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.
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.
Practical Advice
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.
Troubleshooting – Causes and Corrective Measures
Material/Workpiece
Recommendation
Large-surfaces, long
workpieces
Apply the glue in the form of
points
Flexible materials
(e.g. textiles)
Apply the glue in lines
Problem
Cause
Corrective Measure
The glue stick is not transported.
Glue stick used up.
Insert a new glue stick.
Glue stick diametre too large or small.
Use recommended original glue sticks.
Glue stick too short.
Use recommended original glue sticks.
Insert a new glue stick.
Glue stick falls out of glue pen.
Glue stick diametre too small.
Use recommended original glue sticks.
Long after-run or dripping period
after relieving the feed.
Melting temperature of glue stick too
low.
Use recommended original glue sticks.
Glue pen dripping continuously
without feed actuated.
Melting temperature of glue stick too
low.
Use recommended original glue sticks.
Feed blocked through glue
escaping toward the rear.
Glue stick diametre too small.
and/or
Melting temperature of glue stick too
low.
Use recommended original glue sticks.
Glue does not flow uniformly.
Melting temperature of glue stick too
low.
Wait for heating time of glue pen to elapse.
Feed not uniform.
Actuate feed trigger slowly and uniformly.
Adhesive surface only bonds on
one side.
Adhesive already partially cooled off
before components have been joined.
Join workpieces quicker.
Set gluing points or beads instead of applying
glue over surface.
Pre-heat adhesive surface with hot air blower.
Adhesive bond comes undone
after cooling.
Adhesive surface greasy or too smooth. Degrease adhesive surface or roughen slightly.
Adhesive surface dusty.
Clean adhesive surface.
Material of workpiece not suitable.
Adjesive not suitable.
Use specialty adhesive.
Glued tiles in damp locations come
undone.
Moisture creeps under bonding location. Adjesive not suitable.
Use specialty adhesive on cement basis.
