SAFE USE
The LAVINA® 25GEB is designed to reduce all risks correlated with
its use. However, it is not possible to fully eliminate the risks of an
accident with the machine. Unskilled
or uninstructed operator may cause correlated residual risks.
Such risks are:
- Position Risks due to operator’s incorrect working position
- Entanglement Risks due to wearing inappropriate working
clothes
- Training Risks due to lack of operational training
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®25GEB 1/2021
9
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
Clear working area of 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.
 Perform general daily inspections of the machine and
inspect the machine before each use.
 Always inspect the safety devices:
 The tool protector must be working
 Mount the security disc when working with Quickchange Pads.
 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 running 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 a tilted
position when starting
OPERATING MACHINE
When operating the Lavina® 25GEB, 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.

Superabrasive User Manual Original Language Lavina®25GEB 1/2021
10
 Make sure the working surface is not too uneven. If it
is, 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 designated storage
The Work Area
Prevent people or vehicles from entering the work area.
Clear all hoses and cables from the work area .
Always check the floor for debris
PERSONAL PROTECTIVE EQUIPMENT
(PPE)
Always wear safety shoes when working with the machine.
 Always wear ear protectors 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 are
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 Drager

ENERAC POCKET 60
3) DATA LOGGERS
INDUSTRIAL SCIENTIFIC CORP. MODEL STX‐70
CO MONITOR, Data‐Logger
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 must know the machine’s work
environment.
Only one operator can work with the machine at a time.
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 be able to 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 must have adequate technical knowledge and
preparation.
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 20 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 20 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 20‐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 20 lb. motor fuel cylinders.
Liquid draw
Vapor draw

Superabrasive User Manual Original Language Lavina®25GEB 1/2021
11
 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 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%,
which is about 4” (10 cm) from the top of the cylinder, 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 ‐ 44oF (‐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.

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 (1) 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 (4) 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 to
release water onto the floor surface. When working dry, check the floor surface periodically for dust accumulation.
Check regularly to see if your vacuum works properly.
STOPPING THE MACHINE
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 (4)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 " (6) .
When you are finished with the machine, store the propane tank outside the building, in a SECURE place away from
heat or direct sunlight.
