FUNCTIONAL DESCRIPTION OF CONTROL BUTTONS:
Key Switch (AA) – Main Power Switch, when turned on controls battery input to machine’s main control board and wheel drive speed control.
Battery Condition Indicator (BB) – The Battery Condition Indicator will give an indication of the state of charge of the batteries. Three lights
make up the Indicator Display (Red-Yellow-Green). See the electrical system in this manual for discharge percentage details of each indicator
light.
Hour Meter/Error Display (CC) The 5-character display on the I/O Panel is primarily used as a display for the hour meter function. When the Key
Switch (A) is activated pad pressure setting 1,2, or 3 will appear briefly in the right corner of the display. Followed by five 8’s to show functionality
of the L.E.D. Display, then switching to hours on the unit. This display is also used to display the following information depending upon which
mode the control is in:
• Error Codes*
• Pad Pressure Settings (1,2, and 3)
• Display of control system default parameters*
*Service Note: Have a qualified Service Technician reference the Service Manual for explanations about Error Codes and Control Fault + Parameter Changes. A
description of Error Codes can be found in the electrical section of this manual
Pad Drive Indicator Light (DD) –
• Indicator will be blank (off) when deck is in the raised position.
• Indicator will be light Green when lowering the deck as the pad drive raise-lower switch is activated.
• Indicator will be dark Green when the Drive Pedal is engaged in Forward or Reverse activating the pad motor.
• Indicator will be Red when raising the deck as the pad drive/raise-lower switch is activated.
• At full raised position the Red light will go out.
Pad Drive Raise-Lower Switch (EE) – Pressing this switch will activate (turn on) the Lower/Raise burnishing deck lift actuator functions – see
indicator lights description for further information.
Horn Indicator Light (FF) – Indicator Light will turn Green when Horn Switch is depressed. And also displays fault flash codes. NOTE: See
electrical system Curtis Control diagnostics in this manual.
Horn Indicator Switch (GG) – Pressing this switch will activate (turn on) the horn, causing a horn like sound to emanate from the machine.

BURNISHING SYSTEM
FUNCTIONAL OVERVIEW
The machines: Advolution 2710 / UHR 70-1700 (Model numbers 56422000, 56422001 & 56411002) use the disk type burnishing system. The pad
driver assembly is directly attached to a single 3.25hp – 36v DC permanent magnet motor.
The burnishing deck is raised and lowered by a horizontally mounted electric lift actuator motor. The operation of the machine’s burnishing
functions are activated when the operator presses the main I/O Panel’s pad drive raise/lower switch (EE). NOTE: See the Electrical System-
Advolution programming modes section of this manual for more detailed operation and instructions to change the burnishing pad pressure setting.
The machines main burnishing system input and output operating functions are regulated (managed) by the I/O Panel and the Control Box. For
the Pad motor to function the operator must turn on (energize) the (K1) pad motor solenoid by pressing the Pad drive Raise/Lower switch (EE) on
the I/O Panel and press the drive pedal moving it off it’s neutral position. These two operator functions deliver the required (A1) Speed control and
Control Box circuit inputs and outputs for the burnishing operation. NOTE: See troubleshooting (page 22) section for more details.

PAD LIFT ACTUATOR REMOVAL AND INSTALLATION
WARNING!
Disconnect the battery pack by separating the battery connectors (7) whenever servicing the machine.
1 Disconnect the battery pack by separating the battery connectors (7) located underneath the drivers seat.
2 Disconnect the actuator wiring harness at the actuator lift motor.
3 See Figure 1. Remove the (2) Hex Screws (A) that fasten the actuator Mount Bracket (B).
4 Remove the Retainer Ring (C). NOTE: Remove the retainer closest to the front of the machine. Then slide the mount pin (D) to the rear to
allow removal of the Actuator (E) from the machine.
5 To re-install follow the above instructions in reverse order. NOTE: See the Actuator Lift Nut Adjustment section in this manual for correct
lift nut adjustment setting as new actuators do not come pre-set.
PAD DRIVE DECK REMOVAL
WARNING!
Disconnect the battery pack by separating the battery connectors (7) whenever servicing the machine.
1 Disconnect the battery pack by separating the battery connectors (7) located underneath the drivers seat.
2 See Figure 1. Remove the (2) Deck Springs (F) from the right side of the lower deck housing. NOTE: Use a pliers to assist in disconnecting
the springs. Having the deck in the up position will also make it easier (less tension).
3 Attach the Advance actuator adapter cord (P.N. 56407502) to the deck Actuator (E) and lower deck. This step is done to gain service access
to the motor wiring and lift linkage mount hardware.
4 Disconnect the deck’s Safety Switch (G) at its harness connector.
5 Remove the (2) pad motor wires. NOTE: Mark the Red (-) & Black (+)wire locations.
Service Tip: Measure the height of the Front to Back Deck Level Adjustment Screw (H) before disassembling (should be approximately 1-
1/8”(28.44mm)).
6 Loosen Lock Nut (I) and thread it down. At the same time remove the Adjustment Screw (H) from the Pivot Shaft (J).
7 Tap the Shaft (J) toward the rear tire to complete its removal.
Service Tip: The shaft is spaced with (2) Nylon Washers (K), note their location for reassembly.
8 Slide the deck assembly out from under the machine.
PAD DRIVE MOTOR CARBON BRUSH INSPECTION
1 Follow instructions for Pad Drive Deck Removal.
2 See Figure 1. Remove the Motor Air Filter (L). NOTE: Inspect the condition of the filter band and clean or replace as needed.
3 Remove the motor Brush Cover (M) secured by (4) Phillips head screws (N).
4 Inspect carbon brushes and springs. NOTE: New carbon brushes measure 1-3/32 (28mm). If the brushes are less than 3/8” (10mm) long
they should be replaced.
5 Important Maintenance Tip: Always blow out motor before reassembling
6 Motor wiring tip: The Red cable goes to NEGATIVE Stand off on the motor and the Black cable goes to the POSITIVE Stand off on the
motor.

2Place your hand underneath the Dust Control Shroud (2) and remove the Pad Retainer (4) from the flexible pad holder assembly. NOTE:
Grip the retainer firmly and turn clockwise (to the right) as the retainer uses a Left Hand thread.
3Select a 27 inch (68 cm) Dia. Burnishing Pad (A). See your local Nilfisk-Advance Distributor for a complete selection of pads and
accessories.
4Insert the plastic Pad Retainer (4) into the center of the Pad (A). Then reinstall by turning the retainer counter-clockwise (to the left). NOTE:
Important !!! Turn the retainer in until you hear a clicking ratchet sound, this insures proper tightening of the pad by properly compressing the
pad material and drawing up the retainer so it will not strike the floor.
