alcohol, solvent or glass-cleaners since
they can affect the mechanical properties
of the material and break it. If you
appreciate a crack in the cover, stop the
machine and call the authorised technical
service for repairs; there is a risk of cover
breaking.
-In the event the power cable should get
damaged and have to be replaced, the
repair may only be done by a SAMMIC
approved assistance service.
-Before cleaning, repairing or checking the
machine, you must unplug the machine
from the mains.
-The noise level of a machine in operation,
as measured at a height of 1.6m and a
distance of 1 metre, is
Background noise: 32 dB(A).
Oil change
The oil level must be checked weekly. It
should not be below 3/4 of the oil
indicator. Complete the level, if necessary.
Oil must be changed after the first 100
working hours. Afterwards, change oil
every 500 working hours approximately or
at least every 6 months, as well as each
time oil is found to be emulsified. The
accumulated working hours are displayed
when the machine is switched on. To
change oil, unscrew the draining plug and
let the used oil drain out. To fill the pump
with oil, follow the instructions given in the
relevant section.
On pumps with outputs from 40m³/h
upwards, replace the oil filter at the same
time. This filter is of the type used in cars,
as per ref: AWS2, thread 3/4.
The exhaust filtre must be changed every 4
oil changes or on detecting either oil leaks
or oil mist at the escape.
On turning on the machine when the pump
has been working for a total of 500 hours,
the indicator will display 50 and will be
flashing for 10 seconds, indicating that oil
must be changed. During this lapse of
time, the machine will not start, even if the
cover is lowered.
Once oil has been changed, reset the pump
working time according to the following

sequence:
-With the cover open, press STOP. The
vacuum pump will start.
-Lower the cover. The machine will start
and perform a normal cycle.
-Once the vacuum process has started,
press the STOP button quickly. At this
moment, the working time has been reset
to 0. Allow the machine to complete the
cycle.
-Switch the machine off and on, to check
that the working hour display shows 0.

75 dB(A).
There are three possible configurations of
the electronic board, according to the
machine in which it is fitted.
Configuration "0": Continuous duty, self-
standing machines (V-641 and V-821).
The pump remains on as from the time the
main switch is pressed. This configuration
is intended for machines to be installed in
cold rooms and refrigerating chambers.
Because the pump is on continuously, the
machine is kept hot, which guarantees its
proper operation.
Configuration "1": Discontinued duty, self-
standing machines (V-641 and V-821).
The pump is on only during the vacuuming
and sealing stages.
Configuration "2": Discontinued duty,
desktop machines (V-204, V-253, V-410,
V-421 and V-426). The pump is on only
during the vacuuming stage.

object. At this moment, the test process
starts: the electronic board activates
each output (Motor, Sealing solenoid
valve, etc.) for one (1) second and its
associated LED on the board should
then turn on. Next to each LED, there is
a text identifying the component being
tested.
4- On completion of the test sequence, the
display
indicates

stage, the pump working time counter
will be zero-reset.
5- In

to
change
configuration, press the Incrementer or
Decrementer key until the required
configuration value is shown.
6- To exit the test mode and save the new
configuration, switch the machine off. If
you lower the cover before exiting the
test mode, the machine will not start. In
the event that the working time counter
has been reset, you can read the new
value on the display when the machine
is switched on again.
The electronic board has a function testing
feature as an aid to troubleshooting in the
event of a machine failure.
Execute steps 1, 2 and 3 described in the
previous section. If any component fails to
work during the test, proceed as follows:
-Verify that the component is connected
correctly and is energised. If this is OK
and the component still fails, replace it by
a new one.
-If the component is not energised, check
the voltage at the output of the electronic
board when the associated LED is on. If
there is no voltage, change the electronic
board.
