position
Tangling up Risks due to wearing inappropriate
working clothes
Training Risks due to lack of operational training
NOTE: In order to reduce all consequences of the above-
mentioned risks, we advise that machine operators will
follow the instructions in the manual at all times.
PROPANE SAFETY
Propane is a flammable gas whose vapors are
heavier than air. As is the case with gasoline, propane can
explode if the proper cautions are not heeded. Propane is
odorized with an agent having a distinct odor that is
recognizable at very low concentrations. This helps in
identifying leaks, even when they are small.
Awareness and basic safety precautions are
required when working with propane. As long as these
precautions are followed, risk is negligible. Ignorance,
however, could pose needless risk.
The two greatest hazards with propane powered
floor care machines are:
- Carbon Monoxide Poisoning: This is the most
frequently reported incident associated with propane
powered floor care machines and is caused by excessive
exhaust emissions. The symptoms are headache,
dizziness and nausea. A major cause involves engines
with poor preventive maintenance practices, usually those
with dirty air filters and machines operated in confined
areas without adequate ventilation. Another cause may be
substandard, inexpensive machines with no emissions
control technology and improperly set carburetion.
- Overfilled Fuel Cylinders: Nearly all fire related
incidents reported result from bringing a cylinder into a
building without first checking for overfill. This action is
dangerous, unwise, and unnecessary.
FIRE SAFETY
Be aware of the potential dangers of fire or
explosion when using propane, and take normal fire-safety
precautions.
Fire: There is a possibility of fire from LPG vapor leaking
or venting from fuel cylinders or carburetion equipment.
Explosion: LPG vapor concentrated or confined to a
small, restricted space may explode or ignite.
Propane may experience a BLEVE, a boiling liquid
expanding vapor explosion.
EMISSIONS
All propane powered floor care machines produce
emissions. Most are harmless, but some are dangerous
and can be fatal. Carbon monoxide (CO) poses the
greatest risk, since CO can be lethal within as little as 30
minutes exposure at 3,000 parts per million (ppm)
concentration.
Carbon monoxide is an invisible, odorless,
colorless gas created when fossil fuels (such as gasoline,
wood, coal, propane, oil and methane) burn incompletely.

