Powering On/Off

To turn the grinder on, slide the switch forward until it locks into the ON position. To turn it off, press the rear of the switch to release the lock and slide it back to the OFF position. The soft start feature ensures a smooth startup.

Adjusting Speed (Vario-Constamatic)

Grinding and Cutting Techniques

• Always hold the grinder firmly with both hands.
• Allow the disc to reach full operating speed before contacting the workpiece.
• Apply consistent, moderate pressure. Do not force the tool.

• For grinding, use a grinding disc and move the tool smoothly across the surface.

Regular maintenance ensures the longevity and safe operation of your Metabo angle grinder.

• Cleaning: Regularly clean the ventilation slots to prevent dust buildup, which can cause overheating. Use compressed air to blow out debris.
• Cord Inspection: Periodically inspect the power cord for damage. Do not use the tool with a damaged cord.
• Brush Inspection: Carbon brushes should be checked periodically by a qualified service technician.
