FG10 Floor Grinder User’s Manual pg. 3
Introduction and Description
This manual is intended to provide operation and service
information necessary for the safe and efficient use of the
Virginia Abrasives Floor Grinder. Operating or servicing the unit
other than in accordance with the instructions given may subject
the machine to conditions beyond its capability. This may result in
the machine failure or personal injury.
IMPORTANT:
Read the entire operating manual carefully before attempting to
use the floor grinder. Special attention should be given to the
section entitled “Safety Precautions.”
The floor grinder is a sturdy, reliable and easy-to-use machine.
The floor grinder is fitted with a 1.5 hp single phase motor. This
motor offers a direct drive to the grinding plate by way of a
flexible coupling between the motor and the plate.
The shroud system is unique in design by automatically adjusting
to suit segment height and floor angle. This shroud system when
used in conjunction with an appropriate industrial vacuum unit
helps eliminate dust during grinding. The shroud has 2
removable sections to allow the operator to maneuver the grinder
close to the wall. Please note that fugitive dust will likely occur
when using the grinder with the two shroud sections removed.
The floor grinder comes complete with a water connection for wet
grinding, if required. The water connection incorporates a ball
valve that allows the operator to regulate the water supply to
obtain the best grinding results.
The floor grinder has a foldable handle which enables it to be
easily transported in the trunk of most vehicles. The rear wheels
can be extended outward for added stability during use. The
operator can raise or lower the height of the handle to maximize
comfort.
The lightweight design makes the machine easy to lift.

Operation
The floor grinder is designed to be used either wet or dry. If the application
requires dry grinding, a suitable industrial dust collection system is
required.
Consult Safety Data Sheets for the materials being ground. Concrete dust
and floor coatings contain materials that can be harmful. SEE SAFETY
PRECAUTIONS FOR Silica Dust Warning.
Contact your industrial hygiene professional for detailed information on
required personal protective equipment PPE. Always use appropriate
personal protective equipment (Hearing, Eye, Respiratory and Hand
Protection).
Operating the Grinder
1. Make sure the diamond tooling is suitable for the material being ground
and that the tooling is correctly balanced.
2. Ensure that the grinding plates are in good condition and properly
mounted. Never use damaged tooling.
3. All countersunk bolts must be tightened to specifications and firmly in
place. Take periodic breaks to ensure that bolts are properly tightened,
as they can loosen during operation.
4. Check that the grinding plate is adjusted so that it sits level on the work
surface (use the bubble-level on the machine as a reference).
5. Check that all nuts and bolts on the folding handle latch are tight and
secure.
6. Raise the grinding plates from the floor.
7. Start the motor by rotating the switch to the “ON” position.
8. Lower the grinding plate and begin grinding. Keep the grinding head
moving side to side on the work surface to create an evenly ground
surface until the desired results are reached.

Stopping the Grinder
1. Rotate the power switch to the “OFF” position.
Note: The position of the axle may be adjusted as needed for leveling.
Adjusting the Grinding Position
1. Adjust the vertical grinding position by loosening the level adjustment
fastener counterclockwise.
2. Lifting the level adjustment handle raises the back end of the grinder.
3. Lowering the level adjustment handle lowers the back end of the
grinder.
4. Use bubble-level mounted on the machine as a reference.
5. Secure desired grinder position by tightening the level adjustment
fastener clockwise.

Safety Precautions
The Virginia Abrasives Floor Grinder has been designed to minimize
noise, vibration levels and to provide maximum operator safety. However,
incorrect use of the grinder may cause serious injury and therefore the
following precautions must be taken:
1. Do not use the grinder for longer than prescribed in your local
environmental working regulations, as the noise load from
extensive daily use may result in hearing damage.
2. Always use hearing protection, safety glasses, gloves and
appropriate footwear.
3. Do not modify the grinder in any manner. Do not use a machine
that has been modified by anyone other than the manufacturer or
authorized dealers.
4. Do not add weight to the machine. Use different grinding plates to
achieve the desired grinding performance.
5. Do not operate the grinder with the grinding head raised any higher
than necessary. i.e. tipped back on handle.
6. Always be sure that folding handle latch is secure and has not
become loose during use.
7. During normal use the machine is exposed to vibration.
Occasionally check machine for bolts/nuts which may have vibrated
loose.
8. Do not allow water or flammable materials to enter the interior of
the motor.

Respirable Silica Dust Warning
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 Safety Data Sheets (SDS)
and/or consult your employer, the manufacturers/suppliers, governmental
agencies such as OSHA and NIOSH and other sources on hazardous
materials. The state of California and other authorities have published lists
of substances known to cause cancer, reproductive toxicity, or other
harmful effects.
Use engineering controls to control dust, mist, and fumes at the source
wherever possible. Use good work practices and follow the
recommendations of the manufacturers/suppliers, OSHA/NIOSH, and
occupational and trade associations. Water should be used for dust
suppression when wet grinding/cutting/drilling 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 approved by
NIOSH/MSHA for the material being used.
Grinding/cutting/drilling of masonry, concrete and other materials
containing silica may generate 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. The state of California and other
authorities have listed respirable crystalline silica as a substance known to
cause cancer. When grinding/cutting/drilling such materials, always follow
the respiratory precautions mentioned above.

Maintenance
Daily cleaning: The motor should always be kept clean. No water, or
foreign materials should be allowed to get into the interior of the motor.
Check operating amperage draw: While the motor is in operation, take
care to keep the operating amperage below maximum level.
Operational sounds: During operation of the motor there must be no
rubbing sounds, squeals, or other random noises. Stop the motor
immediately and restart after inspection and corrections have been made.
Check the security of the adjustable folding handle latch periodically.
The wheel bearings use sealed bearings and require no regular greasing.
