2. SAFETY ISTRUCTIONS
RECOMMENDED USE
The Lavina
®
32G-X machine is designed and
manufactured to grind and polish concrete, terrazzo and
natural stone floors. It can be used for renovations as well
as for polishing. The machine is designed for dry or wet
use. When using it dry, use a vacuum of appropriate size.
For more information, please refer to the chapter on
handling the vacuum connection.
PROHIBITED USE
The machine MUST NOT be used:
For applications different from the ones stated in the
General Description chapter.
For not-suitable materials.
In environments which:
Possess risks of explosion
Possess high concentration of powders or oil substances
in the air
Possess risks of fire
Feature inclement conditions.
Possess electromagnetic radiation.
In nursing homes, hospitals, day-care centers, etc
In areas where loose tiles or other objects are preventing
proper use of the machine.
In rooms without proper ventilation
PREPARATION FOR WORK
Make sure that:
You have closed the work area, so that no person
unfamiliar with operating the machine can enter the area
The tool plate and tools are adjusted to the machine
properly
There are no missing parts of the machine
The machine is in upright working position
The protection devices are working properly.
PROTECTION DEVICES
The machine is equipped with several protection devices
including the following:
An emergency stop button
A protection skirt and a hood for protecting the tool plates.
These devices protect the operator and/or others persons
from potential injuries. Do not remove them. On contrary,
before using the machine, please ensure that all
protection devices are mounted and function properly.
ARREST FUNCTIONS
Functions of arresting of the
machine are following:
Switch to stop the engine
Button to stop the grinding movement
Close the propane tank
SAFE USE
The Lavina
®
32G-X is designed to eliminate all risks
correlated with its use. However, it is not possible to
eliminate the risks of an eventual accident with the
machine. Unskilled or uninstructed operator may cause
correlated residual risks. Such risks are:
Position Risks
due to operator’s incorrect working
position
Tangling up Risks
due to wearing inappropriate
working clothes
Training Risks due to lack of operational training
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.
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.
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 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 3,000 parts per million (ppm)
concentration.
Carbon monoxide is an invisible, odorless,
colorless gas created when fossil fuels (such as gasoline,
wood, coal, propane, oil and methane) burn incompletely.
