Use the proper size cleaning
pin or cleaning drill for the
nozzle diameter.

The cleaning pin passes
completely through the

Insert the bit while turning it
clockwise.
Pull the drill bit out straight
without turning it.
Nozzle Maintenance
1. Inspect and clean the nozzle
Turn the power switch ON and let the nozzle
heat up.
●
Clean out the hole of the nozzle with the
nozzle cleaning pin.
●
If the cleaning pin does not pass through the
hole in the nozzle, clean with the cleaning
drill.
●
Check the condition of the solder plating on
the nozzle tip.
●
Check visually if the nozzle was eroded.
CAUTION
The handpiece may be extremely hot. During maintenance, please work carefully.
The cleaning pin will not pass through the
nozzle until the solder inside the nozzle is
completely melted.
CAUTION
CAUTION
•
If the cleaning drill is forced into the nozzle, the drill bit
could break or be damaged.
•
Please use the proper size cleaning pin or cleaning drill
for the nozzle diameter.
*
If the nozzle is still in a good condition, put some fresh solder on the nozzle tip to
protect solder plated area from oxidation.

15. MAINTENANCE (Desoldering Tool) (continued)
・
Erosion may not be able to be confirmed
visually, so replace it when it starts to
work inefficiently.
・
Special plating is applied to the inside and
surface of the nozzle hole, but if it is
exposed to high-temperature soldering for
a long time, it may be eroded and
temperature stability may not be maintained.
The caliber has
expanded due
to erosion.
Solder plating part
The solder plating is coming off.
The nozzle hole is eroded.
CAUTION
Remove the enclosure pipe
and the nozzle with the provided
wrench.

careful when removing them.）
2. Disassemble the heating element.
CAUTION
The heating element is
very hot during operation.
1. Turn the power switch OFF.
2. When the filter pipe is cool to the touch, push down
on the release knob at the back
of the handpiece and remove the filter pipe.
3. Examine the seals (front and filter holders) at each end of the filter pipe.
Replace : Stiff and/or cracked.
4. Examine the Pre-filter: Remove solder adhering to the waste collector.
5. Examine the ceramic paper filter.
Replace : Ceramic paper filter is showing signs of stains from flux, is stiff,
or contains any solder.

3. Clean out the tube in the heating
element with the provided cleaning
pin.
●
Turn the power off after cleaning.
Scrape away all oxidation from the tube in the heating
element until the cleaning pin passes cleanly through
the tube.
CAUTION
・
Be sure the solder in the tube in the heating element is completely heated, before
cleaning the tube.
・
If the cleaning pin does not pass through the tube in the heating element, replace
the heating element.
