Step 9 - CAUTION: Do not overheat the cable. Prolonged exposure of the jacket to temperatures above l60oC (320oF) may damage the cable jacket. Discontinue heating of the sleeve and allow the cable jacket to cool before reheating if the cable jacket shows any signs of bubbling.

Center the sleeve over the damaged area and, holding the heat gun approximately l00 mm (4 in) away, heat evenly from the center to the ends around the entire sleeve until the sleeve changes color indicating a full recovery (see figure lBl-6). Melted sealant should be visible at the end of sleeve.
