10 RECOMMENDATIONS FOR THE PROPER OPERATION OF THE AIR
COMPRESSOR
Consult this user's and maintenance manual before starting the machinery.
10.1 Before starting
Strictly follow the instructions outlined in the manual:
1) Level the machine by adjusting the support foot or the wheel; no incline greater than 15° is allowed.
2) Check that the battery cables are connected to the battery correctly; if the cables need to be connected, use
care and verify that the cable coming from the starter motor is connected to the positive pole (+) of the battery
and that the ground cable is connected to the negative pole (-) of the battery.
3) Check the fuel level in the tank. USE DIESEL FUEL ONLY.
4) Check the level of the engine oil. As related to the types of lubricant and correct quantities, comply with the
recommendations contained in the engine manufacturer's user's and maintenance manual included with the
machinery documentation.
5) Check the oil level in the compressor. Stop the machine and allow it to sit for at least 5 minutes, allowing the
lubricant to return to the oil mist separator tank. Before unscrewing the dipstick, level the machine, making
sure that there is no pressure in the system (the pressure gauge shall indicate 0 bar/psi).
a) Remove and clean the dipstick.
b) Thoroughly screw the dipstick back in and then remove it again to verify that the lubricant level is between
the two engraved marks (min. and max. level).
c) Top off the oil if required; the level must never exceed the max. mark.
d) Exclusively utilize the types of oil recommended in this user's and maintenance manual.
