INTRODUCTION
This manual will help you get the most from your Advance Scrubber. Read it thoroughly before operating the machine.
Note: Bold numbers in parentheses indicate an item illustrated on pages 8 – 12.
This machine is intended for commercial use, for example in hotels, schools, factories, shops, ofces and rental businesses. The Advance
SC4000 is a battery powered oor cleaning machine.
WARNING:
The operation of this machine is strictly reserved to trained and qualied operators.
CAUTION!
• Use extreme CAUTION when operating this machine. Be certain that you are thoroughly familiar with all operating
instructions before using this machine. If you have any questions, contact your supervisor or your local Advance Dealer.
• If the machine malfunctions, do not try to correct the problem unless your supervisor directs you to do so. Have a
qualied company mechanic or an authorized Advance Dealer service person make any necessary corrections to the
equipment.
• Use extreme care when working on this machine. Loose clothing, long hair, and jewelry can get caught in moving parts.
Turn the Power Switch OFF and remove the magnetic key before servicing the machine. Use good common sense,
practice good safety habits and pay attention to the yellow decals on this machine.
• Drive the machine slowly on inclines.
• The maximum rated incline for scrubbing is 9% (5°). The maximum rated incline during transport is 16% (9°).
PARTS AND SERVICE
Repairs, when required, should be performed by Nilsk, Inc., who employs factory trained service personnel, and maintains an inventory of
Advance original replacement parts and accessories.
Call Nilsk, Inc. for repair parts or service. Please specify the Model and Serial Number when discussing your machine.
MODIFICATIONS
Modications and additions to the cleaning machine which affect capacity and safe operation shall not be performed by the customer or user
without prior written approval from Nilsk, Inc. Unapproved modications will void the machine warranty and make the customer liable for any
resulting accidents.
NAME PLATE
The Model Number (also known as Part Number) and Serial Number of your machine are shown on the Nameplate, located on the rear of the
steering column.
Date of Manufacture “Date Code” is marked on the nameplate. Date Code: A21, means January 2021.
This information is needed when ordering repair parts for the machine. Use the space below to note the Model Number and Serial Number of your
machine for future reference.

MAGNETIC SmartKey™
The use of a Magnetic SmartKey (39) is required to operate this machine. Pressing the power switch without a key in place on the SmartKey
Reader (22) will cause the machine to momentarily turn on and display No Key Indicator (C21) before turning off.
There are two different Magnetic SmartKeys (39).
1. The “User” (blue) key allows a basic level of access to the information menu (press Information Switch (B)).
2. The “Supervisor” (yellow) key allows an additional level of access to see Options Menu.
FIGURE 1-1
PREPARE THE MACHINE FOR USE
LEAD-ACID BATTERIES
If your machine shipped with batteries installed do the following:
• Check that the batteries are connected to the machine.
• Turn ON the Power Switch (H) and check the Battery Indicator (C3). If the gauge is completely lled the batteries are ready for use. If the
gauge is less than full the batteries should be charged before use. See “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.
LEAD-ACID BATTERY INSTALLATION
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 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 rst when replacing batteries to prevent sparks.
•ALWAYS connect the negative cable last when installing batteries.

LEAD-ACID BATTERIES - CONTINUED
CAUTION!
Electrical components in this machine can be severely damaged if the batteries are not installed and connected properly.
Batteries should be installed by Nilsk or by a qualied 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 le a damage claim.
2 Turn the Power Switch (H) OFF and remove the Magnetic SmartKey (39).
3 Rotate the Battery Compartment Latch (20) to unlock then tip the seat forward (the gas spring holds the seat open).
4 For additional access the recovery tank can be removed from the machine. NOTE: Disconnect the recovery hose, vacuum motor wiring and
warning beacon wiring then lift the tank straight up and off the machine, using two people or an overhead hoist.
5 Your machine comes from the factory with enough battery cables to install three 12 volt batteries. Using at least (2) people and an
appropriate lifting strap, carefully lift the batteries into the battery compartment and arrange them exactly as shown in FIGURE 2-1. Secure
the batteries as close to the rear and right side of the machine as possible. Use battery spacer to keep batteries from moving. If installing a
mono-block battery use an overhead hoist.
6 Install the battery cables as shown. Position the cables so the battery caps can be easily removed for battery service.
IMPORTANT!: The protective caps supplied with the batteries need to be left on or re-used to completely cover the portion of the
battery terminals that are not being protected by the battery cable terminal cover boots supplied with the battery cables. This also
applies to the in-line fuse holder boot.
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 dif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 Machine Battery Connector (19).
10 Make sure the fuse holder boot is covering the fuse holder, the cable end of the Machine Battery Connector (19), and as much of the battery
terminal as possible. Leave the protective caps supplied with the batteries in place or re-use to cover the terminal areas not protected by the
terminal cover boots.
When changing batteries or the charger, please contact your local authorized service center for correct battery, charger and machine
settings to prevent battery damage.
