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.

Preparation: Assembly and Electrical Connectio
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.
