Pressure Relief Procedure
WARNING
The accessory remote pressure pot remains
pressurized until pressure is manually relieved.
To reduce the risk of serious injury from pressur-
ized fluid or accidental spray from gun, always
relieve pressure in the pressure pot before loos-
ening or removing the cover. Also, relieve pres-
sure if the fluid nozzle clogs; and before
cleaning, checking or servicing equipment.

3 Remote Pressure Pot: Turn out pressure relief
knob (113) one turn. Wait until pressure is
completely relieved before removing cover. Close

CAUTION
If the 2-quart remote pressure pot is accidentally
tipped over or held at too great of an angle, fluid may
leak into air regulator and cause damage. Take pre-
cautions to avoid this. If fluid does get into regulator,
clean immediately.
CAUTION
Only hand-tighten pressure pot cover. Excessive tight-
ening may damage cover gasket.
Note: Always spray with the least amount of pot pres-
sure required to provide the desired spray pattern and
rate of application, typically 10 psi. Spraying at pot pres-
sures higher than necessary wastes paint and can result
in an orange peel finish.
