Product Description - aoyue INT 738 Instruction Manual

PRODUCT DESCRIPTION
The Aoyue I 738 Professional Repairing System is a reworking
NT
equipment that combines the functionality of a Hot Air Gun, Soldering
Iron, and Smoke absorber in one sophisticated package.
One of the notable features of this device is the auto­cooling process
of the Hot Air Gun. This functionality protects the device (and its
components) from excessive heat by blowing air (at room temperature)
upon achieving any of the following two 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.
This will be discussed in further detail together with the complete features
in the succeeding sections of this manual.
Finally, the unique, innovative design with digital control panel and
display provides precision, safety, and ease of use to match all reworking
requirements.

BASIC TROUBLESHOOTING GUIDE
PROBLEM 6: AIR PRESSURE LEVEL IS SIGNIFICANTLY LOW NO
MATTER HOW HIGH THE AIRFLOW LEVEL IS CALIBRATED
Case 1: Check the mains voltage (AC power source). If the voltage level
falls significantly low, about 15­20% lower than the standard, there will
also be a noticeable drop in the air pressure level.
SOLUTION: Please refer to your local power service provider.
Case 2: The microcontroller might have detected the operating
frequency incorrectly. The user will notice that airflow level is weaker
with reference to the airflow gauge compared with the displayed value.
SOLUTION: Try to press the RESET button on the panel to let the
device re­detect the proper operating frequency.
PROBLEM 7: SOLDERING IRON TEMPERATURE DISPLAY PANEL
SHOWS "PLUG" CHARACTERS
Case 1: The system shows "
display panel .
SOLUTION 1: Check if the soldering iron connection assembly is
properly connected and secured to the receptacle on the control panel.
SOLUTION 2: Make sure the soldering iron tip is properly inserted
and secured inside the handle. Lose contacts between the tip and handle
can also cause this error message.
PROBLEM 8: DISPLAY AND OTHER DEVICE OPERATION ISSUES
SOLUTION: Try to switch OFF the device and switch ON again. Unplug
the system from the main power source and plug in again when
necessary
OTHER PROBLEMS NOT MENTIONED:
