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
•
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 dealer or by a qualified electrician.
The BHS 5120 may be used with three 12 volt, 185 amp hour batteries or six 6 volt batteries. The six 6 volt, 244 amp hour batteries will extend the running
time of the machine.
To Install the Batteries...
1
Release the two latches at the back of the machine, tip the
cover shroud forward and lift it off 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 Key Switch (on the right side of the control handle) 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.