Superabrasive Owner’s Manual Original Language –Lavina ®32G-X/GTX 7/2019

HAZARD COMMUNICATION
A Material Safety Data Sheet for propane
shall be posted in all buildings where propane
will be used.
Because propane is odorized, it is easily detected at
levels of just a few parts per million, which is much less
than the exposure limit of 1000 parts per million.
If you smell propane while operating a propane floor
care machine, do the following:
Stop the engine:
1. Pull the throttle to the stop position (if present) or
turn the key switch to the off position.
2. Shut off the service valve on the propane
cylinder.
3. Move the floor machine to a well-ventilated area.
4. Remove the cylinder from the machine and take it
outside the building.
5. If the cylinder is leaking, contact a DOT approved
repair shop to determine the cause of the leak
and have the shop, not you, repair it.
If a fire occurs while the machine is being operated,
do the following:
1. Stop the engine: pull the throttle to the stop
position (if present) or turn the key switch to the
off position.
2. Shut off the service valve on the propane cylinder
if possible. Be careful not to be burned.
3. Move the machine outside if possible. If not
possible, move it to a well-ventilated area away
from flammable materials.
4. Do not attempt to extinguish the flame from a gas
leak. If you do, the gas will build up in the area
and could re-ignite. Starve the fire by shutting off
the supply of gas.
5. Have the machine and cylinder inspected before
using them again.
LOCAL AGENCIES AND
REGULATIONS
NFPA
Operating a propane powered floor care machine
requires compliance with certain safety regulations. The
National Fire Protection Agency (NFPA) Standard for
Storage and Handling of LP Gas is the appropriate
authority for safe propane use. A copy of this publication
is available through the NPFA in Quincy, MA (1-800-334-
3555).
Among its regulations, NFPA #58 requires that all
personnel employed in the handling of propane gas be
trained in its proper handling and operating procedures. It
also requires them to carry a written certification from
their employer or training supervisor to attest to such
training. Although this is directed mainly to those who fill
and transport liquid propane gas, Onyx Environmental
Solutions recommends that operators of propane
powered floor care machines in public places be trained
and certified as well.
With regard to operation of propane powered floor care
equipment, even though NFPA 58 8-4.5 says “these
machines shall be permitted to be used in buildings
frequented by the public, including the times when such
buildings are occupied by the public,” Onyx
Environmental Solutions suggests usage when occupancy
of a given work area is minimal.
CARB / EPA
The California Air Resource Board (CARB) and
Environmental Protection Agency (EPA) also set limits for
propane-powered engines used outdoors, but CARB/EPA
approval does not signify that the engine is safe to use
indoors.
CGA
The Canadian Gas Association (CGA) has set a limit of
1500 ppm CO in exhaust flow.
OSHA
For propane powered machines used indoors, the
Occupational Health and Safety Administration (OSHA)
has established a limit of 50 ppm CO for 8-hour time
weighted average (TWA) in ambient air and is considering
a limit of 800 ppm CO in exhaust flow.
DOT
The Department of Transportation (DOT) has established
regulations regarding the safety of fuel cylinders including
the ones used on propane powered floor care machines.
Local Agencies
Local law enforcement agencies such as the local Fire
Marshall also rely on independent testing labs such as UL
and CGA before giving their approval of the use of some
equipment. These labs thoroughly test equipment and
submit their stamp of approval only after rigorous testing.
While not being required by all law enforcement agencies,
the stamp of approval by these agencies further assures
the operator that he or she is working with and around
safe equipment.
NOTE: In order to reduce all consequences of the above-
mentioned risks, we advise that machine operators will
follow the instructions in the manual at all times.
RESIDUAL RISKS
During the normal operating and maintenance cycles, the
operator is exposed to few residual risks, which cannot be
eliminated due to the nature of the operations.
BEFORE YOU BEGIN
Working area must be clear from any debris or objects.
A first-time operator must always read the manual and pay
attention to all safety instructions.
All propane connections and cables must be inspected for
potential damages.
Ground wire system of the power supply must be also
inspected.
Perform general daily inspections of the machine and
inspect the machine before each use.
Always inspect the safety devices:
The emergency break must be clear and working
The tool protector must be working
The machine must be clean
Never operate the machine in the rain!
Confirm that there are no missing parts especially after
transportation, repair or maintenance.
Before filling the water tank with water make sure the
machine is not working and the main switch is turned off.
Before turning on the machine make sure that the base is
placed on the floor, the machine MUST NOT be in an
upright position when turned on!

Superabrasive Owner’s Manual Original Language –Lavina ®32G-X/GTX 7/2019

OPERATING MACHINE
Never work with the machine without visual contact with
it.
Never run the machine when you are situated between
the handles of the wheel
When operating the Lavina®32G-X, make certain that
there is no one, but you around the machine.
Never leave the machine unattended while working.
The water hose must move freely and must be damage-
free.
Check if the floor, you work on, is not too uneven. If this is
the case, it may damage the machine.
AFTER WORK IS COMPLETED
Clean the machine and its surroundings properly
Empty and clean the water tank
Store the machine in a safe place
Place the Propane bottle outside in its storage
THE WORK AREA
Make certain that people or vehicles do not enter the
work area.
Avoid cables and hoses being in the way.
Always check the floor for debris
PERSONAL PROTECTIVE
EQUIPMENT (PPE)
Always wear safety shoes when working with the
machine.
All personnel in the immediate work area must wear
safety glasses with side shields.
Always wear safety gloves when changing the tools.
Always wear clothes suitable for the work environment.
Always wear Carbon Monoxide Indicator badges as an
extra precaution.
The plastic indicator contains a colored indicator button
that darkens in the presence of Carbon Monoxide. The
relative darkness of the indicator button indicates the
level of CO in the ambient atmosphere. Most indicator
badges have a useful life of 30 days, depending on the
concentration of contaminants, humidity, and
temperature.
TESTING
There are a great number of instruments offered
on the market to test for toxic gases. Only those designed
to read carbon monoxide resulting from combustion
engines is considered acceptable for testing exhaust
emissions from propane powered floor machines.
Some instruments are used to read “ambient air”
and may be damaged if used to take readings in the
muffler or tail pipe. Selecting the proper instrument is an
important part of meeting the testing requirements.
Generally speaking, units capable of reading in
ppm, (parts per million), at ranges from 0 to 1000 are
adequate for checking ambient air (air in the breathing
zone of the operator). Instruments capable of testing
carbon monoxide in the exhaust should be able to read
from 0 to at least 2000 ppm and should be certified by the
manufacturer for that purpose.
Some instruments and systems used for these
purposes are:
1) AMBIENT AIR MONITORING
DRAGER Model 190: Manufactured by National
Drager.
SENSIDYNE gas sampling system with YB-11038
Sensidyne dectector tubes
DRAGER gas sampling system with YB-4620

