OPERATION
6
Always use the correct supply voltage!
The voltage of the power source must agree with the value given on the nameplate
of the unit. Units designated for 230V can also be operated with 220V.
Switching On/Off
Switching On
- To put into operation, slide the switch 3 to position I or II.
Switching Off
- To switch off, slide the on/off switch 3 to the stop at position 0.
HAG3LCD
：
After working for a longer time with high temperature, allow the unit to
cool by running in the cold air setting I before switching off.
Thermo-Protection Switch-Off (HAG3LCD)
When the heater is overloaded (e.g. as a result of restricted air flow), the unit
switches it off automatically, however, the blower continues to run. When the unit
has cooled to operating temperature, the heater is switched on again.
Setting the Air Flow and Temperature (HAG1)
The switch 3 can be set to one or two blower steps. Suitable air flow and
temperature combinations can be selected according to the applications.
Step Air Flow Temperature
I / II 240 / 450 l/min 250°C / 550°C
Setting the Air Flow and Temperature (HAG3)
The switch 3 can be set to one or two blower steps. Suitable air flow and
temperature combinations can be selected according to the applications.
Step Air Flow Temperature
I 250 l/min 50-450°C
II 500 l/min 60-600°C
Within these limits temperature change adjustment wheel 4.
Setting the Air Flow and Temperature (HAG3LCD)
The air flow can be set with the switch 3 in two steps, steps I and II.
Step Air Flow Temperature
I 250-500 l/min 60°C
II 250-500 l/min 60-630°C
Decrease the air flow when, for example:
- The surroundings of the work piece should not be heated more than necessary
- A light work piece could be blown away by the air stream.
The cold air setting I is suitable for cooling a warmed work piece or for the drying
of paint.
It is also suitable for cooling the unit before placing down or the changing of nozzles.
In this step, the temperature won’t change when push the temperature setting
button 5 or 6.
But the air flow will change when push the air flow setting button 4 or 7.
In the blower steps II, the temperature and air flow can be continuously regulated.
After switching to the blower steps II, after displaying the target temperature,
the actual temperature at the nozzle outlet is shown with blinking.
The target temperature can be increased in steps of 10°C by pressing the button 5
or reduced by pressing the button 6. Brief pressing of the button increases or
decreases the target temperature one time by 10°C.
Longer pressing of the button increases or decreases the temperature continuously
by 10°C steps until the button is released or the minimum or maximum temperature
is reached.
The air flow would getting stronger when pushing the air flow setting button 7,
and the air flow would be depressed when pushing the air flow setting button 4.
There are altogether 5 speed to set the air flow.
In the blower step I, the pre-set temperature is 60°C.
When switching from blower step with higher temperatures to blower step I ,
a short time is required until the unit has cooled to 60°C.
During the cooling period, the display 8 shows the actual temperature at the nozzle
outlet.
Removing the Heat Protector
For working in especially narrow places, the heat protector can be removed.
Be careful of the hot nozzle! Increased danger of burning exists when working
without the heat protector.
To remove or mount the heat protector, the unit must be switched off and have
cooled.
For cooling, run briefly in the cold setting, if necessary.
Turn the heat protector counter clockwise to remove and clockwise to mount again.
Placing Down the Unit (Picture A)
For cooling of the heated unit or to have both hands free for working, the unit can
be place down in the upright position on the rear housing surface.
•
Be especially careful when working with the upright unit! There is danger of
burning on the hot nozzle and the hot air stream.
Working Examples
Temperature settings given in the application examples are suggested values that,
depending on the material characteristics, can deviate. The distance between the
nozzle and work piece is dependent on the material to be processed.
The ideal temperature should first be ascertained by performing a test.
Therefore, begin with a lower temperature setting.
All application examples can be performed without accessories. However,
the use of the recommended accessory parts simplify the work and significantly
improve the quality of the results.
Be careful when changing the nozzle, danger of burning!
Do not touch the hot nozzle. Allow the unit to cool.
Wear protective gloves.
An extensive range of accessories are stocked which offer a wide range of other
applications.
