Hopper Disassembly/Assembly (Continues)
Assembly
11 Assemble the components in the reverse order of disassembly
12 Check that the hopper operates properly and that it is properly aligned; if necessary align it as shown
below
Alignment Adjustment
• To allow for a proper vacuuming capacity it is necessary that, when the hopper (A) is closed, all the pe-
rimeter of its gasket (J) is sticks to the chassis (K) of the machine. If this condition is not satisfied because
the hopper and machine chassis are misaligned, these must be aligned with the side flange (F), as shown
below
13 The standard assembly of the flange (F) is performed by placing the "V" groove (L) at "6 o'clock", thus
engaging the notch (M) on the tooth (N) of the hopper housing (A)
14 To adjust the hopper alignment:
• Perform steps 2 to 5
• Remove the screw (C) and retrieve the components (D)
• Remove the screw (P) and remove the flange (F) from its housing, then insert it again after turning it
as necessary to restore the alignment (each notch corresponds in negative or positive to 0.5 degrees,
as shown on the flange itself).
• Tighten the screw (P)
• Assemble the components (D), on the flange (F) and tighten the screw (C).
15 Removing the main broom and checking that there is no light passing through the seal and the chassis
16 Check that the hopper operates properly and that it is properly aligned; if necessary repeat the
alignment procedure
