2. SQUEEGEE ASSEMBLY
The steering geometry and the design of the
squeegee assembly allows the squeegee assembly
to follow the track of the scrub head even in hard
turns. Turns are not pushed sideways around a
pivot point but turn in an arc. This feature eliminates
the need to use side squeegees. The assembly
rides on the floor supported by two wheels that
follow changing levels in the floor. Down pressure
and squeegee flair is constant in relation to the floor.
Spring tension is applied to the squeegee to
maintain good contact with the floor
NOTE: Refer to ADJUSTING SQUEEGEE below.
Rollers are mounted on each end of the squeegee
assembly to assist in rolling by obstacles. The
squeegee assembly is easily removed from lift
mechanism for service and transport.
SQUEEGEE ADJUSTMENT
Adjusting the squeegee is a two-part process. First,
the squeegee tool must have correct pitch in order
for the squeegee blade to have the same deflection
at each tip as well as at the center. The pitch
adjustment is facilitated by the use of a spirit level
mounted on the squeegee tool. The second
adjustment is the amount of deflection or “bend” in
the rear blade. This deflection is controlled by the
height of the tool from the floor. That height is
varied by the wheel adjustment.
TO ADJUST SQUEEGEE PITCH
1.
Choose a smooth, level surface. Turn on the key
switch, release the machine parking brake,
lower the squeegee and drive forward at least 2
feet (60 cm).
2.
With the squeegee down, stop the machine and
set the parking brake. Do not allow the machine
to roll back.
FOR SAFETY: Before leaving or servicing
machine; stop on level surface, turn off machine
and remove key.
3.
Determine the differences, if any, in deflection of
the squeegee blade between each end and the
middle. Proper adjustment is obtained when
deflection is equal all the way across tool. This
should correspond to the bubble being in the
middle position of the spirit level.
4.
To decrease the deflection of the squeegee
blade at the ends, turn knob on squeegee
trailing arm clockwise. To increase the deflection
at the ends of the squeegee assembly, turn
knob counter clockwise.
5.
Again check the deflection of the squeegee
blades. Repeat steps 1 through 4 until the
deflection is equal across the entire rear
squeegee blade.
TO ADJUST SQUEEGEE DEFLECTION
1.
Choose a smooth, level surface. Lower the
squeegee and drive forward at least 2 feet.
2.
With the squeegee down, stop the machine and
set the parking brake. Do not allow the machine
to roll back.
FOR SAFETY: Before leaving or servicing
machine; stop on level surface, turn off machine
and remove key.
3.
Observe the amount of squeegee deflection. It
should deflect 3/8in (9.5 mm) across the entire
width of the squeegee.
4.
To adjust the squeegee defection, loosen knob
on the squeegee slide bar.
5.
Sliding bar to the left increases deflection.
Sliding bar to the right decreases deflection.
6.
Tighten knob on squeegee slide bar.
7.
Turn on the key switch and release the parking
brake. Raise and then lower squeegee
assembly. Drive forward at least 2 feet (60 cm).
8.
Repeat steps 2 through 7 until deflection of 3/8
in. (9.5 cm) is reached.
