the items involved.
NOTE : A NOTE indicates a procedure or point that is important to the process being
described.
EXAMPLE : An EXAMPLE is given to demonstrate a particular procedure point or process.
WARNING
To avoid damage to the unit, do not turn the power switch OFF until the pump stops automatically
by cooling down (until appears on the display) after use.
CAUTION
When the power is ON, the temperature of the hot air and the nozzle ranges from 100 to 450°C. (200
to 840°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 FR-803 or when leaving it unattended.
● Before replacing parts or storing the unit, allow the unit to cool and then turn the power OFF.
Observe the following precautions to prevent accidents or damage to the unit.
● 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.
● Make sure the work area is well ventilated.
● While using the HAKKO FR-803, donʼt do anything which may cause bodily harm or physical damage.

● 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 connector
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 normal value is 0Ω.
2. Measure the resistance value (b) of the
heater. The normal values are approx-
imately 33Ω (±10%) (100-120V), 85Ω (±
10%) (220-240V) at room temperature.
If the resistance value is abnormal,
replace the part.
(Refer to the instructions included with the
replacement part.)
● Replacing the Fuse

tacle.
