Battery Installation
WARNING !
Use extreme caution when working with batteries. Sulphuric acid in batteries will 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 electrical arc, spark or flame.
When Servicing Batteries...
*
Remove all jewelry
*
Do not smoke
*
Wear safety glasses
*
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 Nilfisk or by a qualified electrician.
1
Remove the batteries from their shipping crate and carefully inspect them for cracks or other damage. If damage is evident contact the
trucking company that delivered them or the battery manufacturer to file a damage claim.
2
Make sure the Master Key Switch (12) is OFF (remove the key).
3
Remove the battery cables from inside the tank. Tip the solution tank to the forward, locked position and tip the recovery tank to the
side of the machine.
4
Your machine comes from the factory with enough battery cables to install four 6 volt, 244 amp hour batteries. Two 12 volt batteries
may be used (instead of the 6 volt batteries) but the running time of the machine will be reduced. Carefully lift the batteries into the battery
compartment and arrange them exactly as shown below.
5
The terminals on the battery cables are marked "P" for positive and "N" for negative. Install the battery cables as shown, with the terminals
marked "P" on the positive battery terminals and the terminals marked "N" on the negative terminals. Position the cables so the battery
caps can be easily removed for battery service.
6
Carefully tighten the nut in each battery terminal until the terminal will not turn on the battery post. Then tighten the nut one additional
full turn. Do not over-tighten the terminals or they will be very difficult to remove for future service.
7
Coat the terminals and posts with grease, petroleum jelly, or spray-on battery terminal coating (available at most auto parts stores).
8
Put one of the black rubber boots over each of the terminals.
