17
Machine Overview
1.5 Operation Modes
1. Regular Scrub Mode
When the machine is running in this mode, the machine will perform all operations. This mode can be used for day-to-day tasks under nor­mal conditions. When the operator sets the directional switch to for- ward and activates the accelerator pedal, the solution pump will turn on, the brushes will turn on and be lowered to the floor, as well as the rear squeegee. While operating in this mode, the solution will be dis­persed into the brushes, which will scrub the floor allowing the chem­ical in the solution to break down the dirt on the floor. As the machine continues to move forward, the rear squeegee and vacuum system will recover the dirt and dispensed solution. If the operator stops mov­ing, the machine will automatically raise the scrub deck and turn off the brushes. If the directional switch is changed to reverse the ma­chine will continue to operate normally, only the rear squeegee will raise up.
2. Heavy Scrub Mode
This mode is similar to Regular Scrub. The machine will continue to operate the same was as if it was in Regular Scrub Mode, only this mode applies more solution and brush pressure is increased. This mode is used for high traffic areas and areas that have been heavily soiled, but do not require time for the solution to soak.
3. Double Scrub Mode When the machine is running in this mode, the machine will perform all operations except dirty solution recovery. This mode can be used
if the floor is heavily soiled and the chemical will need additional time to emulsify grease and oils that are on the floor. When the operator sets the directional switch to either the forward or reverse position and activates the accelerator pedal, the solution pump will turn on, the brushes will turn on and be lowered to the floor. While operating in this mode, the solution will be dispersed into the brushes, which will scrub the floor allowing the chemical in the solution to break down the dirt on the floor. As the machine continues to move forward or back, the rear squeegee and vacuum system are not on, which allows the
18
solution to stay on the floor emulsifying the grease and oil. If the op­erator stops moving in either direction, the machine will automatically raise the scrub deck and turn off the brushes. After double scrubbing, the operator should use the vacuum only mode to recover the dirty solution water from the floor.
4. Vacuum Only Mode
When the machine is running in this mode, the machine will only low­er the rear squeegee and turn on the vacuum system to recover the dirty solution from the floor. This mode is usually chosen after double scrubbing to recover the dirty solution but it can also be used to pick up spills. When the operator sets the directional switch to forward, the rear squeegee will be lowered to the floor as the vacuum turns on, pulling the dirty solution water from the rear squeegee into the recov­ery tank. If the operator stops moving forward and sets the directional switch to reverse, the rear squeegee will retract (protecting it from damage) and the vacuum motor will turn off after a few seconds. If the operator quits moving in either direction, the machine will automati­cally raise the squeegee and turn off the vacuum motor after a few seconds.
5. Transport Mode
When the machine is set in this mode, none of the cleaning functions of the machine will operate. This mode is only used to transport the machine from one location to another.
6. Solution Control Knob
This control will adjust the amount of solution that is being dispersed to the floor while in one of the scrub modes. Adjust the control clock­wise to increase the amount of solution being dispersed. The amount of solution applied is variable to a maximum of 1 GPM.
7. Battery Gauge
This gauge displays the level of charge remaining in the machine’s batteries. The gauge consists of 10 LEDs. (3 Green, 4 Amber, 3 Red) If the battery life is low, the battery gauge bar icon will be flashing to
m th
infor
e operator that the machine is almost out of power. Once this
Machine Overview
signal is displayed, all functions will shut off, including transport mode. The operator must then turn the key switch OFF and then ON to reset the machine. The machine will then have only a few minutes left of reserve power to briefly use Vacuum Only mode to pick up any remaining solution on the floor and Transport mode to return to the charging station. This gauge will also display a fault code if the sys­tem has an error. This code is represented by a specific number of flashing LEDs. See Fault/Diagnostic Codes for specific code informa-
tion.
19
Machine Overview
1.6 Fault/Diagnostic Codes
When an error or fault occurs within the machine, a fault code will ap­pear on the battery gauge represented by a specific number of flash­ing LEDs. The figure below shows a listing of the different codes.
Low Battery Indicator
