Frequently Asked Questions - InvisiPac PC-8e GRACO

How do I prime the pump before spraying?

Turn the pressure control to low, open the prime valve, and run the motor until paint flows steadily. Then close the prime valve and increase pressure.

What is the maximum recommended paint viscosity?

The sprayer can handle paints up to 70 KU (Krebs Units). Thicker paints may need thinning.

How do I clean the sprayer after use?

Flush with water for latex paints or mineral spirits for oil-based paints. Run clean fluid through the system until clear.

Why is the motor running but no paint coming out?

Check if the prime valve is open, the tip is not clogged, or the suction tube is not submerged. Also ensure the pressure is set high enough.

Can I use the sprayer with exterior paints?

Yes, the sprayer is suitable for both interior and exterior paints, including latex and oil-based.

How often should I replace the filter?

Replace the inlet filter after every 50 gallons of paint or sooner if clogging occurs. The gun filter should be cleaned regularly.

What should I do if the spray pattern is uneven?

Adjust the pressure, clean the tip, or replace the tip if worn. Also ensure paint is properly mixed and viscosity is correct.

Is it safe to use extension cords?

Use a heavy-duty extension cord rated for at least 15 amps and no longer than 100 ft. Avoid using multiple cords.

How do I store the sprayer for long periods?

Thoroughly clean the system, drain all fluids, and store in a dry, frost-free area. Apply a light oil to moving parts.

What is the warranty period and how to claim?

Graco offers a 1-year limited warranty. Contact Graco customer service with proof of purchase for repairs or replacement.
