Operating Instructions
Follow these steps to safely operate your TYT trailer jack:
- Prepare the Trailer: Ensure the trailer is on a stable, level surface and the wheels are properly chocked to prevent movement.
- Adjust Drop Leg (if necessary): If the trailer tongue is too high or low for the jack to reach the ground, remove the retaining pin from the drop leg. Adjust the drop leg to the appropriate height, then re-insert the pin and secure the clip.
- Lowering the Trailer: Turn the sidewind handle counter-clockwise to extend the jack and lower the trailer tongue.
- Lifting the Trailer: Turn the sidewind handle clockwise to retract the jack and lift the trailer tongue.
- Final Positioning: Once the desired height is achieved, ensure the jack is stable before performing any work on the trailer or hitching/unhitching.
Maintenance
Regular maintenance will extend the life and ensure the safe operation of your trailer jack.
- Lubrication: Periodically lubricate the internal screw mechanism through the built-in oil port. Use a high-quality grease or lubricant suitable for trailer jacks.
- Cleaning: Keep the jack clean from dirt, mud, and road debris. Wipe down the outer and inner tubes regularly.
- Corrosion Inspection: Despite its corrosion-resistant coating, regularly inspect the jack for any signs of rust or damage, especially in areas exposed to harsh weather or road salt. Address any corrosion promptly.
- Hardware Check: Ensure all pins and clips are secure and in good condition. Replace any worn or damaged components immediately.
Troubleshooting
If you encounter issues with your TYT trailer jack, consider the following common solutions:
- Difficulty Cranking:
- Check for obstructions around the handle or screw mechanism.
