Keep the charging socket on the tool and on the charger away from other metal objects such as paper clips, coins, keys, nails, screws or other small metal objects that can create a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
If used incorrectly or if the battery is damaged, flammable liquid may be ejected from the battery. Contact with this liquid should be avoided. If contact accidentally occurs, rinse off with water. If the liquid comes into contact with your eyes, additionally seek medical attention. Liquid ejected from the battery may cause irritation or burns.
Do not touch the hot nozzle or the silicone cap. There is a risk of burns.

Important safety rules for the charger

Do not operate the charger on an easily ignited surface (e.g. paper, textiles, etc.) or in a flammable environment. There is a risk of fire due to the charger heating up during operation.

Charging procedure

NOTE: The tool is not fully charged when it leaves the factory. Fully charge the tool before first use.

Insert the charging plug (Fig. 1/ 6 ) into the charging socket (Fig. 1/ 3 ) and ensure that they are connected correctly (Fig. 2)
Insert the USB plug into the computer`s USB port, or plug in the power adapter and con- nect the power adapter to the power socket
When the blue light of the backside LED re- mains lit; this means the charging is completed.

0–24%	1 blue LED strobe flash
25–49%	2 blue LEDs strobe flashes
50–74%	3 blue LEDs strobe flashes
75–99%	4 blue LEDs strobe flashes
100%	4 blue LEDs remain lit

NOTE: During the charging process, the heating of the tool housing is normal. The tool does not work du- EN ring charging. If there is no response when the ON/OFF switch is pressed during charging, it is not a tool fault.

NOTE: The tool works best at normal room temperature.

Preparation and operation

Place the glue stick (Fig. 1/ 4 ) in the opening provided on the back of the tool. Check that a glue stick is fitted properly and only use glue sticks with a diameter of 7 mm.
Press the ON/OFF switch (Fig. 1/ 2 ) for approx. 2 seconds.
Red LEDs on the back of the tool will light up to indicate that the tool is heating up.
After approx. 15 seconds` heating, the tool is now ready for operation. When the temperature is high enough, LEDs will change from red to blue. The tool is ready for operation.
Pull the trigger lever (Fig. 1/ 9 ); the glue flows out of the glue nozzle (Fig. 1/ 1 ).
NOTE: If you don`t pull the trigger lever, the power will turn off after 2 minutes.
To switch the tool off again, press the ON/OFF switch briefly just once.

NOTE: If 4 red LEDs flash, it means you need to insert a new glue stick.

Working with the tool

You can now apply the glue by pulling the trigger lever (Fig.1/ 9 ) after the heating-up time.
Press both surfaces together immediately and apply pressure to them.
It takes about 30 seconds for the glue to set.
The tool switches off automatically after approx. 2 minutes of non-use.

CAUTION: If your gluing work is interrupted or finished, always be sure to stand the tool on your worktable. You can pull out the stand bar to help the tool stand upright on your work table as shown in Fig.1. Switch EN the tool off and allow it to cool down completely before you pack it away.

Troubleshooting

Issue	Solution
Tool does not start/is not operational	Check battery status and charge the

tool by using the USB charging cord (Fig. 1/ 6 ) and plugging it into the TYPE C charging socket (Fig. 1/ 3 ).
Tool is not working properly (glue does not stick together)| Check the heating time of at least 15 seconds after switching on the tool. When the temperature is high enough, LEDs will change from red to blue. Check that you are using the correct glue sticks with a diame- ter of 7 mm, which are intended for use with glue guns.
Tool is not working properly (no glue is flowing out of the nozzle)| Check the heating time of at least 15 seconds after switching on the tool. When the temperature is high enough, LEDs will change from red to blue. Make sure that the glue nozzle (Fig. 1/ 1 ) is clean and that no remaining glue is blocking the new glue. Also check if enough glue is inserted.
