Squeegee blade check and replacement
1. Clean the squeegee as shown in the previous paragraph.
2. Check the condition of the front (A, Figure 3) and rear (C) blades, ensuring there are no cuts and tears; if
necessary, replace them as shown below. Check that the front corner (F) of the rear blade is not worn; otherwise,
turn the blade to replace the worn corner with one of the three remaining intact corners. If the other corners are
worn too, replace the blade according to the following procedure:
Use the tab (G) to release and remove the elastic strap (D) from the fasteners (H), then turn or replace the rear
blade (C).
Install the rear blade in the reverse order of removal. Fasten the elastic strap (D) to the fasteners (H) starting
from one side. To make the fastening procedure easier, secure the fasteners one at a time, by locking the strap
before the fastener with one hand and pulling it with the other hand.
Remove the fastening strap (B) by disengaging it from the fasteners (J).
Replace (or overturn) the front blade (A), then reinstall the fastening strap (B).
3. Install the squeegee (E, Figure 2) and fasten the knob (D, Figure 2).
4. Connect the vacuum hose (B, Figure 2) to the squeegee connector (C, Figure 2).
