Setup
Pressure-Feed Setup
- Prepare the Gun Body: Remove any protective foam from the needle of the spray gun.
- Attach Whip Hose Assembly: Remove the retention pin from the whip hose assembly. Slide the whip hose assembly bracket onto the air inlet of the gun. Replace the retention pin to secure it.
- Install Nozzle: Select the appropriate nozzle tip size for your application. While holding the trigger pulled, slide the nozzle firmly over the needle. Rotate the locking collar all the way around until it hits a stop. When correctly installed, the indicator will show an 'X' instead of a '+' sign.
- Connect Fluid Line: To attach your fluid connection, slide up on the connection and give it a quarter-turn rotation to lock it in place.
- Attach Air Gauge: Connect the air gauge to the appropriate port on the gun. Use a single wrench to tighten the top swivel, ensuring it is secure.
- Connect Hoses: Attach your fluid supply hose to the bottom of the whip hose. Connect your air line to the bottom of the air regulator gauge.
- Optional Shut-off Valve: If using the optional shut-off valve accessory, thread it onto the inlet of the hose whip, between your fluid supply and the bottom threads of the hose whip. This allows for quick shut-off to replace nozzles without depressurizing the entire bulk system.
Gravity-Feed Setup
The 3M Performance Spray Gun can also be configured for gravity-feed applications, ideal for quick touch-ups or smaller jobs.
- Remove Pressure Assembly: Detach the pressure assembly (whip hose, regulator, and pressure nozzle) from the gun body. If the pressure nozzle was just used, ensure you wipe the needle clean.
- Install Gravity Nozzle: Select a gravity feed nozzle and assemble it onto the gun body in the same manner as the pressure nozzle (sliding over the needle and locking the collar).
- Connect PPS Cup: Connect the 3M PPS Series 2.0 hard cup assembly (with appropriate lid and liner) to the top of the gun.
- The gun is now ready for gravity-feed applications, utilizing the same durable gun body.
