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 brieﬂ y in the right corner of the display. Followed by ﬁ ve 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 qualiﬁ ed 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 ﬂ ash 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 SystemAdvolution 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.

BURNISHING SYSTEM 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 11/8”(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 ﬁ lter 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.

BURNISHING SYSTEM PAD DRIVE MOTOR REMOVAL

1 Follow instructions for Pad Drive Deck Removal. 2 See Figure 2. Remove the Dust Bag (A). 3 Tip the deck assembly over and remove the Pad Retainer (B), pad (if installed) and the Motor Shaft Screw (C) that fastens the Pad Driver

Assembly (D) to the motor shaft. 4 Remove the Pad Driver Assembly (D) from the motor shaft. NOTE: Do not lose the motor shaft key. 5 Remove the (4) Screws (E) and the Dust Shroud (F). 6 Remove the (4) Screws (G) that fasten the motor to the deck plate. Lift the remaining Deck Assembly (H) off the Motor (I) to complete its

removal. NOTE: Mark motor terminal location for reassembly. 7 Follow the above steps in reverse order to reinstall the Pad Drive Motor.

DUST SHROUD REMOVAL

1 See Figure 2. Remove the Dust Bag (A). 2 Remove the Pad Retainer (B), pad (if installed) and the Motor Shaft

Screw (C) that fastens the Pad Driver Assembly (D) to the motor

shaft. 3 Remove the Pad Driver Assembly (D) from the motor shaft. NOTE:

Do not lose the motor shaft key. 4 Remove the (4) Screws (E) and the Dust Shroud (F).

BURNISHING SYSTEM DUST SHROUD EDGING REPLACEMENT

1 See Figure 3. Remove existing Edging (A) by pulling it away from the Shroud (B). 2 To install start at the rear of the Shroud (B) with one end of the new Edging (A) so that the seam is hidden. Push “U” channel onto Shroud

(B), work edging assembly around Shroud (B).

3 Check that Edging (A) “U” channel is ﬁ rmly in place all around Shroud (B). NOTE: Pinch the “U” channel every 3 to 4 inches with a vise-

grips to ensure it is securely fastened to the shroud.

BURNISHING SYSTEM PAD DRIVE DECK LEVEL ADJUSTMENT

NOTE: Install a new pad before performing this adjustment.

1 Put the pad drive deck in the down position. 2 Brieﬂ y run the pad drive motor to get a pattern on the ﬂ oor.

CAUTION!

Do not run pad motor for an extended period without moving machine.

FIGURE 4

Left to Right Pad Contact Adjustment – See Figure 4.

1 Loosen the (2) Nuts (A) on the Adjustable Bracket (B). 2 Turn the (2) Lock Nuts (C) on the Carriage Screw (D) either

down to increase or up to decrease Dimension “X”.

Decreasing Dimension “X” will increase the pad pressure at

the 3 O’clock position.
