6.2 TIPS FOR THE STARTING PHASE
After carrying out the topping-up operations for the Pack Smart, start the machine and switch it off
after 2 seconds at the latest so as to load some air.
The machine will not load air, if the air-end shaft does not turn in the right direction as indicated by
the arrow on the case (see point 5.1 in the Runbook).
If the direction of shaft rotation is not correct, you have to act on it through the motor electrical
connections (see chapter 5.1).
Start the machine again if you want to check the right direction of rotation.
The direction of shaft rotation can be checked as follows:
- For belt drive, check the direction of pulley rotation. It must be the same as the direction
indicated by the arrow on the air-end case.
- For spring drive, check the rotation direction of flexible coupling through the slits of bell
housing. The direction of rotation of flexible coupling must be the same as the rotation
indicated by the arrow on the air-end case.
- For gearing drive, check the rotation direction of the electric motor cooling fan. It must be
the other way round compared to the arrow on the air-end case.
6.3 LONG PERIODS OF INACTIVITY OF THE PACK SMART
If during the life of the compressor there are long periods of inactivity of the same (> 1 week) we
recommend to start the machine for about 5 minutes in idle mode. This will allow an optimal
lubrication of the system.
6.4 INSTRUCTIONS TO FOR A MINIMUM PRESSURE VALVE
CALIBRATION
IF YOU WANT TO INCREASE THE
CALIBRATION OF A MINIMUM PRESSURE
VALVE:
Unscrew the stop nut (B2) and screw the pressure
control screw slowly (B). When you reach the
desired pressure, screw the stop nut (B2) so that
the result is fixed (picture 11)
IF YOU WANT TO DECREASE THE
CALIBRATION OF A MINIMUM PRESSURE
VALVE:
Unscrew the stop nut (B2) and unscrew the
pressure control screw slowly (B). When you reach
the desired pressure, screw the stop nut (B2) so
that the result is fixed. (
