Side Skirt Replacement and Adjustment
During normal use the side skirt blades will wear in time. The operator will notice a small amount of water
leaking out underneath the side skirts. You can easily adjust the side skirt height to lower the blades to
allow the squeegee to pick up the water more effectively.
To reverse or replace the scrub system side skirt blade(s):
1. Loosen the two side skirt
Retainer
Knobs
(two per side) and remove
the
Side Skirt Assemblies
from the
scrub deck. Remove the
Side Skirt
Assemblies
by first sliding them
forward, then pulling them off.
2. Remove all the hardware that
holds the
Skirt Blades
to the
Skirt
Weldments
. Note that the
Skirt
Blade
is held on with tool-less
retainers. Simply loosen the large
Thumb Nuts
, then turn the
Knobs
on the outside of the
Skirt Strap
until they are horizontal, then
push them through the slots. The
small
Inside Blade
is held on by
two screws and nuts and has two
working edges.
3. The main
Skirt Blade
has four
working edges as shown. Turn the
Skirt Blade
so a clean, undamaged
edge faces toward the center of
the machine. Replace the
Skirt
Blades
as a set if all four edges are
nicked, torn or worn beyond their
ability to be adjusted.
4. Reinstall the
Side Skirt Assemblies
onto the machine and check the
height of the
Skirt Blades
for
correct contact on the floor when
the brush deck is lowered to the
scrub position. The
Skirt Blades
should fold over just enough when
scrubbing that all the waste water
is contained inside the skirting. If
necessary, adjust the height of the
Side Skirt Assemblies
as follows:
a. Loosen the
Retainer Knobs
.
b. Rotate the
Height Adjusting
Knobs
to raise or lower
the
Side Skirt Assembly
as
necessary.
Note:
Make small adjustments to obtain good blade wiping. Do not lower the blades too much to
where they fold over excessively as this can cause excessive blade wear.
c. When the
Skirt Blade
contact is correct, tighten the
Retainer Knobs
.
