If a lift is not available use the following instructions:
1. Locate the six plastic fasteners 600965 holding the front flap in place. These fasteners are
removed by first pulling out their center pin.
The right three plastic fasteners can be accessed from the right scrub brush opening and the left
three fasteners can be accessed from the rear scrub brush opening.
2. Remove the six plastic fasteners along with the front skirt and retaining bar 730983.
3. Position the far right holes of the new front skirt and retaining bar 730983 over the far right hole
in the scrub head. Insert a new plastic fastener 600965 through the retainer, the skirt, and into
the hole in the scrub head. Using a small hammer tap the center pin flush with the head of the
fastener.
4. With the machine on the floor it is not possible, due to the proximity of the drive motor housing,
to press in the center pin of the far left plastic fastener. A 1/4-20 x 3/4 long stainless steel bolt
and lock nut can be used in place of this plastic fastener. Install this bolt through the retainer
bar, the skirt, and the far left frame hole. Install the nut.
5. Install the remaining plastic fasteners.
Installing the new side skirt:
The installation of the side skirt requires drilling four holes into the left side plate of the scrub head.
The 730325 HOLE TEMPLATE drawing shows the location and size of the four required holes.
1. Locate the lower snap ring 600569 on the left side squeegee mount hinge pin 730642.
2. Remove the lower snap ring 600569 and raise the hinge pin 730642 to provide access for
marking and drilling the front two skirt mounting holes.
3. Mark and drill the four side skirt mounting holes per the side skirt hole location drawing. The
scrub head is stainless steel so it is recommended that you used a center punch and predrill
using a small diameter drill bit.
Note when installing the side skirt: The front half (tall end) of the side skirt is positioned against the inner
face of the scrub head left side plate. The rear half of the side skirt is placed against the outer face of the
scrub head left side plate.
4. Insert two plastic fasteners 600965 through the two holes in the front (short) skirt retainer bar
731364 and through the back side of the side skirt (see scrub head lift group 730113 parts
manual pages).
5. Insert the two fasteners through from the inner side of the scrub head side plate (so that the
points of the plastic fasteners are pointing outwards). Using a small hammer tap the center pins
flush with the head of the fastener.