If the battery life is low, the battery gauge bar icon will be flashing to inform the operator that the machine is almost out of power. Once this signal is displayed, all functions will shut off, including transport mode. The operator must then turn the key switch OFF and then ON to reset the machine. The machine will then have only a few minutes left of reserve power to briefly use Vacuum Only mode to pick up any
remaining solution on the floor and Transport mode to return to the charging station.
Power Save Mode
The E Ride is equipped with a power save feature to conserve battery power. If the key switch power is left ON and none of the controls are activated for a period of fifteen minutes, the E Ride automatically goes into “power down mode” and turns OFF the power to conserve your batteries in case the operator forgets to turn the key switch off or leaves the machine unattended.
Empty Solution Tank Indicator
Once the solution tank has become empty, the battery gauge will blink a solid 9 LEDs at a constant interval to alert the operator that the solution tank needs to be filled.
20
Machine Overview
1.7 Steering Wheel
The steering wheel is adjustable for operator comfort by pulling the tilt-steering lever up and positioning the steering wheel up or down (there are three possible positions). Pulling on the tilt-steering lever and position- ing the steering column in an upright position provides the operator with more room when climbing up and down the machine.
1.8 Accelerator Pedal - R1
Located on the right side of the operator compartment on the floor is the accelerator pedal. This pedal controls the propelling speed of the machine. The farther the pedal is pushed down the faster the machine will travel. As discussed earlier, the directional
switch governs the direction of travel the ma­chine will take. Switching the directional switch with the pedal depressed will make your machine change directions (a very slight delay may occur before the direction of travel changes when switching directions on the fly). The accelerator pedal is interlocked with the seat switch, making machine propul­sion not possible without the operator sitting on the seat. The accelerator pedal is also linked to the machine’s dynamic braking sys- tem. During operation, when the accelerator pedal is released, the dynamic braking sys­tem will automatically halt the movement of the machine without need for an additional brake pedal.
1.9 Seat - S8
The ergonomically designed seat is located on top of the solution tank. There is a lever under the seat that allows the operator to ad­just the seat forward or backward for opera­tor comfort. There is an interlock switch located inside the seat. This makes it impos­sible to engage the traction drive circuitry without the operator on the seat. If the oper­ator were to fall off the machine, the traction drive circuitry would turn off.
1.10 Directional Switch - S6
Located on the lower front of the control con­sole, this switch controls the direction in which the E Ride will move when the accel- erator pedal is activated. Flipping this switch to the down position will set the machine to move forward. Flipping it to the up position
sets the machine to move in reverse.
1.11 Parking Brake
This machine is equipped with an Electro­magnetic brake built-in on the traction drive
motor. When the machine’s power is turned off (using either the key or the emergency button), the E-mag brake is activated and the traction motor is prevented from moving.
21
Machine Overview
1.12 Circuit Breakers
The circuit breakers are located on the front panel under the seat. The 6-amp breaker (CB2) protects all auxiliary circuits on the machine. The 100-amp breaker (CB1) pro- tects the main system circuit (TRIO control­ler). On the cylindrical models only - The two 30-amp breakers (CB3 & CB4) protect the cylindrical brush deck motors. Each main component is individually protected with an
internal breaker built-in the controller. (See fault code table) and can be
reset by turning the key switch off a few sec­onds and then on again. The 100 amp circuit breaker can also be used as a main power disconnect, this should be used only in case of emergency. When tripped the breaker re­moves power from the main controller and all auxiliary power circuits.
1.13 Battery Compartment
The battery compartment is located on the rear of the machine under the recovery tank. Unlatching the two safety latches on the side of the machine enables the operator to tilt the recovery tank and access the batteries for servicing and maintenance (make sure recovery tank has been drained before tilt­ing). The battery compartment contains six, 6-volt batteries connected in series. Connect the batteries according to the battery con­nection diagram (see diagram). The recom­mended batteries are 235Ah (Minuteman P .N. 956740). The two batteries positioned in the center are offset and held in position by two steel spacers. These spacers keep the batteries from sliding inside the battery com­partment during machine use and prevent undesired stresses in the battery cables. Be sure to replace these spacers whenever re­installing batteries.

