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.
25.6 CLEANING OR CHANGING THE FILTER SUCTION PANEL
The prefilter panel guarantees a good air filtration in both ventilation and compression; in this way the internal filters do not become
easily obstructed.
Procedure to be followed for changing the prefilter panel:
1. Stop the machine with the stop pushbutton on the electronic board.
2. Switch off the power: turn the isolating switch to “0” position.
ATTENTION: HOT PARTS INSIDE.
3. Remove the grille protection panel.
4. Remove the suction filter panel.
5. Clean the suction filter panel with a jet of air or wash it with water:
do not use solvents
6. Once the operation has been completed, reassemble the grille and the suction filter panel.
7. If the suction filter panel is replaced, dispose of the old filter in conformity with the local regulations in force.
25.7 AIR-OIL
RADIATOR
The compressor is provided with a combined radiator for oil and for compressed air, fitted in a vertical position. It is cooled by the
air which the electric fan, situated above it, takes in and expels from the machine.
When the radiator is dirty or clogged, it does not exchange heat correctly and must be cleaned.
Procedure to be followed to clean the radiator:
1. Stop the machine with the stop pushbutton on the electronic board.
2. Switch off the power: turn the isolating switch to “0” position and block it with the padlock
ATTENTION: HOT PARTS INSIDE.
3. Wait until the compressor has completely cooled down.
4. Remove the radiator cleaning panel.
5. Clean the radiator with a jet of water and wash it with water and detergent if necessary;
do not use solvents
as they could damage
it.
25.8 THERMOSTATIC
VALVE
The thermostatic valve is used to control the system oil temperature. When the machine is cold the oil by-passes the radiator and goes
straight to the screw. When the oil reaches a certain temperature of about 71°C, the thermostatic valve causes the oil to be cooled
through the radiator, thus avoiding condensation phenomena in the tank.
25.9 SAFETY
VALVE
The safety valve is inspected and calibrated by the manufacturer in conformity with the regulations in force.
The tests of operation of the safety valve must be carried out by authorized personnel.
25.10 MOTOR LUBRICATION
The motor supplied with this model is lubricated for life.
Keep the motor clean and ensure good ventilation, periodically checking the suction grille.
For other specifications or requests, apply to the nearest service centre.
