2 Make sure the key switch is in the OFF position.

3 Install 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.

4 Tighten 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.

5 Coat all the terminals and posts with grease, petroleum jelly or spray-on battery coating (available at most auto parts stores).

6 Put on the black rubber "boots" over each of the terminals and use the plastic tie straps to hold them in place.

7 Join the connector from the battery pack to the connector on the control panel.

8 Reassemble machine.

NOTE: Charge the batteries before using the machine.

(C)-PAD INSTALLATION

Your local Nilfisk distributor can provide the proper pads and floor finishes for use with this machine.

CAUTION!

Using the wrong kind of pad on this machine can damage the floor. The pad must be centered properly on the pad holder to prevent machine vibration.

For pad installation, follow the steps below (see steps 1 - 6 in Figure C):

1 Turn the key switch off.
2 Put the machine in the position shown, to access the pad retainer.
3 Go to the front of the machine. While holding the pad retainer with one hand, rotate the pad and pad driver counter clockwise to loosen the pad retainer.

The pad pressure is set at the factory for optimal burnishing with most pad and finish combinations. If unique pad or finish conditions require pad pressure adjustments, adjust by following the procedure below. NOTE: Pad pressure adjustments should be performed by a qualified service technician.

1 Turn key switch off (O).
2 From underneath burnisher, loosen jam nut (A).
3 To decrease pad pressure, turn bolt (B) clockwise.
4 To increase pad pressure, turn bolt (B) counterclockwise.
5 Re-tighten jam nut (A).
