The water hose must move freely and must be damage‐
free.
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
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 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.
