Problem
Slow inflation speed
Air compressor turns on but
does not inflate
Unable to increase or
decrease the preset
pressure
Air compressor inflates
normally but the
displayed pressure is zero
Air compressor already
turned off after connecting
the air hose to a valve
Air leaks out when
connecting the air hose
Color of the battery level
indicator is different
when inflating compared to
standby state
1. Check whether the air compressor's
battery level is 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.
1. Check whether the air hose is removed
from its compartment before inflating.
2. Check whether the air compressor's
battery level is sufficient.
3. Check whether the pressure of the item
that is being inflated exceeds the preset
pressure.
Make sure the air compressor is set to the
correct mode. Manual mode has a blank
display without any icons and allows you to
adjust the preset value within a range of 3 -
150 psi.
The pressure of low-pressure inflatables
including balloons is too low to measure.
Press and hold the Start/Stop button to turn
the air compressor on again.
Make sure the air hose is securely
connected.
The lithium battery's voltage level
significantly drops when discharging power,
causing the battery level indicator to have a
different color when inflating compared to
standby state. This is normal.
