3. Starting operation

Place desoldering iron into safety holder and connect 7-pin arresting plug to socket
at the front of the unit. Put vacuum tube to connection nipple of the main filter.
Switch on unit. Set temperature to 300°C. The light emitting diode for the visual check
on regulation illuminates.
Intermittent light means that the selected temperature has been reached.
No lumination means that the actual temperatur is higher than the selected tempera-
ture (Hysteresis).
Continuous lumination means that system heats - actual temperature is below set
temperature.
The suction process is starting by actuating the finger-switch.
Wenn desoldering it should be observed that the suction tip is held vertically to the
circuit board surface. Solder must be completely fluid (very important in case of cir-

cuit boards with contacted through-holes). Suck up the solder in a single operation
while circularly moving the connection pin of the component within the hole. If the
solder is not completely removed after the sucking operation (mostly caused by air-
entrance through inclined suction nozzles or by inadequate heating-up) the soldering
joint should be tinned before desoldering. Regular retinning increases the lifetime of
tiplets.
Adaption Possibility for Left Handers
Through detaching the 4 flange screws (see page 21) the desoldering iron can be twi-
sted against the handle by 120°.
As soon as the screws are removed, only turn the desoldering iron but do no draw
out of the handle as this could damage the heating element.
After twisting the desoldering iron by 120°, fasten the flange-screws. Now the desol-
dering iron is ready for use with the left hand.
Cleaning DS 22 / DS 80
To obtain good desoldering results, it is important to regularly clean the desoldering
head. This includes emptying the solder collecting container, replacing the glass tube
filter, as well as checking the seals. Correct sealing of the front faces of the glass cylin-
der ensures full suction performance. Dirty filters affect the air flow rate through the
desoldering tool. To clean the suction nozzle bore and the suction tube, use the clea-
