Setup

c. Don't use thread sealant on the swiveling nut
of the hose couplings, and don't install the
spray tip yet.
NOTE: Use thread sealant on all male threads except at
swivel unions. Swivel unions are made to self–
seal, and using thread sealant prevents the
swivel from turning freely.
2. Fill the Packing Nut/Wet Cup 1/3 full with Graco
Throat Seal Liquid (TSL), supplied. See Fig. 2.
