The pressure indicator shows the current operating pressure of
the sprayer. It has three different indications: blinking yellow,
solid yellow, and solid green.

When the pressure indicator is blinking yellow, the sprayer is
operating between 0 and 1.4 MPa (14 bar). A blinking yellow
pressure indicator means:
• Thesprayerispluggedinandturned“ON”

When the pressure indicator is solid yellow, the sprayer is
operating between 1.4 MPa (14 bar) and 12 MPa (120 bar). A
solid yellow pressure indicator means:
• Thesprayerisattheproperpressuresettingforspraying
stain, lacquer, varnish, and multi-colors
Solid Green
When the pressure indicator is solid green, the sprayer is
operating between 12 MPa (120 bar) and 23 MPa (230 bar). A
solid green pressure indicator means:
• Thesprayerisattheproperpressuresettingforspraying
oil-based and latex house paints
• Thesprayerisoperatingatpeakperformanceatahigh

• Ifthepressureindicatorgoestosolidyellowwhenthe
pressure is set so that it starts at solid green, it indicates
one of the following:
a.  — when spraying with latex or at
high pressure the solid yellow appears. This means the
tip is worn and needs to be replaced.
b. Tip Too Large — when a tip that is too large for the
sprayer is put in the gun, the pressure indicator will turn
from solid green to solid yellow.
c. — if a solid yellow pressure
indicator appears when using a new tip and the
pressure is set at maximum, service may be required
(worn packings, worn piston, stuck valve, etc...).

The Service indicator is on when the motor is commanded to run.
This indicator is used by service centers to troubleshoot motor
problems.
