Setup
- Charging the Device: Before first use, fully charge the compressor using either the provided 12V car charger or the 230V home charger. The battery protection device will prevent deep discharge. Note: Do not operate the pump while it is charging from the mains power supply.
- Attaching the Air Hose: Screw the air hose securely onto the compressor's air outlet. Ensure a tight connection to prevent air leakage.
- Connecting to Item: Select the appropriate adapter (if needed) and connect the air hose to the valve of the item you wish to inflate. For standard car/bicycle valves, the hose connects directly.

Operating Instructions
- Power On: Press the power button to turn on the compressor. The digital LCD display will illuminate, showing the current pressure.
- Select Pressure Unit: Press the 'M' button (Mode) to cycle through the available pressure units: PSI, BAR, and KG/CM².
- Set Target Pressure: Use the '+' and '-' buttons to adjust the desired target pressure. The display will show the preset value.
- Start Inflation: Press the power button again to begin inflation. The compressor will automatically stop once the preset pressure is reached.
- LED Flashlight: Press the dedicated LED light button to turn the ultra-bright LED flashlight on or off. This is useful for nighttime operation.
- Safety Warning: The air hose may become hot during operation. Exercise caution when handling. To prevent overheating and damage, do not operate the compressor continuously for more than 10 minutes. Allow at least 10 minutes of rest after each 10-minute operation cycle.

The Oasser P1S is suitable for various inflation tasks, including tires and sports equipment.
Maintenance
- Cleaning: Wipe the compressor with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners. Keep the air inlet and outlet free from dust and debris.
- Battery Care: To prolong battery life, avoid completely draining the battery. Recharge the device regularly, especially if it will not be used for an extended period. The built-in battery protection helps prevent deep discharge.
- Storage: Store the compressor in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided storage bag to protect it from dust and damage.

The silicone protection provides a comfortable grip and helps prevent burns from heat.
Troubleshooting
- Compressor does not turn on: Ensure the battery is charged. If using external power, check connections. If the battery is completely drained, it may take a few minutes of charging before the unit responds.
- Compressor runs but does not inflate: Check that the air hose is securely attached to both the compressor and the item's valve. Ensure the valve is not blocked or damaged. Verify that the correct adapter is used.
- Inaccurate pressure reading: Ensure the hose connection is tight. Compare the reading with a known accurate pressure gauge if available. Note that pressure readings can fluctuate slightly due to temperature changes during inflation.
- Compressor stops unexpectedly: The automatic shut-off feature activates when the preset pressure is reached. If it stops before reaching the target, check for overheating (allow to cool down) or low battery.
- Device surface becomes sticky: This can occur over time due to environmental factors. Clean with a damp cloth and mild soap, or consider using a protective cover.
