OPERATION

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:

The cleaner is not included.

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 it doesn’t move easily, the solder is not yet fully
melted.

Nozzle cleaner (Optional parts)

Wipe away any oxide or old solder
from the nozzle using the hole in
the center of the sponge.

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 the iron usage.
During maintenance, please wear gloves and work carefully.

WARNING:

Since the desoldering iron 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.

• 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 and cleaning drill do not
pass through the hole in the nozzle,
replace the nozzle.

Cleaning with the nozzle cleaning pin.

The cleaning pin passes
completely through the hole.

Cleaning with the cleaning drill (option).

• Before cleaning

Insert the bit while turning it clockwise.

• After cleaning

Pull the drill bit out straight without turning it.

CAUTION
If the cleaning drill is forced
into the nozzle, the drill bit

could break or be damaged.

CAUTION
Please use the proper sized
cleaning pin or cleaning drill
for the nozzle diameter.

NOTE:

Unfortunately, it is often diffi­cult to observe this condition,
therefore, if desoldering effi­ciency goes down and all
other parts appear to be OK,
the nozzle is probably eroded
and should be replaced.

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 “Trouble Shooting 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 iron 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°C – 50°C = 350°C (750°F – 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.
