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.
HAZARD COMMUNICATION
A Material Safety Data Sheet for propane
shall be posted in all buildings where propane
will be used.

Superabrasive User Manual Original Language Lavina® 3213GEB 3/2022
8
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!
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®32GE, make certain that
there is no one, but you around the machine.
Never leave the machine unattended while working.

Superabrasive User Manual Original Language Lavina® 3213GEB 3/2022

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

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.
Liquid draw
Vapor draw
The liquid draw cylinder is used on larger 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

Superabrasive User Manual Original Language Lavina® 3213GEB 3/2022
10
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
3. HANDLING AND TRANSPORTATION

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.
SERVICE ALERTS
The Fuel-Minder also provides equipment-specific service alerts for the following items:
Air Filter
Oil Change + Filter
Spark Plugs
Seal Replacements
Chain Inspections
Belt Inspections
Tooling Inspections
Each item has individual alerts at different hour intervals, and the Fuel-Minder will start alerting the user of upcoming
maintenance within 3 hours of when it is due. To reset a particular service alert, simply scroll to it, using the +or -buttons,
then hold the reset button for 2 seconds. The meter will then prompt you to reset that interval.

4.6 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).
4.7 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.
4.8 STOPPING THE MACHINE
The stopping of the machine must be done gradually until the tools mouvement stops. Do not stop moving the
machine before the tools comes to rest, as the tools could damage the surface. Stopping of the machine must be done
gradually.To begin, disengage the clutch by pushing the Stop clutch rocker (2), and return the throttle (1) to the
IDLE position. Wait 5-10 seconds. Turn the Start/Stop Engine switch (5) fully to the left in order to arrest the
engine.Close (clockwise) the service valve on the propane tank.
•In case of an emergency ONLY press the “Emergency Stop Button" (1).
When finished with the machine, store the propane tank outside the building, in a SECURE place away from heat or
direct sunlight.

Tampering w/Emission Control System Prohibited
Federal law and California State law prohibits the following acts or the causing thereof: (1) the removal or rendering
inoperative by any person other than far purposes of maintenance, repair, or replacement, of any device or element at
design incorporated into any new engine for the purpose of emission control prior to its sale or delivery to the ultimate
purchaser or while it is in use, or (2) the use of the engine after such device or element of design has been removed or
rendered inoperative by any person.
Among those acts presumed to constitute tampering, involve the parts/systems listed below:
Carburetor and internal parts
Spark plugs
Magneto or electronic ignition system
Fuel filter element
Air cleaner elements
Crankcase
Cylinder heads
Breather chamber and internal parts
Intake pipe and tu
CLEANING
Keep your machine clean. Cleaning the machine on a regular basis will help detect and solve potential problems before
they cause damage to the machine. Most importantly, check and clean the tool plate connections, power cord and plugs,
vacuum hoses and water tank.
CHECK DAILY After operating the Lavina® 32GE, the operator should conduct a visual inspection of
the machine. Any defect should be solved immediately. Pay attention to power cords, plugs
and vacuum hoses loose bolts or screws.
Tool holders: Buffers and elastic element are consumables and must be visually checked
daily and replaced if needed. The key lock holders (butterflies) on the tool holders should be
also checked.
Check the rubber buffers and make sure the holders are secure. The flange holding
the buffers (Fig.7.1-1) has to be firmly secured to the unit. A gap seen here indicates loose
screws securing the holder. The screws have to be tightened immediately to safely operate
the machine. Working with loose screws could cause serious damage to the machine. The
tightening force on the screws should be 22-25N.m (16-18lbf.ft).
It is very important to regularly check the screws that secure the “QuickChange” holder to the
safety part (Fig.7.1- 2), so that the holder will not fly away if the buffers get damaged. The
“QuickChange” should also be cleaned.
CHECK AND REPLACE AFTER THE FIRST 8 WORKING HOURS
Replace the oil in the engine after the first 8 hours work, according to the instructions of the engine manufacturer.
Always use 30HD or 10W30 engine oil with all of the following ratings: SF, SG, and CC
CHECK AND REPLACE EVERY 50 WORKING HOURS
Change engine oil, while changing check for leakage of engine oil at the various seals. The hour meter will blink between
48-52 hours as a reminder /"Engine Oil Capacity" is 1.7L(1.8US.qt) when oil filter is not removed; 1.9L(2.0US.qt) when oil
filter is removed/.
RECOMMENDED OIL CHANGE INTERVALS
Do not exceed the 50-hour oil change interval. Oil changes more frequent than 25 hours will give even longer engine life.
In any case, always use 30HD or 10W30 engine oil with all of the following ratings: SF, SG, and CC. make sure the oil
level is maintained at the "FULL" level.
CHECK EVERY 200 WORKING HOURS
Every 200 working hours, the operator should inspect all parts of the machine carefully. Most importantly, inspect and
clean the tool plate connections, plugs, vacuum hoses and water tank and filter. Also, check the water flow of the pump.
Check the guard assembly. Make certain the wheels are clean and rotate properly. Inspect the control buttons. If there are
defective control parts, they should be replaced immediately. Replace worn vacuum- and water hoses.
Carefully inspect the seal rings and bearings of the grinding units, and replace any showing signs of excessive wear.
For more information, refer to chapter troubleshooting below. Open the service cover on the motor base Figure 9.7.2 to
