How to tell which you have
- Model number: the Model Number (also called the Part Number) and the Serial Number are on the nameplate in the battery compartment. The models are 56115530 (SC901 ST-28D), 56115531 (SC901 ST-34D) and 56115532 (SC901 ST-32C).

- NEXSYS: Advance's parts list also covers the 28D NEXSYS (56115534) and 34D NEXSYS (56115564). Its operator manual lists only the three models above, and the parts list marks one line as NEXSYS only.
- EcoFlex: the detergent module on the control panel is on EcoFlex models only. The parts list marks only the Decal System lines as STD or EcoFlex models.
How to read this list
Our part numbers are the Advance number with AD in front, so Advance 56115334 is AD56115334. Where Advance prints a letter at the end of a number (for example 54647A), we keep it. Each line shows the item number on the drawing. Blue part numbers open the part page. Lines marked Call to confirm part are not listed online yet; call 800-440-6723 and we will source them. Lines marked No number printed are parts Advance prints without a part number. Its ordering instructions say to order the service kit that contains the part, and the note on the line names that kit. Prices were current on ; your cart always shows the current price. Have your machine serial number ready when you call.

New to your Advance SC901 ST? Start here
Set up, run and look after your SC901 ST. Everything here comes from Advance's instructions for use, rewritten in plain steps, with the parts you need linked to the list above.
1Check the batteries
- Check that the batteries are connected to the machine.
- Turn the key switch on and read the battery and hour gauge. A 10-segment bar shows the charge, empty on the left and full on the right.
- Charge the batteries fully before each use.
- Check the charger maker's manual for the battery type setting if your machine has an onboard charger.

2Fill the tank and fit the squeegee
- Fill the solution tank with no more than 30 gal (113.5 L) of water mixed with the right cleaning chemical. Follow the dilution on the chemical label.
- Use only low-foaming, non-flammable liquid detergents made for machines. Keep the water at or below 130 °F (54.4 °C).
- Slide the squeegee onto the squeegee mount bracket and tighten the thumb nuts by hand. Do not use tools.
- Connect the recovery hose to the squeegee inlet.

3Fit the brushes or pads
- Turn the key switch off and remove the key. Make sure the scrub deck is raised.
- Disc models: put the pads on the pad holders (AD56505800 / AD56505780) if you use pads. Line up the lugs on the brush with the holes in the mounting plate and turn to lock. Turn the outside edge of the brush toward the rear of the machine.
- Cylindrical model: loosen the black knob on top of each idler assembly and remove the idler assemblies. Slide the brush into the housing, lift slightly, then push and turn until it seats.
- Put the idler assemblies back on.

4Scrub the floor
- Turn the key switch on. Push the drive paddle forward to go forward or pull it back to reverse. The speed control knob sets the top speed.
- Lower the scrub deck with the deck lever. The machine is ready to scrub when it starts to move.
- Lower the squeegee with the squeegee lever. The vacuum motor turns on when the squeegee goes down.
- Keep the machine moving while the brushes turn, at a slow walking speed. Standing still can damage the floor.
- On a ramp, clean only while you drive up it. Avoid sudden stops and abrupt sharp turns.

Common Advance SC901 ST parts questions
What happens when the Advance SC901 ST batteries run down?
The gauge flashes the second LED from the left at 70% discharge. At 80% discharge it flashes the left two LEDs in turn and the scrub systems shut off to protect the batteries. The vacuum keeps running so you can pick up the solution left on the floor.

When do the SC901 ST squeegee blades need replacing?

Notes on this parts list
Places where Advance's documents disagree, and how this page handles them. If you are unsure, call 800-440-6723 with your serial number.
- Advance's parts list covers five models: 56115530, 56115531 and 56115532 plus the 28D NEXSYS 56115534 and 34D NEXSYS 56115564. The instructions for use list only the first three.
- Lines with a Kit mark and no part number are printed that way in the parts list. We show them as No number printed and name the service kit in the note. The service kits are listed at the end of each section.
- Control System item 7 is printed as DELETED and Recovery System item 3 as Intentionally Omitted. Neither has a part number or a callout, so neither is on this page.
- Control System item 8 is printed twice: 56115296 with no model mark and 56115582 marked NEXSYS ONLY. Both are on this page, and only the NEXSYS line is tagged to a model.
- Decal System items 4 and 5 are both printed as 56115518. Item 4 is Decal-SC901 (STD Models) and item 5 is Decal-SC901-Advance. Item 4 also lists 56115519 for EcoFlex models.
- Solution System item 47 has no callout on the drawing. Electrical System item 9 (Harness, 56115278) is printed as not shown.
- Scrub System-Disc item 28 (Latch Assembly, 56115427) is printed on two lines with the same number and quantity.
- Squeegee Assy item 1 prints 56115333 as Squeegee Kit-Blade-Linatex for the 32 in cylindrical model. The blade kit lists on pages 23, 28 and 29 print the same number as Squeegee Kit-Blade-Red Gum.
- Options & Accessories prints the pad retainer 56505195 as Pad Retainer for 56505750 under both disc sizes. The brush selector guide (page 30) prints it as Pad Retainer for 56505800 under both.
- Options & Accessories (page 28) calls 56407474 Hard Nylon. The cylindrical brush selector guide (page 31) calls it Stiff Nylon.
- The solenoid seal kit is 56118185 on the scrub system pages and 56116891 on the recommended spare parts page. The solenoid valve kit is 56116875 on the scrub pages, and the spare parts page lists Valve-Solenoid-36vdc 56116248.
- The instructions for use (page A-16) tell you to install the heavy duty scrub kit, P/N 56115458, for the high scrub position. The parts list names 56115458 Scrub Spring Kit (Disc Models Only).
- The instructions for use give the solution tank fill limit as 30 gallons (113.5 Liters) on page A-13 and the tank capacity as 30 gallons / 113.6 L on page A-23.
- The specification table (page A-23) prints maximum scrub speed and maximum transport speed as 3.2 with no unit, so they are not on this page.
- The parts list does not print the Detergent Kit number on the Detergent Kit page. Options & Accessories lists Detergent-Kit as 56115383.
- Page 1 of the parts list shows an ordering example (a solution tank, a hinge plate and a solution tank hardware kit) whose numbers belong to another machine. They are not part of the SC901 ST lists and are not on this page.
- Descriptions are copied as Advance prints them, including its spellings (for example Hose-Sprial-.500) and the asterisk in front of Scr Hex Ss M12-1.75 x 100mm on Scrub System-Disc item 13.
