2. Безбедносна упутства
УПОЗОРЕЊЕ: Непоштовање ових безбедносних упутстава може довести до струјног удара, пожара или озбиљних повреда.
- Always wear appropriate personal protective equipment, including safety glasses, when operating the soldering iron.
- Ensure the work area is well-ventilated to avoid inhaling solder fumes. Use a fume extractor if possible.
- Do not touch the soldering iron tip or heating element when the iron is powered on or cooling down, as temperatures can reach up to 480°C (896°F).
- Увек стављајте лемилицу у њен предвиђени сталак када се не користи.
- Држите лемилицу даље од запаљивих материјала.
- Не користите лемилицу у близини воде или уamp условима.
- Искључите лемилицу из утичнице када је не користите или пре него што извршите одржавање.
- Do not modify the soldering iron or use it for purposes other than soldering.
- Чувати ван домашаја деце.

- Прикључак за напајање: Укључите кабл за напајање у одговарајућу електричну утичницу.
5. Упутство за употребу
- Укључено: Flip the Master Switch to the "ON" position. The LED digital display will illuminate.
- Подешавање температуре:
- Користите Up и Доле arrow buttons to adjust the desired temperature. The temperature range is typically 90°C to 480°C (194°F to 896°F).
- The iron heats rapidly, reaching 300°C in approximately 18 seconds.

Image: Close-up of the LED digital display showing temperature in Celsius and Fahrenheit, demonstrating the C/F conversion feature and high accuracy.
- Celsius/Fahrenheit Switching:
- To switch between Celsius (°C) and Fahrenheit (°F), press and hold both the Up и Доле arrow buttons simultaneously for a few seconds until the unit changes.
- Интелигентна функција спавања:
- The soldering iron features an intelligent sleep function (0-99 minutes). If the iron remains static for the set sleep time, its temperature will automatically drop to 90°C to save energy and prolong tip life.
- To wake the iron from sleep mode, gently shake it. The iron will quickly return to its previously set operating temperature.

Image: Illustration of the intelligent sleep function, showing the display indicating "SLP" and the iron resting in its stand. A hand is shown gently shaking the iron to awaken it.
- Корекција температуре:
- If the displayed temperature deviates from the actual tip temperature, a temperature correction function is available. Refer to the full product manual or manufacturer's webсајт за детаљне кораке калибрације.
- лемљење: Once the desired temperature is reached, the iron is ready for use. Apply solder to the joint, not directly to the iron tip.
- Искључивање: When finished, turn off the Master Switch and unplug the iron. Allow it to cool completely in its stand before storing.
6. Одржавање
- Чишћење савета: Редовно чистите врх за лемљење помоћу адamp sponge or brass wool. This helps prevent oxidation and ensures efficient heat transfer.
- Калајисање врхова: After cleaning and before storage, apply a small amount of solder to the tip (tinning) to protect it from oxidation.
- Замена врха: Replace the soldering tip when it becomes excessively worn or corroded. Ensure the iron is cool and unplugged before changing tips.
- Генерално чишћење: Обришите тело лемилице меком, сувом крпом. Не користите абразивна средства за чишћење или раствараче.
- Складиштење: Store the soldering iron in a dry, safe place, away from dust and moisture, and out of reach of children.
