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).
ATTENTION!
Do not start Teflon band replacement with the sealing bars hot, as
there is danger of burns.

For correct oil change, disconnect the pump from the power supply. The pump must be at normal functioning temperature with the vacuum chamber

1) Run the pump for about 10 minutes so that the oil becomes fluid, by activating the Jars function.
2) Stop the pump by pressing STOP.
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 (A) as follows:
• Remove the stainless steel side (B), then unscrew screw (A) using a hex wrench;
5) Use a container to hold the oil drained out and unscrew oil drain screw (C) provided at the bottom of the
pump.
Let the oil flow out into the container for about 10 minutes.
6) Refit the oil drain screw (C) and fill with the type of oil indicated in the "TECHNICAL DATA" table to a level
slightly above half-way on the level indicator on the pump (D).
