• Orange indicator ON (30% < battery capacity<60%)
• Red indicator ON (battery capacity<30%).
  Charging is required.

Charging State
Fully charge the air compressor before first use. Connect the charging cable to a SV USB charger (sold separately) to charge the HOTO Portable Electric Air Compressor.

Battery level indicator while charging

• Red indicator flashing (flash every 3 seconds): charging
• White indicator ON: fully charged
  Note: The air compressor cannot be used while charging.

Turning On
Press the “Power” button for two seconds, and the air compressor will start inflating automatically. Short press again and the air compressor will start working. If the air compressor is not operated for 3 minutes after power-on, it will automatically power off.

Connecting the high-pressure air hose to the air valve
Schrader valve

Mountain bicycles, electric bicycles, motorcycles, and cars will be equipped with a “Schrader valve”.

• Inflate: Directly connect the air compressor to a “Schrader valve” for inflation.
• Deflate: Use an appropriate tool to press the needle valve adapter inside the air valve for deflation.

Presta valve adapter

Road bicycles and certain mountain bicycles may use a “Presta valve” Screw the “Presta valve” onto the “Schrader valve” and connect the “Presta valve” to the tire.

• Inflate: Unscrew the Presta valve, connect the “Presta valve” for inflation. After inflation, screw on the valve.
• Deflate: Unscrew the Presta valve, and press the screw for deflation.

Needle valve adapter

The “needle valve adapter” should be used to inflate balls like basketballs and footballs.

• Inflate: Screw the “needle valve adapter” onto the “Schrader valve”, and insert the needle into the air hole for inflation.
• Deflate: Insert the “needle valve adapter” into the valve of the ball for deflation.

Adapting valve

Swimming ring and other inflatable items should use a “Adapting valve” when inflating.
Detecting Air Pressure
The current air pressure will automatically be displayed after the air hose is connected to an item while the air compressor is powered on.

Determining the Correct Air Pressure

To ensure safety and prevent injuries from bursting items due to over- inflation, always refer to the user manual or relevant directions accompanying the item to be inflated before inflation, in order to determine the correct air pressure.

Tires

The recommended air pressure of tires for cars, bicycles, and motorcycles is indicated on the sidewall of the tire.
The recommended tire pressure for cars is also indicated on the driver’s side door jamb. For details concerning load carrying capacity and recommended air pressure, refer to your vehicle’s instructions or manual.

Balls
The recommended air pressure for footballs, basketballs, volleyballs, and other balls is indicated near the ball’s air valve.

Presetting Pressure

Mode toggling

| Press the “Numeric Knob’ 5 to toggle between the five inflation modes below. Select the preferred air pressure unit before inflating. Press and hold the “Numeric Knob” to toggle between psi and bar.
---|---
| No mode indicator ON: User-specified pressure presetting (pressure value and unit will be saved)
Adjustable range: 3-lS0psi
| Indicator ON in ball mode: default 8psi
Adjustable range: 4-16psi
| Indicator ON in bicycle mode: default45psi
Adjustable range: 30-65psi
| Indicator ON in motorcycle mode: default 2.4bar
Adjustable range: 1.8-3.0bar
| Indicator ON in car mode: default 2.Sbar
Adjustable range: 1.8-3.Sbar

Adjusting the Preset Pressure

After selecting the scenario mode, turn the “Numeric Knob” clockwise to”+” and counterclockwise to”-” to adjust the preset pressure value.
When adjusting a preset pressure, the number flashing indicates the target pressure, and after flashing for 5s, the number being “ON” indicates the real- time pressure.

Light

Short press the “Light ON/OFF” button to turn the air compressor’s light on/off. The light makes it easy to see in the dark when you have any operations, such as connecting the air compressor to a valve.

Inflating
Start Inflating
After power-on, short press the “Power” button to start inflation, and the digital display will show the real time pressure change during inflation. When inflating, the air compressor will generate an operating noise of 75-80dB. Please take  appropriate precautions to protect your hearing.
Stop Inflating
Once the preset pressure has been reached, the air compressor will automatically stop inflating. The air compressor can also be stopped at any time while inflating by short pressing the “Power key”.

Caution
Items such as balloons, beach balls, and swim rings cannot be automatically inflated because they have an air pressure requirement below the air compressor’s minimum pressure range. They can not automatically stop inflating through  the preset pressure and should be used with caution.
Battery and Battery Life
The battery of the air compressor will last about 30 minutes on a full charge running without a load at an ambient temperature of 25 ° C. Using the air compressor under a heavy load or at higher ambient temperature may reduce its battery life.
Removal of Air Hose
The air compressor’s air hose may get very hot after inflating. To prevent injuries, exercise caution when removing it from a valve. Some air may leak out of the valve when removing the air compressor. To avoid air leakage, quickly remove the air hose from the valve.
OFF
After power-on, press and hold the power button for about 2 seconds to power off the air compressor.
If the air compressor is not used for 3 minutes, it will automatically power off.

Precautions

• This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.
• The air compressor has a built-in non-removable lithium battery and should never be exposed to fire or improperly disposed of. The exposure of the lithium battery to extreme heat, impact or water may cause fire, spontaneous combustion, and even explosion. Do not expose the air compressor’s battery to high temperature conditions, such as leaving it in a car in direct sunlight.
• The air compressor should not be stored attemperators below -10°C or over 45°C. Exposure to extreme heat or cold will shorten the air compressor’s service life and damage the built-in battery.
• Leaving the air compressor unused for a longtime may harm the battery, it is recommended to charge the air compressor at least once every three months.
• The air compressor has a built in DC motor which may produce electrical sparks when running. Thus, it should never be used in flammable or explosive environment.
• If the air compressor makes an unusual noise while running or starts to overheat, turn it off immediately.
• Always make sure the correct air pressure unit is selected before setting the air pressure to prevent accidents such as tire burst. Common unit conversion: lobar=l4.Spsi, lobar=l00kPa.
• Always monitor the air compressor during usage and never leave it unattended when using it to avoid over-inflating when there is no preset pressure.
• Only use the air compressor in a clean and dry environment. Intrusion of dirt and dust may cause damage to the air compressor. The air compressor is not waterproof and should never be rinsed with water.

Troubleshooting

sufficient.
2. Check whether the air hose is leaking.
3. Check whether both ends of the air hose are securely connected.
4. Check whether the item that is being inflated is leaking.
Inflation failure after power-on| 1. Check whether the air compressor’s battery level is sufficient.
2. Check whether the current tire pressure exceeds the preset one.
Failure to increase or decrease the preset pressure| Make sure the air compressor is set to the correct mode. Select the free mode with no icon ON to adjust the preset value within a range of 3 – 150 psi.
Normal inflation but the pressure displays zero| The pressure of low-pressure inflatables including balloons is too low to be measured.
Air compressor power-off after connecting the air hose to a valve| Press and hold the “Power/start-stop key” button to power on the air compressor again.
Air leakage when connecting the air hose| Make sure the air hose is securely connected.
Different color of the battery level indicator when inflating and on standby| The lithium battery’s voltage level significantly drops when discharging power, causing the battery level indicator to have a different color when inflating compared with standby state. This is normal.
The display shows E01| The voltage from USB connector is abnormal. Please use a 5V charger.