1.14 Scrub Decks
Minuteman offers two deck types (Cylindrical and Disc) to fit your specific needs. The E
Ride design is very dynamic wherein the decks are interchangeable in a matter of minutes whenever necessary (removal of four bolts, one hose, and one electrical con­nection). The cylindrical brush deck has five built-in spray jets to uniformly dispense cleaning solution on the floor and a wet sweeping debris tray to collect loose objects on the floor. The disc brush deck dispenses cleaning solution through the two center hubs and the solution is contained within the bristle area for efficient agitation of cleaning solution to the floor and channeled to the rear of the machine. The disc brushes are also easily removed and installed by easily removing the side deck covers and releasing the scrub brush quick release clamp. Anoth­er nice feature that these scrub decks have is the ability to have uniform brush pressure applied to the floor at all times. Since the scrub deck brush pressure is computer con­trolled, it will automatically adjust and com­pensate to uneven contours on the floor while maintaining brush pressure.

1.15 Scrub Deck installation
When installing a cylindrical deck to a machine:
1. Install brushes after the deck has been mounted to avoid flat spots on the brushes.
2. Use a piece of cardboard underneath the deck to prevent scratches to the painted surface when sliding the deck under the machine.
3. Make sure the scrub deck is oriented correctly with the spray jets towards the front of the machine. When installing a disc scrub deck to a machine:
1. Install brushes on the scrub deck; this aids the installer in sliding the deck assembly into position.
2. Make sure the scrub deck is oriented correctly with the solution hose tee fitting towards the front of the machine.
Installation Instructions
1. Park the machine on a flat or level surface.
2. Turn the key switch to the ON position and select the transport mode with mode selector knob.
3. Slide the scrub deck assembly underneath the machine (follow instructions as described above)
4. Position the scrub deck to align the mounting brackets with the mounting lugs on the lift linkage.
5. Lower the lift linkage to the floor by pressing the manual overrride switch for five seconds. (see figure)
6. Lower the lift linkage mounting lugs until they barely touch the scrub deck mounting brackets.
7. Fasten with (4) 711242 bolts, 711515 flat washers and 711546 lock washers.
8. For cylindrical scrub deck only: a. Remove the yellow 3 sided knob on the side squeegee assembly and swing out the side squeegee to reveal the access door. b. Remove the two access doors (one on each end) by removing the three wing nuts on
each door. c. Install the brushes by sliding them through the access opening. (see figure for correct orientation.) d. Align the notches on the brush with the drive pins on the hub. e. Push the brush all the way in until it bottoms out. f. Insert the access door hub into the other end of the brush. g. Reinstall the wing nuts and yellow 3 sided knobs and tighten.

Machine Overview
Cylindrical scrub brushes must be installed with the chevron pattern pointing away from each other for best water and debis pick up
Important Note when Interchanging Scrub Decks
As previously mentioned, the scrub deck brush pressure is computer controlled. However, when interchanging the two types of decks, an ad­ditional step must be taken to ensure that the controller correctly compensates the pressure for the type of deck that is currently installed.
Inside the main electrical box, beneath the seat there is an Orange/Violet jumper wire (shown disconnected in Figure 1) that may or may not be connected to the terminal block, depending on the type of scrub deck that was originally ordered with the machine. When using the Disk Scrub Deck, the wire is disconnected. When using the Cylindrical Scrub Deck, the wire is connected to the terminal block located in the electrical box, beneath the TRIO Controller. This terminal block is divided into five sections, each separated by a divider. The four leftmost sections contain one column each of spade terminals. The section on the right contains two columns of spade terminals (this section also contains four Red/Black wires, not shown in Figure 2 for clarity). The Orange/Violet wire must be connected to a spade terminal in the section with two columns when using the Cylindrical Scrub Deck ONLY!
When switching from the Cylindrical Scrub Deck to the Disk Scrub Deck, be sure to disconnect the Orange/Violet wire. When switching from the Disk Scrub Deck to the Cylindrical Scrub Deck, connect the Orange/Violet wire to any available spade terminal in the section that contains two columns (shown in Figure 2) and the Red/Black wires.

