the plug from the power outlet.

Failure to observe the following precautions to ensure safety might result in electric shock, malfunction or other

trouble.

● Before using this product, fully read all descriptions in this document.

● Only use the product for soldering.

● Do not hit the handpiece against a workbench or subject it to strong shocks to remove solder residue.

● Soldering produces smoke, so make sure to work in a well-ventilated area.

● Use genuine HAKKO parts for included parts/replacement parts/options.

● Do not modify this product.

● Do not use damaged cords or plugs. Doing so can result in malfunction or injury.

6. Maintenance

CAUTION

Do not file oxidation attached on the tip. This will shorten the tip lifespan.

■ Periodic maintenance

●

Tip

Wear and tear on the tip will vary due to the operating temperature as well as the quality and amount of
solder/flux used. Maintenance should be performed based on what suits your usage.

(1)

Turn the power ON.

(2)

Set the temperature to 250ºC (482ºF).

(3)

Once the temperature is stable, use the cleaning sponge to wipe the tip.

(4)

If there is any black oxidation on the solder plating, apply new solder containing flux and then wipe it off
with the cleaning sponge. Repeat this process until the oxidation is removed. Afterward, coat it with new

solder.

(5)

Turn the power off and remove the tip once it has cooled.
If you find flux, debris, and other particulates on anything other than the end of the tip, wipe it off with

industrial alcohol.

●

Handpiece
Remove flux, debris, and other particulates adhering to
the nipple.

It may cause contact failure inside the handpiece.

●

Iron holder

・ Press down the release button and remove the iron holder base, then clean the collected solder waste

from the iron holder.

・Rotate the cleaning wire as need to a clean side where solder is not accumulated.

Using the product at a temperature that is higher than necessary can accelerate tip deterioration
and damage parts that are susceptible to heat. Use the lowest temperature whenever possible.

Perform a visual check of the tip. Replace it if it is bent or considerably worn. Use the cleaning
sponge to wipe off any oxidation or old solder from the tip. Impurities on a circuit board can result

in poor soldering.

Use sleep mode instead of leaving the handpiece set to a high temperature for a long period of

time. This prevents tip oxidation which helps to maintain workability, which can extend the tip

lifetime. Turn off the power switch when not using the product for a long period of time.

(See " ■ Pausing work (sleep mode)" in "4-3. Operation")

Thoroughly clean the tip with the cleaning sponge and then coat it with new solder. Doing so can

prevent oxidation of the tip.

Is there any oxidation on the tip?

Is the offset value entered correct?

Is parameter No.

[OFF]? Change it to [On] to enable feature.

Plug unit into outlet.

Replace the fuse.
If the fuse is blown again, send the main unit
(including handpiece, power cord) back for

service.

Connect the compatible handpiece.

Turn off the power switch, reconnect the

handpiece, and turn the power switch back on
again.

Use a tip with a larger heat capacity.

Increase the set value.
( See the separate document "Parameter No.

in "Quick Parameter Settings")

Turn off the power switch, insert an applicable

genuine tip, and turn on the power switch again.

If the problem persists, replace the tip.

Insert tip firmly into the handpiece.
(Do not use excessive force)

Measure the resistance between the heating

element and sensor, and if the measured value is

abnormal, replace the tip. The normal resistance

values are as follows:

T39: 5.7 Ω ± 10％ (at room temperature)
　T50: 8.0 Ω ± 10％ (at room temperature)

T50T39

Measure the resistance between these points.Measure the resistance between these points.

Move the soldering iron away from the noise
source, or use other circuit for the power.

Set an appropriate temperature.

Remove the oxidation. (See "6. Maintenance")

Measure and adjust the value.

"4-3. Operation")
