5. Setup: Loading the Puncture Repair Gun

Before performing a repair, the mushroom plug must be correctly loaded into the repair gun.

1. Hold the Gun: Hold the threaded end of the gun firmly upright.
2. Insert the Plug: Set the mushroom plug into the gun with the stem facing down and the mushroom head facing up.
3. Recess the Mushroom Head: Use the tip of the nozzle (or the provided insertion tool) to gently push the mushroom head down into the gun until it is fully recessed.
4. Push Plug Completely: Ensure the plug is pushed completely inside the gun, with the mushroom head fully seated.

6. Operating Instructions: Performing a Tire Repair

Follow these steps to repair a tubeless tire puncture using your GRAND PITSTOP kit. Remember to observe all safety warnings.

1. Locate the Puncture: Identify the exact location of the puncture. If necessary, inflate the tire and listen for air leaks or apply soapy water to the tire surface to find bubbles.
2. Remove Object: Carefully remove the object that caused the puncture (e.g., nail, screw) using pliers if needed.
3. Prepare the Hole: Use the provided reamer/probe tool to clean and enlarge the puncture hole. Insert and twist the reamer tool several times to ensure the hole is ready for the plug. This helps the plug seat properly.
4. Load the Gun: Follow the "Setup" instructions (Section 5) to load a mushroom plug into the repair gun.
5. Insert the Plug: Position the nozzle of the loaded gun directly over the prepared puncture hole. Press the gun firmly and quickly into the tire until the plug is fully inserted. You may hear a slight pop as the mushroom head expands inside the tire.
6. Remove the Gun: Once the plug is inserted, pull the gun straight out of the tire. The mushroom plug should remain in place, sealing the puncture.
7. Trim Excess: Use the trimming knife to carefully cut off any excess plug material protruding from the tire's exterior, leaving it flush with the tire surface.
8. Inflate and Check: Inflate the tire to the recommended pressure. Apply soapy water around the repaired area to check for any remaining air leaks. If no bubbles appear, the repair is successful.

7. Maintenance

Proper maintenance ensures the longevity and effectiveness of your repair kit.

• Plug Storage: Always store unused mushroom plugs in a sealed zip-lock bag to keep them lubricated and prevent them from drying out.
• Tool Cleaning: After each use, clean the repair gun and other tools to remove any dirt or debris. Wipe them dry before storing.
• Storage: Store the entire kit in its carrying pouch in a cool, dry place, away from direct sunlight and extreme temperatures.

8. Troubleshooting

If you encounter issues during the repair process, consider the following:

• Plug Not Sealing:
  • Ensure the puncture hole was adequately reamed and cleaned.
  • Verify the plug was fully inserted and the mushroom head expanded inside the tire.
  • Check if the puncture size exceeds the recommended 5/16th inch (7mm) limit.
  • Ensure plugs are not dried out; store them in a sealed bag.
• Difficulty Inserting Plug:
  • Confirm the plug is correctly loaded into the gun as per Section 5.
  • Ensure the puncture hole is sufficiently enlarged by the reamer tool.
• Air Leak Persists:
  • Re-check the repaired area with soapy water for small leaks.
  • Inspect the entire tire for additional punctures.
  • If the leak persists, the puncture may be too large or in a location unsuitable for this type of repair. Seek professional tire service.
