3. SAFETY INSTRUCTIONS
Warnings and cautions are placed at critical points in this manual to direct the operatorʼs at-
tention to significant items. They are defined as follows:
WARNING: Failure to comply with a WARNING may result in serious injury
or death.
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.
CAUTION
When the power is ON, the temperature of the hot air and the nozzle ranges from
100 to 450°C. (212 to 842°F.). To avoid injury to personnel or damage to items in the
work area, observe the following:
● Do not direct the hot air toward personnel or touch the metal parts near the nozzle.
● Do not use the product near combustible gases or flammable materials.
● Advise those in the work area that the unit can reach very high temperatures and should
be considered potentially dangerous.
● Turn the power OFF when no longer using the Hakko 852 or when leaving it unattended.
● Before replacing parts or storing the unit, allow the unit to cool and then turn the power
OFF.
To prevent accidents and failures, be sure to take the following precautions:
● Do not strike the handpiece against hard surface or otherwise subject it to physical
shock.
● Be sure the unit is grounded. Always connect power to a grounded receptacle.
● Do not disassemble the pump or the vacuum pump.
● Do not modify the unit.
● Use only genuine Hakko replacement parts.
● Do not wet the unit or use the unit with wet hands.
● Remove power cord by holding the plug – not the wires.
● Do not leave the vacuum pump on for long periods of time.
● After using, do not turn the power OFF until “P-S” is displayed on the temperature dis-
play.
● Make sure the work area is well ventilated.
● The Hakko 852 is not intended for use by young children or infirm persons without super-
vision.
● Young children should be supervised to ensure that they do not play with the Hakko 852.

A. Station Assembly
● Attach the handpiece holder.
Remove the handpiece holder mounting
screw from the side of the station. Attach
the handpiece holder to the station. (Fig-
ure 1)
(The handpiece holder can be installed
on either the left or right side.)
B. Handpiece Assembly
● Using vacuum function op-
erative nozzle (see page 17.)
1. Attach the nozzle.
a. Extend the vacuum pipe using the
vacuum pipe control knob. (Figure 2)
b. Remove the inside screw (M3 × 5)
of the nozzle. (Figure 3)
c. Loosen the nozzle mounting screw.
Pass the vacuum pipe through the
nozzle hole and attach the nozzle.
(Figure 4)
d. Tighten the nozzle mounting screw.
2. Attach the pad.
a. Attach the pad. (Figure 6)
b. Adjust the pad to an appropriate po-
sition.
Adjust the vacuum pipe so that the
pipe and pad protrude as little as
possible.
CAUTION
The nozzle and pads reach high temperatures,
get very hot. Be sure they are cool before at-
tempting to replace them.
CAUTION
● Pad
The pads do not last indefinitely. When they become deteri-
orated, replace them. Since exposure to high temperatures
causes them to deteriorate faster, Hakko recommends they
be cooled after use.
CAUTION
● Vacuum Pipe
Do not use excessive force.
When not using a nozzle, retract the vacuum pipe to the
shortest length. (Figure 5)

● Manual Mode (See page 8.)
In this mode, air-blow start and vacuum pump operation
are handled entirely by manual operation. Use this mode
when setting up Auto mode conditions, performing opera-
tions for which no conditions have been established, per-
forming maintenance, or executing a single operation.
● Remove Mode (AUTO) (See page 9.)
This mode is used when removing parts. After starting, the
heating time can be set by setting the timer. The vacuum
pump turns ON automatically.
● Install Mode (AUTO) (See page 10.)
This mode is used when installing parts. After starting, the
heating time can be set by setting the timer. The vacuum
pump turns OFF automatically.

(automatic)
④ Cooling start and air blow stop
(automatic)
●Installation
●Preparation
Apply an appropriate amount of solder
paste to P.W.B..
① Part Suction and Positioning
Press the VACUUM button on the hand-
piece (or the foot-switch). The part is
held to the pads by suction. Position
the part over the P.W.B.. (Figure 1)
② Start
Press the START button. Hot air blows
from the nozzle and soldering begins.
(Figure 2)
③ Vacuum Stop
After five seconds, the vacuum turns
OFF and the part is released from suc-
tion. (Figure 3)
④ Stop
When the timer reaches 0, cooling
begins. Make sure the solder has
hardened before lifting the handpiece.
(Figure 4)
CAUTION
While there are many advantages to using hot
air for soldering and desoldering, it is possible for
the process to result in defects such as bridges or
solder balls. Hakko recommends that all opera-
tors be made familiar with the equipment. Be sure
to inspect each completed product.

Temperature Display
1. Turn the power switch OFF .
2. Press and hold down the
UP
and
DOWN
buttons on
the temperature setting section simultaneously
and then turn the power switch ON.
3. Continue holding down both buttons until the
display shows
C
(for Celsius) or
F
(for
Fahrenheit). When the display shows
C
or
F
, the station is in parameter input mode.
● Pressing the
UP
and
DOWN
button will cause
C
or
F
to be displayed alternately.
● Press the button to select the scale. The pow-
er save time may now be entered.
② Power Save Time
The power save function automatically
turns off the hot air when it has blown
continuously for a specified amount of
time in manual mode. Power to the heat-
er is turned off and then the air is stopped
after the handpiece cools.
● When the station enters power save time setting
mode, either
30
or
60
is displayed. Either
30 minutes or 60 minutes can be selected.
● Pressing the
UP
and
DOWN
button will cause
30
or

● Press the button to enter your selection. The
sensor temperature may now be displayed.
③ Sensor Temperature Display
CAUTION
If the power is turned OFF before the param-
eter setting procedure is completed, the new
setting values will not be stored in memory.
● No data entry is required.
The value displayed is the temperature currently
detected by the sensor.
● To end parameter input mode, press the but-
ton. After displaying the temperature setting for
two seconds, the station returns to normal mode.

1. Unplug the power cord from the power recep-
tacle.
2. Remove the fuse holder.
3. Replace the fuse.
4. Put the fuse holder back in place.
●Broken Heater or Sensor
① Open the handpiece.
1. Retract the vacuum pipe to its shortest
length.
2. Remove the three screws holding the
handpiece together.
3. Move the tube downward.
4. Remove the pipe from the protruding
portion of the handle.
CAUTION
Quartz glass and heat insulation are inside the
pipe. Be careful not to drop or lose these items.
5. Disconnect the heater sensor connec-
tor and remove the heater.
CAUTION
Do not apply excessive force to the vacuum pipe.
② Measure the resistance value.
1. Measure the resistance value (a) of the
sensor. The correct value is 0Ω.
2. Measure the resistance value (b) of the
heater. The correct values are approx-
imately 33Ω (±10%) (100-120V), 85Ω
(±10%) (220-240V) at room tempera-
ture.
If the resistance value is incorrect, re-
place the part.

WARNING
● Before checking the inside of the Hakko 852 or replacing parts, be sure to disconnect the
power plug. Failure to do so may result in electric shock.
● The unit does not operate
when the power switch is
turned ON.
CHECK : Is the power cord 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 sensor broken?
ACTION : See the procedure for checking a po-
tentially broken sensor (p.15).
CHECK : Is the heater broken?
ACTION : See the procedure for checking a po-
tentially broken heater (p.15).
CHECK : Is the station in Auto mode?
ACTION : Put the station into Auto mode.
CHECK : Is the value outside the setting range?
ACTION :
Enter a value that is within the setting range.
CHECK : Is the vacuum button being pressed for
less than 0.3 second?
ACTION : Press the vacuum button for more than 0.3
second.
