INSPECTION
Carefully unpack and inspect your CP Walk-Behind Scrubber for shipping damage. Follow
unpacking instructions on shipping pallet. Each unit has been tested and thoroughly inspected
before shipment. Any damage is the responsibility of the delivery carrier who should be
notified immediately.
ELECTRICAL
This machine is battery operated and designed to operate on 36 volts DC (6) 6-volt batteries.
BATTERIES
The recommended batteries are rated 275Ah (Minuteman P/N 956740).
We do not recommend mixing AMP hour capacities. Any alternate battery sets can be used if
they equal physical size and capacity. See page 13 for service and installation.
OPERATOR RESPONSIBILITY
Read this manual carefully before operating this machine.
The operator is responsible in taking care of the daily maintenance and check ups of the
machine to keep it in good working condition. The operator must inform the service mechanic
or supervisor when the scheduled maintenance intervals are required as stated in the
MAINTENANCE section of this manual.
Before starting familiarize yourself with the machine and its controls (see “Machine Overview,
Front”, “Machine Overview, Rear”, “Operator Compartment”, “Control Console”
diagrams).

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.

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.
