ELECTRIC MOTORS
The carbon brushes on the vacuum fan motor(s)
should be inspected after every 500 hours of
machine operation. The carbon brushes on the
scrub brush motors and propelling motor should
be inspected after every 1000 hours of machine
operation.
SCRUB BRUSHES AND PADS
The machine can be equipped with either
disk
or
cylindrical
scrub brushes, or cleaning pads. Check
scrub brushes daily for wire or string tangled
around the brush or brush drive hub. Also check
for brush damage and wear.
DISK BRUSHES
Replace the brushes when they no longer clean
effectively.
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 pads, or lie
pads flat to dry.
NOTE: Be sure to replace brushes and pads in
sets. Otherwise one brush or pad will be more
aggressive than the other.
