Mishandling may lead to burns or fire. Be sure to comply with the following precautions.
●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).

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.)
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 ( ) before connecting the desoldering iron cord. Failure to do so may result in damage to circuit board.
•Connect the cord assembly of the desoldering tool (Hakko 807 or 817) to the receptacle on the station (see Figure 4).
•Connect the hose to the vacuum outlet cap. (Figure 5)
•Set the tool in the iron holder. (Figure 6 and 7)

(Figure 1)
(Figure 2)
CAUTION:
Be sure to use appropriate iron holder for 807 or 817. Misuse may damage the desoldering iron/gun.
(Figure 3)
VACUUM
Attach the hose securely over the vacuum outlet cap.
(Figure 5)
Insert the cord assembly by keying the plug to the key on the receptacle.
Secure the plug by turning it clockwise.

OPERATION
● Setting up the station.
Factory settings: The Hakko 472D is shipped with the following preset values:
Temperature scale |
°F |
|
|
Low temperature alarm setting |
120 |
|
|
Set temperature |
750 |
|
|
● Control card
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 
or 
button to select 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 
button.
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.
Example :
Change the temperature from 700°F to 840°F
Insert the card.
Press the UP or DOWN button.
Press the 
button once.

OPERATION
3.Enter the TENS digit.
•Press the 
or 
button to select the desired value for the TENS digit. Any
value from 0 to 9 can be selected. When
the desired value is displayed, press the 
button. The UNITS digit begins to flash.
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 UP or DOWN button.
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.
•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.
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
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.
