15. Reattach the squeegee lift linkage.

the Impeller on, drive the machine forward
approximately two feet (.61 meters) and set foot
brake. Examine the flare in the squeegee rubber to
see that it is uniform around the entire parabola. If
not, go through Steps 4-17

Turning or Replacing the Rear Squeegee Blade
The rear blade on the main squeegee frame has four
different edges that may be used: the front and back lower
edge and the front and back upper edge. When the edge
in use becomes worn to the midpoint of thickness, turn the
rubber to an unused edge in the order indicated:
1. Front Lower Edge,
2. Opposite Lower Edge,
3. Front upper Edge and
4. Opposite Upper Edge.
Removal and replacement instructions follow. This
procedure can be performed with the squeegee tool on or
off the machine.
NOTE: Removal and replacement of the inner squeegee
rubber is easier if the squeegee frame is
removed from the machine.
1. Unlatch the clamping strap at the center of the
squeegee frame and remove the 2 outer knobs.
2. Remove the metal strap, the two back-up strips and
the outer squeegee blade.
3. Turn the side ends of the squeegee blade 180°, or
turn the rubber upside down to expose an unused
edge. Reposition the blade on the pins of the
squeegee frame.
4. Reposition the first back-up strip using the top
holes.
5. Reposition the second back-up strip using the
bottom holes.
6. Reposition the metal strap and reattach the two
outer knobs.
7. Reattach the straps at the center being careful not
to bunch the blade.
NOTE: Replace the back-up strips only if they
lose their elasticity.
