How to Repair a Tire with Maruni MR Insert and STEM Plug

Use pliers to remove foreign objects from the hole in the tire and mark the damaged area with chalk.	Drill the damage area several times with a reamer from both the outside and inside of the tire	Insert the plug through the insert tool (for new-type plugs, this step is unnecessary, as they are equipped with wire).
Remove the protective film from the STEM plug and apply MARUNI Super Valkarn vulcanizing fluid.	Apply a small amount of Super Valkarn fluid to the damage channel.	If using a plug without a guiding wire, use the plug insertion tool.
Pull the plug through, pulling the pliers from the outside of the tire. A portion of the plug should extend from the inside of the tire.	Cut the plug end on the inside of the tire 2-3 mm from its surface.	Place the patch on the tire and mark the area slightly larger than the patch using chalk. Pay attention to the correct direction of insert placement – arrows should point to the tire bead.
On the marked area, apply Liquid Buffer to clean and chemically roughen the tire. Remove dirt and grease with a scraper.
