CAUTION

5. OPERATION

NOTE：

Make sure the power switch of HAKKO

FX-888D station is OFF.

1. Inserting the solder
Push and hold the trigger upward in the
direction of the arrow and insert the solder
into the solder inlet and pass solder through.
Solder will protrude from the guide nozzle.



The solder may become stuck inside the unit
if the trigger is pulled before solder protrudes
from the guide nozzle.

2. Feeding the solder



Put the trigger back into place after inserting
the solder.
Solder can be fed by pulling the trigger.

3. Adjusting the guide nozzle.
Adjust the position where the solder touches the tip.

Loosen the adjusting screw and move the

guide nozzle up or down.

4. Solder feed adjustment
Adjusting the solder feed pitch by turning the

solder feed adjusting screw with a screwdriver.

Quantity of solder feed will decrease by tightening.

5. Changing to a different solder diameter

When changing to the different solder diameter,

push and hold the trigger upward in the
direction of the arrow and pull out the solder
from the solder inlet.

Then, insert the new solder as shown in

“1. Inserting solder”.

5. OPERATION

B. Turn on the power switch

Turn on the power for HAKKO FX-888D soldering station.
The heater lamp flashes as the tip comes up to the set temperature.
The unit is now ready to perform soldering work.

●Place the HAKKO FX-8803 in the iron holder when not in use.
●Turn the power off when not using the station for a long time.

C. Calibration

Before using the HAKKO FX-8803, be sure to calibrate the station.

(Refer to the HAKKO FX-888D instruction manual.)

Use the HAKKO FG-100 Thermometer or HAKKO FG-101
Soldering Tester to measure thetip temperature.

D. Replacing the tip

1. Turn the nut counterclockwise, then remove

the tip enclosure and tip.

NOTE :

Do not loosen the nipple.

2. Insert the new tip and tip enclosure
into the HAKKO FX-8803.

Tighten the nut firmly, and fix the tip.

6. MAINTENANCE

Performing proper and periodic maintenance extends product life and contributes to the

quality of soldering work. 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 tip can reach a very high temperature, please work carefully.
Except where indicated, always turn the power switch OFF and disconnect the power plug
before performing any maintenance procedure.

Tip temperature

High temperatures shorten tip life and may cause thermal shock to components.

Always use the lowest possible temperature. The excellent thermal recovery characteristics
of the HAKKO FX-888D ensures effective soldering at low temperature.

Cleaning

Always clean the tip before use to remove any residual solder or flux adhering to it.

Use a cleaning sponge or the HAKKO 599B tip cleaner.

Contaminants on the tip may have negative effects, including reduced heat conductivity,

which contribute to poor performance.

When not in use

Never allow the unit to idle at a high temperature for extended periods. This will allow the
tip to become oxidized. Turn the power switch OFF. If it is to be out of service for
several hours, it is advisable to disconnect the power plug as well.

After use

Always clean the tip and coat it with fresh solder after use. This guards against oxidation.

Tip Maintenance

●

1. Set the temperature to 250℃.

2. When the temperature stabilizes, clean the tip and
check the condition of the tip. If the tip is badly worn or deformed, 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 resistant pad. Set the tip aside to

cool.

Do not file the tip in an attempt to remove the black oxide.

A. Connection

●Be sure to turn off the power before connecting

or disconnecting the cord assembly for
the iron to and from the receptacle to avoid
damaging the unit.

1. Connect the cord assembly of HAKKO FX-8803
to the receptacle of HAKKO FX-888D.

2. Place the soldering gun into the iron holder(option).

3. Plug the power cord into the power supply.

Push on the plug

until it stops,

making sure
it is securely
connected.

To disconnect, hold the plug.

receptacle

Instruction manual in the language of Japanese, English, Chinse, French, German and Korean

can be downloaded from the HAKKO Document Portal.

(Please note that some languages may not be available depending on the product.)

7. CHECK PROCEDURE

Disconnect the plug of the cord assembly
and measure the resistance value
between the pin of the connecting plug as follows.

●

If the values of “a” and ”b” are outside

the value in the table, replace the heating

element(sensor) and/or cord assembly.

●

If the value of “c” is over the value in the

table, remove the oxidization film by lightly

rubbing with sand-paper or steel wool
the points shown in the drawing on the right.

7. CHECK PROCEDURE

2. Broken cord assembly

There are two methods of testing the cord assembly as below.

1. Turn the power on and set the temperature control knob to 480℃. Then, bend the iron cord at
various locations along its length, including in the strain relief area.
If the LED heater lamp flashes, then the cord needs to be replaced.

The power lamp starts to flash when the temperature reaches 480℃ regardless of the

condition of the cord.

2. Check the resistance between the plug pin and the terminal lead.
Pin 1: Red Pin 2: Blue Pin 3 : Green
Pin 4 : White Pin 5 : Black

If it is higher than 0 Ω or ∞, the cord should be replaced.

8. TROUBLE SHOOTING GUIDE

●Solder gets stuck

Do you pull solder from a reel when using the trigger?
Do not pull solder from a heavy reel with the trigger.
Keep the solder loose (without tension) on the solder
inlet side at all times while soldering.
Is the solder inserted properly?
Refer to “1.Inserting the solder” under “5.OPERATION”.

1. Remove the adjusting screw and keep the support fitting apart from the housing.

2. Turn the nut counterclockwise and remove the tip enclosure and tip.

Be sure to remove the nut before removing the nipple. Removing the nipple first

could cause the heater leads to twist and cause a short circuit.

3. Turn the nipple counterclockwise and remove it from the gun.

4. Remove the 4 screws and open the housing.

5. Pull the grounding spring out of the sleeve.

*Measure when the heating element is at room temperature.

1. Heating element resistance (red) 2.5-3.5 Ω

2. Sensor resistance (blue) 43-58 Ω

If the resistance value is not normal, replace the heating element.

(Refer to the instructions included with the replacement part.)



After replacement

1. Measure the resistance between pins 4 and 1, 4 and 2, 5 and 1, and 5 and 2.
If it is not ∞, the heating element and sensor are touching. This will damage the circuit board.

2. Measure the resistance “a”, “b”, and “c” to confirm that the leads are not twisted and

that the grounding spring is properly connected.

When reassembling, be sure to match the convex part of the hexagon nut to concave
part of the housing.
