RESPIRATORY HAZARD
INFORMATION
Wear approved respiratory
protection when the
machine is operating
RESPIRATORY HAZARD INFORMATION:
Grinding/cutting/drilling of masonry, concrete, metal and other materials can generate
dust, mists and fumes containing chemicals known to cause serious or fatal injury or
illness, such as respiratory disease, cancer, birth defects or other reproductive harm. if
you are unfamiliar with the risks associated with the particular process and/or material
being cut or the composition of the tool being used, review the material safety data sheet
and/or consult your employer, the material manufacturer/supplier, governmental agencies
such as OSHA, EU-OSHA, and NIOSH and other sources on hazardous materials.
California and some other authorities, for instance, have published lists of substances
known to cause cancer, reproductive toxicity, or other harmful effects.
Control dust, mist and fumes at the source where possible. in this regard use good
work practices and follow the recommendations of the manufacturers or suppliers,
OSHA, NIOSH, and occupational and trade associations. Water should be used for dust
suppression when wet cutting is feasible. When the hazards from inhalation of dust,
mists and fumes cannot be eliminated, the operator and any bystanders should always
wear a respirator that is approved for the materials being used.
SILICOSIS WARNING INFORMATION:
Grinding/cutting/drilling of masonry, concrete, metal and other materials with silica in
their composition may give off dust or mists containing crystalline silica. silica is a basic
component of sand, quartz, brick clay, granite and numerous other minerals and rocks.
Repeated and/ or substantial inhalation of airborne crystalline silica can cause serious
or fatal respiratory diseases, including silicosis. When using the equipment with such
materials, always follow all dust control and respiratory precautions.

IMPORTANT SAFETY INSTRUCTIONS
Read and observe all DANGER, WARNING,
and CAUTION statements included in the
owner’s manual and af xed to the machine.
These statements indicate that there is
a possibility of death, bodily injury, and
damage to the machine or property if these
instructions are ignored.
Operate only in well ventilated areas.
Buildings must be provided with:
A. Acontinuous mechanical ventilation that
removes the products of combustion to the
outdoors of not less than 300 CFM for each
10,000 BTUH or fraction thereof; or
B. Natural ventilation of not less than 300CFM
for each 10,000 BTUH input or a fraction
thereof; based on a maximum of one-quarter
air exchange per hour for the net building
volume.
If you smell LPG gas, stop the unit and check for
leaks. also open windows, don’t touch electrical
switches, extinguish any open ames. Call your
gas supplier if no leaks are found.
Do not adjust the fuel system without the proper
analysis equipment.
DO NOT OPERATE THIS MACHINE IN AN
EXPLOSIVE ENVIRONMENT!
THIS PROPANE MACHINE IS INTENDED FOR
COMMERCIAL USE.
TRANSPORTING THE MACHINE
NEVER TRANSPORT WHILE ENGINE IS
RUNNING.
To transport the machine it is necessary to install
the transport wheel so the drive plates are not in
contact with the oor. In this “balanced” position
the equipment can be readily moved from site to
site.
A. Tilting the Machine
This is a heavy piece of equipment. Caution
should be used in tilting the machine. This can be
accomplished safely and easily as follows:
1. One man method:
a. Standing behind the machine, place one
foot on the brace at the base of the propane
tank.
b. Place one hand on the handle and the
other on the “T” frame handle support.
c. While pulling and leaning back, lift the
other foot off the oor and extend it directly
behind. This will shift the balance and
naturally tilt the equipment to transport or full
“tilt back” position without undue strain.
2. Two man method:
Two people side by side perform the above
procedure simultaneously. This is a safer,
more comfortable technique to use until more
experience is gained with the equipment.
Do not use excessive vertical pressure.
B. Position for Maintenance & Cleaning
To perform certain maintenance & cleaning tasks
or to change diamonds, the machine should be
placed in the full “tilt back” position. See page
8 for more information about maintenance and
cleaning.
PREPARATION
Flange bearing must be lubricated before
every use. See page 8 for more information
about the ange bearing.
A. Check that the suggested maintenance
schedule has been observed. See page 8-9 for
more information about suggested machine and
engine maintenance instructions.
All machines are equipped with a multi-function
maintenance meter. The functions include
the following: hour meter, service alert and
tachometer. (See Engine Maintenance Meter
instructions pg. 9).

B. Check the engine oil before every
operation.
Make sure the machine is level when checking
the oil. Always take 2 readings of the dipstick
before adding oil. If the oil level is below the full
mark, add just enough oil to the engine to bring
the oil level up to the full mark. Never over ll.
Follow the guidelines in your Engine Owners
Manual. Check for foreign material on the
dipstick.
C. Properly ll and check your LPG tank and
all LPG fuel lines for leaks.
1. Every tank has been pressure and
leak tested. However, every time a tank
is lled and/or connected to the machine
it should be soap tested. All LPG lines
must be pressurized and every inch of
line and connections must be sprayed. If
you nd a leak, make the proper repairs
before operating the machine. NOTE: The
connection and disconnection of the LPG tank
must be done in a well ventilated area with
NO source of ignition within 10 feet (3 meters)
from the point of connection.
2. Never over ll the LPG tank! The LPG
tank is designed to hold just 20 pounds of
propane. Make sure to weigh the tank as
it is being lled. The gross weight of a full
tank should not exceed 48 pounds. If while
operating the machine, you notice frost
forming on the LPG lines or the regulator, your
tank has been over lled. If you continue to
operate the machine in this condition, damage
will occur. The excess propane in the tank
must be removed before normal operations
resume. The bleeding of a propane tank
should be done in a safe location outside the
building. In some cases the regulator must
defrost before restarting the engine.
D. Connecting the high pressure hose to the
LPG Tank:
Make sure the couplers are in line and screwed
together hand tight. If this is not done properly,
fuel will not pass through to the regulator. Never
complete the connection of the tanks to the
machine by using a wrench. Always do it by
hand. Listen for the rush of fuel to the lock-out
device when you open the tank valve. If you hear
this, it indicates a good connection has been
made at the tank.
NEVER CHANGE OR ALTER THE PROPANE
CONTROL EQUIPMENT.
NEVER TILT THIS MACHINE ON ITS SIDE.
SAFETY
Provide and use ear protection during
operation.
Never let an untrained person operate or
perform repairs on the machine. They may
hurt themselves, damage the oor or the
equipment.
Engine speed not to exceed 1700 RPM.
DO NOT use machine with a damaged or
disintegrated pad to avoid excess vibration.
