BATTERIES

If your machine shipped with batteries installed do the following:

Check that the batteries are connected to the machine  (15). Turn ON the Key Switch  (A) and check the Battery Indicator (F6 or E). If the gauge is completely ﬁ lled or the green light is ON, the batteries are ready for use. If the gauge is less than full or the green light is OFF, the batteries should be charged before use. See the “Charging The Batteries” section.

IMPORTANT!: IF YOUR MACHINE HAS AN ONBOARD BATTERY CHARGER REFER TO THE OEM PRODUCT MANUAL FOR INSTRUCTIONS REGARDING SETTING THE CHARGER FOR BATTERY TYPE.

If your machine shipped without batteries installed do the following:

Consult your Authorized Advance dealer for recommended batteries. Install the batteries by following the instructions below.

IMPORTANT!: IF YOUR MACHINE HAS AN ONBOARD BATTERY CHARGER REFER TO THE OEM PRODUCT MANUAL FOR INSTRUCTIONS REGARDING SETTING THE CHARGER FOR BATTERY TYPE.

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 ﬂ ame. Do not install any lead-acid battery in a sealed container or enclosure. Hydrogen gas from overcharging must be allowed to escape.

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

• ALWAYS disconnect the negative (ground) cable ﬁ rst when replacing batteries to prevent sparks.

• ALWAYS connect the negative cable last when installing batteries.

CAUTION!

Electrical components in this machine can be severely damaged if the batteries are not installed and connected properly. Advance, a qualiﬁ ed electrician, or the battery manufacturer should install batteries.

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 ﬁ le a damage claim.

2 Turn the Master Key Switch (A) OFF and remove the key. 3 Disconnect the Battery Pack Connector (15) 4 Tip the recovery tank to the side, locked position. Remove the battery cables from inside

the battery compartment.

5 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 in FIGURE 1. Secure the batteries as close to the back of the machine as possible.

6 Install the battery cables as shown. Position the cables so the battery caps can be easily

removed for battery service.

7 Carefully tighten the nut in each battery terminal until the terminal will not turn. Do not

over-tighten the terminals, or they will be very difﬁ cult to remove for future service.

8 Coat the terminals with spray-on battery terminal coating (available at most auto parts

stores).

9 Put one of the black rubber boots over each of the terminals and connect the Battery

Pack Connector (15).

When changing batteries or the charger, please contact your local authorized service center for correct battery, charger and machine settings to prevent battery damage.

FILLING THE SOLUTION TANK

Fill the solution tank with a maximum of 21 gallons (79.5 Liters) for SC750/SC750 ST models and 25 gallons (94.6 Liters) for SC800/SC800 ST models of cleaning solution. Do not ﬁ ll the solution tank above 7.5 cm (3 inches) from the bottom of the Solution Fill (1). The solution should be a mixture of water and the proper cleaning chemical for the job. Always follow the dilution instructions on the chemical container label. NOTE: EcoFlex machines can either be used conventionally with detergent mixed in the tank or the detergent dispensing system can be used. When using the detergent dispensing do not mix detergent in the tank, plain water should be used.

CAUTION!

Use only low-foaming, non-ﬂ ammable liquid detergents intended for machine application. Water temperature should not exceed 130 degrees Fahrenheit (54.4 degrees Celsius)

SQUEEGEE INSTALLATION

1 See Figure 5. Slide the Squeegee Assembly (12) onto the squeegee mount bracket and tighten the Squeegee Mount Thumb Nuts (22). 2 Connect the Recovery Hose (16) to the squeegee inlet. 3 Lower the squeegee, move the machine ahead slightly and adjust the squeegee tilt using the Squeegee Adjustment Knob (23) so that the

rear squeegee blade touches the ﬂ oor evenly across its entire width and is bent over slightly as shown.
