PRODUCT DESCRIPTION REPLACEMENT TIPS*
The Aoyue INT2702 Lead­Free Repairing System is a reworking equipment that combines the functionality of Hot Air Gun, Soldering Iron, Smoke Absorber, and Desoldering Gun 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 reaching 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 greater 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. PRODUCT ILLUSTRATION (*) Sold Separately

SAFETY PRECAUTIONS CAUTION: Improper usage can cause serious injury to personnel and/or damage to equipment and work area. For your own safety, please observe the following 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 from the main ● power source when moving the device from one location to another. Do not strike or subject the main unit (and all its components) to ● physical shock. Use carefully to avoid injury and damage to any part. Handle with care. CARE and MAINTENANCE Checking the soldering iron connection cord for damages 1. Remove the soldering tip and the nipple. 2. Push the socket out from the handle assembly. 3. Measure the resistance values between the connector and the lead wires at the socket as follows: Pin 1 ­ Red ( + ) Pin 3 ­ Blue (ground) Pin 5 ­ Black ( ­ ) If any value exceeds 0Ω (shorted) or ∞ (infinitely large — open), replace the handle assembly.
­ 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. 8 Replacing the heating element of the Hot Air Gun The heating element is found in the middle part of the hot air gun. The normal life of a heating element is 1 year under normal operating conditions. Steps: 1. Loosen the 3 screws that secure the handle. 2. Slide off the plastic tube. 3. Disconnect the ground wire sleeve. 4. Inside the pipe, the quartz glass and heat insulation are installed. Loosen the cable and take out the heating element. 5. Insert new heating element and reconnect the terminal. Be careful not to rub Heating Element wire. 6. Reconnect the ground wire after replacing the element. 7. Assemble the handle again. 21 CARE and MAINTENANCE ASSEMBLY and PREPARATION Blower/Vacuum Air Terminal Filters Filters should be cleaned and replaced regularly to avoid dirt which can clog the air passage. More importantly, this will also effectively clean the toxic fumes produced during soldering process. A. Aoyue Int2702 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. Soldering Iron Tip Always keep the solder­plated section of the tip/nozzle coated with a small amount of solder. Oxide coating on the tip of the nozzle reduces its heat conductivity. Coating the tip with a small amount of fresh solder ensures maximum heat conductivity is obtained. Replacing the Soldering Iron tip 1. Always turn OFF main power switch when removing or inserting a tip. 2. If the tip is hot, use the heat resistant pad to pull it out. 3. Insert the new tip fully into the handle. If the tip is not fully inserted (or if the tip is damaged), the device will produce five high beep sounds then show the following from the SOLDER/DESOLDER TEMPERATURE display panel (“13”). WARNING: Failure to remove the screw before using the equipment can cause damage to the system.
B. Soldering Iron 1. Install the solder wire to the soldering iron holder as in Figure 1. Figure 1. Soldering iron stand with solder wire holder 2. Connect the soldering iron cord assembly to the 6­pin output terminal found at the lower middle portion of the main unit. 3. Place the soldering iron to the soldering iron stand as shown above. C. Smoke Absorber 1. Attach the smoke absorbing tube to the suction vacuum cap. Make sure the cord connections are free from tangles. D.

