rinse it well with plenty of clean water and dry it thor-
oughly.
7. Insert the new filter screw WM 30905 with the aid of
the Allen key. Lightly tighten the filter screw by turning
to the right.
2. Take a small screwdriver and clean it thoroughly with
washing-up liquid. Then rinse it with plenty of clean
water and dry the screwdriver thoroughly.
The screwdriver must be clean and free from oil and
grease to rule out any risk of explosion.
3. Carefully lift out the sealing ring with the cleaned
screwdriver.
Caution!
Take care not to damage the groove in which the seal-
ing ring is seated.
