BATTERY DISCHARGE INDICATOR
The battery discharge indicator shows the charge
level of the batteries with a segmented display.
When the batteries are fully charged, all the
segments are lit. As the batteries discharge, the
segments shut off.
The batteries should be recharged when all the
segments have shut off. At this point, the
scrubbing functions will automatically shut off to
alert the operator of the battery condition. The
squeegee and vacuum can be operated, with the
rear squeegee switch, for an additional 30
seconds to pick up any excess water.
NOTE: Do not charge the batteries more often
than is necessary to prolong the life of the
batteries. Do not charge the batteries with a “top
off” charge if there is enough remaining charge in
the batteries for the next machine use. Discharge
the batteries to a 20% level, when the battery
discharge indicator segments shut off, before fully
charging the batteries. Do not allow the batteries
to become completely discharged as this will also
damage the batteries. See BATTERIES in the
MAINTENANCE section.
HOURMETER
The hourmeter records the number of hours the
machine has been operating. This information is
useful when maintaining the machine.
