2. Safety Precautions

• Always operate the device in a well-ventilated area.
• Ensure the power supply matches the specified voltage (110V).
• Do not touch the heating plate during operation or immediately after shutdown, as it remains hot.
• Wear appropriate personal protective equipment (PPE), such as heat-resistant gloves and safety glasses.
• Keep flammable materials away from the heating station.
• Disconnect power before cleaning or maintenance.
• The device features an anti-static design; however, proper grounding practices should still be followed when handling sensitive electronic components.

4. Setup

1. Unpacking: Carefully remove the preheating station from its packaging. Inspect for any damage during transit.
2. Placement: Place the unit on a stable, heat-resistant, and level surface in a well-ventilated area. Ensure adequate clearance around the unit for proper airflow.
3. Power Connection: Connect the provided power cord to the power input socket on the rear of the unit and then to a grounded 110V AC power outlet.
4. Initial Inspection: Verify that the power switch is in the "OFF" position before connecting to power.
5. Adjusting Grippers: The station includes adjustable grippers to secure PCBs. Loosen the knobs, position the grippers to hold your circuit board securely, and then tighten the knobs.

5. Operating Instructions

1. Power On: Flip the "ON/OFF" switch to the "ON" position. The digital display will illuminate, showing the current temperature.
2. Set Temperature: Rotate the "SET TEMPERATURE" knob to adjust the desired preheating temperature. The digital display will show the set temperature. The unit will begin heating to reach this target.
3. Monitor Temperature: The "ACTUAL TEMPERATURE" indicator will show the current temperature of the heating plate. Use the included thermometer to verify the PCB temperature if precise monitoring is required.
4. Place PCB: Once the desired temperature is reached, carefully place the PCB onto the heating area, securing it with the adjustable grippers if necessary.
5. Preheating Process: Allow the PCB to preheat to the required temperature. The infrared ceramic heating body ensures uniform heating across the 130x130mm area.
6. Power Off: After use, turn the "ON/OFF" switch to the "OFF" position. Allow the unit to cool down completely before handling or storing.
