2.1 Legend
Notation regarding safety
Notation regarding electrical safety
Notation regarding safety during transport
Tipping hazard
See reference
2.2 Safety precautions
Any machine, if it is not used according the regulations, may be hazardous for operating,
setting-up and service personnel. The operating authority is responsible for compliance with
the safety regulations during operation and maintenance, and for the use of safety devices
supplied with the machine, as well as the provision of appropriate additional safety devices!
Eye and ear protection must be worn at all times.
Never operate the machine when it’s not in its upright position.
Make sure there is no debris in the work area.
Check the work area for screws or other hard objects in the surface. Don’t use the machine if
there are any foreign objects stuck into the surface. Such objects must be removed prior to
operation of machine.
Read “2.33 Propane safety and “2.10 Safety regarding operation of machine” thoroughly
before operation!

ScanCombiflex 650 PROPANE - Manual

2.3 Propane safety
Propane is a flammable gas whose vapors are heavier than air. As in 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 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 machines are:
Carbone Monoxide Poisoning: This is the most frequently reported incident
associated with propane powered 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 emission control
technology and improperly set carburetion.
Overfill Fuel Tanks: Nearly all fire related incidents reported result from bringing a
tank into a building without first checking for overfill. This action is dangerous,
unwise and unnecessary.
2.4 Fire Safety
Beware of the potential danger of fire or explosion when using propane, and take
normal fire-safety precautions.
Fire: There is possibilities of fire from LPG vapor Leaking or venting from fuel
tanks 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.
2.5 Emissions
All propane powered floor 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) concentrations.
Carbon monoxide is an invisible odorless colorless gas created when fossil fules
(such as gasoline, wood, coal, propane, oil and methane) burn incompletely.
2.6 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 machine,
do the following:

ScanCombiflex 650 PROPANE - Manual
- 9 -
1. Stop the engine: Push the throttle to the stop position 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.
2.7 Local agencies and regulations
• NFPA
Operating a propane powered floor 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.

ScanCombiflex 650 PROPANE - Manual
- 10 -
• 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 tanks 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 abovementioned
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.
2.8 Organizational measures
The Manual is to be kept near the location where the machine is being operated and must be
within reach at all times.
In addition to this Manual general and legal regulations regarding accident prevention and
environmental protection must be complied with as per local regulations.
Such duties may, for example, relate to the handling of hazardous substances, or to the
provision and wearing of personal protection equipment, as well as compliance with traffic
regulations.
The Manual must be supplemented by other instructions, including the duty to supervise and
report incidents relating to particular working practices, for example work organization,
work procedures and personnel safety.
Personnel entrusted with working with the machine must read the Manual before starting
work, in particular the “2Safety Regulations” chapter. To read these instructions after work

ScanCombiflex 650 PROPANE - Manual
- 11 -
is commenced is too late. This particularly applies to incidental activities such as setting up
the equipment, carrying out maintenance work or training staff to work with the machine.
From time to time the working practices of the operators are to be checked by a supervisor
especially to the items regarding awareness of safety and hazards.
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.
Operators must tie back long hair, and not wear loose clothing or jewelry including rings.
There is a risk of injury through items getting caught, or being drawn into moving
machinery.
Eye and ear protection must be worn at all times!
Use personnel protection equipment if necessary or required by local regulations! Take
notice of all safety and hazard notices on the machine!
All safety and hazard notices at or on the machine must be kept complete and legible!
If safety-critical changes occur to the machine or its working method, the machine must be
shut down immediately! The cause of the fault must be established, and rectified.
Changes, add-ons or conversation to the machine, which might impair safety, must not be
made, without the manufacturer’s permission!
This applies in particular to the fitting and adjustment of safety devices.
Spare parts must comply with the technical requirements specified by the manufacturer. This
is always guaranteed if original spare parts are used.
Intervals for recurring checks and inspections specified in this Manual must be complied
with!
To perform maintenance work correctly it is imperative to be equipped with the proper tools
for the task in question.
Repairs may only be made by Scanmaskin Sweden AB certified service technicians.
Some grinding work may generate sparks under certain circumstances. Personnel working
with the machine must therefore be aware of the risk of fire and how to handle a fire
situation properly.
Do not use the machine in areas with highly flammable and/or explosive materials.

Do not switch off or remove the exhaust and or the ventilation devices whilst the machine is
running!
All persons in the proximity of the machine must wear ear and eye protection as well as
safety shoes. In addition the machine operator must wear close-fitting protective clothing.
Make sure there is no debris in the work area.
Check the work area for screws or other hard objects in the concrete. Don’t use the machine
if there are any foreign objects stuck into the surface. Such objects must be removed prior to
operation of machine
2.11 Electrical safety
The battery power source must be equipped fused according to the table in “1.1Power
specifications”.
Work on electrical equipment may only be undertaken by a skilled electrician or by trained
persons under the supervision of a skilled electrician as well as in accordance with the local
electrical engineering regulations.
The work area must be secured against any third party entering the work area. Follow local
electrical engineering regulations while working on the machine. Never leave a machine
unattended. Use only tools that are insulated against electricity.
Only start work after you are familiar with the electrical engineering regulations that apply
to the local area.
Only use voltage seekers that comply with the regulations when troubleshooting. From time
to time check voltage seekers to ensure that they are operationally efficient.
2.12 Propane tanks
The Propane tanks are constructed of either aluminum or steel. The tank used on propane
powered floor machines is classified as a 4E240 cylinder. Its rated capacity is 20lbs. and this
designation refers to the model of the tank. Actual propane capacity achieved during filling
can be less than, equal to, or slightly more than 20 lbs. Use only UL, CTC/DOT listed tanks.
• The propane tanks 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 tanks (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.

ScanCombiflex 650 PROPANE - Manual
- 14 -
2.13 Refilling propane tanks
The proper filling of propane tanks is a subject so important that it warrants special attention.
Propane tanks should only be filled by qualified propane dealers.
• Most important, propane tanks 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 -44" F (-42° C). Exposing unprotected skin to propane gas or liquid could result
in frostbite injury.
• All new tanks should be vented and purged of air per manufacturer's instructions before
use. Never bleed propane tanks indoors.
2.14 Storage propane tanks
When not in use, propane tanks 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.
2.15 Transporting propane tanks
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
