Note: This product is designed for vehicles that do not require bumper disassembly or cutting for installation.

5. Operating Instructions

Once the tow hitch is securely installed, follow these steps for safe towing:

1. Connect Trailer: Carefully back your vehicle towards the trailer. Lower the trailer coupler onto the ISO 50 ball head.
2. Secure Coupler: Engage the trailer coupler latch and ensure it is fully locked onto the ball. Check for proper engagement by attempting to lift the trailer tongue.
3. Attach Safety Chains: Cross the safety chains under the trailer tongue and attach them to the designated points on your vehicle's hitch receiver or frame. Ensure there is enough slack for turns but not so much that they drag on the ground.
4. Connect Electrical: Plug in the trailer's electrical connector to your vehicle's receptacle. Test all trailer lights (brake, turn signals, running lights).
5. Final Inspection: Before driving, perform a walk-around inspection to ensure all connections are secure, tires are properly inflated, and cargo is distributed evenly and secured in the trailer.

5.1. Height Adjustment

The ISO 50 ball head offers height adjustment. To adjust the height:

1. Remove the bolts securing the ball head assembly to the height-adjustable plate.
2. Move the ball head assembly to the desired height position, aligning the bolt holes.
3. Reinsert and securely tighten all bolts to the specified torque.
4. Ensure the trailer is level when connected to prevent uneven tire wear and improve towing stability.

6. Maintenance

Regular maintenance ensures the longevity and safe operation of your tow hitch device.

• Routine Inspection: Before each towing trip, inspect the tow hitch for any signs of cracks, bends, excessive rust, or loose fasteners.
• Cleaning: Clean the tow hitch regularly, especially after exposure to road salt, dirt, or harsh weather conditions. Use mild soap and water, then dry thoroughly.
• Lubrication: Apply a thin layer of grease to the tow ball to reduce friction and wear between the ball and the trailer coupler.
• Fastener Check: Periodically check and re-tighten all bolts and nuts to their specified torque values.
• Storage: If removing the hitch for storage, clean it thoroughly and store it in a dry place to prevent corrosion.

7. Troubleshooting

This section addresses common issues you might encounter with your tow hitch.

7.1. Common Issues and Solutions:

• Issue: Excessive play or rattling from the hitch receiver.
  Solution: Ensure the hitch pin is fully inserted and secured. Consider using an anti-rattle device if the play persists and is not due to loose components.
• Issue: Difficulty connecting the trailer coupler to the ball.
  Solution: Ensure the tow ball is clean and lightly greased. Verify the trailer coupler is fully open and aligned correctly. Check if the trailer tongue height is appropriate for the ball height.
• Issue: Visible rust or corrosion.
  Solution: Clean the affected area with a wire brush, apply a rust-inhibiting primer, and repaint with a suitable protective coating. If corrosion is severe and compromises structural integrity, replace the component.
• Issue: Trailer not towing level.
  Solution: Adjust the height of the ISO 50 ball head using the multiple bolt holes on the mounting plate. Ensure the trailer is as level as possible when connected.
