Wagner SprayTech 3000 - Manual (Page 12)

Pressure Relief Procedure
1. Keep the displacement pump packing nut/wet cup lubricated with Airlessco TSO (Throat Seal Oil) at all
times. The TSO helps protect the rod and the packings.
2. Inspect the packing nut daily. Your pump has a patented Triple Life Packing System. Packing life will be
extended a minimum of three times if the following "Packing Adjustment" procedure is followed:
If seepage of paint into the packing nut and/or movement of the piston upward is found
(while not spraying), the packing nut should be tightened enough to stop leakage only, but
not any tighter. Overtightening will damage the packings and reduce the packing life.
3. Tighten suction nut daily.
