Performing proper and periodic maintenance extends product life and contributes to the
quality of soldering work. Efficient soldering depends upon the temperature, the quality and quantity of
the solder and flux. Apply the following service procedure as dictated by the conditions of the usage.
Since the tip can reach a very high temperature, please work carefully.
Except where indicated, always turn the power switch OFF and disconnect the power plug
before performing any maintenance procedure.
High temperatures shorten tip life and may cause thermal shock to components.
Always use the lowest possible temperature. The excellent thermal recovery characteristics
of the HAKKO FX-888D ensures effective soldering at low temperature.
Always clean the tip before use to remove any residual solder or flux adhering to it.
Use a cleaning sponge or the HAKKO 599B tip cleaner.
Contaminants on the tip may have negative effects, including reduced heat conductivity,
which contribute to poor performance.
Never allow the unit to idle at a high temperature for extended periods. This will allow the
tip to become oxidized. Turn the power switch OFF. If it is to be out of service for
several hours, it is advisable to disconnect the power plug as well.
Always clean the tip and coat it with fresh solder after use. This guards against oxidation.
1. Set the temperature to 250℃(482℉).
2. When the temperature stabilizes, clean the tip and
check the condition of the tip. If the tip is badly worn or deformed, replace it.
3. If the solder plated part of the tip is covered with black oxide, apply fresh solder,
containing flux, and clean the tip again. Repeat until all the oxide is removed,
then coat the tip with fresh solder.
4. Turn the power OFF and remove the tip, using the heat resistant pad. Set the tip aside to
cool.
Do not file the tip in an attempt to remove the black oxide.
Disconnect the plug of the cord assembly
and measure the resistance value
between the pin of the connecting plug as follows.
If the values of “a” and ”b” are outside
the value in the table, replace the heating
element(sensor) and/or cord assembly.
If the value of “c” is over the value in the
table, remove the oxidization film by lightly
rubbing with sand-paper or steel wool
the points shown in the drawing on the right.

1. Loosen the nipple by turning it counterclockwise.
2. Pull out the tip.
3. Remove the screw and strut pin. Separate into handle A and B.
Remove the tension spring.
Do not lose the tension spring.
4. Remove each tapping screw of the handle A and B, and remove the handle cover.
5. Pull out the P.W.B. and heating element.
*Measure when the heating element is at room temperature.
1. Heating element resistance (red) 2.5-4.5 Ω
2. Sensor resistance (blue) 43-58 Ω
If the resistance value is not normal, replace the heating element.
(Refer to the instructions included with the replacement part.)
After replacement
1. Measure the resistance between pins 4 and 1, 4 and 2, 5 and 1, 5 and 2.
If it is not ∞, the heating element and sensor are touching. This will damage the circuit board.
2. Measure the resistance “a” , “b” and “c” to confirm that the leads are not twisted and that
the grounding spring is properly connected.
There are two methods of testing the cord assembly as below.
1. Turn the power on and set the temperature control knob to 400℃(752℉). Then, bend the cord
at various locations along its length, including in the strain relief area.
If the LED heater lamp flashes, then the cord needs to be replaced.
2. Check the resistance between the plug pin and the terminal lead.
Pin 1: Red Pin 2: Blue Pin 3 : Green
Pin 4 : White Pin 5 : Black
If it is higher than 0 Ω or ∞, the cord should be replaced.
The power lamp starts to flash when the temperature reaches 400℃(752℉)
regardless of the condition of the cord.
