Instruction Manual
●
Thank you for purchasing the FM-2024 desoldering tool.
Please read this manual before operating the FM-2024.
Keep this manual readily accessible for reference.
●
CAUTION
● The FM-2024 cannot function by itself. It must be connected to
the Desolder Control Box (DCB), which in turn connects to the
soldering station of choice, either FM-202 or FP-102.
● For detailed information on the FM-202 and the FP-102 soldering
stations, refer to the instruction manual for the appropriate
soldering station.

3. WARNINGS, CAUTIONS AND NOTES
WARNING
In this instruction manual, “WARNING” and “CAUTION” are defined as follows.
WARNING: Misuse may potentially cause death of, or serious injury to the
user.
CAUTION : Misuse may potentially cause injury to the user or physical
damage to the objects involved.
For your safety, be sure to comply with these precautions.
Failure to do so may result in serious problems.
CAUTION
When the power is on, the nozzle temperature is between 650°F/350°C and 840°F/450°C.
Since mishandling may lead to burns or fire, be sure to comply with the following
precautions.
● Do not touch the metal parts near the nozzle, nearby plastic parts, or the spring iron
holder.
● Do not use the product near flammable items.
● Advise other people in the work area that the unit can reach a very high temperature
and should be considered potentially dangerous.
● Turn the power off while taking breaks and when finished using the unit.
● Before replacing parts or storing the unit, turn the power off and allow the unit to cool to
room temperature.
To prevent damage to the unit and ensure a safe working environment, be sure to comply
with the following precautions.
Use only filtered air. Adjust the pressure to 490 to 686 kPa (5.0 to 7.0 kgf/cm2) while
allowing air to flow by pulling the trigger.
● Do not use the unit for applications other than desoldering.
● Do not rap the desoldering tool against the work bench to shake off residual solder, or
otherwise subject the iron to severe shocks.
● Do not modify the unit.
● Use only genuine HAKKO replacement parts.
● Do not wet the unit or use the unit when your hands are wet.
● When desoldering, ensure good ventilation for smoke.
● While using the unit, don’t do anything which may cause bodily harm or physical dam-
age.

Assembling, connection and
operation
1. Iron holder
2. Connecting and replacing
the filter pipe
Pull the back holder (A) 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.
3. Attaching and replacing
the nozzle
Insert the grip fully into the
nozzle cartridge as shown in
the illustration. Once the nozzle
cartridge is inserted, it is locked
automatically.
To replace the nozzle cartridge,
insert the nozzle remover into the
flange of the nozzle cartridge and
pull.

CAUTION
The nozzle can be very hot. To attach or
remove the nozzle cartridge, be sure to
use the nozzle remover to preclude the
possibility of breaking the grip or cartridge.
CAUTION
The surface of the filter pipe
assembly may be very hot.

5. OPERATION
Press the nozzle unlock button (A)
and 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.
Connections
1. Connect the plug from the
FM-2024 to the receptacle on the
DCB, then connect the DCB to
the soldering station as shown in
the drawing.
2. Put the FM-2024 into the iron
holder
To mount the FP-102 atop the
DCB, attach two rubber feet,
which come with the FP-102, to
the bottom rear of the FP-102 to
prevent the FP-102 from falling
off.
3. Connect the hose from the
FM-2024 to the filter case cover
on the DCB.

4. 4. Connect the DCB to the shop
air supply/compressor.
Use only filtered air to eliminate
the probability of dust, water,
and oil content from fouling the
mechanism.
Adjust the pressure to 490 kPa
(5.0 kgf/cm2) with the regulator
while allowing air to flow by
pressing the button (or pulling the
trigger) on the handpiece.
CAUTION
If you attempt to adjust the pressure
without allowing air to flow, or if the
tube size is not as specified, the
suction capability will decrease.
Ensure that the regulator shows less
than 882 kPa (9.0 kgf/cm2) when the
trigger is turned OFF. If pressure equal
to or higher than this value is applied,
damage may result.
5. Turn ON the power
Ensure that the power switch is
OFF before inserting the AC plug.
CAUTION
Be sure to ground this product as it is
ESD safe by design.
Turn the power switches ON as
follows: First, the DCB; second,
the soldering station. Unless
the DCB is turned on first, an
error message will appear since
the desoldering iron remains
disconnected.

Operation
1. When the FM-2024 is used with
the FM-202, turning the power
switch ON will display the nozzle
ID .
All the standard nozzles for
FM-2024 share the same ID .
Use the standard nozzle as it is.
If a different ID was entered,
change to . Refer to the
FM-202 instruction manual for
instructions in changing the
nozzle ID.
2. Set the temperature.
Refer to the instruction manuals
for the soldering station being
used.
3. Reaching the set
temperature
After the soldering station has
reached the set temperature,
there will be an idle period of 15
seconds before the 'ready' alarm
sounds. This time is used to
ensure more efficient suction.
For the FM-202, pressing the
push button (or pulling the trigger)
before the alarm sounds will cause
the displayed temperature to start
blinking. Neither model should
be used until after the alarm has
sounded. However, if the nozzle
temperature is 482°F/250°C or
higher when the power is turned
ON, the idling time will be omitted.
Removing solder
Clean the nozzle end.
Be sure the nozzle tip is tinned
with clean, fresh solder.
CAUTION
In case of long shape nozzle, the nozzle temperature will be lower
than the normal one. In order to set very precise temperature,
enter the nozzle ID number of .

FM-2024 24V-70W
If the nozzle tip is coated with
oxidized film or the like, its thermal
conductivity deteriorates. In contrast,
if the nozzle end is wetted with a
small amount of clean solder, its
thermal conductivity increases.
1. Melt the solder.
Position the nozzle above the
lead to be desoldered as shown
in the illustration and melt the
solder.
CAUTION
Never allow the nozzle to touch the
board itself.
Confirm that the solder is melted.
CAUTION
To confirm that all solder is melted,
observe the inside of the hole and
the backside of the P.W.B. If this
is difficult to do, try slowly moving
the lead with the nozzle. If the lead
moves, the solder is melted. Never
move the lead by force. If it doesn’t
move easily, the solder isn’t yet fully
melted.
2. Extract the solder.
After confirming that the solder
is completely melted, extract the
solder by pressing the button (or
squeezing the trigger)
CAUTION
Never leave any solder remaining
inside the hole in the P.W.B.
3. Problems during
desoldering.
If solder remains, resolder the
