2. GENERAL INFORMATION
This owner’s manual is intended for the operator of the Lavina®V32GE machine, the servicing
technician as well as for anyone involved with operating or servicing the machine. We recommend
that you read the instructions very carefully and follow them strictly. The manual includes
information about assembling, using, handling, adjusting and maintaining your Lavina®V32GE
concrete dust collector.
2.1 MANUFACTURER
Superabrasive was founded in 1987, as a manufacturer of high quality diamond tools for the
stone and concrete industry. Today, Superabrasive is one of the world’s leading companies in the
production of diamond tools and floor grinding machinery. At Superabrasive, we strive to deliver the
very best solutions to our customers, and enable them to work more efficiently.
2.2 GENERAL DESCRIPTION
Lavina® V32GE dust collector is designed for sucking and separating dry, non-combustible and
non-explosion dust. Dust laden air is sucked through at high speed via the suction hose. When the
dust engage the vacuum, it is been separated in four stages. The first one is the integrated pre-
separator, which captures around 90% of the large dust particles (the efficiency depends on the dust
particle size –the larger the better). In the next stage, the smaller dust particles that passed through
the pre-separator engage the filter chamber, where a second cyclone is formed around the filter
itself, which prevents larger dust particles to engage it. The next two stages are the main filter and
the HEPA filter. The machine is designed to clean the primary filter by impulse reverse airflow. To
discharge the dust from the vacuum’s cylinders, the following must be done:
The separated dust accumulates in the cyclone until you open the valve situated on the
vacuum’s hood or the machine is switched off. Either way the dust drops through the bottom flap
into the plastic bag.
Lavina® V32GE dust collector has two hoses:
-Main hose with Cam Lock to connect to the grinding and polishing machine;
-Accessory hose with cuff for the wand;
WARNING!
The dust collector Lavina®V32GE is manufactured and fitted for the above-mentioned applications
only! Every other use may possess risks to the persons involved.

accidents may occur if unskilled or uninstructed workers fail to heed the list of potential risks below:
• Position Risks due to operator’s incorrect working position;
• Tangling Risks due to wearing inappropriate working clothes;
• Training Risks due to lack of operational training;
NOTE: Machine operators should follow the instructions in the manual at all times.
RESIDUAL RISKS During normal operating and maintenance cycles, the operator is exposed to some.
5.6 BEFORE YOU BEGIN
• The working area must be clear from any debris or objects.
• A first-time operator must always read the manual and heed all safety instructions.
• Perform general daily inspections of the vacuum and inspect the vacuum before each use for any
sign of damage.
• Inspect all safety devices.
• The vacuum filters must be clean and the hose should be connected.
5.7 OPERATING THE VACUUM
When operating the LAVINA® V32GE, be sure that no one else is within close proximity to the
vacuum. Never leave the vacuum unattended while working. The hose must move freely, be
damage-free, and should never run beneath the vacuum or machine. Check the floor prior to
beginning any work, and ensure that it’s not too uneven, which can cause damage to the vacuum.
5.8 AFTER WORK IS COMPLETED
When work is complete, clean the vacuum and its surroundings sufficiently, empty all dust / debris,
secure the hose, and store the vacuum in a safe and secure place.
5.9 THE WORK AREA

