The Aoyue INT738H Lead-Free Repairing System is a reworking
equipment that combines the functionality of Hot Air Gun, 70 watts
Soldering Iron and Smoke Absorber in one package.
It has several safety features such as the auto-cooling process of
the Hot Air Gun. This functionality protects the device (and its
components) from excessive heat upon reaching any of the following
conditions: (1) when the soldering gun remained idle on its resting
handle after a certain period and (2) when the temperature of the
device is above a safe threshold upon turning off. It has several
advanced features such as solder iron digital calibration, configurable
auto sleep for hot-air and soldering iron and switchable centigrade or
Fahrenheit readout.

SAFETY PRECAUTIONS
CAUTION: Improper usage can cause serious injury to personnel
and/or damage to equipment. For your own safety, please observe
the ff. precautions.
●Check each component after opening the package to make sure
everything is in good condition. If there are any suspected damage,
do not use the item and report the issue to your vendor.
●Turn OFF the Main Power Switch and unplug the device when
moving the device from one location to another.
●Do not strike or subject the main unit to physical shock. Use
carefully to avoid injury and damage to any part.
●Handle with care.
- Never drop or sharply jolt the unit.
- Contains delicate parts that may break if the unit is dropped.
●Make sure the equipment is always grounded. Always connect
power to a grounded receptacle.
●Temperature may reach as high as 480°C when switched ON.
- Do not use the device near flammable gases, paper and other
flammable materials.
- Do not touch heated parts, which can cause severe burns.
- Do not touch metallic parts near the tip.
●Disconnect the plug from the power source if the unit will not be
used for a long period.
- Turn OFF power during breaks, if possible.
●Use only genuine replacement parts.
- Turn OFF power and let the unit cool before replacing parts.
●The unit may produce a small amount of smoke and unusual odor
during initial usage. This is normal and should not yield any
negative result when reworking.
●Soldering process produces smoke — use on well ventilated place.
●Do not alter the unit, specifically the internal circuitry, in any
manner.

ASSEMBLY and PREPARATIONS
A. Main Station
As soon as the equipment has been removed from the package,
REMOVE THE SCREW located at the center of the bottom of the
main unit. This screw holds the pump in place during transportation.
B. Soldering Iron Stand
C. Soldering Iron
1. Connect the soldering iron cord assembly to the soldering iron
output terminal found at the lower middle portion of the main unit.
2. Place the soldering iron to the soldering iron stand.
D. Smoke Absorber
1. Attach the smoke absorbing tube to the suction vacuum cap. Make
sure the cord connections are free from tangles.
F. Hot Air Gun
The Hot Air Gun holder was installed on the station upside down for
packaging purpose. To set up the Hot Air Gun holder:
1. Loosen the two screws that secure the holder to the station.
2. Turn the holder right side up.
3. Re-fasten the two screws.
4. Place the hot air gun onto the holder in preparation for usage.
WARNING: Failure to remove the screw before using the
equipment can cause damage to the system.

IMPORTANT REMINDERS:
1. Make sure the equipment is placed on a flat stable surface
and all the heat-generating components are placed on their
respective holders or stands.
2. Ensure all function switches are OFF prior to reworking.
3. Ensure all terminal connections are properly secured.
IMPORTANT: Please refer to the CONTROL PANEL GUIDE
page for buttons and display panel directory.
OPERATING GUIDELINES
A. INITIAL PROCEDURES
1. Plug the device to the main power source using the power cord
provided in the package.
2. With all function switches deactivated and all terminal connections
properly secured, switch ON the device using the Main Power Switch
(“8” from the control panel).
3. The display panels, “10” and “12” will temporarily show the product
name in a scrolling manner and then display “OFF”on all rows once
the scroll is finished. The system will remain in this state until the user
activates a function.
B. HOT AIR GUN
1. Follow the initial procedures above, “A. INITIAL PROCEDURES”.
2. Activate Hot Air Gun Function Switch (“14” from the control panel).
3. The system will immediately start to blow air at an airflow rate of 50
while rapidly and safely increasing the air temperature to 100°C
(default system operating parameters). These values will be reflected
on the Hot Air Gun Air Temperature and Air Pressure display panels,
“13” and “12” from the control panel, respectively. The metal ball
inside the air pressure gauge (“1” from the control panel) will also
settle somewhere in the middle of the visible area indicating that the
system is blowing air at an average or normal rate.

OPERATING GUIDELINES
4. Adjust the air pressure level using the Air Pressure Adjustment Buttons
(“3” from the control panel).
5. Adjust the hot air gun air temperature using the Hot Air Gun
Temperature Adjustment Buttons (“2” from the control panel). The
prefix of the display for Hot Air Gun Temperature will change from
“H” to “” indicating that temperature is being adjusted. It will return
to “H” (indicating actual temperature) while the temperature is
gradually increasing or decreasing until the set temperature is
reached.
6. Reworking task can be started 1 minute after the desired hot air
temperature and airflow level are reached, indicated on display
panels “10” and “12”, respectively.
7. When reworking is complete, return the Hot Air Gun to its holder
and DO NOT immediately turn OFF the Main Power Switch .
8. Turn OFF the Hot Air Gun Function Switch first in order to activate
the auto-cooling process. The system will start to blow air (at room
temperature) at a fast rate to reduce heat from the hot air gun and
bring down the temperature to a reasonable safe level of 90°C.
During this time, the prefix of the display for hot air gun
temperature will also change from “H” to “C” while temperature is
gradually decreasing. Likewise, the air pressure level is at its highest
reading as indicated from the display panel. Once the temperature
drops to approximately 90°C the system will halt and display “OFF”
on the panel. It is now safe to switch OFF the Main Power Switch .
9. Turn OFF the Main Power Switch .
10. Unplug the device from the main power source.
IMPORTANT: When adjusting the hot air gun temperature, it is
strongly advised to initially increase the airflow level in order to
manage the system temperature. This is to protect the heating
element inside the handle from excessive heat and avoid the pos-
sibility of subjecting adjacent components to thermal shock.
