(8) Inspect boot interior for any shiny areas. Sand these shiny areas again and wipe clean.
d. Vacuum Set Up. Wrap sufficient strip(s) of sealant tape around the blade chordwise to ensure a good seal for the
vacuum bag. Make sure that 4 inches of excess sealant is left hanging off the leading and trailing edges. Leave the
adhesive backing strip on the outside of the sealant tape until vacuum bag application. Apply sealant tape around the
vacuum hose manifold per the applicable illustration in figures 5-3 and 5-5. Ensure "T" fittings are positioned on the
masking tape surrounding the bond area. Tape hose into position with masking tape. Connect vacuum lines to the pump
and manifolds. Check pump for operation.
NOTE
If more than one tip cap boot is being installed, disconnect vacuum lines leading to
all additional tip caps. The only vacuum line connected should only be on the first
tip cap to be worked on. Seal off the end of the additional vacuum lines with
pieces of sealant tape.
The disconnected tip cap vacuum lines may be
reconnected as their respective tip cap boots are being installed.
