Operation
Starting Operation
 Observe the mains voltage! The voltage of the power
source must correspond with the data on the type plate of
the machine. Glue guns marked with 230 V can also be op-
erated with 220 V.
Switching On and Off (see figure A)
To save energy, only switch the glue gun on when you are us-
ing it.
– To start the operation of the glue gun, insert the mains
plug into the socket outlet.
Allow the glue gun to heat up for approx. 7 minutes before be-
ginning to work. For this, position the glue gun on the support
stand 5 as shown in the figure.
– To switch off the glue gun, pull the mains plug out of the
socket outlet.
When not using the power tool, pull the mains plug in order to
save energy.
Working Advice
 For longer work breaks, pull the mains plug.
 Do not allow the hot glue or the nozzle tip to come into
contact with persons or animals. Glue and nozzle tip
reach a temperature of approx. 200 °C; danger of burning.
If hot glue comes into contact with the skin, hold the affect-
ed area immediately under a stream of cold water for sev-
eral minutes. Do not try to remove the glue from the skin.
As the result of heat storage, the glue gun can also be used af-
ter it has heated up for a certain time after switching off. When
the glue that emerges starts to become thick, plug the mains
plug into the socket outlet again.
Preparations for Gluing
The surfaces to be glued must be clean, dry and free of
grease. Roughen smooth surfaces before gluing.
 Do not use inflammable solvents for cleaning the sur-
faces to be glued. Solvent remainders can ignite from the
hot glue, or hazardous vapours can develop.
The ambient temperature and the workpieces to be glued may
not be colder than +5 °C and warmer than +50 °C.
Warm rapidly cooling materials (e.g., steel) for better adhe-
sion using a hot air gun or similar.
Gluing (see figure B)
– Allow the glue gun to heat up. Insert the appropriate glue
stick 3 for the material being glued via the opening at the
rear. Press the feed trigger 4 applying moderate pressure.
– Apply the glue in the form of points. For gluing flexible ma-
terials (e.g., textiles), apply the glue in a zig-zag line.
– After applying the glue, immediately press the surfaces to
be glued together for approx. 30 s. The glued spot can be
subjected to load after a cool-down period of approx.
5 minutes.
– Rest the gun on the support stand 5 between individual
gluing runs.

Remove glue residue after cooling with a blunt object. If re-
quired, glued spots can be separated again by applying heat.
Glued spots can be painted.
Changing the Nozzle
– The nozzle 1 can only be changed when in warm condition.
For this, heat up the glue gun for approx. 2 minutes.
 When changing the nozzle, wear protective gloves.
Grasp the hot nozzle only by the heat protection cover
2. Danger of burning when touching the hot nozzle tip.
– Hand-tighten the new nozzle 1.

Maintenance and Service

Maintenance and Cleaning

 Before any work on the glue gun itself, pull the mains
plug from the socket outlet.
 For safe and proper working, always keep the glue gun
clean.
An inserted glue stick 3 cannot be removed out of the rear
opening of the glue gun.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
