Loosen the (2) set screws and remove Pulley (I) from potentiometer shaft (the belt is normally loose enough to allow removal of the pulley). 3 Remove the plastic cover from the speed control. 4 Carefully pull Connector (H) off the speed control (pull toward back of machine). 5 Connect an ohmmeter (on 0 x 100 scale) to the green and yellow wires on the connector. 6 Turn the potentiometer shaft until the meter reads between 2400 and 2600 ohms. 7 Without turning the potentiometer shaft, install pulley (I) and tighten the set screws. 8 Test the drive system for proper operation before installing speed control cover and handle cover panel.

ELECTRICAL SYSTEM INSTALL THE BATTERIES
WARNING! Use extreme caution when working with batteries. Sulfuric acid in batteries can cause severe injury if allowed to contact 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. Wear chemical goggles, rubber gloves and a protective apron. Do not smoke. Do not allow tools to touch more than one battery terminal at a time. Work in a well-ventilated area.
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 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 carrier that delivered them or the battery manufacturer to file a damage claim. Turn the Master Key Switch (11) OFF and remove the key. Remove the battery cables from inside the tank. Tip the solution tank forward, to the locked position and lift the recovery tank off the machine. Your machine comes from the factory with enough battery cables to install four 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. 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. 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. Coat the terminals and posts with grease, petroleum jelly, or spray-on battery terminal coating (available at most auto parts stores). Put one of the black rubber boots over each of the terminals.

ELECTRICAL SYSTEM CHARGING THE BATTERIES Charge the batteries each time the machine is used, or whenever the Battery Meter (3) indicator is in the RED area.
WARNING! Do not fill the batteries before charging. Charge batteries in a well-ventilated area. Do not smoke while servicing the batteries. To charge the batteries… 1 Open the access door on the left side of the machine. Push the connector from the charger into the Battery Charger Connector (17) of the machine. 2 Follow the instructions on the battery charger. 3 Check the fluid level in all battery cells after charging the batteries. Add distilled water, if necessary, to bring the fluid level up to the bottom of the filler tubes.
CAUTION! To avoid damage to floor surfaces always wipe water and acid from the top of the batteries after charging.
BATTERY MAINTENANCE Proper maintenance of electric vehicle batteries can greatly extend their life. Well-maintained batteries may last up to 3 years, but failure after 1 year is common if maintenance has been poor. There are 3 simple rules for good battery maintenance: • Maintain Proper Electrolyte Level (weekly) - Use distilled water in batteries whenever possible. If batteries are discharged, add just enough water to cover the plates in each cell. If batteries are fully charged, fill each cell to the bottom of the filler tube. Do not over-fill the batteries! Do not add acid to batteries! • Keep the Batteries Charged (weekly) - Batteries should be charged each time that a machine is used for more than 1 hour. Machine operators should tip the tanks to the side of the machine for charging, to avoid a concentrated build-up of hydrogen gas. Operators should follow the instructions provided with their specific battery charger, to determine how long the batteries should be charged. Even when a machine is stored, the batteries should be charged once a month to prevent the batteries from “sulfating”. Almost all battery caps are vented, so there’s no need to loosen or remove them for charging. • Keep the Batteries Clean (monthly) - Use a damp cloth to wipe dirt from the top of the batteries. Battery terminals must be clean and tight. If the tops of the batteries are wet after charging, the batteries have probably been over-filled or over-charged. Note: If there is acid on the batteries, wash the tops of the batteries with a solution of baking soda and water (2) tablespoons of baking soda to 1 quart of water.
BATTERY TESTING A battery problem is usually recognized by the machine operator, as a decrease in the machine’s running time. This condition is usually caused by one (or more) “dead cell” in the battery system- that is, one (or more) cell that is putting out less voltage than the other cells. Note: Always charge batteries before testing. There are 2 ways to find a dead cell: • Use a hydrometer to check the specific gravity (or “state of charge”) of the fluid in each cell. A dead cell is one that reads 50 points (or more) lower than the other cells. • Use a volt meter to check the voltage of each battery with the brush and vac motors running. The battery with the dead cell will read 1 or 2 volts lower than the other batteries in the system. If the batteries in the machine are more than 1 year old, it’s usually best to replace the whole set, rather than replacing just one battery.
