power cord from heat, oil and sharp 
edges.

Safety warnings 

Residual heat indicator

The residual heat indicator serves 
as a visual warning to prevent inju-
ry from direct contact with the hot 
nozzle outlet. The residual heat indi-
cator also works when the tool is un-
plugged. The indicator starts working 
after the tool has been in use for  
90 seconds and keeps flashing until 
the temperature at the nozzle outlet 
has fallen below 60 °C at room tem-
perature. The residual heat indicator 
does not show if the tool has been in 
operation for less than 90 seconds. 
Responsibility always rests with the 
user as care must be taken at all 
times when handling hot air tools. 

Keep these safety precautions 
with the tool.

Tool description - Operation

Please note

: The distance from the object you are working 

on depends on material and intended method of working.  

Always try out the airflow and temperature on a test piece 

first. Using the attachable accessory nozzles (see accesso-

ries page on the cover) the flow of hot air can be controlled 

with maximum precision.

Take care when changing hot nozzles!

 When using  

the hot air tool in the self-resting position, make sure it is 

standing on a stable, non-slip and clean surface.

Switch-on procedures generate short-term voltage drops. In 

unfavourable grid conditions, adverse effects can occur on 

other devices. With grid impedances of less than 0.35 ohms, 

no disturbances are expected.

1. Operation

The tool is switched on and off at the ON/OFF switch 

12

  

on the back of the grip handle. The joystick 

10

 is used for 

controlling temperature and airflow or fan speed. 

2. Setting the temperature

Temperature can be infinitely varied over a range of 50-700 °C 

at the joystick on the control panel with LCD display. The ac-

tual temperature is measured at the hot air outlet nozzle and 

indicated on the display. The joystick 

10

 is used as an input 

button with plus/minus function.

Briefly pressing the "

+/–

" joystick increases or reduces the 

temperature setting in 10 °C steps. Keeping the joystick 

pressed speeds up the temperature setting process. Once 

the temperature has been set, the tool takes a few seconds 

to reach temperature (depending on speed/airflow). The  

temperature setting selected is shown on the display for  

3 seconds. The display then shows the current actual tem-

perature. The "°C/°F" symbol continues to flash until the 

selected temperature is reached.

If you want to alter the setting, simply press the joystick 

again to increase or reduce the temperature. After switching 

off, the hot air tool stays in the last setting.

3. Setting airflow rate

To change the airflow rate, first press the button for airflow 

mode 

8

; the fan symbol flashes. Now use the joystick to 

set the airflow rate. The airflow rate setting mode automati-

cally closes if the airflow rate setting is not changed within 

5 s. Pressing the the airflow button again after setting the 

airflow rate immediately closes the airflow rate setting mode. 

The airflow rate can be varied from a minimum of 150 l/min  

to a maximum of 500 l/min.

4. Programming mode [P]

Four programmes are factory-set for the most common 

types of work. Press button "P" for programming mode. 

Number 1 is displayed for programme 1. Continuing to press 

the programme selection button will take you to programmes 

2 – 4. Pressing the button again will return the tool to normal 

operation.
