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.
