to access the regulator. Remove the brass hex plug,
spring, and poppet from the regulator. Clean the
poppet and reinstall the poppet, spring, and plug.
No lubricant flow to

Tank pressure may be too low. Minimum operating
tank air pressure is 0.83bar (12psi).
Hose connector may not be pushed fully into the fluid
outlet fitting on the rear panel of the controller. Ensure
connector is firmly seated.
Check fluid hose for kinks.
Valves do not turn on Supply pressure to controller must be at 4.1bar
(60psi).
Lubricant flows but
valve does not spray
Air cap may be clogged. Be sure oil tank filter is clean.
Remove air cap and clean the inside of the air cap
and the outside of the nozzle. Refer to “Spray Valve
Maintenance” on page 25.
Nozzle air pressure regulator may be set too low.
Increase pressure as needed. Normal working range is
within 0.55–1.03bar (8–15psi).
Valve drips after

Dripping can be caused by improper seating of the
needle in the nozzle. Clean the needle and nozzle, and
replace any worn or damaged parts.
Ensure nozzle is tight to seat the needle properly.
