6. Maintenance

• Cleaning: Wipe the device with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
• Storage: Store the GT150 in a cool, dry place away from direct sunlight and extreme temperatures. Ensure the air hose is detached and stored properly to prevent damage.
• Battery Care: To prolong battery life, charge the device at least once every three months if not in regular use.
• Heat Dissipation: The device is designed with efficient heat dissipation. During prolonged use, it may become warm, which is normal. Allow it to cool down if it feels excessively hot.

7. Troubleshooting

• Device Not Turning On: Ensure the battery is charged. If not, connect it to a power source using the USB-C cable.
• Inflation is Slow or Ineffective: Check that the air hose is securely connected to both the inflator and the item's valve. Ensure the correct air nozzle is used and that the preset pressure is appropriate for the item.
• Device Stops Unexpectedly: The auto-shutoff feature may have activated if the preset pressure was reached. If not, the device might have overheated during prolonged use. Allow it to cool down before resuming operation.
• Inaccurate Pressure Reading: Ensure the air hose is fully and correctly attached to the valve stem. A loose connection can lead to inaccurate readings.
