WARNING!
Use extreme aution when working with batteries. Sulfuri a id in batteries an ause severe injury if allowed to onta t the skin or
eyes. Explosive hydrogen gas is vented from inside the batteries through openings in the battery aps. This gas an be ignited by any

WHEN SERVICING BATTERIES...
•Remove all jewelry.
•Do not smoke.
•Wear safety glasses, rubber gloves and a rubber apron.
•Work in a well-ventilated area.
•Do not allow tools to tou h more than one battery terminal at a time.
CAUTION!
Ele tri al omponents in this ma hine an be severely damaged if the batteries are not installed and onne ted properly. Batteries
should be installed by your lo al Nilfisk-Advan e dealer or by a qualified ele tri ian.
Your Whirlamati omes from the fa tory with battery ables to onne t three 12 volt batteries.
Six 6 volt batteries may be used (instead of the 12 volt batteries) to extend the running time of the ma hine. To install these batteries, you will need the following
additional parts:
QTY PART NO. DESCRIPTION
3 56363936 BATTERY CABLES
6 56372673 BATTERY BOOTS
6 56478246 TIE STRAPS
These items an be ordered from your lo al Nilfisk-Advan e Distributor.
To Install the Batteries...
1Release the two lat hes (12) at the ba k of the ma hine, tip the over shroud forward and lift it off of the ma hine. Remove the battery ables from the battery
tray.
2If you are using three 12 volt batteries, arefully lift them into the battery tray, arranged as shown in Figure 1. Install the battery retaining strap as shown,
to hold the batteries toward the rear of the ma hine.
If you are installing six 6 volt batteries, lift the battery tray out of the ma hine and turn it around so that the ribbed area fa es toward the front of the ma hine,
as shown in Figure 2. Carefully pla e the batteries into the battery tray, arranged exa tly as shown. Dis ard the battery retaining strap - it is not required when
six 6 volt batteries are used.
3Make sure that the Master Swit h (6) is in the OFF position.
4Install the battery ables as shown in Figure 1 or Figure 2, with the terminals marked “P” on the positive battery posts and the terminals marked “N” on the
negative battery posts. Position the ables so that the aps an be easily removed when it is ne essary to add water to the batteries.
5Tighten the nut on ea h battery terminal just enough to keep the terminal from being turned on the battery post. Then tighten the nut one more full turn.
Do not over-tighten the nuts, or it will be very diffi ult to remove the terminals for future servi e.
6Coat all of the terminals and posts with grease, petroleum jelly or spray-on battery oating (available at most auto parts stores).
7Put one of the bla k rubber “boots” over ea h of the terminals and use the plasti tie straps to hold them in pla e.
