high working pressure will cause
automatic projection.
5.Electronical control board is
broken.
Description: Pressure sensor is
damaged.
Possible Reason: Inner parts of the
pressure sensor is broken.
Change a new pressure sensor.
Friendly Reminder:
Please thoroughly clean the machine in
time each time after spraying, keep the
inner fluid pump clean, and please store

Turn off the power, wait till the electronical
control board cools down, and change
bigger tip size.
Description: no-load protection
Possible Reason: coatings in the
bucket is empty, the machine will
automatically stop running to protect
the V-packings from fast wear-out.
Turn off the power and then turn on the
power, or turn the pressure regulator to
minimum and then reset the pressure.
Description: Motor block protection
Possible Reason:
1.Too low voltage and using too
small tip size at the same time.
2.Inner parts of the fluid pump is
damaged.
1.Check the voltage and change bigger tip
size.
2.Check if the inner parts of fluid pump is
damaged, if yes, change the fluid pump.
Description: Communication error
of the electronical control board.
Possible Reason: Static electricity
interferes the communication inside
the electroncial control board.
Turn off the power, after the display screen
is completely off, turn on the power, if it still

new electronical control board.
Display error code (???u)
Alarm for checking the power
voltage
Possible Reason: When the
voltage is too low or the machine is
not running smoothly, this error
code will occur due to not enough
input power supply.
1.Check the power cable, check if the
patch board is loosened.
2.Change bigger tip size and retry.
3.Turn off the power and adjust the
pressure regulator to minimum, after the
