Figure B.
B
2Make sure the key switch is in the OFF position.
3Install the battery cables as shown in figure B, with the terminals marked
“P” on the positive battery posts and the terminals marked “N” on the
negative battery posts. Position the cables so that the caps can be
easily removed when it is necessary to add water to the batteries.
4Tighten the nut on each battery terminal just enough to keep the terminal
from being turned on the battery post. Then tighten the nut one more
full turn.
5Coat all the terminals and posts with grease, petroleum jelly or spray-on
battery coating (available at most auto parts stores).
6Put on the black rubber “boots” over each of the terminals and use the
plastic tie straps to hold them in place.
7Join the connector from the battery pack to the connector on the control
panel.
8Reassemble machine.
NOTE: Charge the batteries before using the machine.

4 Remove the old pad and install a new one, being careful to center it on
the outside diameter of the pad driver. NOTE: Vibration could occur if you
center the hole in the pad to the opening for the pad retainer. Always
use a high quality pad rated to operate at 2000 rpm.
