Paint Stripping Safety Instructions
WARNING
!
paint.
The peelings, residue and vapors of
paint may contain lead, which is poisonous.
Any pre-1977 paint may contain lead and
paint applied to homes prior to 1950 is likely
to contain lead. Once deposited on surfaces,
hand to mouth contact can result in the
ingestion of lead. Exposure to even low
levels of lead can cause irreversible brain
and nervous system damage; young and
unborn children are particularly vulnerable.
Before beginning any paint removal process
you should determine whether the paint you
are removing contains lead. This can be
done by your local health department or by a
professional who uses a paint analyzer to
check the lead content of the paint to be
removed. LEAD-BASED PAINT SHOULD
ONLY BE REMOVED BY A PROFESSIONAL
AND MUST NOT BE REMOVED USING A
HEAT GUN.
Persons removing paint should follow
these guidelines:
1) Move the work piece outdoors. If this is
not possible, keep the work area well
ventilated. Open the windows and put an
exhaust fan in one of them. Be sure the fan
is moving the air from inside to outside.
2) Remove or cover any household items
in the area such as carpets, rugs,
furniture, and clothing, cooking utensils
and air ducts.
3) Place drop cloths in the work area to
catch any paint chips or peelings.

Operating Instructions
Your Bosch Heat Gun is a heavy-duty,
industrial-quality, general-purpose heat gun.
You can do more heating jobs faster with this
heat gun because of its high power and air
flow ratings.
This product provides a fast flow of heated air
for applications such as activating adhesives,
bending and forming plastics, curing epoxies,
deburring plastics, defrosting frozen coils,
drying negatives and parts, heating solids and
liquids, loosening nuts and bolts, removing
floor tiles and putty, repairing vinyl, shrinking
tubing and packaging, softening materials
and stripping paint.
The proper amount of heat for each
application is dependent upon, the distance of
the nozzle opening from the work surface and
length of time that heat is applied to the work
surface.
Before performing an application, we
recommend that you experiment with a piece
of scrap material. Use care in approaching
the work until you find the proper combination
of shutter adjustment, distance from the work
surface and heat application time.
Use a gentle back and forth motion when
applying heat unless it is found that a
concentrated heat is desired.
OFF/COOL/HOT SELECTOR SWITCH
To turn unit on, slide the selector switch to the
position (cool air setting) or (hot air setting.)
In both positions, the unit starts with the air flow
and temperature values that were set before
the last switch-off.
To turn unit off, slide the selector switch to the
O stop position.
When working for long periods of time with high
temperatures, allow the unit to cool down by
running the unit in the cool air setting before
turn the unit off (Fig. 1).
When heat gun is used in an enclosed
container, such as a shrink tunnel or special
enclosure, ambient air must be allowed to
pass into the heat gun and there must be an
outlet of equal size for the heated air to pass
out of the enclosure also. Total enclosure will
cause damage or possible failure to the heat
gun due to the extreme heat generated.
COOL AIR SETTING
The air flow can be regulated, but
the temperature is fixed at 120 °F
(cannot be regulated), and no
programmed operation is possible.
The cool air setting is suitable for cooling a
warmed workpiece, or for drying of paint. It is
also used for cooling the unit before placing
down or the changing of nozzles.
When changing from the hot air setting with
high temperatures to the cool air setting , a
short period of cooling period is required until
the unit cools down to 120 °F. During this
cooling period, the actual temperature of the
nozzle outlet is shown in the display (Fig. 1) .
When changing from the hot air setting to the
cool air setting , the current air flow setting is
used.
HOT AIR SETTING
The air flow and temperature can
be regulated, normal and
programmed operation is possible.
For applications, see Typical
Applications. When changing from the cold air
setting to the hot air setting , air flow,
temperature, operating mode and program
revert back to the settings that were in use
when the hot air setting was last used.
SETTING THE TEMPERATURE
The temperature in the hot air setting can be
adjusted (Fig. 2).
To change to another temperature, the unit
needs a short time to warm or cool the air
stream to the target temperature. The target
temperature is shown in the display during this
time with blinking arrows .
After reaching the required temperature, the
arrows are eliminated and the display
shows the actual temperature.
The target temperature can be increased in
steps of 10°F by pressing the “+” side of the
temperature button or reduced by pressing the
“–” side of the button. Brief pressing of the
button increases or decreases the target
temperature one time by 10°F. Longer pressing
of the button increases or decreases the
temperature continuously by 10°F steps until
the button is released or the minimum or
maximum temperature is reached.

