HOUSING ASSEMBLING
Take the bottom panel (ref. 21), the side panels (ref.
22) and place them taking care that slot for the plastic
bearing is downward.
Before fixing the bottom and the side panels make
sure that these pieces are in the right position as in the
picture (place the edge of the bottom panel outside
the side panel).
Join bottom panel with side panels and fix qty. 3 pop
rivets (ref. 2) for each edge by using riveting machine
(ref. 1/Assembling tools). To make the mounting of
the Venturi (ref. 4) easy take care to fix the signed
pop rivet after the Venturi assembling (see arrow in the
previous picture).
Insert Venturi into the housing on the right side as in
the picture. Fix Venturi to bottom panel and then to
side panels with qty. 3 pop rivets for side. Fix the last
pop rivets of the previous step. Qty. 1 pop rivet for
each edge.
Place the top panel (ref. 3) as in the picture (place the
edge of the bottom panel outside the side panel).
