1. Cautions • Always disconnect the A.C. Cord from the outlet and and D.C. Cord from the battery pack before servicing the machine. Except for making voltage lt and d currentt measurements. t • Before replacing or disconnecting any electrical componets, disconnect the battery pack from the machine first. Failure to do so could cause a short circuit. circuit • After any repair work test the machine for proper operation.
2. Maintenance Intervals •Maintenance Intervals: In a modular structure, the Minuteman System Maintenance determines the specific technical proceedures to be preformed and sets the time interval between the two maintenance cycles. For each of the maintenance cycle, the replaceable parts are determined as well. Further details described in the specific chapters.

Once it is in service mode, the deck can raised and lowered by pressing the upper or lower part of the rocker switch. To return the machine back to normal operation: Turn the key switch off and back on. The machine will reset.
4. Brush Pressure Settings The brush pressure range can be changed when changing the type of deck on the SC2832E, SC2426P, CP2832 and ES2832 models. g wire into Connect the orange/violet the terminal block with red/black wire group for cylindrical decks and unplug it for the disk decks.
4.1 ES2832,CP2832, and Phoenix 34 It is now available to change the brush pressure settings in the field, when changing brush decks on current production models of the Easy Scrub 28 and 32. No other modifications will be required. Changing the brush pressure settings will only be required, when changing the cylindrical over to the disk deck or disk over to the cylindrical decks. Changing the size only (Example: Changing the 28 disk to 32 disk) will not require changing the settings.

9. Trouble Shooting the Code 8 Error ES2832, CP2832, SCV2426 and SC2832E Models Only) 1. Check for loose or burnt connections on the controller, batteries, cables and the circuit breaker. Make the sure the circuit breaker is not damaged. 2. Measure the total battery voltage at the batteries and at the battery connections on the controller. They should be exactly the same. A 1/10 of a volt or more difference would indicate a problem in the connections. 3.
9. Trouble Shooting the Code 8 Error 6. Disconnect one motor connector from the Trio controller at a time and disconnect the batteries for 1 minute and restart the machine. If the code 8 disappears and is replaced by a different code, the circuit disconnected should be considered suspect. For example the brush was disconnected. The code 8 is replaced by code 3. Code 3 indicates the brush motor is disconnected Check for a loose or broken connection at the brush deck disconnected. deck.
10. Testing the Throttle Potentiometer 1. 2. 3. 4. 5. 6 6. 7. The throttle potentiometer resistance can be measured with an ohmmeter. Unplug g the throttle potentiometer at the connector next to it. Analog type meters are recommended for this test. Measure the resistance across the red and white wire on the potentiometer assembly. It should measure approximately 5K (5 thousand ohms).
10. Testing the Throttle Potentiometer 8. If they do not find a problem here, have them retest at the connector at the Trio controller. 9. Reconnect the plug at the throttle potentiometer. 10. Unplug the P3 connector (The large white connector) on the controller under the seat on the riders and behind the two rear panels on the ES2832s and CP2832s. 11 L 11. Locate t th the bl black/orange k/ and d th the bl black/pink k/ i k wire. i 12.
11. Identifying the Cause of Trio Failures 1. 2. 3. Check for loose or burnt connections on the controller, batteries, cables and the circuit breaker. Make the sure the circuit breaker is not damaged (burnt or cracked). Test the chassis drive motor harness for broken wires (riders only). Disconnect the plug labeled Traction on the Trio controller. Connect a digital multi-meter to the plug on the two large wires. Set the meter for Ohms (resistance). The resistance should be .3 to .4 ohms.
