4. Fill the oil cup with EasyGlide(Fig. 5). Do not use too much
EasyGlide, i.e. ensure that no EasyGlide drips into the coat-
ing material container.

4.2 Control Panel Indicators

The following is a description of the control panel indicators.

Pressure Indicator
The pressure indicator shows the current operating pressure of
the sprayer. It has three different indications: blinking yellow,
solid yellow, and solid green.
Blinking Yellow
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"
• The sprayer is at priming pressure (little or no pressure)
• It is safe to move the relief valve between positions
• It is safe to change or replace the spray tip
If the pressure indicator begins blinking yellow
i
when the pressure control knob is set at a
higher pressure and the relief valve is in the
SPRAY position, either the spray tip is worn or
the sprayer is in need of service/repair.

Solid Yellow
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
• 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. Tip Wear Indicator — 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. Fluid Section Wear — 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...).
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
pressure setting
Service Indicator
The Service indicator is on when the motor is commanded to
run. This indicator is used by service centers to troubleshoot
motor problems.
