The HAKKO FX-889 has the following parameters.
Performing proper and periodic maintenance extends product life. Efficient soldering depends upon
the temperature, quality and quantity of the solder and flux.
Apply the following service procedure as dictated by the conditions of usage.
●Tip Maintenance
1. Set the temperature to 250℃(482℉).
2. When the temperature stabilizes, clean the tip with the cleaning sponge and check the condition of the tip.
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. If the tip is deformed or heavily eroded, replace it with a new one.
1. Press and hold the button for at least
two seconds.
●is displayed. When you press the
button, the display will move to the adjust mode.
2. Changing from to .
●The procedure for changing the value in
adjustment mode is the same as setting the
temperature in normal mode.
Please refer to Section 5 - OPERATION.
3. Press the button to exit the setting after
changing the values.
● The tip temperature will be adjusted accordingly.

The unit will move to the change setting screen for each mode after entering the password.
Please change the setting for each mode according to the procedure.
Enter the parameter setting to change the mode. (Please refer to [6. PARAMETER SETTING])
B. The preset mode
The HAKKO FX-889 has a preset mode that will allow the unit to store up to 5 preset temperatures you
can change between instead of using the above normal mode.
Initial preset temperatures
P1: 250℃ (482℉), P2: 300℃ (572℉), P3: 350℃ (662℉), P4: 400℃ (752℉), P5: 450℃ (842℉)
The initial number of active presets is set to 5 at the factory.
The default selected preset is set to P3 at the factory.
Example : Changing preset temperature from preset No.1(250℃) to No.3(350℃).
Heater control will begin with new preset temperature.
The procedure for making changes to the preset temperatures is the same with “A. Changing the set
temperature” in 5. OPERATION. Enter the parameter setting to change the mode. (Please refer to [6.

The HAKKO FX-889 has four parameters. Parameter settings can be set for A. IRON and B. IRON
respectively. Turn the power on while pressing the button (A.IRON or B.IRON). Perform the setting to select the
desired parameter No.. Press the button to change the values, and press the button to execute.

C. Performing the temperature adjustment
When replacing the iron, heater or tip, a temperature adjustment may be required.
Use adjustment mode to perform the temperature adjustment.
• Enter the observed value in the adjustment mode after the tip temperature stabilizes.
• The maximum single adjustment that can be made is ±150℃ (270℉) relative to the set temperature.
If a larger adjustment is needed, make the first adjustment at the maximum value of 150℃ (270℉),
then repeat the adjustment process.
• When a new soldering iron is used or insertion position is changed from A.IRON to B.IRON (and vice
versa), temperature adjustment is always required.
CAUTION
* How to distinguish between Temperature
Setting Mode and Adjustment Mode.
The display differs in the temperature setting
and the adjustment mode.

Please be sure to confirm the status of the
identification lamps so that you do not enter
a value in the wrong mode.
NOTE:
During adjustment mode, the hundreds digit will
accept values from 0 through 6 if the temperature
is set to display in ℃, or the values 0 through 9
if the temperature is set to display in ℉.
D. Restriction on setting changes (Password function)
It is possible to restrict certain setting changes to the unit.
There are three choices for the password setting. (The factory default is "0 : Open")
○: You can make changes without entering a password.
△: You can choose whether or not a password is needed to make changes.
×: A password is required to make changes.

7. MAINTENANCE
Since the soldering iron can reach a very high temperature, please work carefully. Except the case
especially indicated, always turn the power switch OFF and disconnect the power plug before performing
any maintenance procedure.
WARNING
CAUTION
Do not file the tip in an attempt to remove the black oxide.
7. MAINTENANCE
A. Using the cleaning sponge
Use the cleaning sponge that comes with the product to
clean the tip. It offers wide-ranging uses, from simple
removal of excess solder to complete elimination of matter
occurring as a result of oxidization.
B. Using the cleaning wire
Material that is not removed easily with the cleaning
sponge can likely be removed using the cleaning wire.
C. Using the rubber plate
Wipe the iron lightly across the rubber ring to remove
excess solder from the tip.
