grease.
- For side-wind models, use a grease gun at the lubrication points near the input shaft and rotate the handle to distribute the grease.
- Apply lightweight oil to the input shaft bushings and drop leg pin assembly.
- Keep the drop leg pin and spring clean and lubricated.
Safety Notes:
- Fully retract and rotate the jack before towing.
- Keep clear of pinch points during operation.

Installation Instructions for Powered Drive for Jacks
Tools Required:
- Welding equipment (performed by an AWS-certified welder)
- Standard tools for bolts, nuts, and wiring
Safety Instructions:
- Never position any part of the body under the jack or supported load.
- Fully retract and/or rotate the jack before towing.
- Ensure the drop leg pin is fully inserted before using the jack.

- Disconnect the battery ground cable before installation to prevent electrical shock.
- Replace bent, broken, or worn parts before use.
Installation Instructions:
Step 1: Remove the Jack Cross Shaft
- If the jack has non-welded hex bushings, consult the manufacturer's service bulletin for instructions.
- For planetary two-speed jacks, refer to the manufacturer's guidelines or specific service bulletins.
Step 2: Install the Powered Drive
- Temporarily replace the jack cross shaft with the powered drive/shaft assembly.
- Install the shaft on the non-geared side of the jack, ensuring the motor is facing downward and within the jack's profile.
Step 3: Position the Torque Stop Tube
- With the powered drive temporarily installed, use it to locate the torque stop tube on the jack's outer tube.
- Mark the location of the torque stop tube and weld it to the jack's outer tube using AWS-certified welding procedures.
Step 4: Final Assembly
- Reinstall the powered drive/shaft and place the energy-absorbing rubber bumper into the torque stop tube to prevent motor rotation.
- Attach the powered drive cover using 1/4” x 1” bolts and rubber-bonded washers. Torque bolts to 6 ft-lbs.
- Optionally, apply thread lock to the bolts.
Step 5: Tandem Jack Systems
- Use the included hex coupling to connect tandem jacks.
