Maintenance and Troubleshooting
setting on automatic operation as described in the paragraph "Pass from manual to automatic operation".
• Check you have left sufficient free space between the product to pack and the opening of the bag; a limited
space creates folds and bends on the opening of the bag that limits the vacuum level reachable and
prevent the vacuum sensor from starting automatic sealing.
THE MACHINE DOES NOT REACH A CONVENIENT VACUUM LEVEL
• Check you have correctly positioned the opening of the bag between the seals of the vacuum chamber.
• Proceed with auto-diagnosis tests to ensure the machine is working correctly.
• The machine works correctly with original, embossed type bags. Different bags may not work adequately;
check you have used the correct bags.
• Check you have removed all possible roughness that could perforate the bag; the machines create a high
vacuum level with resulting adhesion of the bag to the product, any point or roughness can create micro-
pores in the bag to let air in.
• Check you have left sufficient free space between the product to pack and the opening of the bag; a limited
space creates folds and bends on the opening of the bag that limits the vacuum level reachable.
• Check the seals on the vacuum chamber; in the event of slight liquid suction the seals can harden and get
damaged; in this case you need to change the seals.
Note: hydraulic oil to be used is Omcan item 15713.
