Operating Instructions
Before operating, ensure you have read and understood all safety instructions.
- Starting the Grinder: With a firm two-handed grip, switch the grinder ON. Allow the disc to reach full speed before making contact with the workpiece.
- Grinding: Apply light, even pressure. Move the grinder smoothly across the surface of the workpiece. Avoid excessive pressure, which can damage the disc and motor. Maintain an angle of approximately 15-30 degrees between the disc and the workpiece for optimal grinding.
- Cutting: For cutting, hold the grinder so the disc is perpendicular to the workpiece. Make shallow passes, gradually increasing the depth of the cut. Do not twist or bind the disc in the cut.
- Stopping the Grinder: Release the ON/OFF switch. Wait for the disc to come to a complete stop before setting the tool down.
- Cooling Down: For prolonged use, allow the grinder to run freely for a few minutes after heavy use to cool the motor.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your tool.
- Cleaning: Regularly clean the ventilation openings to prevent dust buildup, which can cause overheating. Use a soft brush or compressed air.
- Disc Inspection: Before each use, inspect grinding and cutting discs for cracks, chips, or wear. Replace damaged discs immediately.
- Carbon Brushes: The carbon brushes may need replacement after extended use. Consult a qualified service technician for this procedure.
- Power Cord: Inspect the power cord for any damage. If damaged, have it replaced by a qualified electrician to avoid electrical hazards.
- Storage: Store the grinder in a dry, secure place, out of reach of children.
