TOPCOAT GUN SETTINGS
When spraying Topcoat 311 with the Central Pneumatic 20 oz. HVLP spray gun, we recommend the settings shown below. Most HVLP spray guns allow for these same adjustments. If you are using a different spray gun, follow the manufacturer’s instructions.

② Fan Pattern
The fan pattern should be set 1/2 turn out from the most narrow fan pattern, or “pencil”.
- First, rotate the fan pattern knob fully clockwise; then rotate the knob counter-clockwise 1/2 turn. The indicator mark on the knob should be 180° from the starting position.
③ Fluid Control
The fluid control should be set at 1 1/4 turns out from complete shutoff.
- Rotate the fluid control knob fully clockwise; then rotate the knob 1 1/4 turns counter-clockwise. Use the indicator mark on the knob to help determine the amount of rotation.
④ Air Control (Internal)
The internal air control should be all the way open.
- Rotate the air control knob fully counter-clockwise. This knob is always set to the fully open position.
⑤ Pressure Gauge
⑥ Air Control (External)
The air control valve is attached to the bottom of the spray gun, and controls the precise incoming air pressure. It should be set to 22-25 PSI.
- Squeeze the gun trigger down half way; so that compressed air is emitted, but no paint. While holding the trigger, adjust the external air control knob until the pressure gauge reads 22-25 PSI.
