ROUTINE MAINTENANCE

7.4.1 REPLACING THE SEALING BAR COVER TEFLON BAND
After a long period of use, a black mark starts appearing on the sealing bar cover Teflon band, so it must be replaced.
To do so, proceed as follows:
1) Switch the machine off by means of the ON/OFF main switch and disconnect
the plug from the mains socket.
2) Lift the sealing bar by rotating it upwards (A - Fig. 1).
3) Detach the brown Teflon cover (Fig. 2).
4) Wipe the sealing bar with alcohol (Fig. 3).
5) Fit a new band (Fig. 4) cutting the excess length at the two ends (Fig. 5).
CAUTION!
Burning hazard! Do not start Teflon band replacement when the
sealing bars are hot.

CHANGING THE PUMP OIL

WARNING: This operation must be carried out by qualified personnel.
For correct oil change, disconnect the pump from the power supply. The pump must be at normal functioning temperature with the vacuum chamber
at normal atmospheric pressure (no vacuum).
1) Run the pump for about 10 minutes so that the oil becomes fluid, by activating the (PUMP) function.
2) Stop the pump by pressing SEAL.
3) Switch off the machine using the ON/OFF main switch and remove the plug from the power socket.
4) Unscrew the oil filling screw as follows:
5) Remove the stainless steel side (A), then unscrew screw (B) using an Allen key;
6) Get hold of a suitable container for collecting the displaced oil approximately 0.3 liters (SV-31) and 1.2 liters (SV-41) and unscrew the drainage
plug (C) located on the lower section of the pump. Allow the oil to drain out for approximately 10 minutes.
7) Refit the oil drainage plug (C) and top up with oil type ORV 40 for (SV-31) or ORV 60 for (SV-41) until it reaches a level which just exceeds
the halfway point on the pump inspection glass (D).
