To change the grinding disc, first unplug the grinder. Press the spindle lock button to prevent the spindle from rotating. Use the supplied wrench to loosen the flange nut, then remove the old disc. Place the new disc onto the spindle and tighten the flange nut securely. Release the spindle lock.
If the grinder is not starting, check that it is plugged into a working power outlet. Inspect the power cord for any damage. Ensure that the power switch is in the "ON" position. If the problem persists, the internal components may need servicing by a professional.
Regularly clean the grinder to remove dust and debris. Check the condition of the power cord and plug. Inspect the grinding disc for wear and replace if necessary. Lubricate moving parts as recommended in the user manual. Store the grinder in a dry, safe place.
Always hold the grinder with both hands during operation. Keep a firm grip on the side handle and the main handle. Ensure the workpiece is securely clamped or supported to prevent movement. Maintain a balanced stance and avoid working in awkward positions.
Overheating can occur if the grinder is overloaded or used continuously for long periods. Allow the grinder to cool down periodically. Make sure the ventilation slots are not blocked. Use the correct type and size of grinding disc for the task.
To replace the carbon brushes, first unplug the grinder. Remove the brush covers on the sides of the motor. Take out the worn brushes and insert new ones of the same model. Replace the brush covers and ensure they are secure.
Wear safety goggles to protect your eyes from flying debris. Use ear protection to safeguard against noise. Wear a dust mask if working in dusty conditions. Gloves and sturdy footwear are also recommended for additional protection.
Kickback can be reduced by ensuring the grinding disc is properly aligned and not binding. Do not force the tool; let the disc do the work. Avoid twisting or tilting the grinder during operation. Ensure the workpiece is stable and secure.
If the disc wobbles, check that it is mounted correctly and the flange nut is tightened securely. Inspect the disc for any signs of damage or wear. If the problem persists, the spindle or flange may be damaged and should be inspected by a professional.
