SQUEEGEE SYSTEM
SQUEEGEE ADJUSTMENT
A squeegee needs to be adjusted to the type of surface that it is operating on. This means
the adjustments that pick up well on rough concrete will probably not work well on glass-
smooth vinyl tile or ceramic tile. The reverse would hold true also, a squeegee set up for a
smooth surface will not work well on rough surfaces. As a squeegee wears, the dynamics
or condition of the blades change, sometimes requiring small adjustments or sometimes
requiring a blade turning or change.
Our squeegee system has only one operator-serviceable adjustment. That adjustment
is the thumb wheel directly in front of the squeegee blade. By turning this knob you pivot
the squeegee back and forth increasing or decreasing the amount of air allowed into the
squeegee under the bottom of the front blade. The basic adjustment you are trying to
achieve is to have the squeegee PERFECTLY parallel with the floor. From that point, rock-
ing the squeegee forward about one half degree of pitch will reduce air leak. Rocking the
squeegee backwards about one half degree will increase the air leak.
PITCH ADJUSTMENT KNOB
The triangular shaped plate that the squeegee bolts to is adjustable for a slight amount of
up/down pitch. As you turn the knob the pitch of the squeegee changes.
Turning the knob clockwise lowers the front blade of the squeegee thereby closing off the
air holes against the floor. This increases suction on the floor. If you adjust it too far for-
ward you can cause chattering problems or excessive front squeegee blade wear.
If too much suction is created the squeegee will “chatter”, and may come off the machine.
If this happens the suction must be reduced by turning the knob counterclockwise 1 to 2
turns to create more of an air leak at the front blade.
You can over adjust in either direction. The squeegee will not work if the back blade is not
evenly deflected across rear, and if wheels do not touch the floor.
