1. Slide the handle cover (2) toward the cord and remove the screw (1)
securing the heating element.
2. Turn the nut (3) counterclockwise and remove it.
3. Remove the tip (4).
4. Pull both the heating element (5) and the cord toward the tip of the
iron and out of the handle (6).
Measure the resistance values at the sensor and the heating element
of the terminal board.
The resistance value should be the same as for the 907, 908.
To replace the heating element, refer to the instructions included with
the replacement part.
1. Turn the unit ON and set the temperature control knob to 480°C (896
°F). Then wiggle and kink the iron cord at various locations along
its length, including in the strain relief area.
If the LED heater lamp flickers, then the cord needs to be replaced.
CAUTION
The LED heater lamp will flicker even with a normal Iron cord if
the temperature reaches 480°C (896°F).
2. Check the resistance between the pin of the plug and the wire on
the terminal.
Pin 1: Red Pin 2: Blue Pin 3: Green Pin 4: White Pin 5: Black
The value should be 0 Ω. If it is greater than 0 Ω or is ∞, the cord
should be replaced.
Refer to the drawing in the replacement parts section of this manual.
Desolder the blown fuse and remove it. Solder on a new one.
2. Broken Soldering Iron Cord
There are two methods of testing the
soldering iron cord.
3. Replacing the Fuse
