Replacement of coarse filters GF2 and GF3
1. Detach the coarse filter (pos. 1) together with the
angular hose fittings (pos. 2) from the upper and
lower connection piece.
2. Detach both angular hose fittings from the coarse
filter by twisting gently and attach them to the new
coarse filter.
3. Attach the new coarse filter with angular hose
fittings to the connection pieces (installation
position as indicated on BEA 060).
i
Affix the sticker 1 689 980 296 to each new coarse
