Chapter 6. Safety standards

6.1. Warnings

Do not touch the sealing blade (16) immediately after sealing (figure 6.1.A page 52).
Danger of burns due to hot blade.
Do not touch the vacuum pump (23) just after a working cycle (figure 6.1.B page 52).
Possibility of burning due to the high temperature the pump may reach.
USE PROTECTION GLOVES!
Do not seal if the sealing wire is broken.
Replace it immediately.
In case of a power failure during a working cycle when the cover is closed, do not use any tool in order to
force its opening. Wait for the power supply to be restored (figure 6.1.C page 52).
Before any working cycle make sure that the closing hook (19) will not prevent the operator from closing
the cover correctly (figure 6.1.D page 52).
Possibility of breaking the cover.
Never use gaseous mixtures in presence of oxygen in a percentage higher than the atmospheric
one (~ 19%).

Chapter 7. Ordinary maintenance

7.1. Precautions for ordinary maintenance interventions

ORDINARY MAINTENANCE, MUST BE EXECUTED BY QUALIFIED STAFF APPROPRIATELY TRAINED.
Before any routine maintenance switch the machine off by acting on the main switch and remove
the plug from the mains socket.
Disconnect gas plant.
It is recommended to use protection gloves during maintenance operations!

7.2. Cleaning of the sealing bar

Use a dry cloth to remove any film residue on the sealing bar (16). Carry out this operation just after any sealing cycle.
Residues are still hot and may be easily removed (figure 7.2. page 52).
7.3. Replacement of the Teflon and the sealing blade
Before replacing teflon and the sealing blade wait for the machine to be properly cooled.
•
Remove the sealing bar (16) from its seat (figure 7.3.A-7.3.B page 52)
•
Remove the teflon adhesive tape
•
Unscrew the nuts fastening the blades to each end of the sealing bar
•
Tighten the new blades. Make sure they are tout enough before blocking them
•
Use the teflon adhesive tape to cover the sealing blades
•
Place the sealing bar into its seat.

7.4. Replacement of the cover gasket

When the cover gasket (17) is worn out, replace it (figure 7.4. page 53).
This will improve the efficiency of the machine and increase its speed rate. Replacement is very easy. After having
removed the gasket which has worn out, clean its seat and insert the new gasket in a linear way. Make sure its ends are
joined. Leave no opening which might prevent the product from being properly vacuum-packed.

7.5. Cleaning machine

Use a normal wet cloth to clean the plexiglas cover (18) (figure 7.5. page 53).
Never use detergents or solvents which might damage the hood and reduce its transparency as well as its resistance.
Use normal detergents for stainless steel to clean the case and the internal tank.
