Failure to do so may result in serious problems.
Be sure to save this screw.
When the power is on, the nozzle temperature will be between 350°C/662°F and 450°C/
842°F.
Mishandling may lead to
● Do not touch the metallic parts near the nozzle, nearby plastic parts and the 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 when no longer using the Hakko 472D or leaving it unattended.
● Before replacing parts or storing the unit, turn the power off and allow the unit to cool
to room temperature.
To prevent accidents and failures, be sure to take the following precautions:
● Do not use the unit for applications other than desoldering.
● Do not rap the desoldering iron against the workbench 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 with wet hands.
● Use the ceramic paper filter (S) for the filter retainer (station), and the ceramic paper
filter (L) for the filter pipe (iron/gun).
● Maintain the desoldering gun and the station.
● While using the unit, don’t do anything that could cause bodily harm or physical
damage.
burns or fire. Be sure to comply with the following precautions.

OPERATION
Heated solder and flux can cause oxides to
form and adhere to the nozzle and the inside
of the heating element. These oxides not only
lower the heat conductivity, but can also clog
the nozzle and heating element, resulting in
a drop in suction efficiency. Should there be a
noticeable drop in suction efficiency during
operation, replace the filter and clean the
nozzle and heating element with the
provided cleaning pin.
● PREPARATION FOR USE.
1. Attach the iron holder.
Remove the iron holder mounting screws
from the side of the station.
Attach the iron holder to the station.
(Figure 1 shows Hakko 807; figure 2
shows Hakko 817.)
(The iron holder can be installed on the
either the left or right side.)
(Figure 1)
(Figure 2)
CAUTION:
Be sure to use appropriate iron holder for 807 or 817.
Misuse may damage the desoldering iron/gun.
2. Attach the desoldering tool
Hakko 807 desoldering iron:
Insert the filter pipe (with a filter holder,
spring filter and ceramic paper filter (L))
into the housing.
Push and turn the back holder clockwise.
(Figure 3)
Hakko 817 desoldering gun.
The desoldering gun for Hakko 817
comes with the filter pipe installed. This
filter pipe includes the spring filter and
ceramic paper filter. No assembly is
required.
3. Connect the desoldering tool to
the station.
CAUTION:
Be sure the power switch is OFF (
connecting the desoldering iron cord. Failure to do
so may result in damage to circuit board.

OPERATION
● Setting up the station.
Factory settings: The Hakko 472D is shipped
with the following preset values:
Temperature scale
Low temperature alarm setting
Set temperature
● Control card
°F
120
750
Each Hakko 472D comes with a small card, which
inserts in the control slot in the front of the unit.
This card is used when entering data for the
process control functions. Any Hakko 472D card
can be used with any Hakko 472D soldering
station.
This card is used when a value is to be changed or
data are to be entered. The Hakko 472D will
operate normally with the card inserted. Remove
the control card to lock the data.
Plug the power cord into the power supply
and turn the power switch to ON (
).
● Setting/changing the
temperature.
1. Insert the card into the card slot in the
front panel of the station.
• The HUNDREDS digit in the display
begins to flash, indicating that the station
is in the temperature setting mode and
data can be entered.
2. Enter the HUNDREDS digit.
• Use the
desired value for the HUNDREDS digit.
For setting in degrees Celsius, either 3 or
4 can be selected. For settings in degrees
Fahrenheit, values between 6 and 8 can
be selected. When the desired value is
displayed, press the
or button to select the
button.
Example :
Change the temperature from 700°F to 840°F
Insert the card.
Press the or button.

4. Enter the UNITS digit.
• Use the
or button to select the
desired value for the UNITS digit. Any
value from 0 to 9 can be selected. When
the desired value is displayed, press the
button. This will store the temperature
setting in memory and display the temperature setting. Heater control begins.
Remove the card to lock the data. The
temperature setting may not exceed
450°C (842°F). If a temperature above
this limit is entered, the HUNDREDS digit
begins to flash again after entering the
last digit. Follow step 2 - 4 again with a
temperature setting below 842°F (450°C).
NOTE:
If the power switch is turned off, or power is lost
during the execution of this procedure, no data will
be entered. The entire procedure must be repeated
from the beginning.
Press the button once.
Press the button once.
When the station is ON ( ) and
the card is in the station, the data
entry procedure follows:

1. Hold the button down for at least one
second.
2. The current temperature setting will be
displayed, then the HUNDREDS digit will begin
to flash. This indicates that the station has
entered the temperature setting mode.
3. Continue with the procedure of 2-4 above.
OPERATION
● Desoldering
1. Set the temperature. See
preceding section.
NOTE:
Always set the temperature as low as possible for the
work being done.
The temperature can be adjusted between 350 450°C (662 - 842°F).
2. Clean the tip of the nozzle.
Keep the tinned section of the nozzle
clean and shiny by coating it with a small
amount of solder.
If the tip of the nozzle is coated with oxide,
the nozzle’s heat conductivity will be
lowered. Coating the tip with a small
amount of fresh solder ensures maximum
heat conductivity.
NOTE:
Holder and sponge are not included with the Hakko 472D.
3. Melt the solder.
Sponge (Optional parts)
Wipe away any oxide or old solder
from the nozzle using the hole in
the center of the sponge.
Nozzle
P.W.B.
Solder
Lead
• Apply the nozzle to the soldered part and
melt the solder.
NOTE:
Never allow the nozzle to touch the board itself.
• Confirm that the solder is melted.
NOTE:
• To confirm that all the 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 the lead does not move easily, the solder has not
fully melted.
4. Extract the solder.
After confirming that the solder is
completely melted, extract the solder by
pushing the button on top of the 807
desoldering iron, or pressing the trigger
switch on the 817 desoldering gun.
NOTE:
Never leave any solder remaining inside the hole in
the P.W.B.
5. Problems during desoldering.
If solder remains, resolder the component
and repeat the desoldering process.
Slowly move the
lead with the nozzle.
Extract the solder by slowly
moving the lead back and
forth with the tip of the nozzle
whilst holding the button or
trigger.
