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