10 / 24 page 9 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. |