Machine Overview
1.16 Side Squeegees
The side squeegees (left and right) are attached to the scrub decks. These items channel the dirty solution to the rear squeegee, helping contain the water within the ma­chine’s cleaning path. These squeegees are raised when the scrub deck is in the raised position.
The side squeegees are pre-adjusted at the factory. Adjust­ments may be required when replacing worn blades or to achieve optimum performance for different floors and con­ditions.
To adjust the side squeegees, simply loosen the mounting hardware (two wing nuts for Disk Scrub Deck, two black three-sided knobs for Cylindrical Scrub Deck). Lower the scrub deck by switching to a scrubbing mode and when the brushes start up, turn off the key switch. At this point the side squeegees should be resting vertically (no deflection) on the floor. Press down on the side squeegee bracket as­sembly from each end while making sure that the blade is uniformly deflected in a 45 degree angle along its whole length. Tighten the wing nuts (item A). Turn the steering wheel all the way to the left or right and start pushing the machine to the side to inspect the blade deflection and wip­ing action. Repeat the steps above until a satisfactory result is obtained
.

Machine Overview
Brush Changes On the Cylindrical Deck
In order to change the brushes on the cylindri­cal deck the side squeegee must be moved in order to access the brush doors. The cylindri­cal deck was designed so one can change the brushes without having to realign the side squeegees. This is accomplished by removing the yellow three-sided knob (Item C) and swinging the squeegee along the hinge brack­et (Item D) located at the front of the deck, gaining access to the brushes. Once complet­ed inserting new brushes, replace the brush doors and swing the squeegee back into place, tightening down the knob (Item C).
In order to remove or adjust the alignment of the side squeegees on the cylindrical deck, re­move the black three-sided knobs (Item B) and follow the instructions on the previous page.

Machine Overview
1.17 Rear Squeegee
The rear squeegee is the main element that acts as the conduit that transfers the spent solution into the recovery tank. A daily maintenance check of this component is essential to have optimum machine performance. The rear squeegee assembly is equipped with a universal front blade that allows the operator the option to use a slotted and a non-slotted side for specific applications. Each blade configuration has two usable edges. The rear blade however has four usable edges.
The squeegee is pre-adjusted at the factory. Adjustments may be required to get optimum performance for different floors and conditions.

Machine Overview
Rear Squeegee Adjustment
1. Ensure that the scrubber is on a relatively flat surface. Turn on the key switch and select the Vacuum only mode. This lowers the squeegee to the floor and turns the vacuum motor on.
2. Move the scrubber one or two feet forward slowly while someone behind the machine checks the rear squeegee blade (item A) for uni­form deflection to the floor.
3. If uneven deflection or lay is evident, minor adjustments may be necessary to avoid streaking and uneven wear on the blade.
4. To correct this, loosen the wing jam nut (item B) in order to adjust the caster height. If the squeegee blade is deflecting too much, the casters (item C) need to be lowered to control the down pressure. Lo wer the caster by turning the exposed threaded stem (item P) on the caster clockwise. Make the adjustment a few turns at a time. Repeat step 2.
5. If the blades are not deflecting enough, raise the caster by turn ing the stem co unter-clockwise to adjust t he caster height t o allow mor e down pressure on the squeegee. Repeat step 2.
6. Make sure there is even deflection on the entire length of the rear blade. Adjust the cast ers and retighten the wing jam nuts to lock the caster setting in place.
7. Pitch adjustment is necessary if the outer ends on the squeegee blade do not contact the floor and there is too much deflection in the middle area or if the outer ends are over deflected and there is no contact in the middle.
8. To adjust the pitch, repeat step 2.
9. Loosen the two wing jam nuts (item D) that lock the pitch angle. Turning the knob (item E) clockwise or counter-clockwise controls the forward and backward pitch of the squeegee. Having the rear blades deflected uniformly along its entire length is the desired set-up.
10. Repeat step 2 until desired set-up is achieved.
11. In certain applications where a non-slotted front wiper blade (item F) is needed, detach the rear squeegee assembly by loosening the two wing bolts (item G). Unlock the toggle clamp (item H) on the front squeegee to release the front long strap (item I) and slide the front short strap (item) (J). Flip the blade over to the non-slotted side. Reattach the straps and lock the clamp back in place.
12. You can also easily replace the rear blade by unlatching the latch (item M) and removing the two rear straps (items K & L) by sliding them off the assembly. You can then flip the blade over in order to use a new edge for better wiping action.
