Ceramic Heating Element cannot stand excessive force. Never strike Soldering
Iron against work-bench or solid surface.
Make sure the Nut securing the Tip Enclosure is properly tightened.
Use exclusive Tips for 900 only.
Operate in lower tip temperature.
Exceptionally high thermal recovery allows a lower temperature
setting thereby protecting sensitive components and extending tip life.
Power off when replace the tip. Or Heating Element or Tip may be damaged.
Never file the specially plated tip.
Operating Instruction
•Set Up the Holder Part.
1
2
Attach the Holder Part to Station with Thumb Screw.
Holder Mounting Base is located on right
side of Station. Re-position to left side if
necessary refer to the drawing.
Angle of the Holder Part may be adjusted
by loosing Thumb Screw.
•Connection
Insert 5 - pin Connecting Plug into the Receptacle
on the Station,and lock it by turning
the outside ring of plug clockwise.
Warning : Connect or disconnect Cord Asse'y after power off. Or Control PWB
inside of the Station may be damaged.
Then, plug into properly grounded A.C. Outlet.
•Cleaning Sponge
Dampen Cleaning Sponge with water.
Special coted Tip may be damaged if cleaned in dry condition.
• Set the Temperature Control Knob to your desired temperature and turn
on the Power Switch. L.E.D. Heater Lamp comes on and off when Tip
temperature reaches to the figure you set. Now you can start the
soldering work.

_r These tips are tinnedfiatonly.
•Caution
1)Use exclusive tips for HAKKO 900 only.
2)The set temperature should be adjusted
according to the tip configuration.
If required, adjust the temperature with
"CAL" potentiometer on bottom of sta-
tion when changing tip configurations.
The temperature is increased by turning
"CAL" clockwise.
3) When using the Soldering Iron continu-
ously loosen Tip and remove oxide once
a week.
This helps prevent seizure and reduction
of Tip temperature.
4) Tin the tip daily as follows ;
1. Clean the Tip.
2. Set the temperature at 200°C (3920F).
3. Melt the solder gradually at the tip.
5 ) For heavy duty soldering, HAKKO re-
commends The 900L Iron with heavier
tips.
• The tip temperature may vary depending
on the figure. Refer to the left chart for the
quick and temporary adjustment.

Trouble Shooting Guide
Problem :Turn the power switch on, but Tip does not heat up or over heating.
Condition :The power lamp doesn't light up.
CheckPoint :Is the fuse blown?
Condition : The fuse is blown.
CheckPoints : 1. Is the inside of the iron short-circuited?
2. Is the grounding spring touching the Heating Element?
3. Is the Heating Element Lead twisted and short-circuited?
Condition : The power lamp lights up but the LED Heater Lamp doesntt blink.
CheckPoints : 1. Is the Connecting Plug connected correctly?
2. ls the Heating Element Lead broken?
Condition : The Power Lamp and The LED Heater Lamp lights up.
CheckPoints : 1. Is the Heating Element broken?
2. Is the Cord Asse'y broken?
Problem :The Tip heats up intermittently.
CheckPoint : 1. Is the Cord Asse'y almost broken?
Problem :The Tip doesn't wet.
CheckPoints : 1. Is the Tip temperature too high?
2. Is the Tip cleaned?
Problem :The Tip doesn't have desired temperature.
CheckPoint " Is the iron calibrated correctly?
Problem :The Tip can not be pulled off.
CheckPoints : 1. Is the Tip seisured?
2. Is the Tip expanded by deterioration.
NOTE: When repairs are needed, please send both the Soldering Iron and the station to your sales agent.

• How to check the breakage of Heating Element and Cord Asse'y.
Disconnect the Connecting Plug and measure the resistance
3value between pins of Connecting Plug as follows :
Between pin 4 & pin 5 2.5_-3.5 ohm
a(Heating Element) (Normal)
Between pin 1 & pin 2 43_58 ohm
b (Sensor) (Normal)
Between pin 3 & Tip Under 10 ohm
c (Grounding)
(I) If the value of "a" & "b" is different from above value, replace the Heating
Element (Sensor) or Cord Asse'y.
(2) If the value of "c" -- between pin 3 and tip (Grounding) is over above value,
remove the oxidizatipn film by rubbing lightly points shown as under with
sand-paper or steel wool.
Tip Enclosure Tip Nipple
• If the problem remains unsolved after check in the Soldering Iron,the Station may
have a problem.
Please contact your nearest HAKKO representative.
• If the tip doesn't wet.
• Tip temperature is higher than desired.
Recalibrate by adjusting "CAL" on the bottom of the Station.
• Tip is oxidized or dirty,
1 .Clean up with Cleaning Sponge.
2 .Set the Tip temperature at 250°C (482°F), and clean oxidized or dirty Tip with
steel wool.
• Never file or rub excessively specially plated tip.
i
3 .Melt the solder gradually at the tip.

Recalibrating of Iron Temperature
After replacing the Heating Element or replacing the tip, recalibrate the temperature
of the Soldering Iron.
1 ) Connect the Plug of Soldering Iron to the Station and lock it.
2 ) Set Temperature Control Dial at 400"C (752°F).
3 ) Turn the Power Switch on and wait till the L.E.D. Heater Lamp comes on and off.
4) Adjust the temperature of Tip at 400"C (752"F) by "CAL" on the bottom of the
Station using thermometer.
Conditions of Measurement
•Tip Temperature
The tip temperature was measured using HAKKO 191 thermometer.
• Insulation Resistance
The insulation resistance was measured between the tip and the lead of the Heating
Element using a 500V DC insulation resistance meter.
Caution : The insulation resistance cannot be measured between the tip and the
power plug as the transformer between the secondary part (Heating
Element) and the primary part acts as an insulator.

1) Turn the Nut Ocounterclockwise and remove the Tip Enclosure O, the Tip 0.
2 ) Turn the Nipple O counterclockwise and remove it from Iron.
3) Pull both the Heating Element _ and the Cord Asse'y _out of the Handle
(toward the tip of the Iron).
4 ) Pull the Grounding Spring _ out of the D-Sleeve.
5 ) Measure the resistance value at the Sensor and Heating Element of the Terminal.

• If the resistance value is not normal, replace the Heating Element.
• If the resistance value is normal, the Cord Asse'y may be broken.
6 ) Desolder the Heating Element Leads.
• In the above Item 5 &6, be careful not to damage the leads with soldering iron.

7) Solder the new Heating Element. Solder two Sensor Leads (blue) and Heating
Element Leads (red) on the Terminal Board _ as above drawing.
• There is no polarity between leads of the same color.
8 ) Insert the Grounding Spring into the Heating Element. And connect the Grounding
Spring and D-sleeve on the side of the Heating Element Leads.
9 ) Pull the Power Cord and fix the Heating Element in the Handle to prevent rolling.
10) Turn the Nipple and secure the Handle.
11) Replace the Nipple _, the Tip _, the Tip Enclosure O and secure the Nut O.
