PREPARING THE MACHINE
FOR USE
(B)-INSTALLING THE BATTERIES
1 Carefully lift the batteries into the battery tray. Arrange as shown
in Figure B.

ENGLISH
EN
(C)-PAD INSTALLATION
Your local NilÀ sk distributor can provide the proper pads and Á oor À nishes for
use with this machine.
CAUTION!
Using the wrong kind of pad on this machine can damage the Á oor. 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.
4 Remove the old pad and install a new one, being careful to center it on
the pad driver.
2 Make sure the key switch is in the OFF position.
3 Install the battery cables as shown in À gure 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.
5 Retighten the pad retainer as tight as possible.
6 Raise the back of the machine to lower the pad housing by lifting as
shown.
(D)-DUST BAG INSTALLATION
Your local NilÀ sk distributor can provide the proper pads and Á oor À nishes for
use with this machine.
IMPORTANT!
Install dust collector bag on top of control housing (see Figure
D). The dust collection system will not operate properly if the
collector bag is full or torn.
(E)-ADJUSTING PAD PRESSURE
The pad pressure is set at the factory for optimal burnishing with most
pad and À nish combinations. If unique pad or À nish conditions require
pad pressure adjustments, adjust by following the procedure below.
NOTE: Pad pressure adjustments should be performed by a qualiÀ ed
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.
8 Reassemble machine.
NOTE: Charge the batteries before using the machine.
4 To increase pad pressure, turn bolt (B) counterclockwise.
5 Re-tighten jam nut (A).
