25.2 CHECKING AND TOPPING UP THE OIL LEVEL
Indicates the amount of oil in the oil reservoir. Read oil level only when unit is stop. In the operation the oil level will fluctuate as the
compressor loads and unloads. Check oil level only when compressor
is stop
and add oil only when the level is below the minimum
(indicator in the red zone fig. 11).
BEFORE REMOVING THE OIL CAP AND/OR THE OIL FILTER, STOP THE COMPRESSOR AND
ENSURE THAT IT IS COMPLETELY DEPRESSURIZED. IF IT IS NOT COMPLETELY
DEPRESSURIZED IT MAY BE VERY DANGEROUS AS IT CAN CAUSE EVEN MORTAL INJURY..
This must be done when the oil level visible in the plastic pipe is below the recommended oil level.
N.B.
The value must be read with the unit is stop.
BE SURE THE UNIT IS COMPLETELY OFF AND THAT NO AIR PRESSURE IS IN THE OIL
RESERVOIR. ADD OIL AS REQUIRED TO RETURN THE OIL LEVEL TO THE CORRECT POSITION.
TOP UP TO THE REQUIRED LEVEL. DO NOT OVERFILL.
Repeated topping up with oil between one change and the next indicates excessive oil consumption; it is recommended to have the
compressor checked by a skilled technician to remove the cause.
AIR AND OIL UNDER HIGH PRESSURE CAN CAUSE SERIOUS INJURY. SHUT DOWN THE
COMPRESSOR AND RELIEVE THE SYSTEM OF ALL PRESSURE BEFORE REMOVING VALVES,
CAPS, PLUGS, FITTINGS, BOLTS AND FILTERS.
25.3 CHANGING THE OIL FILTER
The oil filters fitted on the compressors have a by-pass valve inside them. If the cartridge is particularly clogged, the valve prevents
oil circulation being blocked, that is it still guarantees the circulation of oil on the screw.
IMPROPER OIL FILTER MAINTENANCE WILL CAUSE DAMAGE TO EQUIPMENT. REPLACE
FILTER ELEMENT AS INDICATED IN THE “MAINTENANCE” SECTION. MORE FREQUENT
REPLACEMENT COULD BE REQUIRED DEPENDING ON OPERATION CONDITIONS. A FILTER
ELEMENT LEFT IN SERVICE TOO LONG MAY DAMAGE EQUIPMENT.
Procedure to be followed for changing the cartridge:
ATTENTION: HOT PARTS INSIDE.
