operating on the knob with the valve open (pulling it up and turning it in a 

clockwise  direction  to  increase  pressure  and  counterclockwise  to  reduce 

this) (

fig. 7

). Once you have set the value required, push the knob down to 

lock it.

•  The  value  set  can  be  checked  on  the  gauge  (for  versions  equipped  with 

this, 

fig. 8

).

• 

Please  check  that  the  air  consumption  and  the  maximum  working 

pressure  of  the  pneumatic  tool  to  be  used  are  compatible  with  the 

pressure  set  on  the  pressure  regulator  and  with  the  amount  of  air 

supplied by the compressor

.

•  When you have finished working, stop the machine, pull out the plug and 

empty the reservoir.

MAINTENANCE

3

•  The service life of the machine depends on maintenance quality.

• 

PRIOR  TO  ANY  OPERATION  SET  THE  PRESSURE  SWITCH  TO  THE 

OFF POSITION, PULL OUT THE PLUG AND COMPLETELY DRAIN THE 

RESERVOIR.

•  Check  that  all  screws  (in  particular  those  of  the  head  of  the  unit)  are 

tightly  drawn  up  (

fig.  9

).  The  check  must  be  carried  out  prior  to  the  first 

compressor starting.

•  Clean  the  suction  filter  according  to  the  type  of  environment  and  in  any 

case  at  least  every  100  hours.  If  necessary,  replace  the  filter  (a  clogged 

filter impairs efficiency while an inefficient filter causes harsher wear on the 

compressor

 (figures 10a - 10b)

.

•  Change  the  oil  after  the  first  100  hours  of  operation  and  subsequently 

every 300 hours. Check the oil level periodically.

•  Use 

API  CC/SC  SAE  40

.  (For  cold  climates, 

API  CC/SC  SAE  20

  is 

recommended).  Never  mix  different  grade  oils.  If  the  oil  changes  color 

(whitish  =  presence  of  water;  dark  =  overheated),  it  is  good  practice  to 

replace the oil immediately.

•  After  topping  up,  tighten  the  plug  (

fig.  11

)  making  sure  that  there  are  no 

leaks during use. Once a week, check the oil level to assure lubrication in 

time (

fig. 6a

).

•  Periodically  (or  after  completing  work  if  for  more  than  an  hour),  drain  the 

condensate  that  forms  inside  the  reservoir  due  to  the  humidity  in  the  air 

(

fig. 12

) in order to protect the reservoir from rust and so as not to restrict 

its capacity.

•  Periodically, check the tension of the belts which must have a flexion (f) of 

around 1 cm (

fig. 13

).

*

  Spent  oil  and  condensate 

MUST  BE  DISPOSED  OF

  in  compliance  with 

protection of the environment and current legislation.

The  compressor  must  be  disposed  in  conformity  with  the  methods 

provided for by local regulations

POSSIBLE FAULTS AND RELATED PERMITTED REMEDIES

4

Request the assistance of a qualified electrician for operations on electric components (cables, motor, pressure switch, electric panel, etc).

FAULT

CAUSE

REMEDY

Air leak from the valve of the pressure switch.

Check valve does not perform its function 

correctly due to wear or dirt on the seal.

Unscrew the hex-shaped head of the check 

valve, clean the housing and the special rubber 

disk (replace if worn). Re-assembler and tighten 

carefully (

figures 14a-14b

).

Condensate drainage cock open.

Close the Condensate drainage cock.

Rilsan hose not inserted correctly in pressure 

switch.

Insert the Rilsan hose correctly inside the 

pressure switch 

(fig. 15)

.

Reduction of efficiency, frequent start-up. Low 

pressure values.

Excessively high consumption.

Decrease the demand of compressed air.

Leaks from joints and/or pipes.

Change gaskets.

Clogging of the suction filter.

Clean/replace the suction filter 

(

figures 10a-10b

).

Slipping of the belt.

Check belt tension 

(fig. 13).

The motor and/or the compressor overheat 

irregularly.

Insufficient ventilation.

Improve ambient conditions.

Closing of air ducts.

Check and if necessary clean the air filter.

Insufficient lubrication.

Top up or change oil

(

figures 16a-16b-16c

).

After an attempt to start the compressor, it stops 

due to tripping of the thermal cutout caused by 

forcing of the  motor.

Start-up with head of the compressor charged.

Release the compressor head by using the 

pressure switch push button.

Low temperature.

Improve ambient conditions.

Voltage too low.

Check that the mains voltage matches that of 

the dataplate. Eliminate any extensions.
