Introduction
Thank you for choosing the SEEKONE NL-233 Dual Power Hot Glue Gun. This manual provides essential information for the safe and effective operation, maintenance, and troubleshooting of your new tool. Please read these instructions carefully before use and retain them for future reference.
Important Safety Instructions
Failure to follow these safety instructions may result in electric shock, fire, or serious injury.
- Always wear appropriate safety glasses to protect your eyes from hot glue splashes.
- Do not touch the nozzle or melted glue directly. The operating temperature can reach up to 428°F (220°C) and can cause severe burns.
- Ensure the glue gun is placed on its stand when not in use to prevent hot glue from dripping onto surfaces or causing burns.
- Keep the glue gun out of reach of children and pets.
- Do not use the glue gun in damp or wet conditions, or near flammable materials.
- Never pull the power cord to disconnect the plug from the outlet. Grasp the plug firmly.
- Unplug the glue gun when not in use, before cleaning, or when changing glue sticks.
- Do not attempt to disassemble or modify the glue gun. Refer all servicing to qualified personnel.
- Use only 11mm diameter glue sticks with this device.

Setup Instructions
Follow these steps to prepare your glue gun for use:
- Insert Glue Stick: Insert an 11mm diameter glue stick into the hole at the back of the glue gun. Push it gently until it stops.
- Power On: Plug the power cord into a standard 110V AC electrical outlet. The power indicator light will illuminate.
- Select Power Mode: Use the switch on the side of the glue gun to select your desired power mode: switch to the left for 60W (low temperature) or to the right for 100W (high temperature).
- Preheat: Allow the glue gun to preheat for 3-5 minutes. The glue will melt and be ready for use.

Operating Instructions
Once preheated, gently squeeze the trigger to dispense melted glue. Apply glue to the desired surface. The glue will bond quickly and cool rapidly.
- 60W Mode: Ideal for delicate materials, small crafts, and applications where lower heat and slower setting time are preferred. Temperature: 284°F (140°C).
- 100W Mode: Suitable for larger projects, heavy-duty bonding, and materials that require higher heat for optimal adhesion. Temperature: 428°F (220°C).
- When a glue stick is nearly depleted, insert a new one into the back to push the remaining stick through.
- Always place the glue gun on its metal stand when not actively applying glue to prevent dripping and ensure stability.

Maintenance
- Cleaning the Nozzle: After use, and once the glue gun has cooled completely, gently wipe any excess glue from the nozzle with a dry cloth. Do not use water or solvents.
- Storage: Store the glue gun in a dry, clean place, away from direct sunlight and extreme temperatures. Ensure it is unplugged and completely cool before storing.
- Nozzle Replacement: The nozzle is replaceable. If replacement is needed, ensure the gun is unplugged and cool. Carefully unscrew the old nozzle and screw on a compatible 10.8mm replacement.
Troubleshooting
If you encounter issues with your glue gun, refer to the following table:
| Problem | Possible Cause | Solution |
|---|---|---|
| Glue gun does not heat up. | Not plugged in; power outlet malfunction; internal fault. | Check power connection. Test outlet with another device. If still not working, contact customer support. |
| Glue does not flow or flows slowly. | Insufficient preheating time; glue stick not fully inserted; wrong power mode for application; nozzle clogged. | Allow full preheating time (3-5 min). Push glue stick firmly. Switch to 100W for faster flow. Ensure nozzle is clear (only when cool). |
| Excessive dripping from nozzle. | Gun left on for too long; incorrect glue stick size; internal issue. | Unplug when not in use. Ensure 11mm glue sticks are used. If problem persists, contact customer support. |
| Glue gun feels too hot to handle. | Normal operation at 100W; prolonged use. | Use caution. The body may become warm. If it feels excessively hot or emits smoke, unplug immediately and contact support. |
