# Application tips

## Processing temperature

Two different processing temperatures (130 °C and 200 °C) can be set on the glue gun.

If you change the processing temperature during operation, the relevant temperature selection button (7) or (9) will flash green until the target temperature required is reached. The cooling process from 200 °C to 130 °C may take several minutes.

Processing temperature | Material
--- | ---
130 °C Temperature selection button (9) | Heat-sensitive materials (e.g. Styropor®); not suitable for PE, PP, PTFE and plasticised PVC
200 °C Temperature selection button (7) | Paper, cardboard, cork, wood, leather, textiles, foam materials, plastic (except PE, PP, PTFE and plasticised PVC), ceramic, porcelain, metal, glass and stone

Only use adhesives that have been recommended by the manufacturer of the glue gun and that are suitable for the processing temperature.

## General work and cleaning tips

Material/workpiece | Recommendation
--- | ---
Long workpieces with large surface areas | Apply adhesive in dots
Flexible materials (e.g. textiles) | Apply adhesive in lines

- Do not use flammable solvents to clean the bonding locations. The hot glue could ignite any solvent residue or release hazardous fumes.

Adhesive residue on clothing cannot be removed.

The bonding locations can be painted.

## Errors – causes and corrective measures

Problem | Cause | Corrective measures
--- | --- | ---
Glue stick is not being conveyed. | Glue stick has been used up | Insert a new glue stick
Glue stick diameter is too large or too small | Only use recommended original glue sticks
Glue stick is too short | Only use recommended original glue sticks
Insert another glue stick
Glue stick falls out of the glue gun. | Glue stick diameter too small | Only use recommended original glue sticks
Adhesive continues to flow or drip for a long time after feed is stopped. | Melting point of glue stick is too low | Only use recommended original glue sticks
Set the correct processing temperature with the temperature selection button
Glue gun drips constantly without any pressure being applied to the feed trigger. | Melting point of glue stick is too low | Only use recommended original glue sticks
Set the correct processing temperature with the temperature selection button
Feed is sluggish. | Glue stick diameter is too large and/or melting point of glue stick is too low | Only use recommended original glue sticks
Set the correct processing temperature with the temperature selection button
Feed is blocked by glue leaking from the rear of the glue stick. | Glue stick diameter is too small and/or melting point of glue stick is too low | Only use recommended original glue sticks
Set the correct processing temperature with the temperature selection button
Adhesive does not flow evenly. | Melting point of glue stick is too low | Only use recommended original glue sticks
Set the correct processing temperature with the temperature selection button
Feed is not even | Press the feed trigger slowly and apply even pressure
Bonding surface is only holding fast in one place. | Glue has already partly cooled before the components were pressed together | Press workpieces together faster
Apply adhesive in glue dots or lines instead of covering the whole surface
Pre-heat the bonding surface with a heat gun
Set the correct processing temperature
Bond becomes unstuck after it cools. | Bonding surface is greasy or too smooth | Remove the grease from the bonding surface or roughen it a little
Bonding surface is dusty | Clean the bonding surface
Workpiece material is not suitable | Hot melt adhesive is not suitable, use special adhesive
Exposure to moisture | Only use in a dry environment
Ambient temperature too high/too low | Only use within the specified temperature range
Glued tiles in damp rooms become unstuck. | Moisture is penetrating the bonding location. | Hot melt adhesive is not suitable, use a cement-based tile adhesive
Glued shoe soles are becoming unstuck. | Moisture expands leather and penetrates the bonding location. | Hot melt adhesive is not suitable, use special adhesive
"Threads" develop as the glue gun is removed from the bonding location after applying adhesive. | Feed trigger is still pressed when the application of adhesive is finished | Stop the feed just before finishing applying adhesive
Nozzle has not been wiped clean | At the end of gluing and before removing the glue gun from the bonding location, wipe the nozzle against the workpiece
Workpiece is melting. | Workpiece is made of a material with too low a melting point, e.g. Styropor®. | Hot adhesive unsuitable Use special adhesive (low-melt) and set the processing temperature to 130 °C with the temperature selection button (9)
Fingers are being burned while gluing. | Adhesive is puncturing paper when applied. | Do not hold the workpiece in your hands
Carry out gluing on a heatproof silicone mat
Adhesive is puncturing threads when applied. | Do not hold the workpiece in your hands
Carry out gluing on a heatproof silicone mat
Metal workpiece is heating up | Do not hold the workpiece in your hands
Carry out gluing on a heatproof silicone mat
Clamp the workpiece
