SQUEEGEE SYSTEM
REPLACING BLADES
We stock individual blades or blade kits that include a blade set and new set of squeegee
wheels. We recommend changing wheels when you change blades as they are wear items
and they are critical to the proper operation of the squeegee.
When installing blades they must be put on without bumps or ripples. The squeegee
should have a smooth edge that rides on the floor. When adjusting the blades you need to
achieve a uniform “fanning” of the blade from one tip to the other. If the blade does not do
this it is installed incorrectly or misadjusted.
When changing or turning squeegee blades it is very important to note the orientation of the
stainless steel retaining band for re-installation. The holes are offset to make a wide side
and narrow side. The wide side always goes UP. If the band is installed incorrectly the
squeegee will not function properly
ORDERING BLADES
1. Find the squeegee size:
Check the stamped number on the top of the squeegee body and order blades the
corresponding blade size: (32, 35 or 38 inches).
2. Choose the appropriate material:
Gum rubber - These blades are tan in color and best for most applications including
irregular floors. They wear out quickly on rough floors however and do not tolerate
oil, other petroleum products or heavy citrus cleaners. The kit number suffix for gum
rubber is “G”. (Example 28-770-G)
Linatex - These blades are red in color and designed to be very durable while at the
same time giving optimum performance. They are very abrasion resistant and perform
acceptably on irregular floors. They tolerate oil, petroleum products and heavy citrus
cleaners better than gum rubber. The kit number suffix for Linatex is “L”.
Polyurethane - These blades are nearly clear and are recommended for oil, petroleum
or heavy citrus cleaner applications where Gum or Linatex would fail. It rarely works as
efficiently as Gum or Linatex but is somewhat abrasion resistant. The kit number suffix
for polyurethane is “U”.

The front blade wears very well when properly adjusted, but it can get torn. It can be
installed one of two ways: “3 notches down” for normal floors, and “5 notches down” for
extremely smooth floors.
