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
contact with a pilot light from a furnace, hot water heater,
or other source of ignition. Propane changes into a gas, is -
44º F (-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.
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
