●Temperature may reach a high of 480°C when turned on.
- Do not use near inflammable/flammable materials.
- Do not touch heated parts, can cause severe burns.
- Do not touch metallic parts near the Tip.
●Handle with Care
- Never drop or sharply jolt the unit.
- Contains delicate parts that may break if unit is dropped.
●Disconnect plug when not to be used for a long period of time.
- Turn off power during breaks.
●Use only genuine replacement parts.
- Turn-off power and let unit cool before replacing parts.
●Soldering process produces smoke, make sure work area is well venti-
lated.
●Do not modify unit
●Never touch the element or tip of the soldering iron. They are very hot
(about 400°C) and will give you a nasty burn.
●Take great care to avoid touching the mains flex with the tip of the
iron. The iron should have a heatproof flex for extra protection. An
ordinary plastic flex will melt immediately if touched by a hot iron and
there is a serious risk of burns and electric shock.
●Always return the soldering iron to its stand when not in use.
●Work in a well-ventilated area. The smoke formed as you melt solder
is mostly from the flux and is quite irritating. Avoid breathing it by
keeping your head on the side and not directly above of your work.
●Wash your hands after using solder. Solder may contain lead which is
a poisonous metal.
CAUTION: Misuse may cause injury and physical damage.
For your own safety, be sure to comply with the following precaution.

Tip Temperature
If the tip temperature is too high, it decreases the life of the tip. So
we suggest you to use the lowest *possible* tip temperature when sol-
dering. This not only prolong life of the tip, it also quickens heat recov-
ery and decreases harm to sensitive components.
Cleaning
The soldering iron tip should be cleaned after use by wiping it on
the damp sponge found in the soldering iron stand, this is to get rid of
burnt solder or fluxes that causes oxidation on the tip. If the tip has oxi-
dation, apply solder and wipe using the damp sponge, repeat these
steps until oxidation is removed.
Regular cleaning is also needed when tips are used for prolonged
period of time (remove tip from soldering iron and clean it once a
week). The solder tips are chrome electroplated on the surface and
should be bright silver with no flux residue or solder on it. If the tip
shows disfiguration or has rust on it. Change the tip.
When Not in Use
If a soldering iron does not have a thin consistent layer or solder
over the entire surface, the tip has not been properly tinned. When you
are not using your iron, make sure you leave a large lump of solder on
the tip. This maintains the tinning on the tip, and the tip will last much
longer. Many technicians mistakenly clean the tip before they put the
iron into the holder. Leave the solder on the tip to protect it.
SOLDER TIP CARE and MAINTENANCE
Remember to tin the tip after cleaning in preparation for the next use.

TESTING THE HEATING ELEMENT
To test if the heating element is in working condition:
Cool down assembly to room temperature before continuing the tests
below:
1. Follow “disassembling the hand piece” guide.
2. Do the following tests on the hand piece PCB board:
◆Resistance value of heating element 18 — 23 Ω
◆Resistance value of sensor 2.3 — 3.5 Ω
◆After testing check results with the following:
◆If the resistance value is not as stated above replace the heating
element.
◆If a 0 Ω or infinite resistances are measured check for shorts or
open circuits.
◆Itermittent readings can also be caused by cold solder double
check solder points if the heating element has recently been
replaced.

TROUBLESHOOTING CONNECTIONS
The 5 pin socket can be tested to detect faults in the hand piece:
Before plugging in the hand piece conduct the conti-
nuity test as shown:
If any of the combination registers a short re-
view the steps in “replacing the heating element” to
ensure proper connections.
Pins 4 & 2 ∞
Pins 4 & 1 ∞
Pins 5 & 1 ∞
Pins 5 & 2 ∞
Warning: Ensure none of the above mentioned conditionsare pre-
sent before plugging in the hand piece. Failure to do socan dam-
age the internal circuitry of the unit.
Follow the following direction to test for hand piece cord
faults:
Test 1: Rendering physical strain to the cord
1. Turn on the unit.
2. Set temperature to 480 °C.
3. Bend and straiten the entire length of the cord bit by bit. The
heater lamp should always be lit while doing so. If the heater
lamp becomes intermittent the cord is faulty and should be re-
placed.
Test 2: Resistance test
1. Follow the steps in disassembling the hand piece .
2. Test for continuity between the pins and colored wires at the hand
piece PCB, all matching contacts at the PCB and wires should reg-
ister 0 to 2 Ω.
Note: the Heater lamp will blink if the temperature of the soldering iron tip has
reached the set temperature i.e. 480°C. this is not an indication of a faulty cord.

REPLACING SOLDERING IRON CORD /FUSE
When cord is proven to be faulty follow the steps to replace the cord:
1. Follow the steps in disassembling the hand piece.
2. Make a brief illustration of wire configuration in the PCB.
3. Unsolder the wires connecting the hand piece PCB and cord to-
gether.
4. Unattached the grounding cord and grounding spring together.
5. Detach the PCB from the cord by releasing the metal grips located
at the bottom of the PCB .
6. Slide out the main handle , soft grip pad and tail end of the hand
piece.
7. Insert the tail end and soft grip pad into the new cord.
8. Insert the new cord thought the main handle.
9. Solder the wires back into the PCB.
10. Reattach grounding spring to the new cord.
11. Bend the metal on the end of the PCB to grip the cord firmly.
