To makethemanual easierto read, thefollowing termshavebeen adopted:
DANGER
The term DANGER is used when failure to comply with the regulations or tampering with the
parts could lead to serious injury or even death.
WARNING
The term WARNING is used when failure to comply with the instructions could cause damage to the
machine and other parts associated with the same or to the surrounding area.
LABELAPPLIED TOTHE COMPRESSORS
To protectexposedpersons orobjects,a specialbookletentitled “SAFETY REGULATIONS” issupplied
withthemachine andmustbe consideredanintegral partofthe Compressor InstructionManual.
Editor’snote: This manualrefers specifically tothe “STANDARD” series ofrefill stationswhich,as later
explained, may be supplied in various arrangements although they all work on the same
operatingprinciple.
Forthis reason,the illustrationsgiven inthe InstructionManualshouldbeconsideredonly
asindications insofar asthey referto just oneversion ofrefill station in the“STANDARD”
series.

The following information must be referred to and applied only when this manual and the
“Safety regulations” manual have been read and their contents have been understood and
assimilated.
VERSIONWITH ELECTRIC ENGINE
- Check whether or not the area where the machine is installed has suitable ventilation
(seechapter 6.1).
- Ifthe machineis installedinaplacewithout therequired characteristicsabove, connecttheairintake
extension(see chapter 6.2.1).
- Connect the refill hoses to the machine (see chapter 6.2.2).
- Connect the switchboard to the mains power supply (see chapter 6.2.3).
- Checkthe level ofthe lubricating oilin the pumpunit (see chapter8.2). Ifthelevel istoolow,turn off
the machine and add or change the oil (see chapter 8.1).
- Turn on the machine using the main switch (see chapter 7.1).
- Checkthe direction ofrotation ofthe motor. If thedirection ofrotation does notcoincide withthe one
shown on the belt guard, turn off the machine and invert the two phases on the main power supply
(seechapter 7.2).
- Checkthe operation ofthe safetyvalve(see chapter9.1).
- Check for wear on the cylinders to be filled (see chapter 9.1).
- Set the pressure switch on the control panel to the refill pressure value given on the cylinder
(seechapter 8.1).
- Fit the hose attachment on the cylinder and check that the taps on the hose are open
(seechapter 9.2).
- Turn on the cylinder tap and start up the compressor (see chapter 9.2).
- When the filling operation has been completed, the compressor is stopped automatically by the
pressure switch, turn off the cylinder and the hose taps.
- Press the pressure bleed button and disconnect the cylinder attachment (see chapter 9.2).

STOPPINGTHE ENGINE
In an emergency, simply move the engine switch to the “OFF” position.
To stop theengine under normalcircumstances:
- turn the accelerator lever in an anti-clockwise direction as far as it will go;
- movethe engine switchto “OFF”;
- movethe fuel leverto “OFF” (ina clockwise direction).
