Replacing the scrub head front skirt:
Here you will be replacing the short front skirt 730982 (Rev *) with the new longer front skirt 730982
(Rev A).
1. Remove the front and rear scrub brushes.
The following procedure is more easily performed on a lift. If a lift is not available go to “If a lift is not
available…..”
With the machine on a lift:
1. Locate the six plastic fasteners 600965 holding the front flap in place. These fasteners are
removed by first pulling out their center pin. This can be done by using two screw drivers in the
slots provided on the head of the fastener or the inner pin can be tapped out from the front side
of the scrub head using a small punch and hammer.
Remove the six plastic fasteners along with the front skirt and retaining bar 730983.
2. 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.
3. Install the far left fastener in the same manner.
4. Install the remaining plastic fasteners.
