B. Polish Width
If the polish mark width is too wide, turn the main
brush lift handle clockwise to raise the brush.
If the polish mark width is too narrow, turn the
main brush lift handle counterclockwise to lower
the brush.
If any adjustments are made, recheck the main
brush pattern before resuming work with the
machine.
SIDE BRUSH
The side brush sweeps debris from walls or curbs
into the path of the main brush. It should be
inspected daily for wear or damage. Remove any
string or wire found tangled on the side brush or
side brush drive hub.
The side brush should be replaced when the
remaining brush bristle measures 1 in (25 mm) in
length.
The side brush adjustment should be checked
after every 20 hours of operation. The side brush
is properly adjusted when, with the side brush arm
in the “raised” position, there is approximately
1 in (25 mm) of space between the floor and the
side brush bristles.
Side brush adjustments are made by mounting
the side brush in a different one of the five
mounting holes in the side brush drive shaft.
