FAQs

What type of grinding disc should I use?

Use 5" (125mm) grinding discs that are specifically rated for angle grinders and have an RPM rating equal to or greater than the grinder's 10,000 RPM free speed.

Do I need to lubricate the tool?

Yes, regular lubrication via the air inlet with specialized air tool oil is crucial for maintaining performance and extending the tool's lifespan. Use a few drops before each extended use or as recommended by the manufacturer's instructions if available.

What is the purpose of the anti-rotation guard?

The anti-rotation guard is a safety feature designed to prevent the guard from spinning around the tool if the grinding disc breaks during operation, offering increased protection to the user.

Can this grinder be used for cutting metal?

Yes, with the appropriate cutting disc installed, this angle grinder can be used for cutting metal. Ensure the disc is rated for the task and the grinder's speed.

What maintenance is required?

Regular lubrication, keeping the air intake clean, and checking connections are key. Periodically inspect the tool for wear and tear, and replace worn parts as needed.

How much air does this grinder need?

The grinder requires a minimum of 6 CFM (Cubic Feet per Minute) of airflow from your compressor and operates at 90 PSI (Pounds per Square Inch).

Troubleshooting

Grinder not starting or running slowly

Check air supply connection, ensure compressor is providing adequate pressure (90 PSI) and airflow (6 CFM). Inspect air line for kinks or blockages. Ensure the tool is adequately lubricated.

Excessive vibration during operation

Ensure the grinding disc is correctly mounted and balanced. Check for damage to the disc. Verify the side handle is securely attached.

Reduced power output

Confirm air supply meets specifications. Check for air leaks in the hose or connections. Clean the air intake filter if present. Ensure proper lubrication.

Overheating during use

Reduce the grinding pressure. Ensure adequate airflow. Check if the selected speed is appropriate for the material and task. Do not operate continuously at maximum load without breaks.

Setup, Compatibility & Care

Setup:

  1. Ensure your air compressor is switched off and depressurized.
  2. Connect a suitable 1/4" BSP air hose to the grinder's air inlet.
  3. Connect the other end of the air hose to your compressor's output.
  4. Attach the side handle securely to the grinder body.
  5. Install the grinding disc using the appropriate locking mechanism, ensuring it is rated for the grinder's speed.
  6. Adjust the anti-rotation protective guard to a suitable position for your work.
  7. Connect to a lubricated air source if your compressor system includes an oiler, or use an inline lubricator.

Compatibility:

  • Air Pressure: Operates optimally at 90 PSI.
  • Air Flow: Requires a compressor capable of delivering at least 6 CFM.
  • Air Inlet: Standard 1/4" BSP fitting.

Care:

  • Lubrication: Regularly lubricate the air inlet with air tool oil to ensure smooth operation and longevity.
  • Cleaning: After each use, disconnect the air supply and wipe down the grinder with a dry or slightly damp cloth. Ensure no dust or debris enters the air intake.
  • Storage: Store in a clean, dry environment. Avoid extreme temperatures.
  • Disc Replacement: Replace grinding discs when worn or damaged. Always ensure the new disc's RPM rating meets or exceeds the grinder's maximum RPM.
