2.4 Retrofitting Procedure
2.4.1 Preparing Both Air Filter Boxes
Perform the following jobs in advance so that you do not need to interrupt production more than
necessary. 2
à Pick up the preassembled air filter box (Item no. see Sec. 2.2).
à Press gently against the lug on the long side of the tray (see Fig. 2.5.1) and lift the cover off
the tray of the air filter box.
NOTE:
The self adhesive Velcro strips (L = 194 and 360), Item no. see Sec. 2.2, are already stuck onto
the cover frame.
The uncovered central strut of the frame must be pointing downwards in the installation position.2
à Place the filter mat (Item no. see Sec. 2.2), which is already attached to a filter frame when
delivered, on the cover frame so it is flush with the outside edges of the frame all the way
around.
à Press the filter mat (with frame) against the Velcro strips along the outside edges.
à Also perform the steps described above for the second air filter box which you are going to
retrofit.