BIOSYSTEMS INC. “TEXILOG” Data-Logger
All instruments used for testing must be calibrated at
intervals recommended by the manufacturer. The
monitor, model number and date of calibration will be
recorded with all test results.
OPERATOR
The operator Lavina®32G-X machine must have an
adequate technical knowledge and preparation.
The operator must know the machine’s work environment.
Only one operator at a time can work with the machine.
The operator must be properly trained and well instructed
prior operating the machine.
The operator must understand all the instructions in this
manual.
The operator must understand and interpret all the
drawings and designs in manual.
The operator must know all sanitation and safety
regulations pertaining to the operation of
The operator must have floor grinding experience.
The operator must know what to do in case of emergency
The operator is expected to operate their equipment safely
and responsibly. They are responsible for the proper
handling and storage of propane cylinders, identifying
potential hazards associated with his job and avoiding
these hazards at all times.
PROPANE CYLINDERS
The Propane cylinders are constructed of either
aluminum or steel. We recommend aluminum because it
is lighter and guards against rusting. The cylinder used on
propane powered floor machines is classified as a 4E240
cylinder. Its rated capacity is 33.5 lbs. and this designation
refers to the model of the cylinder. Actual propane
capacity achieved during filling can be less than, equal to,
or slightly more than 33.5 lbs. Use only UL, CTC/DOT
listed cylinders.
The propane cylinder used on the floor machine is
a motor fuel cylinder as listed by the Department of
Transportation. Unlike the common 33.5-lb propane
outdoor grill cylinders (which are not legal for use on
propane floor machines), the motor fuel cylinder has a
number of safety systems designed into it to ensure your
safety at all times.
There are two types of 33.5 lb. motor fuel
cylinders.

vehicles like forklifts. These machines have special
vaporizing carburetors to allow the propane to change
from a liquid to a gas before being burned in the
combustion chamber.
The vapor draw cylinder is used on small
machines like the propane powered floor care machines.
The vacuum generated by the engine draws up the
Propane gas vapor through the fuel system. The propane
powered floor care machine does not have an
evaporating system and will freeze up if liquid propane is
introduced to it. It is necessary that special attention be
paid to ensure that neither the liquid nor the vapor draw
cylinders be overfilled.
REFUELLING CYLINDERS
The proper filling of propane cylinders is a subject
so important that it warrants special attention. Propane
cylinders should only be filled by qualified propane
dealers.
Most important, propane cylinders should be filled
no more than 80% of their rated capacity. The other 20%
is called the vapor space or headspace. This vapor can
be compressed without causing the pressure relief valve
to open and vent gas to the area around the cylinder. If
there is no headspace to allow for fuel expansion, the
pressure relief valve will open, releasing propane gas into
the atmosphere. This is a very dangerous and volatile
situation as there is always the possibility that enough of
the vented gas could find its way down to the floor and
come in contact with a pilot light from a furnace, hot water
heater, or other source of ignition. Propane changes into
a gas, is -44º F (-42º C). Exposing unprotected skin to
propane gas or liquid could result in frostbite injury.
All new cylinders should be vented and purged of
air per manufacturer’s instructions before use. Never
bleed propane cylinders indoors.
STORAGE CYLINDERS
When not in use, propane cylinders always
should be stored outside in an upright position in a
secure, tamperproof, steel mesh storage cabinet. This
cabinet may be located next to the building but with at
least five feet (1.5 m) of space between the cabinet and
the nearest building opening (door or window), also away
from heat and direct sunlight.
Do not install the cabinet near a stairway or street
elevator as vented propane gas will seek a lower level
since it is heavier than air and could find its way into the
basement of the building. Do not store cylinders full or
empty inside a building or inside a vehicle. Although it is
unlikely that propane will vent from a stored cylinder, if it
should, the vapor could come in contact with an ignition
source such as a spark from a power tool or other
appliance and create a flash fire.
Do not smoke or use a device with an open flame
when handling or transporting propane cylinders.
TRANSPORTING CYLINDERS
When transporting cylinders to a propane dealer
or to a job, make sure the cylinders are securely fastened
and standing in an upright position with the service valve
closed.
A cylinder rattling around in the back of a vehicle
and banging into other objects constitutes a hazard. Avoid
dropping or banging cylinders against sharp objects.
The propane cylinders are sturdily constructed but
a series of hard jolts could cause damage.
Please note that any cylinder that has been filled
is always considered full, no matter how little propane gas
remains in it. This is because even when all liquid has
evaporated into vapor there is still some propane gas
vapor left in the cylinder. Because this remaining fuel is
flammable, an empty cylinder should be treated with the
same careful procedures as one that is filled to the 80%
level with liquid propane. The only time that a cylinder is
considered empty is when it is new, before it has been
filled with propane.
When transporting a propane powered floor
machine, the propane cylinder may be strapped onto the
machine as long as the machine itself is firmly secured in
the vehicle.
Of course, spare cylinders should always be secured in an
upright position

