· For volume desoldering, the
temperature control knob can
be secured by tightening the
temperature control knob
securing screw ("+ " screw) at
the top of the HAKKO 475 unit.

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
nozzle's heat conductivity
will be lowered.
Coating the tip with a small
amount of fresh solder
ensures maximum heat
conductivity.

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

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 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.

CAUTION

Never move the lead by force. If it
doesn't move easily, the solder isn't
yet fully melted.

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 junc­ tion in order to prevent it from
becoming resoldered.

Problems during
desoldering

·If solder remains, resolder the
component and repeat the
desoldering process.

Absorb the solder by slowly
moving the lead back and
forth with the tip of the
nozzle.

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.

Cleaning during Operation

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 accurately
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 instructions on the reading the
HAKKO 475 indicator, please refer to
the HAKKO 475 instruction manual.

Replacing the filter

Replace the filter as shown
. 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.

Normal Abnormal Solution

If the indicator is more
than half red, replace
the filter and clean the
nozzle and the inside

Blue or slight
amount of red
can be seen.

CAUTION :

Replace the entire filter pipe
with the provided backup filter pipe.

More than half
of the indicator
is red.

If there is a noticeable drop in suction
efficiency, clean the nozzle and heating
element with the cleaning pin.

Problems during Desoldering

A. The solder in the junction
is not sufficiently melted.

B. Suction power is dropping.

A. The solder in the junction is not sufficiently melted.

Temperature is not high enough.

The following parts require a greater heat capacity to
desolder.

·Multilayer P.W.B.s, power supplies, ground planes in
through-hole P.W.B.s, high-capacity transistors, triacs
with heat radiation fins, tuner P.W.B. ground wires,
and large-scale transformer terminals.

Use a preheating oven or heating gun to heat the P.W.B. to
a temperature that won't damage the board or its compo­nents [between 70˚C (160˚F) and 80˚C (180˚F)], then desol­der. Do not increase the temperature of the gun by recalibra­tion as this may damage the P.W.B. and its components.

Nozzle is worn out.

·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.
(refer to p.12)

B. Suction power is dropping.

·Replace the filters, and clean the nozzle and the inside
of the heating element. (refer to p.12~16, Maintenance
of Desoldering Gun and Station )

(Desoldering Gun)Maintenance

Properly maintained, the HAKKO 475 desoldering gun should provide years of good service.
Efficient desoldering depends upon the temperature, and the quality and quantity of the solder
and flux. Perform the following service procedures as dictated by the conditions of the gunÕs usage.

WARNING :

Since the desoldering 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 Gun

CAUTION

The desoldering gun will be extremely hot.
During maintenance, please wear gloves
and work carefully.

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.

CAUTION

The cleaning pin will not pass through
the nozzle until the solder inside the
nozzle is completely melted.

· If the cleaning pin does not
pass through the hole in the
nozzle, clean with the cleaning
drill.

· Check the condition of the
solder plating on the tip of the
nozzle.

· If it is slightly worn, recoat the
tip with fresh solder to prevent
oxidation.

· Check the condition of the
surface and inside hole of the
nozzle.

· If either is worn or eroded, or
the inside diameter seems
unusually wide, replace the
nozzle.

CAUTION

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.

Condition of Measurement

· Insulation Resistance

The insulation resistance was measured between the nozzle and the lead of the heating element using a 500 V DC insulation resistance meter.

Caution: The insulation resistance cannot be measured between the nozzle and the power plug as the transformer between the secondary part (heating element) and the primary part acts as an insulator.

· Voltage Leakage

The voltage leakage was measured between the nozzle and the grounding plug at a temperature of 480˚C (896˚F) using an AC mV meter.

Caution: Be sure to ground the unit before measuring the the voltage leakage.

· Specifications are subject to change without notice.
