SQUEEGEE SYSTEM
SQUEEGEE BLADES
Squeegee blades are wear items. The back blade wears fastest on the edge that contacts
the floor (lower front edge). This blade can ideally be turned four times. It is important to
have a sharp squeegee edge on the floor; otherwise the squeegee does not scrape the
water off the floor but instead glides right over it.
TRIANGLE PLATE & TOW BAR
These parts cannot be bent at all. They must be completely straight and flat. If either is
bent replace it.
If you replace the triangle plate, adjust the clearance between the bottom of the plate and
the top of the tow bar so clearance is 7/8” (22 mm). Squeegee will not work properly if this
adjustment is off!
UP/DOWN MOVEMENT
The squeegee must be able to travel up and down freely so it can glide over bumps and
uneven floors. It is hinged at the front as shown.
If the squeegee suspension does not move up and down properly check the bolts and the
Oilite bushings at the pivot point. If the bolts are too tight (may have been tightened by
customer by mistake) or the bushings are dried out or worn the squeegee will not be able
to float properly.
SIDEWAYS MOVEMENT
The squeegee must be allowed to move from side to side so that if it hits an obstacle it can
move out of the way. If squeegee does not move freely from side to side check the bolt
tension on the two pivot bolts. Check that the white plastic washers between the pivot
plate and the trailing arm to make sure they are not damaged.
In order for the squeegee system to operate properly the parts have to be assembled
properly. The space between the bottom of the “Squeegee triangle plate” – E, and the
“squeegee trail arm” – C, must be exactly 7/8” on all models but the 390, the 390 mea-
surement is 1 3/8”.
If this dimension is incorrect you will never get the squeegee blade
adjusted properly. If you believe you are having problems with this adjustment, please call
the factory @ 800-634-4060.
