VEVOR Electric Concrete Floor Grinder User Manual

MODEL: WKG180

Instructions

Thank you very much for choosing this floor grinder. Please read all of the instructions before using it. The information will help you achieve the best possible results.

Parameter List

Introduction and Description

This manual is intended to provide operation and service information necessary for the safe and efficient use of the Floor Grinder. Operating or servicing the unit other than per the instructions given may subject the machine to conditions beyond its capability. This may result in machine failure or personal injury.

IMPORTANT:

Please read the entire operating manual carefully before using 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 fitted with a single-phase motor.

This motor offers a direct drive to the grinding plate through a flexible coupling between the motor and the plate. The shroud allows the operator to maneuver the grinder close to the wall.

The floor grinder has a foldable handle, which makes it easy to transport in the trunk of most vehicles. The wheels can be adjusted for added angle grinding, and the operator can raise or lower the handle’s height to maximize comfort.

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

Operating Instruction

Connect the Vacuum Cleaner

Level and edge grinding

1. Adjust the vertical grinding position by screw the self-aligning bearing seat.
2. Use “bubble-level”, mounted on the machine as a reference.
3. Adjust the wheel by loosening the level adjustment fastener when grinding the corner or wall.

Transport

The machine can be folded to minimize the space needed for transport. Carefully fold the machine forward. Padding should be placed between the motor and the electric box to prevent damage to the machine.

Calibration

The floor grinder is designed for dry use. A suitable industrial vacuum is required. Consult the Safety Data Sheets for the materials being ground. Concrete dust and floor coatings contain harmful materials.

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).

Calibration

1. Ensure that the diamond tooling suits the material being ground and correctly balanced.
2. All countersunk bolts must be tightened to specifications and firmly in place. Take periodic breaks to ensure that bolts are correctly tightened, as they can loosen during operation.
3. Check that the diamond grinding cup wheel is adjusted to sit on the work surface (use the bubble-level on the machine as a reference).
4. Ensure all nuts and bolts on the folding handle latch are tight and secure.
5. Raise the grinding plates from the floor.
6. Start the motor by pressing the switch.
7. Lower the grinding plate and begin grinding. Keep the grinding head moving on the work surface to create an evenly ground surface until the desired results are reached.

Care Instructions

The Floor Grinder has been designed to minimize noise and 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 or use a machine modified by anyone other than the manufacturer or authorized dealers.
4. Do not add weight to the machine. Different grinding diamonds are used to achieve the desired grinding performance.
5. Do not operate the grinder with the grinding head raised higher than necessary. i.e., tipped back on the handle.
6. During normal use, the machine is exposed to vibration. Occasionally, check the machine for loose bolts or nuts.
7. 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. Wherever possible, use engineering controls to control dust, mist, and fumes at the source.

Follow good work practices and the recommendations of the manufacturers/suppliers, OSHA/NIOSH, and occupational and trade associations. When wet grinding/cutting/drilling is feasible, water should be used for dust suppression.

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, or drilling such materials, always follow the respiratory precautions mentioned above.

Troubleshooting

Electric Concrete Floor Grinder Maintenance

• Daily cleaning: The motor should always be kept clean. Water or foreign materials should not be allowed to get into the interior of the motor.
• Check operating amperage draw: While the motor is in operation, takecareto keep the operating amperage below maximumlevel.
• Operational sounds: The motor must not make rubbing sounds, squeals, or other random noises during operation. Stop the motor immediately and restart after inspection and corrections.
• Periodically check the security of the adjustable folding handle latch. The wheel bearings use sealed bearings and require no regular greasing.
