Setup
1. Charging the Glue Gun
Before first use, ensure the glue gun is fully charged. The battery indicator lights will show the charging status.
- Connect the charger to the USB charging port located at the rear of the glue gun.
- Plug the charger into a standard wall outlet.
- The battery indicator light will be red while charging and turn green when fully charged. A full charge takes approximately 3.5 hours.
- Once fully charged, disconnect the charger before use.

2. Inserting a Glue Stick
- Ensure the glue gun is turned off and cool.
- Insert a premium mini hot melt glue stick into the circular opening at the back of the glue gun until it stops.
Operating Instructions
1. Turning On and Preheating
- Press and hold the power switch (ON/OFF button) for approximately 3 seconds to turn on the glue gun.
- The working status indicator light will illuminate.
- Allow the glue gun to preheat for about 2 minutes. The advanced PTC heating system ensures rapid heating.
- Once preheated, the working status indicator will change to indicate readiness (e.g., solid green).

2. Applying Glue
- Once the glue gun is preheated, gently press the trigger to dispense melted glue.
- The glue gun features a drip-free nozzle to minimize mess during use.
- The WORKPRO glue gun offers a fast dispensing speed of 0.18 oz/5 g per minute.

3. Automatic Power-Off Protection
The smart linkage switch automatically cuts off power after 8 minutes of inactivity. This feature protects the user and conserves energy.
4. Using the Integrated Stand
The glue gun includes a small bracket near the nozzle. This bracket can be folded down to act as a stand, allowing you to safely rest the hot glue gun on a surface without the hot nozzle touching it, preventing drips and potential damage.

5. Turning Off
To manually turn off the glue gun, press and hold the power switch for approximately 3 seconds. The automatic power-off feature will also activate after 8 minutes of inactivity.
Maintenance
- Charging: If you do not use the glue gun for a long time, remember to charge it every 15 days to maintain battery health.
- Cleaning: Ensure the glue gun is completely cool and unplugged before cleaning. Gently wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the glue gun in a dry, cool place, away from direct sunlight and extreme temperatures.
