Daily check for desoldering tool

For using a desoldering tool in good condition, it is recommended to conduct a daily check after every use and aperiodic inspection depending on the frequency of usein a correct way.

How to conduct a daily check after every use * In case of FR-410

Conduct daily check after use keeping the nozzle heated.
Ensure to wear gloves not to get burned due to high temperature.

1. Turn on the power switch and let the nozzle heat up.

2. Clean out the hole of the nozzle.

   

   You cannot conduct cleaning if inside the heating element is not heated enough.

   Insert the cleaning pin for nozzle into the nozzle top and check if it goes through the heating element hole.

   

   Clean the nozzle hole with a cleaning drill if the cleaning pin does not go through.

   Insert the cleaning drill while turning it clockwise, and pull it out straight without turning.

   

   

3. If the nozzle cleaning pin does not go through the heating element hole after cleaning out the nozzle hole, clean the heating element hole, disassembling the nozzle and enclosure pipe.

   1. Cover the nozzle and the enclosure pipe with the nozzle wrench.

   

   2. Detach the nozzle and the enclosure pipe while turning left the nozzle wrench.

   

   

   3. Put the detached nozzle and the enclosure pipe on the tray of the iron holder.

   

   4. Insert the cleaning pin (for heater) into the heating element hole and clean its inside.

   

   You cannot conduct cleaning if inside the heating element is not heated enough.

   Replace the heating element if the cleaning pin (for heater) does not go through the heating element hole.

   5. Set the nozzle and the enclosure pipe to the nozzle wrench after cleaning.

   

   6. Attach the nozzle and the enclosure pipe while turning right the nozzle wrench.

   

4. Measure the nozzle temperature with the thermometer.

   

   If the set temperature does not match the nozzle temperature, the adjustement of temperature(Changing the offset value or CAL adjustement) is required.

   Methods for temperature adjustment depend on the product.

   Check the product's instruction manual, referring to the offset setting or temperature correction information.

5. Cover the nozzle with the solder after check to prevent it from oxidizing.

   

   Confirm that the nozzle is covered with the solder and see if it showed ideal wetting and spreading of solder.
