3. Setup and Assembly
3.1 Battery Installation and Charging
The Seesii CG120P is compatible with Ma-kita 18V batteries (BL1830, BL1840, BL1850, BL1860).
- Ensure the battery is fully charged before use. A full charge takes approximately 2 hours.
- To install the battery, align the battery pack with the receptacle on the tool handle and slide it in until it clicks into place.
- To remove the battery, press the release button on the battery pack and slide it out.
3.2 Loading a Sealant Cartridge
The caulking gun is designed for 10oz/300ml sealant cartridges.
- Cut the tip of the sealant cartridge at the desired bead size using a utility knife.
- Pierce the inner seal of the cartridge using a long, thin object (e.g., a nail or the piercing tool often included with sealant).
- Pull back the plunger rod of the caulking gun completely.
- Insert the sealant cartridge into the gun's holder, ensuring the nozzle faces forward.
- Push the plunger rod forward until it makes contact with the back of the cartridge.
4. Operating Instructions
4.1 Speed Adjustment
The caulking gun features 4 adjustable speed settings, allowing for precise control of the sealant flow from 0 to 220 MM/Min.
- Use the speed selector switch (usually a dial or buttons) to choose the desired flow rate.
- Start with a lower speed for delicate work or when you are new to the tool, and increase as needed.
4.2 Applying Sealant
- Hold the gun firmly with both hands, if necessary, to maintain control.
- Position the nozzle at the starting point of your application area.
- Press the trigger to begin dispensing sealant. Move the gun steadily along the seam or gap.
- Release the trigger to stop the flow. The automatic anti-drip design will retract the plunger by 3mm to prevent excess material from dripping.
4.3 Using the LED Work Light
The built-in super bright LED light helps illuminate your work area, especially in dimly lit spaces.
- The LED light activates automatically when the trigger is pressed, providing clear visibility for precise application.
4.4 360° Rotating Holder
The cartridge holder can rotate 360 degrees, offering maximum flexibility and comfort for various application angles.
- Adjust the orientation of the cartridge as needed by rotating the holder to achieve optimal working position.
5. Maintenance
5.1 Cleaning
- After each use, remove the sealant cartridge and clean any excess sealant from the nozzle, plunger rod, and holder.
- Use a damp cloth to wipe down the exterior of the tool. Avoid using harsh chemicals or abrasive cleaners.
- Ensure the tool is dry before storing.
5.2 Storage
- Store the caulking gun and batteries in a cool, dry place, away from direct sunlight and moisture.
- Remove the battery from the tool if it will not be used for an extended period.
6. Troubleshooting
- Tool not operating: Check if the battery is properly installed and charged. Ensure the power switch is in the 'ON' position.
- Sealant not dispensing: Verify that the cartridge tip is cut and the inner seal is pierced. Check if the plunger rod is fully engaged with the cartridge. Ensure the cartridge is not empty or clogged.
- Uneven sealant flow: Adjust the speed setting to a lower rate. Ensure the nozzle is clean and not partially blocked.
- Excessive dripping: The anti-drip feature should minimize this. Ensure the trigger is fully released. If dripping persists, check for any sealant residue around the plunger mechanism.
