How to prevent overheating
There isn't really much you need to do, as the heat gun has a built-in thermal
protection system. In case of overheating (e.g. due to air build-up), it automatically
shuts off the heating system - but the blower continues to run. When the heat gun
has cooled down to the operating temperature, the heating system is automatically
switched on again.
However.
Do not keep the nozzle too close to the workpiece, as it leads to
excessive hot air build-up, which will lead to overheating. And after operating the
heat gun at a high temperature for a longer period, switch to the position “I” for a
while before switching the heat gun off completely. That's it.
How to use the heat gun for removing varnish or softening
adhesives
Mount the wide jet nozzle
(included). Briefly soften the
varnish applying hot air and
remove it using a sharp, clean
scraper or putty knife. Applying
heat too long will burn the varnish,
making it more difficult to remove.
Many adhesives (e.g. of stickers)
become soft when heated. Heated adhesives allow for bonds to be separated or
excessive adhesive to be removed.