Because of the difference in the heating element and size of the soldering iron tip and desoldering gun, the soldering iron will heat up faster than the desoldering gun. This is normal and does not have any impact on the system’s performance. 2. There will be a slight drop in temperature display once the trigger of the desoldering gun is used. This is due to rapid intake of air in which temperature is significantly cooler than the desoldering gun tip. When the system detects this, it will automatically adjust the temperature to compensate for the temperature difference. 15 — Reset Button 16 — Smoke Absorber Switch 17 — Soldering Iron / Desoldering Gun Activation Switch 10 19 OPERATING GUIDELINES F. Activating Soldering Iron & Desoldering Gun Auto­Sleep Mode Aside from the auto stand­by mode feature of the hot air gun, the device has a separate mechanism to put the soldering iron or desoldering gun into SLEEP mode after a certain period. By default, this is deactivated and the user must do any of the following two sets of procedures (whichever is applicable) in order to activate this feature. CONDITION 1: Device is initially switched OFF (main power switch OFF) 1. Make sure all function switches are deactivated. 2. Turn ON the main power switch. 3. Hold both UP and DOWN buttons of the SOLDER/DESOLDER TEMPERATURE Adjustment buttons. 4. Activate the SOLDER IRON switch while still holding both the UP and DOWN buttons from the previous step. 5. Make sure the following was momentarily shown from the soldering iron / desoldering gun temperature display panel (“13” from the control panel). 6. Release the two buttons to put the device into operation. CONDITION 2: Device is already switched ON 1. Hold both UP and DOWN buttons of the SOLDER/DESOLDER TEMPERATURE Adjustment buttons. 2. Press the RESET button once while still holding the two buttons from the previous step. 3. Make sure the same display above was momentarily shown from the soldering iron / desoldering gun temperature display panel. 4. Release the two buttons to put the device back into operation. NOTE: The auto sleep feature is automatically deactivated when OPERATING GUIDELINES
IMPORTANT REMINDERS: 1. Make sure the equipment is placed on a flat stable surface and all the heat­generating components 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. How to use the RESET button? The RESET button (“15” from the control panel) is used to reconfigure temperature and airflow level settings. In very rare cases, this may also solve some minor display or operation issues (see BASIC TROUBLESHOOTING GUIDE for further details). When pressed, the system will temporarily switch to stand­by mode then start the device using factory default operating parameters (provided the respective function switch is activated): Hot Air Gun Temperature: 100 o C Hot Air Gun Airflow Level: 51 Soldering Iron Temperature: 350 o C NOTE: Pressing the RESET button removes user­configured system values. Reconfiguration may then be necessary. How to use the CAL (calibration) utility? In special cases, it may be necessary to synchronize the amount of heat delivered by the soldering iron with an external temperature sensing device. This can be achieved by slowly tuning the CAL or calibration utility (“5” from the control panel) using a small screw driver until the approximate operating temperature on both devices are synchronized. the device is switched OFF or when the RESET button is pressed without doing the procedures specified above. 18 11 OPERATING GUIDELINES 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 by activating the main power switch (“9” from the control panel). E. Auto­Stand­By Mode (Hot Air Gun) The device has a built­in timer such that if the Hot Air Gun sits on its handle and remain idle for a certain period, the device will switch indefinitely to stand­by mode (provided the power delivered to the system remain uninterrupted). Once the countdown time has elapsed, the system will blow air (at room temperature) at a maximum rate in order to bring down the temperature. During this time, the prefix of the display for Hot Air Gun air temperature will change from “A” to “d”. Once the temperature drops to approximately 90°C, the Hot Air Gun will automatically stop and show an all­ dash display indicating that the system is now on stand­by. IMPORTANT: Initial control panel setting includes the BLOWER/ VACUUM ACTIVATION switch (“10” from control panel) set to “Blow Air”. 3. The display panels, 11 and 12 will temporarily show the product name in a scrolling manner and then display “OFF” on both rows once the scroll is finished (see below illustration). The system will remain at this state until the user activates a function. The device will automatically switch back into operation with the last user­defined parameters, i.e., hot air gun temperature, airflow level, etc., when the Hot Air Gun is lifted again from the handle. By default, the system has a 5­minute countdown time. This can be altered by the following procedures. 1. Upon system start­up, while the product name is scrolling from the B. HOT AIR GUN 1. Follow the initial procedures above, “A. INITIAL PROCEDURES”. 2. Activate “Hot Air Gun” switch (“14” from the control panel). 3. The system will immediately start to blow air at an airflow rate of 51 while rapidly and safely increasing the air temperature to 100°C (default system operating parameters). These values will be reflected from the Hot Air Gun Air Temperature and Air Pressure display panels, “11” and “12” from the control panel, respectively. The metal ball inside the air 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. (See illustrations on the next page.) 12 display panel, hold the UP button of the AIR PRESSURE Adjustment buttons and wait until “L05” is displayed. 2. Adjust the time using the UP and DOWN buttons of the HOT AIR GUN TEMPERATURE Adjustment buttons. 3. Confirm the change by pressing the DOWN button of the AIR PRESSURE Adjustment buttons. 4. The system will automatically switch back into operation and use the defined countdown parameter.
