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 471 reads
in a different way.
For instructions on the reading the
Hakko 471 indicator, please refer to
the Hakko 471 instruction manual.
CAUTION
If there is a noticeable drop in suction
efficiency, clean the nozzle and heating
element with the cleaning pin.
CAUTION :
Normal
Abnormal
Solution
Blue or slight
amount of red
can be seen.
More than half
of the indicator
is red.
If the indicator is more
than half red, replace
the filter and clean the
nozzle and the inside
of the heating element.
(refer to p.12
Maintenance of the
Desoldering Gun)
Replace the entire filter pipe
with the provided backup filter pipe.
Cleaning during Operation
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.
Observing the indicator
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.

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.
