
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
DRAGER gas sampling system with YB ‐ 4620 Drager
detective tubes
GAS ‐ TECH Model CO ‐ 95
ENERAC POCKET 60: Manufactured by Energy
Efficiency System
2) ENGINE EXHUAST
ANALYZERS HORIBA GAS
ANALYZER
ENERAC 2000 COMBUSTION ANALYZER
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 at a time can work with the machine.

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 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 an 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

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
