APPLICATION ADVICE
• Removing paint/lacquer r
-use a clean, sharp scraper
-scrape rmly, when the paint softens
-experiment to establish the length of time necessary to
apply the heat for optimal results
-scrape the softened paint immediately, or it will harden
again
-keep a 30° to 40° angle between the tool and the
workpiece
-remove paint and debris immediately from the scraper
to prevent them from ignition
-scrape with the grain of the wood, wherever possible
-do not direct the hot air ow towards the same surface
for too long
-dispose of all paint debris safely
-thoroughly clean the work area after completing the job
! be careful when removing layers of paint in old
buildings; in the past the building may have been
painted with paint containing lead, which is highly
poisonous
! exposure to even low levels of lead can cause
serious brain and nervous system damage; young
and unborn children are particularly vulnerable
! have lead-based paint removed by a professional
without using a heat gun
OTHER APPLICATION EXAMPLE:
removing (synthetic) wall covering
• Removing paint/lacquer next to glass t
-always use glass protection nozzle G when working
next to glass
-remove the paint with a hand scraper
! do not use the tool for removing paint on metal-
framed windows; metal is heat-conducting which
might lead to breaking of the glass
• Removing stickers (use round nozzle H) y
-many adhesives become softer when heated, allowing
adhesive bonds to be separated and superuous
adhesive to be removed
! heat sticker on the upper side
! always take care not to overheat the underlying
surface
