Operations
How This Machine Works
The Chariot® CV86 is a battery powered, selfpropelled, vacuum intended for commercial use. The
appliance vacuums debris and dirt from the floor and
collects it in the debris tray and disposable bag.
The machine's primary systems are the brush system,
vacuum system, and operator control system.
The function of the brush system is to brush the floor.
The brush system consists of two cylindrical type
brushes, brush motor, brush deck, side broom, side
broom motor and controls. The front brush turns
clockwise when viewed from the right side of the
machine. The rear brush turns counterclockwise. Both
brushes work to agitate the floor and to route the debris
up into the brush deck. The side broom rotates counterclockwise as viewed by the operator. The side broom
sweeps debris into the path of the brush deck.
The function of the vacuum system is to vacuum fine
dirt and debris into the vacuum bag, and large debris
into the debris tray. The vacuum system consists of the
debris tray, vacuum motor, vacuum filter and vacuum
bag. The debris tray captures the dirt of f the floor as the
machine moves forward. The vacuum motor provides
suction to draw the fine dirt into the vacuum bag, and
the debris tray stores large debris.
The function of the operator control system is to control
the direction and speed of the machine. The dir ectional
control system consists of the direction control drive
reset switch, throttle pedal, emergency stop switch,
steering wheel, propel controller, and drive wheel. The
directional control drive reset switch signals forward or
reverse direction and makes sure the operator is on
platform before machine will propel. The controller
interprets signals from the throttle pedal to command
the drive wheel to propel or slow the machine. The
steering wheel points the drive wheel in the direction
desired by the operator. The brake automatically
engages when the operator steps off the platform, turns
the key off, or engages the emergency stop switch.
NOTE: Impact to machine may cause damage.

Operations
Normal Vacuuming
Plan the vacuuming pattern in advance. The longest
track is around the perimeter of the area to be cleaned.
For efficient operation, the runs should be the longest
possible without turning or stopping.
In order to achieve the best possible results, the area
which is to be cleaned should be picked up before
vacuuming. Large debris, strings and wire must be
removed to prevent being caught in brushes.
NOTE: Check and empty debris tray as needed
during operation.
If machine is allowed to stand in neutral with the
vacuum deck down for more than 2 seconds, the brush
motor stops. If either forward or reverse travel is
selected, the brush motor will continue once movement
of machine begins. Overlap the brush path and avoid
transporting over previously cleaned areas.
Recommended Path
To Begin Vacuuming
When operating the machine around people, pay
close attention for unexpected movement. Use
extra caution around children.
Lorsque vous utilisez la machine en présence de
gens, portez une attention particulière aux mouvements inattendus. Soyez plus prudent, surtout en
présence d’enfants.
1. Stand on the operator platform. Throttle pe dal must
not be depressed.
2. Turn key switch to turn machine power on.
3. Check position of Directional Control Switch to
ensure that machine is set to travel in direction

Batteries (Wet Cell Only)
The batteries provide the power to operate the
machine. The batteries require regular maintenance to
keep them operating at peak efficiency.
The machine batteries will hold their charge for long
periods of time, but they can only be charged a certain
number of times. To get the greatest life from the
batteries, charge them when their charge level reaches
25% of a full charge. Use a hydrometer to check the
charge level.
Do not allow the batteries to remain in a discharged
condition for any length of time. Never expose a
discharged battery to temperatures below freezing.
Discharged batteries will freeze causing cracked
cases. Do not operate the machine if the batteries are
in poor condition or if they have a charge level below
25% (specific gravity below 1.155).
Keep all metallic objects off the top of the batteries, as
they may cause a short circuit. Replace worn or
damaged cables and terminals.
Check the electrolyte level in each battery cell before
and after charging the batteries. Never add ac id to the
batteries, use distilled water. Do not allow water level to
fall below the battery plates. Portions of plates exposed
to air will be destroyed. Do not overfill. Keep plugs
firmly in place at all times.
Maintenance
Wear eye protection and protective clothing when
working with batteries.
Portez des lunettes de protection et des vêtements
de protection lorsque vous travaillez avec des
batteries.
Charge batteries in a well ventilated area.
Chargez les batteries dans un endroit bien ventilé.
Battery Maintenance
1. When cleaning the batteries, use a solution of
baking soda and water. Do not allow the cleaning
fluid to enter the battery cells, electrolyte will be
neutralized.
2. Maintain the proper electrolyte level in each battery
cell. If a cell should accidentally overflow, clean
immediately.
3. Wipe off the top of the batteries at least once a
week.
When servicing machine, avoid contact with
battery acid.
Lors de l'entretien de la machine, évitez tout
contact avec l'acide de batterie.
Batteries emit hydrogen gas. Explosion or fire can
result. Keep sparks and open flame away. Keep
covers open when charging.
Les batteries émettent du gaz hydrogène. Une
explosion ou un incendie peu t en résu lt er.
Maintenez les étincelles et les flammes nues à
l’écart. Gardez les carters ouverts lors du chargement.
4. Test battery condition with a hydrometer at least
once a week.
5. Ensure that all connections are tight and all
corrosion is removed.
Every 4 to 6 months, remove the batteries from the
machine and clean the battery cases and battery
compartment.
