Note: Always set the heat gun upright (nozzle pointed up) after it is turned off, either for a
short break or for storage. Avoid laying the unit on the side after shutdown. The heat will
remain in the unit and cooling will take longer. Store the unit only after the nozzle is cool.
Unplug the unit before storing to prevent accidental startup.
IMPORTANT: Always protect glass when working near windows.
Do not touch nozzle or the scraper blade when working. These become
extremely hot and will cause severe burns. Wear gloves to protect hands
from hot scrapings.
Stripping Paint
The heat gun heats up the surface and causes the paint to soften, at which time it can be
scraped off easily without damaging the surface. Some paints may soften even though they do
not blister; some may become rubbery, and some may require higher heat.
When working with several layers of paint, it speeds up the scraping process to heat the surface
thoroughly, all the way to the wood. Then all the layers can be scraped at one time.
A soft wire brush may be the best tool to use for very intricate surfaces. Mineral paints and
finishes, such as cement paint and porcelain, do not soften with heat, so using a heating tool will
not work for paint removal.
The best method of paint removal
Move the gun slowly and steadily forward at an angle
to the surface, pointing the nozzle in the direction of
motion. This allows you to scrape safely outside the hot
air stream and keeps the scraper and the scraped surface
cooler.
A. Warm air preheats the surface.
B. Paint is softened by hot air.
A + B. Deep penetration of heat over total area.
C. Paint can be easily scraped off as soon as it is
softened and the gun is moved forward.
D. Stripped surface allowed to cool.
Note: Do not use the heat gun on surfaces that can be damaged by heat, such as vinyl-
coated paneling, siding or window frames.
When removing paint from window frames, the heat gun will soften the putty. Be careful
not to gouge the putty with the scraper. The putty will firm up after it cools.
Do not use the heat gun on insulating laminated window glass such as Thermopane. The
glass edge expansion may break the edge seal.
When scraping fascia, do not overheat the edges of the asphalt shingles protruding over
the edge of the sheathing. Too much heat will melt the asphalt.
IMPORTANT: The removal of paint by heat gun is safe if the above guidelines are used,
but always keep either a container of water or an ABC fire extinguisher within reach.
IMPORTANT: Read the general operating and safety information sections of this owner's
manual before using the heat gun.
