Operating manual
Depending on the age of the foil bag, gas pressure can build up inside, causing the foil to
swell. This may make insertion difficult. Here it is advisable to pierce the foil near the clip
with a needle. This allows the excess pressure to escape. However, this has no effect on the
corresponding adhesive.
Nozzle: In the event of longer work interruptions (up to 12 hours), the adhesive that has
escaped from the nozzle teeth will harden. Here we recommend removing excess adhesive
with Bona Cleaning Wipes and covering the outlet openings with adhesive tape. In the case
of longer interruptions, the nozzle must be cleaned or, if necessary, replaced with a new one.
Cured adhesive should not be squeezed out by squeezing the following adhesives. This can
lead to damage to the drive or severe contamination.
Feed: The toothed rack is set at the factory so that it does not exceed that marked with a
red arrow marked marking drives out. When the point is reached, the adhesive application is
interrupted.
Temperature-dependent Overload Protection
If the permissible temperature is exceeded, the caulking gun switches off. Let the caulking
gun cool down and then switch the caulking gun back on.
