High output setting
Enable or disable the high output function.
This function operates when the password setting mode is set to (partially enabled) or
(enabled).
When the high output function is enabled, it is possible to set higher values than usual in “ Output
upper limit setting”.
When the high output function is enabled, the maximum settable upper limit value and the maximum
parameter “ Output upper limit setting” will be 120. (When the function is disabled, the maximum
value for both is 100.)
Output upper limit setting
An upper limit for the blade output value can be set, making it impossible to set the value to higher than
the upper limit.
This function operates when the password setting mode is set to (partially enabled) or
(enabled).
If the set parameter value is , the maximum settable output value will be 80. It is possible to set
the values in increments of 5%.
(The initially set value is 100%.)
Auto sleep enable/disable setting
Enable or disable the auto sleep function.
The auto
sleep function saves the set output by approx. 50%, reducing the blade temperature and power
consumption.
This function extends the service life of blades.
When the auto sleep function is enabled, the auto sleep function will operate when the specified time has
elapsed after placing the handle on the handle holder.
The time until the auto sleep function operates can be set in“ Auto sleep time setting”.
: High output function is disabled.
: High output function is enabled.
: Auto-sleep is disabled.
: Auto-sleep is enabled.
In order to achieve high values 105 or more for the settable value, parameter “ High output
setting” should be changed to , then parameter “ Output upper limit setting” must
also be changed before changing the settable value.
When setting the output setting to 85 or more, regardless of the ON/OFF setting of the auto sleep
function, placing the handle on the handle holder will activate the auto sleep function.

until the auto sleep function operates after placing the handle on the handle holder. When the time is set
to , the auto sleep function starts immediately after placing the handle on the handle holder.
The auto sleep function does not work when the handle is not placed on the handle holder. When
the auto sleep function is operating, the unit will become active again when the handle is lifted off
of the handle holder.
NOTE
CAUTION
Do not leave the unit in the auto shutoff mode for a long time. If the unit will not be used for a long
time, be sure to switch off the power.
―NOTE ―
The auto shutoff function does not work when the handle is not placed on the handle holder.
If the auto shutoff function operates, switch the power off once and then switch it back on to start
using the unit again.

7. MAINTENANCE
Although blades are designed to resist oxidation, if oxidation of
the blades occurs and prevents you to do wire-stripping work
smoothly, use a wire brush lightly on the blade to remove the oxide.
Applying a wire brush strongly may damage the blades, resulting in
reduced service life. Therefore, do not brush blades excessively.
Leaving the unit in a no-load condition for a long time with the blade
heated highly may cause the surface to be oxidized, resulting in
reduced service life of blades due to overload applied to the heating
element.
Be sure to enable auto sleep and place the handle on the handle holder
when not using it.
Be sure to switch off the power switch if the unit will not be used for a
long time.

2. Suspension during use
1. Blown heating element
2. How to check whether the
connection cord is
connected or disconnected
3. How to replace the fuse
Check that no electrical abnormality occurs in the heating element.
Measure the resistance at normal temperature (15 to 25℃/59 to 77℉).
The normal value is 3.5 Ω ±10%If the measured resistance value is
abnormal, replace the blade with a new one.
Measure the resistance of this section of the heating element.
Attach normal blades (whose resistance value of heating elements is
normal) to both handles and measure the resistance value between
the connector pins.
Resistance between Pin 1 and Pin 5: 6.2 Ω to 8.0 Ω
If the resistance value is outside the above value range, replace
the HAKKO FT-8004 with a new one.
1. Unplug the power cord from the inlet.
2. Pull out the fuse holder.
3. Replace the current fuse with a new one.
4. Reassemble the fuse holder to its original condition.

WARNING
Unless otherwise specied, be sure to switch off the power and unplug the power plug when
performing the following procedures.
The unit should be maintained periodically to be able to use it in proper condition for a long
time. Since the degree of consumption of the unit varies depending on the use temperature,
etc., perform maintenance of the unit according to use conditions.
WARNING
Since the unit can reach a very high temperature, please work carefully. Except for special
cases, always turn the power switch OFF and disconnect the power plug before performing any
maintenance procedure.
