Operating Modes
Cool-air Stage
The air flow can be regulated, the
temperature is set to 50 °C (cannot
be regulated), and programming
operation is not possible.
The cool-air stage is suitable for cooling down
a heated-up workpiece or for drying paint. It is
also suitable for cooling down the power tool
before placing it down or changing nozzles.
When changing from the hot-air stage with high-
er temperatures, it will take a few moments until
the power tool has cooled down to 50 °C. During
cooling down, the display 7 indicates the actual
temperature at the nozzle outlet.
When changing from the hot-air stage to the
cool-air stage , the current air-flow settings are
taken over.
Hot-air Stage
The air flow and temperature can be
regulated; normal and programming
operation are possible.
When changing from the cool-air stage to the
hot-air stage , the air flow, temperature and pos-
sibly the program are automatically adjusted ac-
cording to the settings of the last hot-air stage
operation.
Programming Operation
In programming operation, it is possible to con-
tinuously store the air-flow and temperature ad-
justments in four programs. Each program allows
for different air-flow and temperature combina-
tions.
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
display 7.
The following four programs are preset in the
condition of delivery:
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 tem-
perature are set, press the save button 10 until
the symbol in the display goes out. The set val-
ues are now stored under the program number
indicated in the display.
