12 - FORM NO. 56043107 - Advolution™ 2710 / UHR 70-1700
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.

4Remove 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.
5To 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.
1Disconnect the battery pack by separating the battery connectors (7) located underneath the drivers seat.
2See 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).
3Attach 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.
4Disconnect the deck’s Safety Switch (G) at its harness connector.
5Remove 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)).
6Loosen Lock Nut (I) and thread it down. At the same time remove the Adjustment Screw (H) from the Pivot Shaft (J).
7Tap 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
1Follow instructions for Pad Drive Deck Removal.
2See Figure 1. Remove the Motor Air Filter (L). NOTE: Inspect the condition of the filter band and clean or replace as needed.
3Remove the motor Brush Cover (M) secured by (4) Phillips head screws (N).
4Inspect 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.
5Important Maintenance Tip: Always blow out motor before reassembling
6Motor 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.

PAD DRIVE MOTOR REMOVAL
1Follow instructions for Pad Drive Deck Removal.
2See Figure 2. Remove the Dust Bag (A).
3Tip 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.
4Remove the Pad Driver Assembly (D) from the motor shaft. NOTE: Do not lose the motor shaft key.
5Remove the (4) Screws (E) and the Dust Shroud (F).
6Remove 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.
7Follow the above steps in reverse order to reinstall the Pad Drive Motor.
DUST SHROUD REMOVAL
1See Figure 2. Remove the Dust Bag (A).
2Remove the Pad Retainer (B), pad (if installed) and the Motor Shaft Screw (C) that fastens the Pad Driver Assembly (D) to the motor shaft.
3Remove the Pad Driver Assembly (D) from the motor shaft. NOTE: Do not lose the motor shaft key.
4Remove the (4) Screws (E) and the Dust Shroud (F).

DUST SHROUD EDGING REPLACEMENT
1See Figure 3. Remove existing Edging (A) by pulling it away from the Shroud (B).
2To 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).
3Check that Edging (A) “U” channel is firmly in place all around Shroud (B). NOTE: Pinch the “U” channel every 3 to 4 inches with a visegrips to ensure it is securely fastened to the shroud.

PAD DRIVE DECK LEVEL ADJUSTMENT
NOTE: Install a new pad before performing this adjustment.
1Put the pad drive deck in the down position.
2Briefly run the pad drive motor to get a pattern on the floor.
CAUTION!
Do not run pad motor for an extended period without moving machine.
FIGURE 4
Left to Right Pad Contact Adjustment – See Figure 4.
1Loosen the (2) Nuts (A) on the Adjustable Bracket (B).
2Turn 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.
Increasing Dimension “X” will increase the pad pressure at the 9 O’clock position.
NOTE: As a general rule the measurement at the 3 o’clock and the 9 o’clock position should be the same when measured from the floor to the edge of the dust shroud.
