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, 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 Nilfisk-Advance, 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 Turn the Master Key Switch (4) OFF and remove the key.
3 Open the Upper (recovery) Tank (1). Remove the battery
cables from inside the battery compartment.
4 Your machine comes from the factory with enough battery cables
to install six 6 volt batteries. Carefully lift the batteries into the
battery compartment and arrange them exactly as shown.
Secure the batteries as close to the back of the machine as
possible.
5 The terminals on the battery cables are marked “+” for positive
and “–” for negative. Install the battery cables as shown, with the
terminals marked “+” on the positive battery terminals and the
terminals marked “–” 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 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 spray-on battery terminal
coating (available at most auto parts stores).
8 Put one of the black rubber boots over each of the terminals.
FILLING THE SOLUTION TANK
1 Either remove the Solution Fill Cap (22) or the Recovery Tank
Dome Lid (2). NOTE: When filling the solution tank via the top of
the Upper Tank (1), make sure that you pour the solution into the
opening closest to the front of the machine.
2 Read the dilution instructions on the chemical container. Then
figure the proper amount of chemical to mix with 40 gallons
(151.41 liters) of water. For best results, use the Nilfisk-Advance
CarpeTeam™ Extraction Cleaner chemical specially formulated
for use with Nilfisk-Advance carpet extractors.
3 Pour the chemical into the solution tank and fill the tank with warm
water. NOTE: Watch the Solution Level Indicator (21) as you fill
the tank. When it reaches the 40 gallon mark, stop.
4 Put the Solution Filler Cap (22) or the Recovery Tank Dome Lid
(2) back on the machine. NOTE: Make sure the Dome Lid is
properly seated on the tank.
CAUTION!
Use low-sudsing, liquid detergents designed for carpet
extraction.
BEFORE USING THE AQUAMAX™ / AX 650
Thoroughly vacuum the carpet to be cleaned before using the
AquaMAX™ / AX 650 automatic extractor.
PRE-SPRAYING THE CARPET
Pre-spray spots and heavy traffic areas before extracting. Use a hand-
held bottle sprayer or a pressurized “Hudson” type sprayer. Mix the
pre-spray according to the chemical manufacturer’s directions.
PLAN FOR CLEANING
Before you begin extracting, look at the area to be cleaned and plan
your work. Divide the space into sections. Overlap each pass 2 inches
(5 cm).
