THE CONTROL CONSOLE
For operator ergonomics, the control console houses all the primary function buttons are
grouped in a central area. The key switch, main keyboard, directional switch and off-aisle
wand switch are clustered in the back area. The directional switch (forward and reverse) is
located in front of the console for easy fingertip operation.
Accelerator Lever
(A) Enables the machine to move forward or backwards once depressed.
Speed Control
(B) This knob controls the rate at which the machine moves. Turning the knob clockwise will
increase the speed. Turning the knob counter-clockwise will decrease the machine speed.
Directional Switch
(C) When you flip the switch down, the machine moves backwards or flip the switch upward,
the machine will go forward.
Directional Indicator
(D) This indicator displays which direction the ES 2832 will travel once the Accelerator Lever
is depressed. A light is available for each direction. Amber when set to forward. Red when
set to reverse.
Key switch
(E) Controls the machine’s power (On/Off) with a key for safety. All operational settings are
retained even when the power is turned off and on. This also serves as a reset switch when
error or fault codes.
Emergency Belly Bar
(F) If this bar is to be depressed it will override the directional switch and force the CP 2832
to go forward. Most useful if backed into a corner or object to prevent from pinching the
operator.
Off-aisle wand switch
(G) On/Off control for the water supply to the wand and vacuum motor. If the switch is in the
On position it will force the battery gauge to blink 6 LEDs to signify the wand is currently on.
Battery Gauge
(H) This gauge displays the remaining battery life. The gauge has a readout of 10 LEDs. 3
Green, 4 Amber, 3 Red. This gauge will also display the fault code if the system has an error
represented by the number illuminated flashing LEDs. See Fault/Diagnostics Codes below for
specific code.
If the battery life is low the battery gauge bar icon will be flashing to signal the operator that
the machine is almost out of power. Once this signal is displayed to the operator, all functions
will shut off including the transport mode. The operator has to turn the key switch OFF and
then, ON to reset the machine. The machine then will only have a few minutes left of reserve
power for a short Vacuum only mode to pick up remaining solution on the floor and Transport
power.
Solution Control
(I) This knob controls the rate at which solution is put down. Turning the knob clockwise will
increase the amount of solution put down. Turning the knob counter-clockwise will decrease
the solution rate. The knob can be adjusted between 0.25 gpm up to 1.1 gpm.
Mode Selector
(J) This switch will toggle between one of the five cleaning modes available on the CP 2832.

5
CLEANING 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 forward
and activates the
accelerator handle,
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 lever, 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 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.

6
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 at a
faster rate of speed.
6. WATER FLOW
Located on the left side of the control console. This knob controls the rate at which water /
solution is distributed to the scrub deck. The farther the knob is turned clockwise the more
water will be distributed.
7. SPEED CONTROL
Located on the right side of the control console. This knob controls the propelling speed of the
machine. The farther the knob is turned clockwise the faster the machine will travel. As
discussed earlier, the directional switch governs the direction of travel the machine will take.

7
OPERATION OF CONTROLS
POWER SAVE MODE
The CP 2832 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 CP 2832 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.
EMERGENCY DISCONNECT HANDLE
This handle is located beneath the control console off center to the
right. When the red emergency handle is pulled, power will be
turned off. Use this button in case of a machine emergency. To
reactivate, return the handle back to its original position, correctly
seated in the receptacle. All operational settings are retained even
when the power is turned off and on.
CIRCUIT BREAKER
The circuit breaker is located under the emergency belly
bar. The 100-amp breaker protects the main system
circuit (controller). 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.
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 275Ah (Minuteman P/N 956740).

8
SCRUB DECK
Minuteman offers two deck types (Cylindrical and Disc) to fit your specific needs. The
CP2832 design is very dynamic wherein the decks are interchangeable in a matter of minutes
whenever necessary (removal of four bolts, and two quick-connects). 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 center hub and 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 with the quick release clamp by using any of the
three access doors. 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.

Align the notches on the brush with the drive pins on the hub.
Push brush all the way until it bottoms out.
Insert access door hub to the other end of brush.
Reinstall nuts and tighten.

11
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.

