4. Setup and Installation

Follow these steps to properly install the ARK XO750 Trailer Jack onto your trailer:

1. Positioning: Select a suitable mounting location on your trailer frame. The square body and swivel clamp design allow for versatile placement. Ensure the jack will not interfere with other trailer components or vehicle movement.
2. Mounting the Swivel Clamp: Attach the heavy-duty swivel clamp to the trailer frame using appropriate bolts, washers, and nuts (not included, typically supplied with trailer). Ensure the clamp is tightened securely to prevent movement during operation. The clamp should be positioned to allow the jack to swivel freely when needed.
3. Attaching the Jack: Insert the upper tube of the jack into the swivel clamp. Secure it in place using the provided pin or locking mechanism. Ensure the jack is fully seated and the pin is engaged.
4. Handle Attachment: The magnetic removable side-winding handle can be attached to the side-winding mechanism. Ensure it is firmly in place before operation. The magnetic feature allows for easy removal and storage when not in use.
5. Yoke Adjustment: The jack features a variable yoke lock and an easy-pivot trailing yoke design. Adjust the yoke to the desired position for optimal trailer support and maneuverability. Ensure the yoke is locked before applying load.

5. Operating Instructions

To raise or lower your trailer using the ARK XO750 Trailer Jack:

1. Preparation: Ensure the trailer is on a firm, level surface. Chock the trailer wheels to prevent accidental movement.
2. Positioning the Jack: If the jack is in the stowed (horizontal) position, release the swivel clamp pin and rotate the jack to the vertical operating position. Re-engage the pin to lock it.
3. Raising the Trailer: Attach the magnetic side-winding handle. Turn the handle clockwise to extend the jack and raise the trailer. Continue turning until the desired height is reached, up to a maximum of 28 inches. Do not over-extend the jack.
4. Lowering the Trailer: Turn the handle counter-clockwise to retract the jack and lower the trailer. Lower slowly and in a controlled manner.
5. Stowing the Jack: Once the trailer is hitched or supported, release the swivel clamp pin, rotate the jack to its horizontal stowed position, and re-engage the pin. Remove the magnetic handle for storage.

The jack offers four height positions for versatility. Always ensure the jack is stable and the load is centered before and during operation.

6. Maintenance

Regular maintenance ensures the longevity and safe operation of your ARK XO750 Trailer Jack:

• Cleaning: Keep the jack clean and free from dirt, mud, and debris. Wipe down the outer surfaces regularly.
• Lubrication: Periodically apply a light coat of grease or lubricant to the screw mechanism and moving parts to ensure smooth operation. Do not over-lubricate.
• Inspection: Before each use, inspect the jack for any signs of damage, cracks, bends, or excessive wear. Check all pins, bolts, and the swivel clamp for tightness and integrity.
