g) The compressor has not been unloaded and there is back
pressure on the piston. Dismount and check unloader valve (fig.
9). The back pressure may be due to a leaking non-return valve
causing the compressed air in the receiver to leak back into the
compressor motor. Dismount the non-return valve and clean or
change O-ring (fig. 10).
h) Capacitor defective.
2. Compressor operates, but pressure does not increase in
tank (or increases too slowly):
a) The cap on the intake tube has not been removed and repla-
ced by the intake filter (fig. 2).
b) Intake filter is clogged. Replace.
c) Leaks in fittings, tubes or pneumatic equipment. Check with
soapy water. Pressure drop is not to exceed 1 bar per hour.
d) Clogged non-return valve or pressure pipe. Clean or replace
the parts (fig. 10).
e) Air leaks from the unloader valve when the compressor is
operating. Check or replace the unloader valve (fig. 9).
f) Defective valve plate. Contact your SILVER-LINE distributor.
3. Loud noise from compressor:
a) Most likely broken suspension spring(s). Replace the spring
and ensure that motor position is horizontal.
b) The internal pressure pipe touches the rib cover or the cylin-
der block. Dismount the rib cover and bend the pressure pipe
away.
4. Compressor gets very hot and/or uses a lot of oil:
a) Incorrect oil level. The level must appear in the oil level glass
(fig. 5).
b) Wrong oil has been filled in the compressor. Use only genui-
ne SE-32 synthetic lubricant which has the correct viscosity.
c) Leaks. See point 2c.
d) Clogged intake filter. See point 2b.
e) Too high ambient temperature. Do not install the compressor
in a cabinet unless adequately ventilated (fig. 1).
f) The compressor is overloaded (i.e. it is operating more than
50% of the operation time). Contact your SILVER-LINE distribu-
tor.
5. Compressor starts when no air is being used:
a) Leaks. See point 2c.
6. Compressor starts and stops more frequently than usual:
a) Condensate in the air receiver. Empty the receiver by means
of the drain cock (fig. 6).
b) Leaks. See point 2c.

Receiver for compressed air
See name plate
Tubes, etc. must be made of
suitable materials.
Observe the working
temperature of the receiver.
Ensure that sufficient room for
inspection/maintenance is
available in a horizontal
position.
The receiver must be kept in a
horizontal position.
The surface treatment must be
maintained as required.
Internal inspection at least
every 5 years.
Drain moisture at least once a
week.
No welding must be made on
pressurized parts.
Ensures that PS will not be
exceeded.
Never adjust to a higher
pressure than PS.
The capacity of the valve must
be calculated in accordance
with the volume of air supplied
by the compressor.
(PS = Maximum working
pressure of the receiver)