4. OPERATION
PRELIMINARY CONTROLS
Inspect the working area as explained in the safety instructions. For wet use, fill in the water tank. Connect the vacuum
extractor and ensure that the vacuum hose is clear and it will follow the machine easily.
CONTROL OF THE WATERFLOW
Using the valve (Fig.4.2-2) the operator can choose from where the water will spray:
- when the handle of the tap is in vertical position the water will spray in front of the machine (fig.4.1),
- when the handle is in the horizontal position the water will spray under the cover of the machine.
The flow regulating valve located on the tank (Fig.4.3) is increasing or reducing the waterflow to the working area –in
front of the machine or under the main head cover of the machine.
The valves (Fig. 4.2-1 and Fig. 4.2-3) are controlling the flow of an external water supply. A ¾” water tube can be
attached to the quick connection (Fig. 4.2-4).

ADJUSTING AND MOUNTING TOOLS
The Holder A41 in the LAVINA® X can work with either 3 or 6 rubber buffers, which
will alter its elasticity (3
will be more flexible
than 6). You can make
the change after
dismounting the holder
as per the instructions
in
TROUBLESHOOTING.
In the Lavina 32G-X,
the holder is initially
mounted with 6
buffers.
Mount the tools only after ensuring that there is enough diamond bond material left. Be sure that the plates are always
clean before mounting.
WARNING: Always Secure the Quick Change tools with the security plate (Fig.4.5 in red), lock with the tool
holder key (Fig.4.6) and make sure that the butterfly is securely locked at 90 degrees. Diamond tools with
Velcro are attached on six foam plates (9 inch).The foam plates are mounted on the key lock (butterfly). Always
use the tool holder key (Fig.5.1).
The machine can work with 3 operating heads by operating every other head as shown in Fig.4.7. For the inactive
heads, remove the holders only (not adaptors), and screw the bolts mounting the holders into the free thread holes of
the adaptors in order to protect them.(Fig.4.7)
ALARM
EnviroGard employs a sensor (Fig. 4.6) in the exhaust path between the engine and the
catalytic muffler to detect the oxygen content of the exhaust before it is passed through the
catalyst. The oxygen sensor does not react to nor does it measure the CO content of the
exhaust. It responds only to oxygen content.
The Control Module is set to ignore the readings from the oxygen sensor during the first three
minutes
the engine is running. This period allows: The sensor to reach a stable operating temperature.
The catalyst in the muffler to reach the temperature necessary to reduce the levels of CO,
nitrogen oxides (NOx) and hydrocarbons (HC) in the exhaust.
The most common event in which the Control Module shuts down an engine is when the air filter becomes dirty enough to restrict
the air intake flow, which changes the air-fuel ratio such that the oxygen sensor signal is outside the control limits. Once the air
filter is properly cleaned, operation of the machine can be resumed.