BM 1619929572 08-07 8/28/07 9:45 AM Page 8
The air flow can be regulated with the air flow
button (Fig. 1).
The CFM at each of the 10 airflow settings
depends on the temperature setting. For
example, at the lowest temperature (120
degrees) the lowest airflow setting delivers 3.6
cfm, whereas at the highest temperature (1200
degrees) the lowest airflow setting delivers 8.8 cfm
The air flow can be increased by pressing the
“+” side of the air flow button or decreased by
pushing the “–” side of the button. Brief
pressing of the button increases or decreases
the air flow by one step. Longer pressing of the
button increases or decreases the air flow
continuously until the maximum or minimum air
flow is reached.
Decrease the air flow when, for example:
The surroundings of the workpiece should not
be heated more than necessary. A light
workpiece could be blown away by the air
stream.
In programmed operation, air flow and
temperature settings can be stored in four
programs. In each program, any air flow and
temperature combination are possible.
Also in programmed operation, air flow and
temperature can be changed at any time. If the
changes are not stored through
reprogramming, they are lost when switching
the unit off or when changing to another
program.
To use one of the pre-stored modes, press the
program selection button
of the required program ( , , or ) as
shown in the display (Fig. 2).
The unit is equipped with the following four prestored programs:

Typical Applications
Temperature settings given in the application
examples are suggested values that,
depending on the material characteristics, can
deviate. The distance between the nozzle and
workpiece is dependent on the material to be
processed.
The ideal temperature should first be
ascertained by performing a test. Therefore,
begin with a lower temperature setting.
All application examples (except figure 5) can
be performed without accessories. However,
the use of the recommended accessories
simplify the work and significantly improve the
quality of the results.
WARNING
!
Be careful when changing the
nozzle, danger of burning! Do
not touch the hot nozzle. Allow the unit to cool.
Wear protective gloves.
Bosch stocks a range of accessories (see
Bosch catalog) which facilitate a wide range of
other applications.
STRIPPING PAINT/SOFTENING ADHESIVES
Attach the optional HG010 spreader nozzle.
Soften the paint using hot air and remove
evenly using a spatula. Do not heat the paint for
too long since this will burn the paint, making it
more difficult to remove (Fig. 4).
2. As paint begins to blister and bubble, move
gun slowly in a steady progression across
the surface. Follow closely with a scraping
knife (a 2-inch wall scraper works best) to
scrape the loosened paint. Preheat scraper
as you are heating the paint surface. This
increases the speed of paint stripping.
a. Removal of paint by using heat is based
on the fact that all organic paints soften
at elevated temperatures. When soft, the
paint can be easily lifted off without
damage to the surface.
b. When stripping paint from grooves in
moldings, you can devise your own
scraping tools. Old screwdrivers with
ground-down blades and linoleum
knives are often used.
REMOVING PAINT FROM WINDOW
FRAMES
Danger
of glass breaking!
Use of the optional HG030 deflector nozzle is
essential.
On profiled surfaces, paint can be removed
using a spatula and brushed off using a soft
wire brush (Fig. 5).
FIG. 4
Many adhesives (e.g. stickers) become softer
when heated allowing adhesive bonds to be
separated or superfluous adhesive to be
removed.
1. To strip paint, turn unit on and hold it about
1 inch from the surface being stripped.
Proper distance and speed of stripping
should be determined by experience. It is
an advantage to hold the gun further from
the surface and to move forward slowly.
Slower speed is compensated by the wider
softened areas. Heat will also penetrate
deeper.
FIG. 5
SHAPING PLASTIC TUBING
Attach the optional HG040 reflector nozzle. To
avoid kinking the tubing, fill the tubing with sand
and seal at both ends (Fig. 6).
Heat the tubing evenly by moving it from side to
side.

SOFT SOLDERING
For point soldering, attach the optional HG020
concentrator nozzle. For soldering of pipes,
attach optional the reflector nozzle.
If solder without flux, apply soldering grease or
paste to the location to be soldered. Warm the
location to be soldered for 50–120 seconds on
the material. Apply the solder. Heat the
workpiece and allow it to melt the solder. Do
not heat the solder directly. After the soldered
location has cooled, remove the flux (Fig. 9).
