1. Find puncture site by listening for leaking air, bubble testing or locating the puncture object. 2. Roll plug firmly between fingers to reduce
diameter and straighten if needed. It is
helpful to dip or wet the plug in water before
rolling to make it less sticky. This acts as a
lubricant for easier insertion in the tube of
the tool. The stickiness returns when the
water evaporates.
3. Load plug into tool until brass tip seats against end of tube.
Note: If the insertion tube become clogged, clean with a Dynaplug® TUBE CLEANER dipped in denatured alcohol, available at your local paint or hardware store. NEVER USE SOLVENTS on the tool.
4. With pliers (when available), remove puncture object and note the direction of the puncture.
5. Align tool with angle of puncture hole and push straight through the hole. Once started, do not stop until handle hits the tire.
6. Pull tool from hole. Plug will remain in hole. For most punctures from nails and screws, one plug is sufficient. Check for air leaks. If air leaks after the first plug is retained, insert a second plug. Bend the tail of the first plug over against the tire and hold while inserting another plug beside the first plug. Repeat up to four times if air continues to leak. Never attempt to repair a hole that is larger in diameter than the Dynaplug® tool tube. 7. If any air is lost during the repair, inflate tire to manufacturers reccommended specifications. Clip end of plug/s flush with tire using the cutter on pliers or a knife

8. After each use, unscrew the tool end cap and hold tool up to the light and sight through stainless tube. If any rubber elastomer is seen on the tube walls, clean with Dynaplug® TUBE CLEANER and denatured alcohol.

Never attempt to repair a hole that is larger in diameter than the Dynaplug® tool tube.
