Installing the Batteries

ENGLISH 9

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.

1Remove 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.

2Turn the Master Key Switch (4) OFF and remove the key.

3Open the Upper (recovery) Tank (1). Remove the battery cables from inside the battery compartment.

4Your 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.

5The 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.

6Carefully 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.

7Coat the terminals and posts with spray-on battery terminal coating (available at most auto parts stores).

8Put one of the black rubber boots over each of the terminals.

FILLING THE SOLUTION TANK

1Either 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.

2Read 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.

3Pour 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.

4Put 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).
