How do I set up and use the Graco 390 for the first time?

Setting up and using the Graco 390 for the first time is straightforward:

  1. Assembly: Begin by assembling the sprayer as per the user manual. Attach the hose, gun, and tip.
  2. Prime the Pump: Fill your paint bucket. Place the suction tube into the paint and the drain tube into a waste container. Turn the prime/spray valve to “prime” and start the sprayer. Once paint flows out without air bubbles, it’s primed.
  3. Spray Mode: Turn the prime/spray valve to “spray”. Hold the gun over the waste container and pull the trigger until paint sprays out.
  4. Adjust Pressure: Start with low pressure and gradually increase until you get a smooth spray pattern.
  5. Spraying: Hold the gun about 12 inches from the surface and move steadily. Overlap each pass by about 50% for even coverage.
  6. Cleanup: After use, clean the sprayer thoroughly. Run water or solvent (based on paint type) through the system until it’s clear.

How energy-efficient is the Graco 390, and what’s its power consumption?

The Graco 390 is designed with efficiency in mind, catering to both professionals and DIY enthusiasts. Its motor is rated at 5/8 horsepower, which, while powerful enough to handle most painting tasks, doesn’t consume excessive electricity.

On average, it operates at around 120 volts and draws approximately 7-8 amps. One of the lesser-known features contributing to its energy efficiency is its on-demand piston pump operation. Instead of continuously running, the pump only operates when a specific pressure drop is detected, conserving energy.

Additionally, the Graco 390’s SmartControl 1.0 system ensures consistent pressure without frequent pump cycling, further optimizing power usage. This combination of features ensures that the Graco 390 provides optimal performance without excessive energy consumption.
