FILTER SHAKER SWITCH
The filter shaker switch, for machines before
serial number 004369, operates the dust filter
shaker motor. The shaker motor shakes the dust
out of the dust filter. To shake the filter, press the
switch for 15 seconds. Release the switch to stop
the filter shaker.
FILTER SHAKER BY-PASS SWITCH
The filter shaker by-pass switch
, for
machines serial number 004369 and above,
controls the automatic filter shaker. When the
switch is in the “on” position, the filter shaker
motor will shake the dust from the filter for 20
seconds when the machine is turned off. When
the switch is in the “off” position, the filter shaker
motor will not shake the dust from the filter when
the machine is turned off. The switch should be in
the “off” position when servicing the machine or
when using the scrubber attachment.
BATTERY CONDITION GAUGE
The battery condition gauge is an option on
machines below serial number 006823. It
indicates the present state of charge of the
batteries. The display should be on the F mark of
the gauge when the batteries are fully charged.
As the batteries discharge, the display will move
down near the E mark and flash. The batteries
should be recharged when the display gets to the
1/4 mark.
VOLTMETER
The voltmeter indicates the present state of
charge of the batteries. The needle should be in
the white zone when the batteries are fully
charged. As the batteries discharge, the needle
will move into the green zone. The batteries
should be recharged when the needle consistently
stays in the red zone.
NOTE: Do not charge the batteries more often
than is necessary. This will prolong the life of the
batteries. Do not allow the batteries to become
fully discharged as this will also damage the
batteries. See BATTERIES in the
MAINTENANCE section.
