Check the spray pattern. The tip size and angle determines the pattern width and flow rate. WARNING Be sure to relieve pressure in the pump after filling with Airlessco Pump Conditioner. WARNING 5. When Shutting off the Sprayer Follow the "Pressure Relief Procedure".
Service Center. DAILY MAINTENANCE 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"...
SPRAY GUN OPERATION SPRAY GUN Attach spray gun to airless unit and tighten fit- tings securely. Set the gun safety latch. (Also may be called gun safety lock, or trigger lock) * The gun safety latch should always be set when the gun is not being triggered.
TIP SELECTION GUIDE Spray tip selection is based on paint viscosity, Spray tip size is based on how many gallons of paint paint type, & job needs. For light viscosities (thin per minute can be sprayed through the tip. Do not use paints), use a smaller tip;...
REGULAR MAINTENANCE 1. Always stop the pump at the bottom of its' stroke when you take a break at the end of the day. This helps keep material from drying on the rod and damaging the packings. 2. Keep the displacement pump packing nut/wet with five drops of TSO at all times. The TSO helps protect the packings and rod.
