Obligations in the event of malfunctioning and/or potential
dangers
The operators must inform their direct seniors of any deficiency and/or potential
dangerous situation that should occur.
6.1 - User obligations
The user must inform the manufacturer immediately if any defects and/or
malfunctioning of the accident-prevention system are detected, as well as any
presumed dangerous situation of which he becomes aware.
It is prohibited for the user and/or third parties (excluding duly authorised
manufacturer’s staff) to make any type or entity of modifications to the machine
and its functions, as well as to this technical document. In the event of
malfunctioning and/or dangers, owing to failure to respect the afore-said, the
manufacturer is not liable for any consequences. We recommend you request any
modifications from the Manufacturer.
7 Troubleshooting
7.1 - Troubleshooting
1 After having connected the master switch, the machine does not start:
a) Check that the plug is well inserted into the socket and, if necessary, control the
contacts inside the plug itself.
b) Check that on lowering the dome, the micro switch positioned on the rear below
the left fixing hinge, is excited.
2 The machine operates regularly, but the package is not sealed when the
dome is opened
a) Lift the Teflon and check that the resistance is not interrupted and it is blocked
on the lateral clamps.
3 If the machine does not achieve an excellent vacuum
a) Close the dome and disconnect the line when a negative pressure of about 90%
has been reached. Check whether the vacuum percentage indicated on the
display remains fixed or decreases.
- In the first case, there are no leaks, therefore the problem has another source
(pump vanes, oil replacement).
- In the second case, there is the presence of air infiltration into the dome:
• Check the membrane below the sealing bar, checking that it has no holes or
is ripped
• Check the integrity of the sealing gasket positioned under the lid; if the
afore-mentioned pieces must be replaced, request them directly from the
authorised dealer.
