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.

Problems during desoldering 1. The solder in the
junction is not sufficiently melted.
2. The nozzle is worn out.
3. Suction power is dropping.
4. Air is leaking from the vacuum system.
Post-operation maintenance.
To ensure a long service life, always perform the following maintenance procedures immediately after using the Hakko 472D unit.

· Temperature is not high enough. Many assemblies require a greater heat capacity to desolder, including multilayer P.W.B.s, power supplies, ground planes in through-hole P.W.B.s, highcapacity transistors, triacs with heat radiation fins, tuner P.W.B. ground wires, and large-scale transformer terminals.
Use a pre-heater, such as the Hakko 853, or other heat source to heat the P.W.B. to a temperature between 70-80°C. (160180°F.) that will not damage the board or its components, then desoldering. Do not increase the temperature of the gun by recalibration as this may damage the P.W.B. and its components.
· When the nozzle begins to wear out, the heating efficiency begins to decline. Check the nozzle. If the solder plating is damaged, or the nozzle is eroded, replace the nozzle.
· Replace the filters, and clean the nozzle and the inside of the heating element, as described in the section on maintenance.

Check the air-tightness of the following parts and replace any that are worn.

a. Contact point of the nozzle and heating element. (for Hakko 807 & 817)
b. Front holder and nearby parts. (for Hakko 807 & 817)

c. O-ring in the back holder (for Hakko 817 only)
d. Hose (for Hakko 807 & 817)
e. Vacuum outlet cap (for Hakko 807 & 817)
f. Packing and nearby parts (for Hakko 817 only)

NOTE: Air leakage cannot be determined from the indicator (for Hakko 817 only)

Remove all solder from the inside of the nozzle and heating element. Refer to MAINTENANCE, p.12.
Clean the tip of the nozzle with the cleaning sponge, then coat the tip with a fresh layer of solder to protect the solder plating.

MAINTENANCE
Efficient desoldering depends upon the temperature, the quality and quantity of the solder and flux. Perform the following service procedures as dictated by the conditions of use. During maintenance, please wear gloves and work carefully.
WARNING: Since the desoldering iron/gun can reach a very high temperature, please work carefully. Except when cleaning the nozzle and heating element, always turn the power switch off and disconnect the power plug before performing any maintenance procedure.

Servicing the Desoldering iron
1. Inspect and clean the nozzle.
· Plug in the power cord, turn the power switch “ON” and let the nozzle heat up.
· Clean out the hole of the nozzle with the nozzle cleaning pin. If the nozzle cleaning pin does not pass through the nozzle, use the cleaning drill (option).
NOTE: · The cleaning drill is not included. · The cleaning pin will not pass through the nozzle
until the solder inside the nozzle is completely melted. · Verify that the correct cleaning pin is used for the nozzle. The inside diameter of the nozzle is stamped on the side of the nozzle.
· Check the condition of the solder plating, surface and inside hole of the nozzle. If it is slightly worn, recoat the tip with fresh solder.
· If it is worn or eroded, or the inside diameter seems unusually wide, replace the nozzle.
NOTE: The inside hole and the surface of the nozzle is plated with a special alloy. Should this alloy become eroded by high temperature solder, the nozzle will not be able to maintain the proper temperature.
· If the cleaning pin or cleaning drill do not pass through the hole in the nozzle, replace the nozzle.

WARNING: Unplug the power cord before starting this procedure.
Check the resistance value The resistance values of a working heating element are 9.2 between pins 1 and 3 (heating element), 54 between pins 2 and 4 (sensor) at 73°F (23°C). If the measured values are outside this range, replace the heating element. (No.A1507 24V-60W heating element for Hakko 817)
Replacing the heating element. 1. Unplug the cord. 2. Remove the nut, element cover and nozzle. 3. Remove the screws securing the heating
element to the housing. 4. Remove the screws securing the housing
and separate the housing. 5. Remove the packing. 6. Detach the terminal. 7. Remove the old heating element and
replace it with a new one. 8. Reassemble the unit.
CAUTION: Be sure to place the packing to prevent air escaping. Failure so to do will cause a loss in suction.

Replacing the cord (For Hakko 807 and 817)
Test method 1
1. Turn the unit on. 2. Set the temperature to 450°C (842°F). 3. Before the iron/gun reaches the set
temperature, wiggle the cord at various points along the length of the cord, including in the strain relief area at the base of the iron/gun housing. If the heater lamp flickers, the cord is broken and should be replaced.
Test method 2
Check the resistance between each pin on the connecting plug and its associated wire on the terminal board inside the housing. All measured vales should be 0. If any value is greater than 0, replace the cord.
Recalibrate the temperature
(a) Set the desired temperature. (b) Adjust the temperature calibration pot
(CAL) until the nozzle temperature (measured with a thermometer) is correct.
CAUTION: Never set the nozzle temperature above the maximum temperature. It will cause problems.

CAUTION: The heater lamp will flicker if the iron/gun temperature is allowed to reach the set temperature. Before replacing the cord, be sure that this is not the reason for the flickering.

ERROR MESSAGES
Various error messages will be displayed when there is a problem with the Hakko 472D unit. If the following message is displayed, refer to “TROUBLESHOOTING GUIDE”.

System Error Sensor Error
Low temperature tolerance
(Flashing of the temperature display)

After the power has been turned on, the system

checks the memory and the programs. If an

abnormality is found,

will be displayed, and

all operations will be completely stopped.

If there is a possibility of a failure in the sensor or

anywhere in the sensor circuit,

will be

displayed and power to the desoldering iron will be

cut off.

The sensor error also occurs if the cord assembly

is not properly connected.

If power is present at the desoldering tool and the nozzle temperature goes below the heater error temperature tolerance setting, the temperature display will flash. This indicates the possibility of a heater malfunction.

EXAMPLE: Assume the temperature setting is 400°C (750°F) and the low temperature tolerance is 50°C (100°F). If, even though the heater is receiving power, the temperature of the desoldering iron goes below 350°C (650°F) the display will begin to flash, indicating a possible heater malfunction.

EXAMPLE: 400 50°C = 350°C; (750 100°F = 650°F) The display will begin to flash.

NOTE: If the temperature begins to rise again, the display will stop flashing even if the displayed temperature is below 350°C (650°F).

BEFORE SERVICING ……
WARNING: · Disconnect the power plug before servicing.
Failure to do so may result in electric shock. · If the power cord is damaged, it must be replaced by the manufacturer, its authorised
service agent, or a similarly qualified technician to avoid hazard. 19
