BATTERY INSTALLATION

____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

WARNING!

Use extreme caution when working with batteries. Sulfuric acid in batteries can cause severe injury if allowed to contact the skin or
eyes. Explosive hydrogen gas is vented from inside the batteries through openings in the battery caps. This gas can be ignited by any
arc, spark or flame.

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 touch more than one battery terminal at a time.

CAUTION!

Electrical components in this machine can be severely damaged if the batteries are not installed and connected properly. Batteries
should be installed by your local Nilfisk-Advance dealer or by a qualified electrician.

Your Whirlamatic comes from the factory with battery cables to connect three 12 volt batteries.
Six 6 volt batteries may be used (instead of the 12 volt batteries) to extend the running time of the machine. 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 can be ordered from your local Nilfisk-Advance Distributor.

To Install the Batteries...
1 Release the two latches (12) at the back of the machine, tip the cover shroud forward and lift it off of the machine. Remove the battery cables from the battery

tray.

2 If you are using three 12 volt batteries, carefully 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 machine.
If you are installing six 6 volt batteries, lift the battery tray out of the machine and turn it around so that the ribbed area faces toward the front of the machine,
as shown in Figure 2. Carefully place the batteries into the battery tray, arranged exactly as shown. Discard the battery retaining strap - it is not required when
six 6 volt batteries are used.

3 Make sure that the Master Switch (6) is in the OFF position.
4 Install the battery cables 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 cables so that the caps can be easily removed when it is necessary to add water to the batteries.

5 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.
Do not over-tighten the nuts, or it will be very difficult to remove the terminals for future service.
6 Coat all of the terminals and posts with grease, petroleum jelly or spray-on battery coating (available at most auto parts stores).
7 Put one of the black rubber “boots” over each of the terminals and use the plastic tie straps to hold them in place.
