2. Safety Instructions
- Always ensure the machine is properly grounded before use.
- WARNING: HOT SURFACE. The heating element becomes extremely hot during operation. Avoid direct contact with the heating surface to prevent burns.
- Keep hands clear of moving parts, especially the mug clamping mechanism.
- Do not operate the machine with wet hands or in damp conditions.
- Unplug the machine from the power outlet when not in use or before cleaning and maintenance.
- Ensure adequate ventilation in the work area.
- Keep children and pets away from the machine during operation.
- Do not attempt to modify or repair the machine yourself. Contact qualified service personnel for assistance.

3. Product Overview and Features
The ST-110 Pneumatic Mug Press is designed for efficient and precise sublimation printing on mugs. It features intelligent full automatic control and a user-friendly interface.
Key Features:
- Pneumatic Full Automatic Control: Ensures consistent pressure and ease of use.
- Large LCD Panel: Displays temperature and time for easy monitoring and operation.
- User-Friendly Interface: Intuitive buttons for timing, mode selection, and temperature/time adjustment.
- Built-in Mini Vacuum Pump: Some models feature a built-in vacuum pump, eliminating the need for an external air compressor. (Note: Some configurations may require an external air compressor, refer to your specific model's setup.)
- Strong Current and Weak Current Separated Design: Enhances safety and extends product lifespan.
- Compact Design: Small footprint for convenient placement.

4. Setup
- Unpacking: Carefully remove the machine from its packaging and inspect for any damage.
- Placement: Place the machine on a stable, heat-resistant surface in a well-ventilated area.
- Power Connection: Connect the power cord to the machine's power input and then to a suitable electrical outlet (refer to specifications for voltage requirements). Ensure the power switch is in the OFF position before plugging in.
- Air Compressor Connection (if required): If your model does not have a built-in vacuum pump, connect an external air compressor to the inlet pipe on the machine. Ensure the air compressor is capable of providing the required pressure (0.05-0.65MPa).
- Initial Power On: Flip the power switch to the ON position. The LCD screen should light up.

5. Operating Instructions
5.1. Setting Temperature and Time
- Power On: Turn on the machine using the power switch.
- Set Temperature: Press the MODE button once to enter temperature setting mode. Use the PLUS (+) and MINUS (-) buttons to adjust the desired temperature (e.g., 180°C).
- Set Time: Press the MODE button again to enter time setting mode. Use the PLUS (+) and MINUS (-) buttons to adjust the desired time (e.g., 60 seconds).
- Exit Setting: Press the MODE button a third time to exit setting mode. The machine will begin heating to the set temperature.
5.2. Sublimation Process
- Prepare Mug: Wrap your sublimation transfer paper tightly around the mug, securing it with heat-resistant tape.
- Pre-heat: Allow the machine to reach the set temperature.
- Load Mug: Carefully place the prepared mug into the heating element.
- Start Press: Press the Stop/Start button. The pneumatic mechanism will automatically clamp the mug, and the timer will begin counting down.
- Monitor: The machine will maintain the set temperature and pressure throughout the cycle.
- Completion: Once the timer reaches zero, the machine will automatically release the mug. Carefully remove the hot mug using heat-resistant gloves.
- Cool Down: Allow the mug to cool completely before removing the transfer paper.
5.3. Adjusting Pressure (Pneumatic Rate)
The ST-110 features adjustable pressure for optimal transfer results. There are two adjustment valves, one for the rate at which the mug is clamped (in) and one for the release rate (out).
- Adjust In Rate: Turn the "ENTER" valve to adjust how quickly the mug is clamped.
- Adjust Out Rate: Turn the "OUT" valve to adjust how quickly the mug is released.
- Adjust these valves incrementally and test with a spare mug until the desired speed and pressure are achieved.

6. Maintenance
- Cleaning: Regularly wipe down the exterior of the machine with a soft, dry cloth. Ensure the machine is unplugged and cool before cleaning.
- Air Filter Maintenance: The air filter (if present) should be cleaned regularly to ensure proper pneumatic function.
- Take out the air filter from the machine.
- Pour out the collected water.
- Clean it regularly to improve equipment lifespan.
- Storage: Store the machine in a dry, dust-free environment when not in use.

7. Troubleshooting
Common Issue: Inflating pump is working, but air cylinder is not going forward.
Possible Cause: The solenoid valve may be stuck due to frequent pressing of the STOP button or lack of regular cleaning.
Solutions:
- Solution 1:
- Unscrew the solenoid valve.
- Take out the air cylinder (as shown in the diagram).
- Push the air cylinder forward and backward 10 times by hand.
- Reinstall the air cylinder and solenoid valve.
- Solution 2:
- Connect an air compressor.
- Unscrew the solenoid valve.
- Use the external air pressure to make the solenoid valve move forward and backward.
