SQUEEGEE BLADE CHECK AND REPLACEMENT
1. Clean the steel or the aluminum squeegee, as shown in the
previous paragraph.
2. Check that the edges (E, Figure 23) of the front blade (C) and
the edges (F) of the rear blade (D) lay down on the same level,
along with their length; if necessary adjust their height
according to the following procedure:
x Remove the tie rod (G), disengage the fasteners (M) and
adjust the rear blade (D), then engage the fasteners (M) and
install the tie rod (G).
x Loosen the knobs (I) and adjust the front blade (C), then
tighten the knobs.
3. Check the front blade (C) and rear blade (D) for wear, cuts
and tears; if necessary replace them according to the
following procedure. Check that the front corner (J) of the
rear blade (D) is not worn; if necessary overturn the blade to
replace the worn corner with an integral one. If the other
corners are worn too, replace the blade according to the
following procedure:
x Remove the tie rod (G), disengage the fastener (M) and
remove the retaining strip (K), then replace/overturn the rear
blade (D). Assemble the blade in the reverse order of
disassembly.
x Unscrew the knobs (I) and remove the retaining strip (L), then
replace front blade (C). Assemble the blade in the reserve
order of disassembly. After the blade replacement (or
overturning), adjust the height as shown in the previous step.
