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 newly designed lifting handle system makes the machine easy to lift.

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 pressing the black switch on the starter box.

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

Depress the red stop button on the start box.

Note:

The position of the axle may be adjusted as needed for leveling.

1.Adjust the vertical grinding position by loosening the level adjustment

fastener counter clockwise.

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 Bycon 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, goggles, 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,metaland 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.

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.
