SCRUB HEAD FLOOR SKIRTS
The skirts are located in front and rear of the
scrub head. Check these skirts for wear and
damage every 50 hours of operation.
The skirts should clear the floor by 0 to 6 mm
(0 to 0.25 in) when the scrub head is down. Check
the floor skirt adjustment every 50 hours of
operation.
The rear scrub head floor skirts can be adjusted
by pulling the skirt up or down without loosening
the retainer hardware.
The front scrub head floor skirts need the retainer
hardware loosened to move the skirt up or down.
Tighten the retainer hardware enough to hold the
skirt firmly in place.
SCRUB HEAD GAS SPRING
Check the scrub head gas spring for wear and
proper operation every 500 hours of operation.
SCRUB HEAD ADJUSTMENTS
The scrub head is factory adjusted, and the
measurements should not be changed unless
scrub head parts are damaged or are replaced.
SCRUB BRUSHES
Check the scrub brushes daily for wire or string
tangled around the brush or brush drive hub. Also
check the brushes for any damage and wear.
The scrub brushes should be replaced if large
amounts of bristles are missing, or if the
remaining bristles’ length is less than 6 mm
(0.25 in).
NOTE: Be sure to replace brushes in sets.
Otherwise one brush will be more aggressive than
the other.
Cleaning pads must be placed on pad drives
before they are ready to use. The cleaning pad is
held in place by a pad holder.
Cleaning pads need to be cleaned immediately
after using with soap and water. Do not wash the
pads with a pressure washer. Hang dry pads, or
lie flat to dry.
