16. The centrifugal discharge valve may jam because of a foreign body. To clean it, unscrew the
hexagonal screw positioned at the base of one of the dischargers, remove the spring and the ball.
To remove the ball, it may be necessary to “shake” the fan. Clean or replace, whichever is necessary.
17/18 Before carrying out maintenance to the control valve, make sure that the pressure inside the tank
is equal to ZERO. Replace the control valve.
19. Compressors that have deteriorated a great deal that pump oil, may deposit carbon between the
after-cooler tube and the control valve, restricting the airflow and eventually obstructing these
components completely. They must, therefore, be cleaned or replaced.
WARNING: before carrying out such an operation, disconnect the unit from the mains and elimi-
nate the pressure in the tank
20. The motor pulley and the fly wheel must be aligned to prevent deterioration of the side panels of
the belts. If this is not the case, disconnect the unit from the mains and adjust the pulley by
loosening the screw and positioning the pulley in the correct direction.
WARNING: before adjusting the pulley, disconnect from the mains.
21. It is necessary to periodically clean the entry filter, to allow air to pass freely. To clean the filter,
remove the thumb nut, the metallic casing and the filter cartridge. The filter cartridge can be
cleaned by blowing it with an air nebuliser, if not excessively dusty. Filters that are very dirty
should be replaced. NEVER clean the filter with flammable oil, cleaning fluid or flammable solvents.
22. Particular attention should be paid to the oil in the casing as it guarantees correct and long term
function. Check and replace frequently, as indicated in the relevant compressor instructions.
