REGULAR MAINTENANCE

1. Always stop the pump at the bottom of its stroke when you take
a break or at the end of the day. This helps keep material from
drying on the rod, dam ag ing the packings.
2. Keep the displacement pump packing nut/wet cup 1/3 full of
Airlessco Throat Seal Oil at all times. The TSO helps protect the
packings and rod.
3. Lubricate Connecting Rod Pin every 3 months.
4. Inspect the packing nut daily. Your paint pump has
Airlessco's patented "Triple Life Packing System".
Packing life will be extended a minimum of
3 times if the proper packing tightening
pro ce dure is followed!