12
REAR SQUEEGEE ADJUSTMENT
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.
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.
If uneven deflection or lay is evident, minor adjustments may be necessary to avoid streaking and
uneven wear on the blade.
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.
Lower the caster by turning the exposed threaded stem on the caster clockwise. Make the adjustment a
few turns at a time. Repeat step 2.
If the blades are not deflecting enough, raise the caster by turning the stem counter-clockwise to adjust
the caster height to allow more down pressure on the squeegee. Repeat step 2.
Make sure there is even deflection on the entire length of the rear blade. Adjust the casters and retighten
the wing jam nuts to lock the caster setting in place.
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.
To adjust the pitch, repeat step 2.
Loosen the lock nut (item D) in the turnbuckle assembly. Turning the turnbuckle (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.
Repeat step 2 until desired set-up is achieved.
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 (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.
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.

13
OFF-AISLE WAND (optional)
The CP2832 is equipped with a ready-to-use built-in telescoping off-aisle wand system for use in hard to
reach areas. This integrated system eliminates attaching hose for use and detaching hoses for storage. By
turning the pump switch ON (located behind the right handle of the control console) the off-aisle wand is
ready to use in seconds. After use, simply flip the switch OFF and return the wand to it’s original
storage location. The wand is also equipped with the patented flip-flop tool that allows the operator to
switch from scrub brush to squeegee tool by just rotating the tool end.
OFF-AISLE WAND TOOL
The off-aisle wand tool as described in the previous page is composed of the following items:
The recovery hose is connected to the end of the wand on one end and to the recovery tank hose on the
other end. This hose has swivel cuffs on both ends that allow the operator a good range of motion and
the solution hose to be inside the recovery hose.
The trigger controls the solution flow to the spray jet. Squeezing the trigger opens an internal valve to
dispense cleaning solution.
The coiled solution hose acts as a conduit from the trigger to the spray jet, and allows hose to be
extended along with the wand.
The spray jet dispenses the cleaning solution to soak soiled areas that are not accessible to the main
scrub deck.
The telescoping wand allows the length to be adjusted for operator comfort and better storage when not
in use.
Sliding the wand extender forward (as shown above) extends the wand length during use and retracts
the wand by pulling it back for the storage position.
The flip-flop tool gives the operator complete flexibility when changing from the scrub brush mode to
vacuum squeegee mode by simply rotating the end.
When the off-aisle wand switch is turned ON, six LEDs on the battery gauge will
flash to indicate that you are in the off-aisle tool mode. This switch turns on the
pump to supply solution to the wand spray jet and the vacuum motor to recovery
the dirty water.

14
THE CP2832
This machine was designed with total operator comfort and ease of use in mind. All machine
components have been designed as a total system to efficiently clean dirty floors. The CP2832 has four
available scrub head types and sizes to fit specific applications. Please contact your Minuteman
representative for specific recommendations for the correct scrub head type, size, and brush type and
chemical applications.
Before using the machine, always perform the following steps to ensure proper machine operation.
Check under the machine for leaks.
Check the rear squeegee for wear and damage.
Check the solution and recovery tank levels.
After using the machine, always perform the following steps:
Check the battery charge level. Charge batteries if necessary. When charging batteries, extra precaution
is required:
Battery acid can cause burns. When working on or around batteries, always wear protective clothing and
safety glasses. Remove metal jewelry. Do not lay tools or metal objects on top of the batteries.
Charging batteries generate explosive gasses. DO NOT CHARGE BATTERIES WHEN OPEN
FLAMES OR SPARKS ARE PRESENT. DO NOT SMOKE. Make sure the charger is turned off
before disconnecting it from the batteries. Charge the batteries in a well-ventilated area. Fluid levels
should be checked before and after charging and maintained at the proper levels. If low, add distilled
water until the metal plates are covered. If the machine is not used for an extended period of time,
batteries should be kept fully charged with a boost charge once a week.
Check for wire, string, or twine wrapped around the scrub brushes.
Check the rear squeegee for wear and damage.
Check the rear squeegee suction hose and off-aisle wand hose for obstructions.
Empty and clean the debris box (cylindrical systems only).
Drain and clean the recovery tank.
Check under the machine for leaks.
Check the service records to determine maintenance requirements.
WARNING!
Be sure you understand the machine controls and their functions.
While on ramps or inclines, avoid sudden stops when tanks are filled.
Avoid abrupt sharp turns. Slow down driving speed when going downhill.
MACHINE OPERATION
Follow the instructions in preparing the machine for use as described in this manual.
Turn the Key switch ON (I). The Battery Gauge will light up for a few seconds then display the
Battery Condition. Do NOT attempt to operate during this time.
Select one of the five available Modes on the Control Console for the required task. Refer to the Main
Keyboard section of this manual for a complete description of the functions.
Determine the direction you need to travel by selecting forward or reverse on the Directional Switch.
Vary the acceleration knob to propel the machine at the desired speed.
Squeezing the Accelerator Handle turns on the Transport, Brushes, Water Flow, Vacuum and lowers
the Rear Squeegee accordingly to the Mode selected. If the operator triggers the accelerator handle
before, or turns the key switch “ON” at the same time, the machine will not move as a safety precaution.
Simply release the handle and squeeze the handle again to drive the machine. Please refer to the Main
Keyboard section of this manual for a complete description of the functions.

