ded, the piston.
The unit does not
maintain good spra-
ying pressure
Worn or defective spraying nozzle
Replace the spraying nozzle.
Packings and/or piston worn

Control settings
Make sure that the power plug on the device is plugged
in. Make sure that the ON/OFF switch is set to ON
position and that the pressure regulator button is fully
clockwise (max. pressure).
Pressure regulation unit (controller
card)
If the power display is not lit after checking the control
settings and the power source, you must replace the
pressure control unit.
Motor
Remove the cover on the carbon brushes and switch the
device on. Set the potentiometer to maximum pressure
and check the DC voltage on all the brush connectors.
The voltage should be more than 80 V (DC).
If DC voltage exists, switch the device off and unplug
the power plug. Make sure that the brushes contact the
rotor. Replace the brushes if their length is below 12.7
mm. If the brushes are OK, replace the motor.
If there is no DC voltage, see pressure sensor.
