1 Remove the batteries from their shipping crate and carefully inspect
them for cracks or other damage. If damage is evident, contact the carrier that delivered them or the battery manufacturer to file a damage claim.
2 Disconnect the Battery Connector / Charger Plug (17). 3 Remove the battery cables from inside the tank. Tip the Solution /
Recovery Tank Cover (11) back until the prop rod catches and then tip the Recovery Tank (9) forward.
4 Your machine comes from the factory with enough battery cables to
install two 12 volt, 105 amp hour batteries. Carefully lift the batteries into the battery compartment and arrange them exactly as shown on page 3 (Figure B).
5 Install the battery terminal covers provided with the machine as shown. 6 Install the battery cables as shown, make sure that the red cable from
the charger plug is connected to the positive terminal and the black cable connected to the negative terminal. Position the cables so the battery caps can be easily removed for battery service.
7 Carefully tighten the wing nut on each battery terminal until the terminal
will not turn on the battery post. Do not over-tighten the terminals, or they will be very difficult to remove for future service.
8 Coat the terminals and posts with grease, petroleum jelly, or spray-on
battery terminal coating (available at most auto parts stores).
9 Connect the Battery Connector / Charger Plug (17).
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:
1 Flashing Red Light: Condition of battery 95% to 99% discharged. 2 Constant 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.
