CAUTION
This product includes such features as electrically conductive plastic parts and grounding of the handpiece and station as
measures to protect the device to be soldered from the effects of static electricity. Be sure to observe the following instructions:
1. The handle and other plastic parts are not insulators, they are conductors. When replacing parts or repairing,
take sufficient care not to expose live electrical parts or damage insulation materials.
2. Be sure to ground the unit during use.

3. WARNINGS, CAUTIONS AND NOTES
Warnings, cautions and notes are placed at critical points in this manual to direct the
operator’s attention to significant items. They are defined as follows:
To prevent accidents or damage to the HAKKO FX-801, be sure to observe the following:
●Do not use the HAKKO FX-801 for applications other than soldering.
●Do not strike the iron against hard objects to remove excess solder.
This will damage the iron.
●Do not modify the HAKKO FX-801.
●Use only genuine Hakko replacement parts.
●Do not allow the HAKKO FX-801 to become wet, or use it with wet hands.
●Remove power and iron cords by holding onto the plug.
●Be sure the work area is well ventilated. Soldering produces smoke.
●Be sure the cooling fan at the rear of the station is unrestricted.
●While using the HAKKO FX-801, don’t do anything which may cause bodily harm or
physical damage.
Failure to comply with a CAUTION may result in injury to the operator, or damage to the
items involved.
Failure to comply with a WARNING may result in serious injury or death.WARNING:
CAUTION :
WARNING
When power is ON, the tip will be hot.
To avoid injury or damage to personnel and items in the work area, observe the following:
●Do not touch the tip or the metal parts near the tip.
●Do not allow the tip to come close to, or touch, flammable materials.
●Inform others in the area that the unit is hot and should not be touched.
●Turn the power off when not in use, or left unattended.
●Turn the power off when changing parts or storing the HAKKO FX-801.
●This appliance can be used by children aged from 8 years and above and
persons with reduced physical, sensory or mental capabilities or lack of
experience and knowledge if they have been given supervision or instruction
concerning use of the appliance in safe way and understand the hazards
involved.
●Children shall not play with the appliance.

1. Assemble as shown:
●Insert the tip cleaner securely into the Iron holder base.
2. Operation:
First, remove any excess solder from the tip by thrusting the tip into the cleaning
wire. (Do not wipe the tip against the wire. This may cause molten solder to
spatter.) When the wire becomes dirty or loaded with solder, turn the wire until a
clean surface is presented. When changing the cleaning wire, lift the case top
vertically to prevent solder debris from falling out.

5. INITIAL SETUP
CAUTION
Do not set up the iron receptacle too high, the
temperature of the soldering iron will become very hot.
Connecting cable
CAUTION
Be sure to turn off the power before connecting or
disconnecting the connecting cable.
A. Iron holder
●Loosen the adjusting screws to change the angle
of the iron receptacle as you like, then tighten the
screws.
●Use of the sleep function.
When using the sleep function, insert one end of the connecting cable
into the jack at the back of the iron holder and the other end into the
jack at the back of the soldering station to connect them.
B. Handpiece cord assembly
Pass the iron cord through the hole in the heat
resistant pad.
C. Soldering station
1. Insert the power cord into the receptacle at the back of the station.
Insert the soldering iron cord into the receptacle at the front of the
station.
2. Set the iron in the iron holder.
3. Plug the power cord into a grounded wall socket.
The iron receptacle has two grooves. If the edge
of the iron tip is likely to come into contact with the
iron holder or the iron holder becomes hot, use the
alternate groove to attach the iron receptacle.
Normal conditions
If the iron holder
becomes hot
Insert the plug into
the receptacle until
it clicks.
To disconnect, pull the plug
from the receptacle while
pressing down the tab on
the plug.
CAUTION
Be sure the power switch is OFF before connecting or disconnecting the
soldering iron cord. Failure to do so may result in damage to the circuit board.
CAUTION
The HAKKO FX-801 is protected against electrostatic
discharge and must be grounded for full efficiency.

8. 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.
Since the soldering iron 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.
WARNING
●Tip maintenance
1. Tip temperature
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-801 ensures effective soldering at low temperatures.
2. Cleaning
Always clean the soldering iron tip before use, to remove any residual solder or flux adhering to it
by using a tip cleaner. Contaminants on the tip have many deleterious effects, including reduced
heat conductivity, which contribute to poor soldering performance.
3. After use
Always clean the tip and coat it with fresh solder after use.
This guards against oxidation.
4. When the unit is not being used
Never allow the unit to idle at a high temperature for extended periods. This will cause the tip to
become oxidized. Turn the power switch OFF. If it is to be out of service for several hours, it is
advised to disconnect the power plug as well.
5. Inspecting and cleaning the tip
If followed daily, this procedure will materially add to tip life.
a. Set the temperature to 250℃ (482℉).
b. When the temperature stabilizes, clean the tip and check the condition of the tip.
If the tip is badly worn or deformed, replace it.
c. 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.
d. Turn the power OFF and remove the tip, using the heat resistant pad. Set the tip aside to cool.
Remaining oxides can be removed with isopropyl alcohol.
CAUTION
NEVER file or use abrasive materials on the tip to remove oxides!

■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℃; 59℉ to 77℉)
It should be 3.4Ω±10％. If the resistance exceeds these limits, replace it.
■Check the grounding line
1. Unplug the iron cable from the station.
2. Measure the resistance between pin #2 and the soldering iron tip (with iron cable connected to
the HAKKO FX-8002).
3. If the value exceeds 2Ω (at room temperature), perform the tip maintenance in page 16.
If the value still does not decrease, check the connection cord for breakage.
■Check the iron cable for breakage
Measure the resistance of the connector pin.
Between Pin #1 to Pin #3 - 3.0 to 3.8Ω
If the resistance exceeds these limits, replace the iron cable.
Contact your HAKKO representative.
■Replace the fuse
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.
Unless otherwise directed, carry out these procedures with power switch OFF and the power UNPLUGGED.
