2. Safety Information

Always prioritize safety when working with spray equipment and materials. Failure to follow safety precautions can result in injury or property damage.

• Read and understand the instructions for your spray gun and the material being sprayed before use.
• Wear appropriate personal protective equipment (PPE), including respirators, safety glasses, and gloves.
• Ensure adequate ventilation in your work area to prevent inhalation of fumes.
• Keep the cup and its contents away from open flames, sparks, and heat sources.
• Dispose of waste materials and cleaning solvents according to local environmental regulations.

3. Components

The DeVilbiss GFC501 Gravity Feed Cup consists of the following primary components:

• Gravity Feed Cup Body: A translucent acetal container designed to hold sprayable material.
• Lid: A white plastic lid that seals the cup, often featuring a vent to allow for proper material flow.
• Fluid Connector: A threaded metal fitting at the bottom of the cup for attachment to a spray gun.

4. Setup

Follow these steps to prepare your DeVilbiss GFC501 Gravity Feed Cup for use:

1. Inspect Components: Before each use, inspect the cup body, lid, and fluid connector for any signs of damage, cracks, or wear. Ensure all parts are clean and free of debris.
2. Attach to Spray Gun: Carefully thread the fluid connector of the gravity feed cup onto the material inlet of your compatible gravity feed spray gun. Hand-tighten until secure. Do not overtighten, as this can damage the threads.
3. Check for Stability: Ensure the cup is firmly attached to the spray gun and does not wobble. A secure connection prevents leaks and ensures consistent material flow.

5. Operating Instructions

Proper operation of the gravity feed cup involves careful filling and sealing:

1. Prepare Material: Mix and filter your paint or sprayable material according to the material manufacturer's instructions.
2. Fill the Cup: Pour the prepared material into the DeVilbiss GFC501 cup. Do not fill beyond the recommended capacity or to the very brim, to prevent spills and allow for proper lid sealing.
3. Secure the Lid: Place the lid onto the cup and twist or press firmly to create a secure seal. Ensure the vent hole (if present) is clear and functioning correctly to allow for proper air equalization as material is drawn from the cup.
4. Begin Spraying: Refer to your spray gun's instruction manual for specific operating procedures, including air pressure settings, spray patterns, and application techniques.

6. Maintenance and Cleaning

Regular cleaning and maintenance are essential for the longevity and performance of your gravity feed cup. This product is designed for hand washing only.

Cleaning Procedure:

1. Empty Remaining Material: After use, empty any remaining material from the cup into an appropriate waste container.
2. Disassemble: Detach the cup from the spray gun and remove the lid.
3. Hand Wash Only: Wash the cup body and lid thoroughly by hand using a compatible cleaning solvent or warm soapy water. Use a brush to remove any dried material from inside the cup and around the threads.
4. Rinse: Rinse all components with clean water to remove any cleaning solution residue.
5. Dry: Allow all parts to air dry completely before reassembly or storage. Ensure no moisture remains, especially if storing for extended periods.

Important: Do not use abrasive cleaners or tools that could scratch or damage the cup's surface. Avoid exposing the cup to harsh chemicals that are not compatible with acetal plastic.
