Fig. 6/3: Replacing the cover gasket
There must be no melt at all left in the tank when the cover gasket is replaced. Therefore
discharge the melt completely, e.g. into a collecting vessel.
1. Let the device heat up.
Continue activating the trigger until the tank is completely empty.
2. Disconnect the compressed air supply.
3. Disassemble the entire closure unit (see Chapter 6.7).
4. Release the fastening screws (D1) of the sealing plate (D2) with the Phillips screwdri-
ver. Carefully remove the sealing plate.
5. Carefully remove the gasket (D5) from the pressure plate (D6).
6. Set the new gasket in the pressure plate in such a way that it fits evenly all over.
7. Mount the sealing plate. Observe the position of the washer (D3) and the O-ring (D4) of
the ventilation opening. Tighten the fastening screws (D1) alternately.
