B - INSTALLING THE BATTERIES
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 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 dam-
aged if the batteries are not installed and connected properly.
Batteries should be installed by Nilfisk, a qualified electrician, or
the battery manufacturer.
1 Remove the batteries from their shipping crate and carefully inspect
them for cracks or other damage. If damage is evident, contact the
carrier that delivered them or the battery manufacturer to file a damage
claim.
2 Disconnect the Battery Connector / Charger Plug (17).
3 Remove the battery cables from inside the tank. Tip the Solution /
Recovery Tank Cover (11) back until the prop rod catches and then tip
the Recovery Tank (9) forward.
4 Your machine comes from the factory with enough battery cables to
install two 12 volt, 105 amp hour batteries. Carefully lift the batteries
into the battery compartment and arrange them exactly as shown on
page 3 (Figure B).
5 Install the battery terminal covers provided with the machine as shown.
6 Install the battery cables as shown, make sure that the red cable from
the charger plug is connected to the positive terminal and the black
cable connected to the negative terminal. Position the cables so the
battery caps can be easily removed for battery service.
7 Carefully tighten the wing nut on each battery terminal until the terminal
will not turn on the battery post. Do not over-tighten the terminals, or
they will be very difficult to remove for future service.
8 Coat the terminals and posts with grease, petroleum jelly, or spray-on
battery terminal coating (available at most auto parts stores).
9 Connect the Battery Connector / Charger Plug (17).
LOW VOLTAGE CUTOUT SELECTION
Later models of the BA 430 are equipped with a low voltage cutout feature to
prevent over-discharging the batteries. Standard wet cell batteries (flooded
electrolyte) allow for the greatest amount of machine run time due to lower
cutout voltage. If maintenance free batteries (gelled electrolyte) are used, the
low voltage cutout can be set to prevent the over-discharge of the batteries.
The low voltage cutout has two settings, set the first white switch to STD or
position (23) for standard batteries and MF or position (24) for maintenance
free batteries. The selector switch is on the circuit board, which is located
behind the control panel.
