2. MAINTENANCE/CHECKING PROCEDURE
Performing proper and periodical maintenance extends the products life and contributes to use it always in
a good condition. Efficient soldering depends upon the temperature, the quality and quantity of the solder
and flux. Apply the following service procedure as dictated by the conditions of the usage.
WARNING
Since the soldering iron can reach a very high temperature, please work carefully. Except the
case especially indicated, always turn the power switch OFF and disconnect the power plug be-
fore performing any maintenance procedure.
l
Tip maintenance
1. Tip temperature
2. Cleaning
3. After use
4. When the unit is not being used
and the auto power shutoff is
not active.
5. Inspecting and cleaning the tip
CAUTION
NEVER file the tip to remove oxides!
High temperatures shorten tip life and may cause thermal shock
to components. Always use the lowest possible temperature when
soldering. The excellent thermal recovery characteristics of the
HAKKO FX-951 ensure effective soldering at low temperatures.
Always clean the soldering tip before use, to remove any residual
solder or flux adhering to it. Use a clean and moist cleaning
sponge No. A1536 (provided with the HAKKO FX-951) or the
HAKKO 599B tip cleaner. Contaminants on the tip have many
deleterious effects, including reduced heat conductivity, which
contribute to poor soldering performance.
Always clean the tip and coat it with fresh solder after use. This
guards against oxidation.
Never allow the unit to idle at a high temperature for extended
periods. This will allow the tip to become oxidized. Turn the pow-
er switch OFF. If it is to be out of service for several hours, it is
advisable to pull the power plug as well.
This procedure, if followed daily, will materially add to tip life.
1. Set the temperature to 250
°
C. (482
°
F.)
2. When the temperature stabilizes, clean the tip (see 2, above)
and check the condition of the tip. If the tip is badly worn or de-
formed, replace it.
3. If the solder plated part of the tip is covered with black oxide, apply
fresh solder, containing flux, and clean the tip again. Repeat until
all the oxide is removed, then coat the tip with fresh solder.
4. Turn the power OFF and remove the tip, using the heat resist-
ant pad. Set the tip aside to cool.
5. Remaining oxides, such as the yellow discoloration on the tip
shaft, can be removed with isopropyl alcohol.
l
Checking Procedure
WARNING
Unless otherwise directed, carry out these procedures with the power switch OFF and the power UNPLUGGED.
1. Check for a broken heater or sensor
Verify the electrical integrity of the heater and sensor.
Measure the resistance of the heater and sensor while at room
temperature (15 to 25
°
C.; 59 to 77
°
F.). It should be 8
Ω
±
10%. If
the resistance exceeds these limits, replace the tip.
1. Unplug the connection cord from the station.
2. Measure the resistance value between Pin 2 and the tip.
3. If the value exceeds 2
Ω
(at room temperature), perform the tip main-
tenance described on section 2, maintenance for the tip. If the value
still does not decrease, check the connection cord for breakage.
1. Remove the soldering tip and the sleeve assembly.
2. Turn the front piece of the HAKKO FM-2027 counterclockwise
and remove the cover.
3. Measure the resistance values between the connector and the
lead wires at the socket as follows:
Pin 1 – Red
Pin 2 – Green
Pin 3 – Black
Pin 5 – White
If any value exceeds 0
Ω
or is
∞
, replace the HAKKO FM-2028.
1. Unplug the power cord from the power receptacle.
2. Remove the fuse holder.
3. Replace the fuse.
4. Put the fuse holder back in place.
3. TROUBLE SHOOTING GUIDE
WARNING
Before checking the inside of the HAKKO FX-951 or replacing parts, be sure to disconnect the
power plug. Failure to do so may result in electric shock.
l
The unit does not operate when the
power switch is turned on.
l
The tip does not heat up.
• The sensor error is displayed.
l
Solder does not wet the tip.
l
The tip temperature is too high.
l
The tip temperature is too low.
l
The soldering iron error is
displayed.
l
The low-temperature alarm
tolerance error occurs
frequently.
l
Heater terminal short circuit error
is displayed.
l
Though the soldering iron is placed
on the iron holder, the sleep
function is not activated.
CHECK
: Is the power cord and/or the connection plug disconnected?
ACTION
: Connect it.
CHECK
: Is the fuse blown?
ACTION
: Investigate why the fuse blew and then replace the fuse. If
the cause can not be determined, replace the fuse. If the
fuse blows again, send the unit in for repair.
CHECK
: Is the tip inserted properly?
ACTION
: Insert the tip completely.
CHECK
: Is the connection cord and/or the heater/sensor broken?
ACTION
: See the appropriate section of this manual regarding how
to check the connection cord and/or the heater/sensor for
breakage.
CHECK
: Is the tip temperature too high?
ACTION
: Set the appropriate temperature.
CHECK
: Is the tip contaminated with oxide?
ACTION
: Remove the oxide (see “Tip maintenance” on section 2).
CHECK
: Is the connection cord broken?
ACTION
: See “Checking the connection cord for breakage” on
section 2.
CHECK
: Is the entered offset value correct?
ACTION
: Enter the correct value.
CHECK
: Is the tip contaminated with oxide?
ACTION
: Remove the oxide (see “Tip maintenance” on section 2).
CHECK
: Is the entered offset value correct?
ACTION
: Enter the correct value.
CHECK
: Is incorrect soldering iron connected?
ACTION
: Connect the HAKKO FM-2027 soldering iron.
CHECK
: Is the tip too small for the items to be soldered?
ACTION
: Use a tip with a larger thermal capacity.
CHECK
: Is the setting value for the low-temperature alarm tolerance too low?
ACTION
: Increase the setting value.
CHECK
: Is the tip for HAKKO FM-2027 soldering iron?
ACTION
: Turn the power switch OFF and insert the genuine HAKKO
FM-2027 tip. Turn the power switch ON.
CHECK
: Check that the connecting cable is inserted firmly into the jack.
ACTION
: Turn off the power switch and insert the connecting cable again.
