Programming Operation
In programming operation, it is possible to
continuously store the air-flow and temperature
adjustments in four programs. Each program
allows for different air-flow and temperature
combinations.
In progamming operation, it is also possible to
change the air flow and temperature any time.
When the changes are not saved, they are lost
after switching off or changing to a different
program.
To change to programming operation, press the
program-selection button 6 until the number of
the requested program is indicated in the dis-
play 7.
The following four programs are preset in the
condition of delivery:
1 Deforming plastic tubing
(e.g. LDPE)
2 Welding plastic (e.g. PVC)
3 Removing Varnish/
Softening Adhesives
4 Soldering
To change a set program, switch to this program
by pressing the program-selection button 6. Set
the requested air flow and temperature with the
air-flow control button 8 and the temperature-
control button 9.
As soon as the settings of a program have been
changed, the symbol flashes in the left top of
the display. Once the requested air flow and
temperature are set, press the save button 10
until the symbol in the display goes out. The
set values are now stored under the program
number indicated in the display.

Normal Operation
To switch from programming operation to nor-
mal operation, press the program-selection but-
ton 6 as often as required until no program
number is indicated above the temperature in
the display. The air flow and temperature can be
changed anytime with the air-flow control but-
ton 8 and the temperature-control button 9.
Under the following conditions, the values for
air flow and temperature set in normal opera-
tion will remain stored:
– When changing to programming operation,
– When changing to the cool-air stage,
– When switching the power tool off.

Working Advice

Note: Do not apply the nozzle 4 too close to the
workpiece being worked. The hot air build-up
can lead to overheating of the power tool.
Removing the Heat Protection
The heat protection collar 5 can be removed
when working at particularly hard-to-reach loca-
tions.
Be careful of the hot nozzle! Increased dan-
250
ger of burning exists when working without
350
the heat protection collar.
To remove or mount the heat protection collar 5,
450 switch the power tool off and allow it to cool
down.
550
To cool down the power tool more quickly, you
can operate it for a few moments in the cool-air
stage.
Turn the heat protection collar 5 in anticlock-
wise direction to remove and in clockwise direc-
tion to mount again.
Placing Down the Power Tool (see figure C)
To cool down the power tool or have both hands
free, place it down on the standing surface 1.
Be especially careful when working with the
placed down power tool! There is danger of
burning oneself on the hot nozzle or on the
hot air jet.
