2. Inspect the packing nut daily. Your pump has Airlessco’s 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. Check suction nut daily.
