3. SAFETY INSTRUCTIONS

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:

CAUTION : Failure to comply with a CAUTION may result in injury to the operator, or damage to the

items involved. Two examples are given below.

WARNING: Failure to comply with a WARNING may result in serious injury or death.

CAUTION

The molten solder in the solder pot is dangerous since it reaches about 450°C/842°F. The pot cover also
becomes a high temperature when the power is ON. Wrong handling may cause burns or fire. Be sure to
observe the following precautions.

Use this product on highly stable metal workbench. Never use it near paper or other flammable materials.
Inform others in the area that the product is hot and should not be touched.
Never put water in the solder pot as this will cause solder to spatter out of the solder pot.
Tu rn the power off when not in use, or left unattended.
Before changing parts or storing the unit, be sure to turn the power off and allow the unit to cool to room
temperature.

Observe the following precautions to prevent accidents or damage to the unit.

Do not use the HAKKO FX-300 for applications other than soldering.
Do not modify the HAKKO FX-300.
Use only genuine HAKKO replacement parts.
Do not allow the HAKKO FX-300 to become wet, or use it with wet hands.
Be sure the work area is well ventilated. Soldering produces smoke.
Do not do anything else that might be dangerous.

WARNING

WARNING

When the power is ON, the temperature of the melted solder in the solder pot is approximately
450°C/842°F. Before changing the solder pot, be sure to unplug the power cord and let the solder
and the unit cool to room temperature.

The set temperature can be changed with the temperature regulator knob.
Tu r ning the knob clockwise increases the set temperature and turning the knob
counterclockwise decreases the set temperature.

1. Turn the power switch ON.

2. The temperature control is started, causing the temperature to increase.

NOTE:

Temperature depends on a soldering pot. Please use the table above as a guide.
Measure an exact temperature by the FG-100 or the FG-101 with an applicable temperature probe if
necessary.

8. PARTS LIST6. MAINTENANCE

WARNING

Unless otherwise directed, carry out these procedures after turning the power switch OFF,
unplugging the power plug and waiting for both the unit and the solder to sufficiently cool down.

● Changing the solder pot

WARNING

When the power is ON, the temperature of the
melted solder in the solder pot is approximately
450°C/842°F. Before changing the solder pot, be
sure to unplug the power cord and let the solder
and the unit cool to room temperature.

● Replacing the heating element

● Daily Check

Solder gradually corrodes and makes holes through
the stainless solder pot, which can lead to solder
leakage from the holes.

Daily check and replacement (if necessary) of the
solder pot is recommended to ensure comfortable
and safe execution of work.

CAUTION

Make sure that the solder pot has sufficiently
cooled down before performing the daily check.

1. Using the hexagon wrench (provided with the
HAKKO FX-300) to loosen the screws on both
sides of the unit.

NOTE:

Screws do not have to be removed.

2. Pull out the solder pot.

3. Insert a new solder pot and then tighten the
screws on both sides.

CAUTION

Check that the solder pot has been locked now.
Otherwise, the temperature may not increase
properly.

1. Loosen the screws on both sides of the unit.
(Fig. 1)

NOTE:

Screws do not have to be removed.

2. Pull out the solder pot. (Fig. 2)

3. Remove the setscrews (5 pieces) on the unit.
(Fig. 3)

4.

Slide the front panel frontward, disconnect the two

connectors (Fig. 4) from the connector circuit
board, and then pull out the units of the heating
elements (Fig. 5).

5. Insert the right and left heating elements in the
reverse procedure to removing the heating
elements.

CAUTION

The heating element is a discrete type.

How to check

1. Loosen two mounting screws on both sides of
the unit to pull out the solder pot. (Fig. 1)

2. Check for holes or leaks by visually inspecting
the surface of the solder pot. (Fig.2)

NOTE:

Visually inspect sides and bottom of the solder
pot. The life of the solder pot can be increased
if the pot is reinstalled with its orientation being
changed by 90 degrees.

3. Check the following areas for solder sticking.

l

Overflow tray

l

Around the heater of the unit, insides of the

heat insulator (Fig.3 and Fig.4)

7. TROUBLE SHOOTING GUIDE

WARNING

Before checking the inside of the FX-300 or replacing parts, be sure to disconnect the power plug.

● The unit does not operate when the
power switch is turned on.
