SCV™28/32 Literature and Fact Sheet
1
General Overview
The SCV®28/32 is a powerful and compact rider scrubber. Maneuvering through tight
spaces with ease, the SCV®28/32 scrubs a 28 or 32-inch path with disc or cylindrical
brush heads, cleaning 40,500 to 44,000 sq. feet per hour, while the operator rides in
complete comfort.
2
Construction
The SCV®28/32 is constructed of a rotationally molded polyethylene solution/recovery
tank and a 1/8” x 2” x 4” structural steel tubing frame, which is powder paint coated, to
resist corrosion and scratching. Explain how durable the housing is, with the use of
structural steel tubing for a frame. A normal steel metal frame normally has one wall;
tubing has multiple members.
3
Battery Compartment
Open up the battery compartment and point out the six, 6-volt, 275AH batteries, that will
give the customer several hours of run time, on a single charge. Optional 370 AH batteries
are available if extra run time is needed. The batteries sit in a polyethylene battery tray to
prevent acid spills and to protect the machine.
4
Drive System
A 1.2 HP traction drive motor is mounted on the front wheel. The SCV®28/32 features a
built-in E-mag brake for automatic braking when accelerator is released. The motor also
propels the scrubber up to 4 mph in the transport mode. Explain that the front wheel is
3.5” x 12” and has a double crosshatch thread for added traction. The rear wheels are 4”
x 14” soft ride double crosshatch non-marking gray.
5
Disc Motor System
The 28" disc scrubber utilizes one 1.5 HP motor to drive the two, right-angle gear boxed
brushes. The 32" disc scrubber utilizes one 2 HP motor. The operator at the control panel
will select the down pressure of the brushes. There are two pressure settings, regular and
heavy. The brushes are 14” and 16” and they counter-rotate at 300 RPM. Use 13" and 15"
pad holders with 14" and 16" pads. The cleaning solution is center fed to the disc
brushes.
6
Easy On/Off Brushes (disc deck)
Show the easy access to the brushes, through the side skirt. Point out the side squeegee
blade and explain, how the solution is contained to the brushes and channeled to the rear
of the machine. Remove the skirt, to show the easy access to the 14” or 16” brushes.
Show the customer, how easy it is, to remove and install the brushes. Explain the various
brush options. Show how the solution is fed to the brushes, when activiated, located
behind the drive wheel; therefore keeping the drive wheel dry and non-slippery. Also
explain, that the brushes are computer controlled, in order to follow the contour of the floor.
Show that the brushes raise and lower automatically, when activated. Point out center feed
aluminum drive hubs.
7
Cylindrical Motor System
The cylindrical brush deck has two 1 HP motors to drive the brushes. The operator at the
control panel will select the down pressure of the brush. There are two pressure settings,
regular and heavy. The brushes are 28” or 32” and it rotates at 900 rpm. The cylindrical
brush deck also has five quick disconnect spray jets, uniformly dispersing cleaning
solution to the brush. In addition, the cylindrical brush deck has a wet sweeping debris
tray.
8
Easy On/Off Brushes (cylindrical deck)
Show the easy access to the brushes. Point out the side squeegee blade and explain,
how the solution is contained to the brushes and channeled to the rear of the machine.
Actually show the customer, how easy it is, to remove and install the brushes. Open the
side skirt, unscrew the three 1/4” wing nuts and take off the panel that holds the brush. You
are now ready to remove the cylindrical brush by pulling it out, to install the brush reverse
all the steps. Show, how the solution is fed to the brushes, located behind the drive wheel;
therefore keeping the drive wheel dry and non-slippery. Also explain, that the brushes are
computer controlled, in order to follow the contour of the floor. Show that the brushes raise
and lower automatically, when activated. Point out center feed aluminum drive hubs.
9
Rear Squeegee Assembly
Point out that the squeegee is a curved, swing-type assembly, which is easy to remove
from the scrubber. The squeegee on the SCV28 features 30½” of rigid blade, plus extended soft ends totaling 33" 84cm) in length. The squeegee on the SCV32 features 34½”
of rigid blade, plus extended soft ends totaling 37"(94cm) in length. The squeegee is selftracking, leaving the floor virtually dry. Remove the assembly and show the customer, that
no tools are needed. With the squeegee in hand, show the four-sided squeegee blade in
the rear and the slotted and non-slotted wiper blade in the front, for different types of floors.
Explain, how to remove the blade, rotate it and place it back on the assembly, again
without any tools. Explain the breakaway feature and how the pitch of the assembly can be
adjusted, if necessary. Explain that the squeegee will raise and lower automatically, when
activated. Point out the side squeegees which are attached to the scrubber and
channel the dirty solution to the rear squeegee, helping contain it within the
machine's cleaning path. Explain how the side squeegees raise and lower when the
scrub deck is raised and lowered.
10
Vacuum and Recovery Hose
Explain the benefit of the recovery hose and show that it can be removed, in order to clean
out clogs. Also point out that the vacuum hose is 1½” in diameter, to reduce the chance of
clogging and to allow for more airflow. Point out the 1 HP upright tangential vacuum motor
by opening the clear cap and cleaning filter at the top of the tank.
11
Recovery Tank Discharge
Explain how the 1½” discharge hose will allow for quick and easy emptying of the recovery
tank. Also point out the 6” cleanout screw-on cap that can be used to clean out debris from
the tank that has settled on the bottom. After removing all the dirty water, take off the
cleanout screw-on cap, tilt the tank back and hose out all of the dirt and debris. Remember, to remove the squeegee, so debris does not get on the squeegee assembly.
12
Operator's Compartment
Bring the customer to the operator’s compartment. Point out the 180-degree vision.
Show the adjustable, cushioned seat. Explain, that this is a safety seat that will not allow
the scrubber to move, unless the operator is seated. Then show the two -position
column adjustment for operator comfort. Explain that the SCV is equipped with redundant electronic E-Mag, plugging and dynamic braking systems. These are installed to
ensure safe stopping at all times. Show the directional switch on the operator's left side
which allows them to go into forward or reverse with the "flick" of the switch. Also show
the customer the safety horn and the key lockout switch.
13
Control Panel
Finally, show the customer the control panel. Emphasize that the panel buttons are multi-functional, yet simple to use
and understand.
1. All functions on water flow, vacuum, squeegee
and brushes set at HEAVY pressure
2. All functions on water flow, vacuum, squeegee
and brushes set at REGULAR pressure
