P.W.B

Ensure the front cross bar is secure. Place one edge of
the P.W.B. against the holder clips. Bring the rear cross bar
into contact with the opposite edge of the P.W.B. so that
the holder clips secure the P.W.B..

4. INITIAL SETUP

C.

Attaching the thermocouple

insert the thermocouple in the thermocouple connector;
then, bring the tip of the thermocouple into contact with
any location where you want to take measurements or a
part you want to heat. (Figure 2)

CAUTION

S-E is indicated when the thermocouple is not
properly connected to the preheater body or has an
open circuit. If you receive an error, insert the
thermocouple properly in the thermocouple connector,
then, turn on the power switch again.

■ Connection with the HAKKO

FR-803B/FM-206 (Optional)

The HAKKO FR-803B and HAKKO FM-206 can be
connected to the HAKKO FR-872 with a connecting
cable, which permits the HAKKO FR-803B /
FM-206 to start/stop the HAKKO FR-872.

CAUTION

Connect the HAKKO FR-872 and FR-803B /
FM-206 by the connecting cable before turning
on the power switch.

1. HAKKO FR-803B

● START

When pressing the Hot Air button of the HAKKO
FR-803B handpiece, the HAKKO FR-872 will work
in conjunction with the HAKKO FR-803B. the
HAKKO FR-872 and FR-803B will be operated by
the setting and mode of each unit.

NOTE:

When pressing the START/STOP button of the
HAKKO FR-872, Only the HAKKO FR-872 will be
activated.

● STOP

Press the Hot Air button of the HAKKO FR-803B
handpiece or turn off the power when the profile is
finished in auto mode.

CAUTION

Be sure that both the HAKKO FR-872 and HAKKO
FR-803B are starting from the STOP state. If the
FR-872 is running and the FR-803B is not, starting
the FR-803B will effectively stop the FR-872.

Please refer to the HAKKO FR-803B instruction
manual for its use.

2. HAKKO FM-206

● START

When pressing the Hot Air button of the HAKKO
FM-2029 handpiece with the HAKKO FM-2029
connected to the HAKKO FM-206, or pressing the
START/ STOP button of the HAKKO FR-872, the
HAKKO FR-872 will work in conjunction with the
HAKKO FM-206. The HAKKO FR-872 and FM-206
will be operated by the profile of each unit.

● STOP

Press the Hot Air button of the HAKKO FM-2029
handpiece while the HAKKO FM-2029 is connected
to the HAKKO FM-206, or press the START/ STOP
button of the FR-872. If the HAKKO FM-206 is in
AUTO mode, the FR-872 will stop automatically
when the FM-206 reaches the end of the
programmed profile.

CAUTION

When using the HAKKO FR-872 in Auto Mode, it is
necessary to ensure that each stage of the profile
has the same time setting as the profile on the FR-803B
or FM-206. It is also necessary to set the FR-803B or
FM-206 to use CLOSED timing.

5. OPERATION

A. Selecting the desired mode

Use the MODE button to select the desired mode. (Normal or Auto mode)
Each mode (Normal or Auto) is divided into the following control modes:
Power mode: The preheater is controlled by setting the output.
T/C mode : The preheater is controlled by setting the temperature.

CAUTION

If the preheater is used in combination with a hot air rework station, be sure the heater is not exposed directly to the hot air.

Normal modes

● Power mode

The unit is controlled according to the setting output during operation.

LED lamp :
POWER MODE

● T/C mode

The unit is controlled so that measurement temperature by the thermocouple becomes the setting
temperature during operation.

LED lamp :
T/C MODE

Auto modes

In auto modes, the preheater automatically returns to its previous state when all associated operations are
completed. The unit will return to standby even when pressing the START/STOP button during operation.

● Auto power mode

The output (%) and time (sec) are controlled
according to the profile set in 3 steps.
It’s possible to store ten profiles.

7. MAINTENANCE

In order for you to use the preheater in optimum condition for a long time, it is important that you perform maintenance work
on a regular basis. The degree of wear and tear the preheater may incur varies depending on the temperatures it is used at
and the environment it is used in. Provide appropriate care according to the conditions of its use.

WARNING

When replacing the heater:

・Make sure the heater and lamp cover have sufficiently cooled.
・Be careful for any injures which may be caused by sharp edges on the lamp cover.

■ Burned-out heater

Measure the resistance value between
the terminals.

■ Replacing the heater

②

CAUTION

･ Mount the heater so that the sealing at the center faces downward (on the reflector side).
･ Be sure that the grounding wire of the lamp cover is properly connected.

Measure the resistance of the heater. If the heater has an

open circuit, replace the heater.

1. Remove the screws from the both sides of the unit and

detach the cover.

①

2. Lift and move the lamp cover out of the way of the lamps.

CAUTION

Do not remove the nuts securing the grounding strap to the
lamp cover.

3. Replace the heater.

CAUTION

･ Do not subject the heater to excessive impact.
･ Do not hold the heater by its glass portion at the center with

bare hands.

･ For replacement, hold the end of the heater, and detach it

from the socket at an angle.

Replace the lamp cover and re-install the cover of the unit.
