Preparations for Gluing
The surfaces to be glued must be clean, dry and free of
grease.
The materials to be glued as well as the surface on which you
are working may not be easily ignitable or inflammable.
Check the suitability of heat-sensitive materials first on a test
workpiece.
The ambient temperature and the workpieces to be glued may
not be colder than +5 °C and warmer than +50 °C.
Materials, such as metal, which cool off the glue quickly,
should be preheated with a hot air gun.

Practical Advice

Material/Workpiece Recommendation
Large-surfaces, long Apply the glue in the form of
workpieces points
Flexible materials Apply the glue in lines
(e.g. textiles)
Troubleshooting – Causes and Corrective Measures
Problem
The glue stick is not transported.
Glue stick falls out of glue pen.
Long after-run or dripping period
after relieving the feed.
Glue pen dripping continuously
without feed actuated.
Feed blocked through glue
escaping toward the rear.
Glue does not flow uniformly.
Adhesive surface only bonds on
one side.
Adhesive bond comes undone
after cooling.
Glued tiles in damp locations come
undone.
Bosch Power Tools
Gluing (see figure B)
– Insert the appropriate glue stick 6 for the material being
glued via the opening at the rear of the glue pen.
– Switch the glue pen on and allow it to heat up (see "Switch-
ing On", page 10).
The glue pen is ready for operation after approx. 15 sec-
onds.
– Press the feed trigger 3 applying moderate pressure.
– Apply the glue only on one side (also see "Practical Ad-
vice", page 11).
– After applying the glue, immediately press the surfaces to
be glued together. Correcting the gluing location is still
possible at this point.
The glued spot can be subjected to load after a cool-down
period of approx. 2 minutes.
Remove glue residue after cooling with a blunt object. If re-
quired, glued spots can be separated again by applying heat.
 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.
Glue remainders on clothing cannot be removed.
Glued spots can be painted.
Cause
Glue stick used up.
Glue stick diametre too large or small.
Glue stick too short.
Glue stick diametre too small.
Melting temperature of glue stick too
low.
Melting temperature of glue stick too
low.
Glue stick diametre too small.
and/or
Melting temperature of glue stick too
low.
Melting temperature of glue stick too
low.
Feed not uniform.
Adhesive already partially cooled off
before components have been joined.
Adhesive surface greasy or too smooth. Degrease adhesive surface or roughen slightly.
Adhesive surface dusty.
Material of workpiece not suitable.
Moisture creeps under bonding location. Adjesive not suitable.
Corrective Measure
Insert a new glue stick.
Use recommended original glue sticks.

Wait for heating time of glue pen to elapse.
Actuate feed trigger slowly and uniformly.
Join workpieces quicker.
Set gluing points or beads instead of applying
glue over surface.
Pre-heat adhesive surface with hot air blower.
Clean adhesive surface.
Adjesive not suitable.
Use specialty adhesive.
Use specialty adhesive on cement basis.
