2. GENERAL INFORMATION
This owner’s manual is intended for the operator of the Lavina®LP36GE 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®LP36GE power trowel.
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® LP36GE ride-on power trowel is designed for the floating and finishing as well as grinding and polishing
of concrete slabs.
Read all the safety instructions carefully. Safety instructions will be found throughout this manual. Keep all
safety information in god, readable condition. Operators should be well trained on the operation and maintenance of
the trowel.
Before using your trowel, test it on a flat, watered-down section of finished concrete. This trial test run will
increase your confidence in using the trowel, and in the same time, it will familiarize you with the trowel’s controls
and indicators.
Take a notice of all the major components in point 3 like the engine, blades, air cleaner, fuel system, fuel shut-
off valve, ignition switch, etc. Ensure engine and gearboxs lubricant levels are within proper operating range.
ENGINE
This trowel is equipped with KOHLER PCV740 engine with 24HP, V-twin big block, air cooled, who work with
propane . Refer to the engine owner’s manual for specific instructions regarding engine operation.
BLADES AND FLOATING PANS
The blades of the trowel finish the concrete as they are swirled by the surface. LP36GE is equipped with two
vertical rotating shafts with with four each (6 inches wide) blades per rotor equally spaced in and attached to a
the shafts by means of a spiders. In order to use tooling for polishing and grinding, two 36-inch floating pans are
mounted on the blades. Each pan has four 13.2’’ Trowel Shine Tool Holders (metal plates with quick-change
attachment). Each trowel shine holder can be equipped with all of Superabrasive’s tools for grinding and polishing
that use quick-change connection.
HELICAL GEARBOXES
LP36GE is designed with three separate helical gearboxs assemblies

STEERING
Dual control levers located in front of the operator's seat are provided for steering this trowel. Push the left
control lever forward and pull the right control lever backward and the trowel will rotate clockwise on
approximately a center axis. Pull the left control lever backward and push the right control lever forward and the
trowel will rotate counterclockwise.
CONTINUOUSLY VARIABLE TRANSMISSION (CVT)
A Continuously Variable Transmission (CVT) has been installed to obtain maximum drive torque. This is
accomplished by continually adjusting the drive ratio to obtain optimum torque and speed during all phases of
finishing from low speed/high torque to high speed burnishing.
HOW IT WORKS
As the engine RPMs increase, the drive pulley closes, forcing the belt to ride outwards on the drive pulley.
The closing of the drive pulley also forces the belt to open the driven or secondary pulley. The opening and
closing of these pulleys creates a ratio variation—hence CVT or Continuously Variable Transmission.
WARNING!
The Lavina®LP36GE is manufactured and fitted for the above-mentioned applications only! Every other use
may possess risks to the persons involved.

• Store the Trowel in temperatures between 32°F and 104°F (0°C and 40°C). Cover the Trowel 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
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.

Superabrasive Owner’s manual original language – Lavina® LP36GE 1/2022
15
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 trowels 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 machine is a motor fuel cylinder as listed by the Department of Transportation.
Unlike the common 33.5-lbс 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 Trowel
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 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

Superabrasive Owner’s manual original language – Lavina® LP36GE 1/2022
16
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

Attention
• During transportation, battery and propane tank must be securely fastened and completely disconnected at all
times.
• Before operating the Trowel 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 machine. 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.
6.1 LIFTING THE MACHINE
IMPORTANT:
TO LIFT THE MACHINE USE ONLY THE SPECIFIED PLACES AT FIG. 6.1.

6.2 TRANSPORTING THE MACHINE
Lavina® LP36GE has a third wheel for easier transportation. It has two positions: in working position and in transport
position and is locked with a pin. To move the machine into transport or tool change position first remove the third
wheel from the working position, turn the handle of the jack to raise the left side of the machine. When you reach a
position where it is possible to place the third wheel in transport position, install it on the frame and insert the pin.
Continue turning the handle all the way, which will raise the right side of the machine and bring the machine to a
horizontal position.
To turn the machine into working condition, we perform the same actions but in reverse order.

7. OPERATING WITH THE TROWEL
7.1 STARTING THE ENGINE
Place foot on the trowel’s platform, grab on to the frame, lift yourself onto the trowel, and sit down in the
operator’s seat.
NOTICE: The trowel is equipped with a safety stop switch that will not allow the engine to start unless an
operator is sitting in the operator’s seat. The weight of the operator depress an electrical switch, which allows
the engine to start.
WARNING! –NEVER disable or disconnect the safety stop switch. It is provided for the operator’s safety, and
injury may result if it is disabled, disconnected, or improperly maintained.
NOTICE: Using the safety stop switch to stop the engine after every use will verify that the switch is working
properly. Remember to turn the key to OFF position after stopping the machine. Not doing so may drain the
battery.
The right food pedal controls blade and engine speed. The position of the foot pedal determines the blade
speed. Slow blade speed is obtained by slightly depressing the pedal. Maximum blade speed is obtained by
fully depressing the pedal.
Keeping your foot OFF the right foot pedal, turn the ignition key fully clockwise and listen for the engine to
start. Once the engine has started, release the ignition key. The throttle speed defaults to idle. Let the engine
warm for a few minutes.
7.2 STEERING
Two control levers located in the front of the operator’s seat provide directional control for the trowel
(fig. 7.2). Table 7.2 illustrates the various directional positions of the control levers and their effect on the ride-
on trowel.

Table 7.2
Push both the left and the right control levers forward (see fig. 7.2).
With your right foot, quickly depress the right foot pedal halfway. Notice that the ride-on power trowel
begins to move in a forward direction. Return both control levers to their neutral position to stop forward
movement, and then remove your right foot from the right foot pedal.
Practice holding the machine in one place as you increase blade speed. When about 75% of maximum blade
speed has been reached, the blade will be moving at proper finishing speed. The machine may be difficult to
keep in one place. Trying to keep the ride-on trowel stationary is good practice for the operator.
Practice maneuvering the ride-on trowel using the information listed in Table 7.2. Try to practice controlled
motions as if you were finishing a slab of concrete. Practice edging and covering a large area.
Try adjusting the pitch of the blades. This can be done with the ride-on trowel stopped or while the trowel is
moving, whichever feels comfortable. Test the operation of optional equipment like retardant spray and
lights.
Push both the left and right control levers backward and repeat steps 3 through 6 while substituting the word
reverse for forward.
NOTICE: Trowel arms can be damaged by rough handling or by striking exposed plumbing or forms while in
operation. ALWAYS look out for objects which might cause damage to the trowel arms.
7.3 BLADE PICH
Sometimes it may be necessary to match blade pitch between the two sets of blades. There are some signs
that this may be necessary. For example, the differences in pitch could cause a noticeable difference in finish quality
between the two sets of blades or, the difference in blade pitch could make the machine difficult to control. This is
due to the surface area in contact with the concrete—the blade set with the greater contact area tends to stick to the
concrete more.