15
When Reverse is selected on the Directional Switch, the Rear Squeegee automatically is raised.
However, the Scrub brushes will continue to rotate and solution will continue to flow.
Start scrubbing by driving the machine forward in a straight line at 3/4 speed and overlap each path by 2
to 3 inches. Adjust your speed and solution flow according to the condition of the floor.
When scrubbing, check behind the machine occasionally to see that all the dirty water is being picked
up. If streaking occurs, your Water Flow setting may be too high, the Recovery Tank may be full, the
Squeegee hose may be clogged, or the Rear Squeegee may require some adjustment or cleaning.
Make the necessary adjustments on the Rear Squeegee if streaking occurs both in straight paths and in
turns. Please refer to the Rear Squeegee section of this manual before making any adjustments.
The recovery tank has an overflow protection to guard against water from entering the vacuum system
when the recovery tank is full. A ball float shut-off system has been integrated into the Recovery Tank.
When the dirty water reaches a certain level, the ball gets suctioned into the vacuum manifold and
blocks the airflow thus, preventing the machine from picking up more liquid. When this happens, the
operator is then required to stop scrubbing and empty the recovery tank.
To stop scrubbing, select the Transport mode. This will automatically stop the Solution Flow, raise the
Scrub deck, and raise the Rear squeegee (there is a 15 second delay for the vacuum motor and a 8
second delay on the rear squeegee).
Drive the ES to a designated dirty water disposal area and empty the Recovery tank. To empty, remove
the Drain hose from its storage hanger. Unscrew the plug and hold the hose end above the water level in
the tank to avoid sudden, uncontrolled flow of dirty water. With the plug completely off, carefully direct
the water flow to the desired drain. Reinsert the plug and tighten and return to its storage hanger.
The recovery tank should be rinsed out to remove solids in the tank. Open the Cleanout cap to remove
the Stopper plug. Tilt the recovery tank (similar to accessing the batteries) and clean the sludge that has
settled in the sump area by either back flushing or by scraping it out. Be sure to tightly secure the
Stopper plug and cleanout cap before continuing to operate the scrubber.
Refill the solution tank and continue scrubbing until the job is done or when the machine runs out of
power.
The battery gauge bar icon will flash to signal the operator that the machine is almost out of power.
Once this signal is displayed to the operator, all functions will shut off (brush will turn off and the scrub
deck will raise up, water flow will cease, the rear squeegee will raise up and the vacuum motor will turn
off) including the transport mode. The machine then will only have a few minutes left of reserve power
for a short Vacuum only mode to pick up remaining solution on the floor and Transport power to drive
to the battery recharging station.
AFTER USE:
When finished scrubbing, select the Transport mode, all functions will shut off (brush will turn off and
the scrub deck will raise up, water flow will cease, the rear squeegee will raise up and the vacuum motor
will turn off). Drive the machine to a service area for daily maintenance and review items that may need
service.
Empty the solution tank, by opening the solution hose valve into a drain. Rinse the tank with clean
water to prevent any build-up of dried up chemicals that could cause clogging in the plumbing.
Empty the recovery tank as described on line 11 and 12.
Remove the brushes or pad holders and rinse them in warm water and hang to dry.
Remove the rear squeegee, rinse with warm water and reinstall after cleaning.
Check the maintenance schedule on the next page and perform any required maintenance before
storing the machine.
Store the machine indoors in a clean dry place. Keep from freezing. Leave solution and recovery tank
lids open for ventilation to prevent odor build-up.
Turn Key switch OFF (O) and remove key.
