3. Step 3: Connect Inner Loop. Reach behind the tire and connect the inner loop of the chain. Ensure it is securely fastened.
4. Step 4: Connect Outer Hooks and Tension. Connect the outer hooks, then engage the self-tensioning system by pulling the red chain through the tensioner and securing it. The chain will automatically adjust as you drive a short distance.

Operating Instructions

Once installed, follow these guidelines for safe operation:

• Speed Limit: Do not exceed 40 km/h (25 mph) when snow chains are installed.
• Driving Conditions: Use snow chains only on snow or ice-covered roads. Driving on bare pavement can damage the chains and your tires.
• Initial Drive: After installation, drive a short distance (approx. 100 meters) at a low speed (5-10 km/h) and then stop to check the chain tension. The self-tensioning system should have adjusted the chains. If necessary, re-tension manually.
• Smooth Driving: Avoid sudden acceleration, braking, or sharp turns to prevent chain damage and loss of control.
• Removal: Remove chains immediately when you reach clear pavement.

• Cleaning: After each use, clean the chains thoroughly with water to remove salt, dirt, and debris.
• Drying: Dry the chains completely before storing to prevent rust. Lay them flat or hang them in a dry, well-ventilated area.
• Inspection: Regularly inspect chains for any signs of wear, damage, or broken links. Replace damaged chains immediately.
• Storage: Store the chains in their original carrying case in a cool, dry place, away from direct sunlight and chemicals.

Troubleshooting

If you encounter issues with your snow chains, consider the following:

• Chains Feel Loose: Ensure the self-tensioning system is correctly engaged. Drive a short distance and re-check. If still loose, verify the chain size matches your tire.
• Unusual Noise/Vibration: Stop immediately and inspect the chains. This could indicate improper installation, a damaged link, or the chain rubbing against vehicle components.
• Difficulty Installing: Ensure the vehicle is on a flat surface and the chains are untangled. Practice installation in good conditions.
• Chain Breakage: If a chain breaks, remove it and the corresponding chain from the other drive wheel immediately to prevent vehicle damage. Do not continue driving with a broken chain.
