Newborn 930-GTD Drip-Free Smooth Hex Rod Cradle Caulking Gun
1. Setup and Cartridge Loading
Proper preparation of the caulk cartridge is crucial for effective application.
- Prepare Cartridge: Use the built-in spout cutter to cut the tip of the caulk cartridge at a 45-degree angle to the desired bead size.
- Puncture Seal: Use the built-in seal puncture tool (rod) to break the inner seal of the cartridge. Ensure the seal is fully punctured to allow caulk flow.
- Load Cartridge: Pull the plunger rod all the way back. Insert the caulk cartridge into the half-barrel frame, nozzle first. Push the plunger rod forward until it makes contact with the back of the cartridge.

2. Operating Instructions
- Dispensing: Squeeze the trigger repeatedly to dispense caulk. Apply steady pressure and move the gun along the seam at a consistent speed for an even bead.
- Drip-Free Feature: The smooth pressure rod automatically retracts after each trigger pull, relieving pressure on the cartridge to help prevent dripping.
- Comfort Grip: The padded handle and trigger are designed for comfort during extended use.
- Hanging Hook: Use the hook on the back of the gun to hang it on a ladder or other convenient location when not in immediate use.
3. Maintenance and Storage
- Cleaning: After use, remove the caulk cartridge. Clean any excess caulk from the gun frame and rod, especially if using water-based sealants. For cured caulk, gentle scraping may be required.
- Storage: Store the caulking gun in a clean, dry place. Ensure the plunger rod is fully retracted to relieve spring tension for long-term storage.
4. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No caulk dispenses | Inner seal not fully punctured; nozzle clogged; cartridge empty. | Ensure seal is fully punctured. Clear nozzle. Replace cartridge. |
| Caulk continues to drip | Plunger rod not fully retracting; material too thin. | Check for obstructions preventing rod retraction. Ensure proper material viscosity for the gun. |
| Difficult to dispense caulk | Material too thick; nozzle cut too small; old/hardened caulk. | Use appropriate caulk for 10:1 thrust ratio. Cut nozzle opening larger. Replace old caulk. |
