see figure 3-1, sheet 2. Remove leading edge backing strips as shown in figure 3-1, sheet 3. Apply first piece of tape to
area shown in figure 3-3. When the tape is in the proper position, press it on the blade as close to the leading edge as
possible. Press down on the tape, working toward the trailing edge to prevent trapping air bubbles. See figure 3-1, sheet

leading edge per figure 3-5 and mark where inboard edge mates with existing tape. Extend trim line on bottom side
straight back and mark inboard edge of tape per figure 3-5. Cut tape at the mark line. Apply No. 86 promoter and place
tape in position as shown in figure 3-5. Cut off tape extending past tip of blade. Any bubbles encountered during the
application process may be removed by continuous squeegee stroking towards the edge of the tape or by puncturing the
bubbles with a needle and applying pressure to the wet adhesive.