5.10 PERSONAL PROTECTIVE EQUIPMENT (PPE)
When operating the machine, always wear safety shoes, ear protectors, safety gloves (especially
when changing tools), and suitable clothing. All persons within the immediate working area must
wear safety glasses with side shields.
5.11 OPERATOR
The operator must be aware of the vacuum’s work environment, be properly trained prior to
operating the equipment, and fully understand this manual. Only one operator may work with the
machine at a single time. The operator must understand and interpret all the drawings and designs in
manual, understand all sanitation and safety regulations pertaining to its operation, have floor
grinding experience, know how to perform in an emergency situation, and have an adequate
technical knowledge.
• The dust collector should only be operated in environments with a temperature between 41°F and
113°F (5°C to 45°C) and a maximum relative humidity of 70%.
• The work environment for the vacuum should be clean, well-lit, and free of combustible elements.
• The dust collector should not be operated without the proper filters installed. This could possibly
result in damage to the machine, and cause harm to surrounding personnel.
• Do not open the waste container or motor head assembly while the vacuum is operating.
• Do not vacuum any flammable materials or substances such as fuels, solvents, etc. A dust collector
must be specifically designed and labeled for such operation. When grinding epoxy, first ensure that
the epoxy is non-toxic.
• Do not vacuum any corrosive substances unless the vacuum is specifically outfitted with containers
suitable for this purpose.
• Do not vacuum any burning, smoldering, or hot materials. This could result in a possible explosion
and/or damage to the vacuum components.
• If toxic or harmful substances accidentally enter the vacuum cleaner, the container and filters must
be removed and cleaned immediately using the proper protective equipment and safety procedures.
• Utilize the locking caster wheel to prevent movement while work is being performed.
• When moving the dust collector, never pull on the vacuum hose. For this purpose, always use the
designated handles mounted on the machine.
• For this specific dust collector, sound tests indicate that the emitted noise is level is measured at a
maximum of 75 decibels (dBA), for a distance of 1 meter from the machine (and height of 1.60
meters). The vibrations emitted from the machine have been measured at a maximum value of 2.5
m/s2. • CAUTION: The National Institute for Occupational Safety and Health (NIOSH) recommends
that exposure to noise in the working environment be maintained below a level equivalent to 85 dBA
for a period of eight hours, in order to minimize occupational, noise induced hearing loss. Any
persons working in proximity of the vacuum cleaner should wear the proper hearing protection in
order to prevent hearing loss. Please refer to your local laws and regulations for further information
on the matter.
• When storing the vacuum, the filter should be removed and cleaned, and the waste container
should be emptied of debris. Store the vacuum in temperatures between 32°F and 104°F (0°C and
40°C). Cover the vacuum in order to protect it from accumulating debris and/ or environmental
elements.

5.12 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.
5.13 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
SAFETY PRECAUTIONS, Continued 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 a concentration of 3, 000 parts per million (ppm)
concentration.
5.14 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

Superabrasive Owner’s manual original language –Lavina® V32GE 05/2022
14
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.
5.15 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 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
 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.

5.15.1 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 nomore 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.
5.15.2 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.
5.15.3 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.

6. UNPACKING, HANDLING, TRANSPORTATION AND
STORAGE
When unpacking the machine, please check that the following accessories are included:
-Steel wand;
-Floor brush;
-Main vacuum hose with camlock to connect to the machine;
-Accessory vacuum hose with cuff to connect to the wand;
If any of the above-mentioned parts are missing, please contact your local distributor or our sales
representative. Protect the environment: Please dispose of packaging materials and used machine
components in an environmentally safe way according to local disposal regulations.
Attention
• During transportation, battery and propane tank must be securely fastened and completely
disconnected at all times.
• Before operating the vacuum after transportation, propane tank and battery must be re-connected
and correctly assembled:
- Battery: Make sure that the wires are firmly connected to the correct terminals (black (-) & Red (+).
Also confirm that the bracket that holds the battery in place is correctly assembled, so that the
battery can’t move during operation.
- Propane tank: Make sure that the tank is firmly held in place by the lock and holder plate where the
propane tank sits on the back of the dust collector. It should not be able to move when itscorrectly
assembled.
When handling and transporting the machine, never use the handles or other machine parts to lift
the machine. Use always a skid or pallet for transportation, and never transport an unprotected
machine in the rain or snow. Always store and transport the machine in an upright position. The
machine should also always be stored in a dry, frost-proof environment.

