Airless Paint Systems

Maintenance (Cont.)

Inspect the packing nut daily. 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.

4.Lubricate connecting rod pin every 3 months.

Utilizing packing removal tool (187-249) the complete packing set can be removed quickly and easily. Another method is to wrap some masking tape around the bottom of the piston. Now push the piston back through the pump and remove through the top. The packings and glands will be removed with the piston rod, leaving the fluid body empty.
