1. Prepare the Cartridge: Using a utility knife, carefully cut the tip of the caulk nozzle at a 45-degree angle to the desired bead size (minimum diameter of 4mm).
2. Pierce the Inner Seal: Insert the included piercing tool or a long nail through the cut nozzle to break the inner foil seal of the caulk cartridge. This is crucial for proper material flow.
3. Load the Cartridge: Pull the plunger rod of the caulk gun fully back. Insert the prepared caulk cartridge into the barrel of the gun, nozzle first.
4. Engage the Plunger: Push the plunger rod forward until it makes contact with the back of the caulk cartridge.

6. Operating Instructions

Once the caulk gun is set up, follow these steps for effective operation:

6.1. Powering On and Adjusting Speed

1. Ensure the battery is securely installed.
2. The caulk gun features a speed adjustment dial, typically located near the handle. Rotate the dial to select your desired speed setting (1-4). For beginners or delicate work, start with the lowest speed (Gear 1). For faster application or thicker materials, increase the speed.

6.2. Applying Caulk

1. Position the nozzle at the starting point of your application area, maintaining a consistent angle.
2. Press the trigger to begin dispensing caulk. Move the gun steadily along the seam or gap you are sealing.
3. Release the trigger to stop the flow of caulk. The auto-retract mechanism will pull the plunger back slightly to prevent dripping.
4. Use the included caulk remover tool and silicone pads to smooth the caulk bead as needed.

6.3. Using the LED Light

The built-in LED light activates automatically when the trigger is pressed, illuminating your work surface for improved visibility in low-light conditions.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your caulk gun.

7.1. Cleaning the Caulk Gun

• After each use, especially if using quick-drying materials, remove the caulk cartridge.
• Wipe down the barrel and nozzle area with a damp cloth to remove any excess caulk. For dried caulk, use a suitable solvent recommended by the caulk manufacturer, ensuring it does not damage the gun's plastic components.
• Keep the plunger rod clean and free of debris to ensure smooth operation.

7.2. Battery Care and Storage