7. OPERATING WITH THE VACUUM
IMPORTANT: Before starting the machine, check the service table for daily maintenance.
Make sure that the flexible vacuum hose is securely attached to the vacuum pipe union and vacuum
cleaner inlet. Check oil level. Open the service valve on the propane tank about one and a half turns
(counterclockwise).
WARNING: 1. TURN THROTTLE TO THE IDLE POSITION;
2. START MOTOR /the engine is started by the key switch/ AND RUN ON LOWEST RPM;
3. TURN THROTTLE TO THE FULL POSITION;
NEVER START THE ENGINE AT HIGH RPM
Before use, the operator must be trained in the handling of the dust collector and the
hazardous dust.
IMPORTANT:
TO TURN OFF VACUUM: 1. TURN THROTTLE TO THE IDLE POSITION.
2. TURN OFF KEY SWITCH.
3. CLOSE SERVICE VALVE ON PROPANE TANK.
7.1 LOCKING CASTER WHEEL
There are two locking caster wheels located on the front of the
dust collector. Locking the wheel will prevent the vacuum from
moving, and possibly causing damage or injury. The wheel should be
locked on uneven surfaces to prevent unexpected rolling or movement.
To lock or unlock the caster wheel, follow the procedure shown below.
• To lock the caster wheel, press down on the metal tab.
• To unlock the caster wheel, press backwards the metal tab
protruding from the top of the wheel assembly.

7.2 MAIN FILTER CLEANING
7.2.1 MANUAL FILTER CLEANING.
IMPORTANT: Lavina V32GE is equipped with a signal lamp (fig 3.1 pos.10). The lamp starts
glowing red as the vacuum reaches the red area of the vacuum’s pressure gauge (about -
0.2bar) to indicate that the main filter must be cleaned or changed.
Lavina V32GE uses jet pulse manual filter cleaning. One cycle of filter cleaning
takes 10 to 20 seconds, depending on the vacuum’s operator. The filter must
be cleaned as the vacuum gauge goes to red (the LED lamp starts glowing) or
if there’s low suction. If the suction performance is still not improved after a
cleaning cycle is applied, the filter must be replaced with new one.
In fig. 7.2.1 you have the vacuum’s working position on the left. To clean the main filter,
follow the steps below in the exact order:
1st. Open the valve situated on the vacuum’s head cover by pushing the lever pos.1 and wait
for a few seconds before releasing. This will discharge the vacuum from the accumulated
dust.
2nd. After discharging, close the entrance valve by pushing the lever pos. 2. This creates a
vacuum in the system, indicated by the pressure gauge (fig. 3.1) as it goes to red (-0.28 to -
0.3 bar).
3rd. With the system under vacuum, open and close the valve on the head cover pushing the
lever (pos. 1) 3 to 5 times to clean the filter. Allow 1-2 seconds between each valve opening
to build up vacuum in the system again. This can also be verified via the pressure gauge.
Once complete, return to the normal operating position.

7.2.2 AUTOMATIC FILTER CLEANING.
The automatic filter cleaning triggers itself when the dust extractor reaches about -0.2bar of
vacuum, as suction becomes poor and the filter requires cleaning. It can be triggered manually by
pressing the button for ‘’FORCED CLEANING” pos.1. In some cases (depend on the tools used on the
grinding machine) before reaching -0.2 bar the dust extractor will accumulate enough dust for
several bag changes. To avoid choking the vacuum with dust before reaching -0.2bar there is a
potentiometer pos.2 with 11 positions. Each division corresponds to 5 minutes (pos.1-5min. pos.11-
55min.). This potentiometer sets the dust release interval, which lasts about 5 seconds. For example
if the dust extractor accumulates 15 kg dust in 15 minutes and the dust extractor is still far from -
0.2bar of vacuum, it needs to be discharged to prevent choking the pre-separator and maintaining its
high level of efficiency.
In case of emergency:
If the automatic system stop for some reason, there is an alternative way to clean the filter.
Remove the cotter pin pos.3 and eject the axle pos. 4. Once the actuator is detached use the axle to
rotate the inlet valve pos.6. Once the valve is closed and the system is under vacuum, rotate the axle
pos. 5 to clean the filter. Repeat the procedure with the lever 3 to 5 times and then open the valve to
its working position.
IMPORTANT: The axle pos. 5 has a hole in it with a diameter of 12mm (0.47 inch). Use a
metal rod or big screwdriver as a lever to rotate the axle.
