Risk of injury from pressurized components. Turn off inlet

air pressure and bleed off remaining pressure before dis-

assembly.

1. Turn regulator knob counterclockwise until it

stops.

2. Unscrew the bonnet from the regulator body,

remove adjusting screw and nut, then the

regulating spring,

slip ring, and diaphragm. Unscrew the valve seat

and o-ring assembly using a screwdriver. Then

remove the valve and valve spring.

OPERATION

Binks models 85-448, 85-449 and 85-450 regulators

are flow-thru regulators offering virtually no

restriction for spray painting applications.

Efficient, low flow, regulated parts allow for easy

control of cup (fluid) pressure and/or rotary agitator

speed.

The following conditions must be observed:

1. Do not exceed 100 PSI inlet pressure.

2. When reducing the regulator setting, it is

necessary to relieve fluid supply cup of its

previously set pressure.

IT IS THE RESPONSIBILITY OF THE EMPLOYER TO PROVIDE THIS INFORMATION TO THE OPERATOR OF THE EQUIPMENT.
