LOW VOLTAGE CUTOUT SELECTION
The SELECTSCRUB 17 is equipped with a low voltage cutout feature to
prevent over-discharging the batteries. Standard wet cell batteries (flooded
electrolyte) allow for the greatest amount of machine run time due to lower
cutout voltage. If maintenance free batteries (gelled electrolyte) are used, the
low voltage cutout can be set to prevent the over-discharge of the batteries.
The low voltage cutout has two settings, set the first white switch to STD or
position (23) for standard batteries and MF or position (24) for maintenance
free batteries. The selector switch is on the circuit board, which is located
behind the control panel.

D - BATTERY CONDITION INDICATOR OPERATION
To operate, the Brush Switch (13) or the Vac Switch (14) must be turned on to
activate the Battery Condition Indicator (19) to determine the charge condition
of the battery pack.
Listed below is the explanation of the Battery Condition Indicator (19) light
functions:
1Flashing Red Light: Condition of battery 95% to 99% discharged.
2Constant Red Light: 100% discharged.*
*NOTE: When the indicator glows steady RED, the operator will have 2
minutes of run time left (for batteries in good condition). The brush motor will
automatically shut off and the vac motor will continue to run for 10 minutes to
pick up any solution left on the floor.
Additional Note: If at any time during machine operation the battery system
voltage drops below 19 volts, the brush and vac motors will immediately shut
off. The red light will also glow steady to indicate a low voltage fault condition.
Check condition of batteries and recharge them.
If an overload occurs, determine and correct the cause of the overload. The
machine has an internal electronic circuit breaker built into the control board.
To reset the electronic circuit breaker, turn the switch for the affected device
off and then back on.
