4. MAINTENANCE
Make sure that the plug is removed from
the mains when carrying out
maintenance work on the motor.
The machine has been designed to operate
over a long period of time with a minimum of
maintenance. Continuous satisfactory operation
depends upon proper machine care and regular
cleaning. Before interfering in any way whatsoever
withthecompressor,pleasemakesurethat:
• Theswitchbuttonisinthe“0”positionandthe
power plug is removed from the power socket
• Theairtankisfullydecompressed(both
pressure gauges must be pointed at 0 Bar)
Malfunction
Shouldthemachinefailtofunctioncorrectly,a
number of possible causes and the appropriate
solutionsaregivenbelow:
Air loss
• Maybecausedbyapoorsealofaconnection.
 • Checkallairconnectionsbywettingthem
with a soapy water solution ( Never use the
solution nearby electric connections )
 • Whenthetankisemptyandbeingfilled.
The user might hear a sisseling sound by
the pressure switch. This is normal and
will stop before the compressor reach a
pressure of 1.5 bar
 • Checkifthedrainvalve(14)isclosedwell
The compressor will not start
Ifthecompressorisdifficulttostart,check:
 • whetherthevoltageofthemainscorre-
sponds to that on the specification plate
(fig. 10)
 • whetherelectricalextensioncablesare
being used with a faulty core or length.
 • whethertheoperatingenvironmentistoo
cold(below0°C).
 • whetherthereiselectricitysupply(plug
properly connected, magneto-thermal
fuses not broken).
 • whetherthecarbonbrushesarenotworn
out.
The compressor does not shut off
Ifthecompressordoesnotshutoffwhenthe
maximumpressurehasbeenreached,thesafety
valveofthetankwillbeactivated.Itisnecessary
to contact the nearest authorised Support Service
for the repair.
Repairs and servicing should only be
carried out by a qualified technician or
service firm.
Cleaning
Regularly clean the machine housing with a
softcloth,preferablyaftereachuse.Keepthe
ventilation slots free from dust and dirt.
Ifthedirtdoesnotcomeoffuseasoftcloth
moistened with soapy water. Never use solvents
suchaspetrol,alcohol,ammoniawater,etc.
These solvents may damage the plastic parts.
Drain the tank
Compressing air will cause water in the tank.
Regularly drain the water from the tank to prevent
tankcorrosion(fig16):
• Firstreducethepressureinthetanktill
aprroxially 2 bar by connecting and activating
an air tool .
• Thenslowlyturnthedrainvalve(14)onthe
lower side of the tank open.
• Thewaterinthetankwillnowleakoutofthe
tank
Take care when compressed air is in the tank
because the water can come out with some force.
Recommended pressure max. 1-2 Bar.
Clean the air filter
Itisrecommendedtodisassemblethesuction
filter every 50 operating hours and to clean the
filter element by blowing it with compressed air
(fig.15).Itisrecommendedthatthefilterelement
is replaced at least once a year if the compressor
is working in a clean environment; more often
if the environment in which the compressor is
situated is dusty.
