A. Iron holder
●Operation
First, remove any excess solder from the tip by
thrusting the tip into the cleaning wire. (Do not
wipe the tip against the wire. This may cause
molten solder to spatter.)
1. Insert the holder assembly securely into the
Iron holder base.
2. When the wire becomes dirty or loaded with
solder, turn the wire until a clean surface is
presented.
3. When changing the cleaning wire, lift the case
top vertically to prevent solder debris from
falling out.
4. Place the spare tips in the tip tray.
●Use of the sleep function
When using the sleep function, insert one end of
the connecting cable into the jack at the back of
the iron holder and the other end into the jack at
the back of the desoldering station to connect
them.
CAUTION
• Be sure to turn off the power before connecting or
disconnecting the connecting cable.
• Securely insert the relay cord all the way into the jack.
B. MODEL FM-2024
●Connecting and replacing the filter pipe
Pull the back holder until it locks, then
insert the filter pipe assembly with the opening
to the nozzle side. Ensure that the outer
surface of the filter pipe assembly is even with
the handle support. If the filter pipe assembly
is tilted, a leak may occur.
To replace the filter pipe assembly, press back
holder unlock button , pull the back holder
to lock it, change the filter pipe assembly, then
lock the filter pipe assembly. Replace the filter
pipe assembly in the cartridge.

remover into the flange of the nozzle cartridge,
press the nozzle unlock button Aand remove
the nozzle cartridge.
CAUTION
The nozzle may be very hot.
The nozzle remover may be left mounted on
the end of the straight grip when not in use to
prevent it from being misplaced.
●Using the desoldering iron in the gun
configuration.
To use the desoldering iron in the gun
configuration, attach the handle to the straight
grip.
●Using the desoldering iron in the pen
configuration.
To remove the handle, slide down the button
located on the rear of the handle to unlock it,
then slide the handle toward the back of the
MODEL FM-2024.
Inserting the tip:
●Holding the front end of the tip, insert it into
the sleeve assembly.
CAUTION
Insert the tip into the sleeve assembly until it clicks into
place. When you hear it clicks, avoid forcing the tip into the
sleeve assembly.
●Insert the tip securely into the connector.
NOTE:
Improper insertion of the tip will cause to appear
on the display.

C. Desoldering station
CAUTION
• Be sure to unplug the cord by holding the plug.
• Securely insert the connecting cable all the way into the jack.
●The HAKKO FM-204 detects when the iron is
removed from the iron holder and sends this
data to the station via the connecting cable.
That data is then used for various functions.
●Connection
1. Connect the power cord to the inlet on the
rear of the station.
(Connect the plug from the MODEL FM-2024
to the receptacle on the HAKKO FM-204.)
The HAKKO FM-204 can be used without being
connected to a control box.
CAUTION
Connect the plug to the receptacle, aligning the tab on the
plug with the opening on the receptacle.
2. Put MODEL FM-2024 into the iron holder.
3. Connect the hose from the MODEL FM-2024
to the filter case cover on the HAKKO FM-204
Station.
4. Plug the power cord into a grounded wall
socket.
Ensure that the power switch is OFF before
inserting the AC plug.
Turn the power switches ON.
CAUTION
Be sure to ground this product as it is ESD safe by design.
5. Turn ON the power.
CAUTION
The HAKKO FM-204 does not function properly if the
power is turned on with the trigger pressed. Release the
trigger and then turn the power ON.

Error .................. Blinks quickly
Operation
1. Turn the power switch ON.
2. By default, when the set temperature is
reached, the buzzer sounds, indicating that
the unit is ready.
The heater lamp on the front panel starts
blinking.
5. OPERATION
Displays
The HAKKO FM-204 has a three-digit display
element.
Depending on the selected mode, it will display:
●Sensor temperature (of the iron tip)
●Data entry:
Selected quantity (See the data entry
procedures.)
●Temperature scale:
ºC or ºF, depending on selection
●Error detection (See ERROR MESSAGES.)
An audible buzzer is provided to alert the
operator:
●When the station has reached the set
temperature, the buzzer will sound once.
(Default setting)
●When the low temperature threshold has been
crossed, the buzzer will sound continuously.
This buzzer will shutoff when the sensed
temperature returns to the acceptable range.
●When a foreign substance, an incompatible
tip, or the soldering end of the tip is inserted
into the HAKKO FM-2027, the display will
blink and the buzzer will sound continuously.
●When the auto-power shutoff function is
activated and power to the heater is shut off,
the buzzer sounds three times.
CAUTION

Changing the temperature setting
• MODEL FM-2024
Temperature setting range
ºC................350 to 450ºC
ºF ................660 to 840ºF
• HAKKO FM-2027 (Option)
Temperature setting range
ºC................200 to 450ºC
ºF ................400 to 840ºF
Example: Changing the temperature from
350ºC to 400ºC
1. Insert the control card into the station.
●The hundreds digit of the display begins to
flash. This indicates that the unit has entered
the temperature setting mode and data may
be entered.
2. Enter the hundreds digit.
●Press the or button to set the
hundreds digit. When the desired figure is
displayed, press the button. The tens digit
begins to flash.
3. Enter the tens digit.
●Press the or button to set
the tens digit. When the desired figure is
displayed, press the button. The units
digit begins to flash.
4. Enter the units digit.
●Set the desired units digit in the same way
as for the tens digit, and then press the
button. The temperature is recorded to the
internal memory, and heater control begins
after the new set temperature is displayed.
To change the set temperature with
the control card in the station:
NOTE:
If you enter a value outside the temperature setting range
(see the table above), the display returns to the hundreds
digit, and you have to enter a correct value.
CAUTION
If the power is turned off without completing the
temperature setting, the new set temperature will not
be recorded.
1. Press and hold the button for at least one
second. The current temperature setting is
displayed, and then the hundreds digit begins
to flash one second later. This indicates that
the station has entered the temperature
setting mode.
Follow steps 3 to 4 on “Changing the
temperature”.
2. If the button is not pressed and held for at
least one second, the current set temperature
is displayed, and then the tip temperature is
displayed.

●Entering the tip offset value
Example:
When the set temperature is 400ºC and
the actual tip temperature is 410ºC: The
difference in temperature is 10ºC, so enter
–10 as the current offset value.
1. Insert the control card into the station.
●
The station enters the temperature setting mode.
2. Press the button.
●The station enters the offset entry mode.
Press the or button to set the
hundreds digit.
The values that can be entered in ºC or ºF are 0
(for positive values) and - (for negative values).
3. Select or and press the
button.
The tens digit begins to flash. Enter the offset
value.
The values that can be entered to the tens
digit are 0 to 5 in ºC (0 to 9 in ºF).
The tens and units digits are set with the
offset value range.
Allowable offset value range
ºC................. –50 to +50ºC
ºF ................. –90 to +90ºF
If you enter a value outside the allowable
offset value range, the display returns to
the hundreds digit, and you have to enter a
correct value.
CAUTION
In the offset entry mode (when the display is flashing), the
tip temperature is controlled by the current offset value.
4. Verify the tip temperature.
Press the button once.
Press the or button.
Press the or button.
Press the button once.
Press the button once.
Press the button once.
NOTE:
The station stores the offset values for each tip type.
For example, connect the HAKKO FM-2027 to the
station and enter the offset value (–10ºC). Next, change
to the MODEL FM-2024 and enter the offset value
–20ºC). When you reconnect the HAKKO FM-2027, the
offset value is set to –10ºC automatically.
The temperature accuracy of iron tips is ±15°C (±27°F) (except for designated tips) when using the default offset
values. If a higher temperature accuracy is required, use the following offset function:
