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).

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.

Replacing/topping up oil

The compressor has been supplied with synthetic
oil “SAE 10W30”. It is recommend to fully
replace the oil of the pump system within the first
100 operating hours.

• Unscrew the drain plug (gauge) (13) on the

sump lid, let all the oil run out and screw back
the plug (fig. 17).

• Fill the oil via the upper hole of the sump lid
