whereas the solenoid valve will bleed the air off the final manifold and head, thus favoring
next compressor start.
A short air blow of some seconds when the compressor stops is therefore a sign of proper
compressor operation (this blow cannot be heard during regular use with door closed). As
soon as pressure reaches the min. allowed value, the compressor will automatically start.
Operating pressure adjustment
Check for optimal operating pressure value of the accessory to be used with the relevant
manual.
Adjust the air pressure at the outlet according to the required value through the pressure
reducing valve 8 (fig.4). Turn the knob clockwise to increase pressure and anti-clockwise to
decrease. The set value is indicated by the pressure gauge 7 (fig.4).It is recommended the
pressure value be zeroed after use so that the pressure reducing valve will not be subject
to earlier wear.
First start-up
Once the compressor has been carefully positioned and connected, it is ready for start-up.
It is recommended this operation - operational test - be performed by a specialized
technician.
Before continuing, make sure that
• mains voltage is the same as voltage mentioned in the machine plate;
• all connections have suitable cross-section cable (see table) and that cables are neither
damaged nor have bare wires;
• wall switch is equipped with suitable fuses (see table);
• oil level is over the minimum level.
After checking the above, proceed as follows:
• Power the wall switch on (Three-phase Pulsar).
Plug the machine (Single-phase Pulsar);
• Start the compressor powering on the control panel switch (20-lt tank) or through the
pressure switch/built-in pressure switch (50-100-lt tank) (fig. 3);
• Allow the motor to run for at least 5 minutes with the air valve open. After that time, close the
valve and make sure the compressor is loading the tank and stops after reaching the max.
pressure value indicated by the pressure gauge 6 (fig, 4).
Never unplug the compressor to stop it but always position either the switch on the pressure
switch body or the wall switch to Off. In this way the compressed air in the head will be bled,
thus favoring next compressor start.
Safety devices
Safety valve on the pressure switch/built-in pressure
switch: bleeds the air off once the max. safety value has
been reached.
Motor thermal cutout (fig.5): in case of motor overheating
due to some troubles, this device will trip, thus cutting the
machine out and avoiding any motor damage.
Allow some minutes (about 5) before manually resetting
the thermal cutout so that the motor can restart.
If the switch trips again on motor restarting, power the
machine off. Unplug the compressor and call an authorized
service center.
