1. REPAIR PROCEDURES FOR COMBINATION REPAIR UNITS

Before repairing, mark and remove puncturing object. With tyre inflated, apply soap solution to damaged area to determine if air loss is from one or more punctures. Remove tyre from wheel carefully to avoid further damage and place on spreader.

2. PROBING

Probe puncture to determine size and direction of injury, making sure to remove all foreign materials. DO NOT repair it when injury is beyond puncture repair limits.

3. INTERNAL EXAMINATION

Spread the beads and mark the damaged area with a crayon. Carefully inspect tyre to ensure that all damage is within repairable limits. If limits are exceeded, DO NOT repair the tyre.

4. REPAIR UNIT SELECTION

If injury is 1/4''(6mm) or smaller in diamater and angle does not exceed 25Y, a combination repair unit is the easiest method of repair. Reinforced Combination Units are for tread area only Universal and Lead-Wire Combination Units may be used in any repairable area.

5. CLEANING

Using buffing solution and an inner scraper, clean thoroughly an area slightly larger than the patch head of the repair unit. This serves to remove dirt and mold lubricants for better adhesion.

6. BUFFING

Using a buffing wheel, buff repair area to texture taking care not to gouge the inner liner. Using appropriate reamer of cutter(for lead-wire units), drill injury channel from inside and from outside, removing damaged cables and debris. Vacuum away buffing dust.

7. CEMENTING

Apply vulcanizing cement to the injury channel and prepared repair area. Work cement into the rubber. DO NOT puddle or scrape pff. ALLOW CEMENT TO DRY THOROUGHLY.

8. INSERTION

Remove backing from patch head(and stem fo Lead-Wire Units) DO NOT touch gum surface. Push quill or lead wire into the injury from inside and pull through with pliers. Pull until patch head is seated firmly against the inner liner.

9. FINISH REPAIR

Thoroughly stitch the patch bead to the inner liner working from the center outward to remove any trapped air. Cut the stem 1/8'' above tread surface. Apply Inner Liner Sealer to overbuffing area and allow to dr