ADDITIONAL NOTES: 1. The alternative to first step above is to press the RESET button then hold the UP button of the AIR PRESSURE Adjustment buttons until “L05” is displayed. Note that pressing RESET removes user­defined configurations. 2. The countdown timer is configurable between 1 and 20 minutes. 17 OPERATING GUIDELINES D. DESOLDERING GUN 1. Connect the Desoldering Gun connection assembly to the 6­pin receptacle at the front of the control panel (“8” from CONTROL PANEL GUIDE). 2. Follow the initial procedures (“A. INITIAL PROCEDURES”). 3. Connect the vacuum tube to the Smoke Absorber Terminal or Vacuum Cap (“7” from the control panel). 4. IMPORTANT: Set the BLOWER or VACUUM ACTIVATION switch to “Vacuum Air”. 5. Activate the “SOLDER IRON” Activation switch (“17” from control panel). This will automatically start to increase the temperature of the NOTE: The system will produce a high beep sound when the default temperature (or when the desired temperature) is reached. 6. Adjust the desoldering gun temperature using the SOLDER/DESOLDER TEMPERATURE ADJUSTMENT buttons (“4” from the control panel). 7. You may start using the desoldering gun when the desired temperature is reached. Use the trigger of the desoldering gun to pick up unnecessary solder leads. 8. When desoldering task is finished, deactivate the SOLDER IRON switch. 9. Set the BLOWER/VACUUM ACTIVATION switch back to “Blow Air”. 10. Detach the desoldering gun connection assembly from the 6­pin receptacle at the control panel as well as the vacuum tube from the vacuum cap (if necessary). 11. Allow sufficient time for the desoldering gun to cool down before keeping in a safe storage. (Optional but recommended) NOTE: The soldering iron and desoldering gun operating temperature is configurable between 200°C and 480°C. IMPORTANT: Make sure the SMOKE ABSORBER switch is deactivated while using the desoldering gun. Otherwise, the desoldering gun will keep on sucking air indefinitely. 16 OPERATING GUIDELINES Default System Parameters (Hot Air Gun) 4. Adjust the air flow level using the AIR PRESSURE ADJUSTMENT BUTTONS (“3” from the control panel). The prefix of the display for Air Pressure will change from “F” to “E” while air flow level is being adjusted. It will return to “F” as soon as the desired level is reached. In the case below, the final airflow level is “F89”. 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 “A” to “b” indicating that air temperature is being adjusted. It will return to “A” while the temperature is gradually increasing or decreasing until the desired temperature is reached. In the example below, final air gun temperature is “A380”.
IMPORTANT: When adjusting the air 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 possibility of subjecting adjacent components to thermal shock. 13 OPERATING GUIDELINES OPERATING GUIDELINES 6. Reworking task can be started as soon as the desired hot air temperature and airflow level are reached, as also indicated from display panels “11” 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. Deactivate the Hot Air Gun Activation button first in order to activate the auto­cooling 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 “A” to “E” 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. See illustration below. C. SOLDERING IRON 1. Connect the Soldering Iron connection assembly to the 6­pin receptacle located at the front of the control panel (“8” from the CONTROL PANEL GUIDE). 2. Follow the initial procedures (“A.
