1. Follow the Pressure Relief Procedure on page 20.
2. Turn off the main air valve.
3. Remove the screws (469) and the two guards
(424, 446) from the sides of the proportioner. See
Fig. 98.
4. The wet cups should be 1/3 full of Graco Throat
Seal Liquid (TSL) or compatible solvent.
5. The packing nuts are torqued at the factory and
are ready for operation. Check the tightness of the
packing nut weekly. If it becomes loose and there
is leaking from the throat packings:
a. Follow the Pressure Relief Procedure, page
20, before adjusting the packing nut.
b. Tighten the packing nut to the torque for your
lower model, using the wrench supplied. See
the table below. Do not over-tighten the pack-
ing nut. Too tight an adjustment causes the
packings to bind or wear prematurely and leak.
