Initial Use
A coating applied at the factory protects
metal surfaces from corrosion. This protec-
tive coating will burn off during initial use
and smoke may be observed. The heat gun
may also display discolorations on the nozzle
caused by the normal operating tempera-
tures. This does not indicate damage and the
function of the tool is not affected.
Selecting Power Setting
The output level setting (Fig. 1, 3) has two
different output temperature levels, 570 °F
and 930 °F (300 °C and 500 °C). The LED
work light (6) flashes briefly to indicate that
the temperature setting change is made.
To select 570 °F push the output level setting
(3) down, toward the bottom of the tool. To
select 930 °F, push the output level setting
(3) up.
Switching On/Off
To switch the tool on, first press the lock-off
button (Fig. 1, 4) and then the on/off trigger
(5). After the tool has been turned on, you
can release the lock-off button (4).
To switch the tool off, release the on/off trig-
ger switch (5).
Restart Protection
If the battery pack (Fig. 1, 9) is removed from
the heat gun while in operation, the restart
protection is activated and the LED work
light (6) flashes until the on/off switch (5) is
released. To resume operation, first ensure
a battery pack has been inserted. Next, turn
the tool off and then back on by releasing and
then pressing the on/off trigger switch (5).
Overheat Protection for the
Battery Pack
If the battery pack (Fig. 1, 9) gets excessively
hot during operation, the output is reduced.
The LED flashes slowly for as long as the on/
off trigger switch (5) is pressed. If the heat
gun continues to be operated and the tem-

perature in the battery pack increases fur-
ther, the heat gun will switch off.
Reduced Output
Battery packs rated 4.0 Ah and above are rec-
ommended to achieve the maximum airflow
and temperature levels listed in the Specifi-
cations section. Activating the heat gun with
a battery pack rated less than 4.0 Ah will
cause the LED work light (Fig. 1, 6) to flash
slowly several times. This indicates the heat
gun is operating with reduced output.
Built-in Work Light
Upon starting the heat gun, the LED work
light (Fig. 1, 6) switches on and illuminates
the work area.
The LED work light (6) is also used as a sta-

Operating Tips
To maintain the desired heating and prevent
possible damage, do not position the nozzle
(1) too close to the workpiece. Positioning
the nozzle too close to the workpiece could
result in air blockage and can lead to the over
heating of the heat gun.
