REMEDY
Maintain the air
supply pressure at a
suitable level, but less
than 7 bar (102 psi)
Adjust the air
pressure suitably
through the
regulator
Remove any
obstructions. (*)
Open the valve
Remove or mix well
The fluid filling
level must be higher
than the inlet
suction pipe. (*)
Dilute the fluid
suitably. (*)
Ensure sufficient air
pressure: eliminate
any other air con-
sumption that might
compromise the air
system
Replace. (*)