FUEL-MINDER USER MANUAL
The SM40 Fuel-Minder is a high-performance, digital fuel control system featuring closed loop feedback, fuel lock-off capability, emissions safety
warnings with shutdown, and an LCD screen for user interface. The system is highly responsive to changes in engine load, providing optimum the air-
to-fuel ratio regardless of operating conditions.
SYSTEM COMPONENTS
The following parts are included with the system
Electronics Module
Integrated Wire Harness
Fuel Control Valve
Fuel Control Housing
O2 Sensor
LPG Regulator with lock-off
*Individual items are available as replacement parts if necessary*
OVERVIEW OF FEATURES
Closed Loop Fuel Management System
The Fuel-Minder uses closed-loop feedback from the O2 sensor to control the amount of fuel introduced to the engine
via the Fuel Control Valve. This technology continuously monitors engine emissions and is capable of making fuel
corrections to compensate for varying engine loads and conditions.
Faulty O2 Sensor Detection
If a faulty O2 sensor is detected, the Fuel-Minder will alert the user within 3-5 minutes from a cold-start. A message will
be displayed on the LCD screen to let the user know that the O2 sensor needs to be replaced.
Built-in Fuel Lockoff Controller
The Fuel-Minder also controls the fuel lockoff and only allows fuel to pass through if it detects the engine is cranking.
Once the Fuel-Minder is powered off from the equipment key switch, the Fuel-Minder closes the fuel lockoff and shuts
the engine down immediately.
Emissions Warnings and Shutdown
If the Fuel-Minder detects engine emissions that are too lean or rich for a period of 5 minutes, it will shut the engine
down via the fuel lockoff. The Red LED will blink and the LCD will display a message alerting the user of the issue and
will prompt some common fix suggestions.
Dual Hour Meters
The Fuel-Minder has two hour meters, one for the engine and the other for equipment. The Engine Hours are resettable, which should only be done if
the engine is replaced. The Equipment Hours (located in Options Menu) is non-resettable and shows the total hours on the equipment, similar to the
odometer of a vehicle.
Battery Voltmeter
This feature allows for real-time display of the battery’s voltage, which also helps for troubleshooting any battery or
charging system issues that may arise.
Engine Tachometer
Displays the current engine speed (in RPM). This should be used to assess proper idle, WOT and engine speed for the
appropriate tooling.
Job Timer
The job timer feature works when it is activated and while the engine is running, and will not continue to run if the engine
is stopped. The allows for easy timing of jobs or work areas to help determine speed.
Password Protection
Located in the options menu, the password feature allows a maintenance manager or owner to enable a password that
prevents the user from resetting the Service Due alerts without the appropriate pin.

FCC Part 15.21
Any changes or modifications to this device that are not expressly approved by the manufacturer may void the user’s
authority to operate the device.
STARTING THE MACHINE
First, follow the directions in the chapter on Safety Devices and Safety Instructions. Check oil level. Open the service
valve on the propane tank about one and a half (counterclockwise) turns. Next, make sure the Start/Stop Clutch rocker
(2) is in stop position and check that the throttle (3) in the IDLE position. This creates the necessary vacuum to open
the lock‐off valve inside the regulator. Actuation of the throttle lever will keep the lock‐off valve from opening and the
engine from getting fuel so the engine will not start. Proper maintenance will insure easy starting. Engage starter (1)
for a MAXIMUM of 5 to 6 seconds or until the engine fires. Serious starter damage will result if this is exceeded and
the warranty may not apply. Operate the engine at half throttle for approximately two minutes to properly warm engine.
Then advance to full throttle for best results. If working wet, add water to the floor surface. If working dry, instead
switch on the vacuum unit. Finally, hold the machine firmly and push the start of the Start/Stop clutch button (2).
OPERATING THE MACHINE
Guide the machine in straight lines across the floor, slightly overlapping the previously completed surface with each new
line. Work at a constant speed, allowing the tools time to work at a speed appropriate for the tools’ grit size. Avoid
vibrations. Do not stop the machine while tools are still running as they will mark the surface of the floor. When working
wet, select the destination of the water feed with the water tap (fig. 4.2-1) and periodically run the pump (fig. 4.10-11) to
release water onto the floor surface. Starting the pump is possible only if the machine motor is on. When working dry,
check the floor surface periodically for dust accumulation. Check regularly to see if your vacuum works properly.
STOPPING THE MACHINE
The stopping of the machine must be done gradually until the motor stops. Do not stop moving the machine before
the motor comes to rest, as the tools could damage the surface. To stop, push the Stop clutch rocker (2), then close
(clockwise) the service valve on the propane tank. ALWAYS allow the engine to run until it stops from lack of fuel.
•In case of emergency ONLY press the "stop" position on the Start/Stop Engine switch (1) and disconnect the fuel
line from the tank.
When finished with the machine, store the propane tank outside the building, in a SECURE place away from heat
or direct sunlight.
