4. Operation
Desoldering
After turning the power switch to ON,
wait 3 minutes before begin-
ning desoldering operations.
1 Set the temperature.
CAUTION
Always set the temperature to as low
as possible for the work being done.
• To more precisely set the temper-
ature, measure the temperature
at the nozzle using a soldering
iron thermometer and adjust the
temperature control knob accord-
ingly.
We recommend the HAKKO FG-100
thermometer or HAKKO FG-101
soldering tester for measuring the
nozzle temperature.
• The temperature control knob
can be secured by tightening the
temperature control set screw
clamp (“+” screw) at the top of the
HAKKO 475 unit.
2 Clean the tip of the nozzle.
• Keep the solder-plated section
of the nozzle a shiny white by
coating it with a small amount of
solder.
If the tip of the nozzle is coated with
oxide, the nozzleʼs heat conductivity
will be lowered.
Coating the tip with a small amount
of fresh solder ensure maximum
heat conductivity.
Lock
Unlock
Secure the temperature
control set screw clamp
with a cross point screw-
driver.
Wipe away any oxide or old solder
from the nozzle using the hole in the
center of the sponge.
The temperature can be adjusted between 380°C (716°F)
and 480°C (896°F) with temperature control knob.
Please refer to the chart below, and adjust the tempera-
ture control knob.

3 Melt the solder.
• Apply the nozzle to the soldered
part 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.
CAUTION
Never move the lead by force. If it
doesnʼt move easily, the solder isnʼt
yet fully melted.
4 Absorb the solder.
• After confirming that the solder
is completely melted, absorb the
solder by squeezing the trigger on
the gun.
CAUTION
Never leave any solder remaining
inside the hole in the P.W.B.
• After fully absorbing all the solder,
cool the soldering junction in
order to prevent it from becoming
resoldered.
5 Problems during
desoldering.
• If solder remains, resolder the
component and repeat the desol-
dering process.

4. 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, result-
ing 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.
Cleaning during Operation
1 Observing the indicator
While looking at the indicator
and with the hole of the nozzle
open, pull the trigger and look
at the indicator. If it is red, clean
the nozzle and heating element,
empty the filter pipe, and replace
the filters. If the indicator is blue,
cleaning is not necessary and
operations can be resumed.
CAUTION
The indicator will not operate ac-
curately if the hole of the nozzle is
closed or if the solder in the hole of
the P.W.B. is not melted.
CAUTION
The indicator on the HAKKO 474
reads in a different way.
For instruction on the reading the
HAKKO 474 indicator, please refer to
the HAKKO 474 instruction manual.
2 Replacing the filter
Replace the filter as shown A to C.
During operation, the filter pipe is
very hot. Wait until the filter pipe
is cool before replacing the filter.
We recommend keeping a second
filter pipe containing new filters
handy, and replacing the installed
filter pipe with this backup filter
pipe.
A Replace the entire filter pipe
with he provided backup filter pipe. B Pull
C Down
Normal
One-half or
less of rthe
indicator is red.
Abnormal
Three-fourths
of the indicator
is red.
Solution
If three-fourths or more of
the indicator is red, replace
the filter and clean the
nozzle and the inside of
the heating element.
(refer to p.12 Maintenance
of the Desoldering Gun)
CAUTION : If there is a noticeable drop in suction
efficiency, clean the nozzle and heating ele-
ment with the cleaning pin.
