Replacing the heating element
A normal resistance value of a heating element
is 2 to 4
Ω
{at 23
°
C (73
°
F)}.
If the measured resistance value is out of above
range, replace the heating element as shown in
the figure.
Heating element for the
Hakko 815
The heating element is integrated with the heat-
ing core and cannot be separated.
Attempting to do so may damage the heating
element.
WARNING Unplug the power cord before replacing the heating element.
Disassemble the heat-
ing section.
1. Remove the filter pipe and nozzle.
2. Remove the screws (three).
Replacing the heating
element
1. Disconnect the connector and remove the
heating element.
2. Install a new heating element and reassemble.
Remove the screws (three)
Lift up socket part
Disconnect connector
Calibrate the tempera-
ture.
Be sure to calibrate the temperature after re-
placing the heating element in order to ensure
accurate temperature control.
1. Set the temperature control knob to “1” and
heat the nozzle for three minutes.
2. Use a straight-edge (-) screwdriver to adjust the
potentiometer (hole marked CAL) of the station
until the nozzle temperature reads 380
°
C
(716
°
F). We recommend using the Hakko 191
(thermometer) or the Hakko 192 (soldering
tester) to measure the nozzle temperature.
Remove the handle.
Remove the screws (three) and open the
handle.
Note
Should the Hakko 815 ever need repair, please send both the iron and the station to your Hakko agent.
