Bosch Power Tools LCD Impact Driver User Manual


 
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.
