Chapter 7. Ordinary maintenance
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.
•
Remove the teflon adhesive tape.
•
Unscrew the screws 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. 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).
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.

7.6. Pump oil replacement

!
Every 3-4 months check the oil level in the pump by removing the front panel. Change the pump oil in case of a change
in colour due to the presence of powders or liquids.
!
Completely change the pump oil every 250 working hours or at least once a year (use the hydraulic oil of the type
specified on the pump).
N.B.: the oil you have replaced must be eliminated according to the procedures established by the
laws in force in the country the equipment has been installed.

and electrical expertise required to work in security conditions.
Proceed as follows:
1. disconnect machine from power mains
2. disassemble components
3. remove oil from the pump
All wastes must be treared, eliminated or recycled according to their classification and to the procedures in force
established by the laws in force in the country the equipment has been installed.
