5. Technical Guidance & FAQ
What can I use this grinder for? Can I fit a wood-cutting saw blade?
Use it for metal cutting, weld grinding, rust removal and surface preparation. Choose a cutting or grinding disc suited to the task, and use the appropriate guard and auxiliary handle. Do not fit a toothed wood-cutting saw blade. Use a tool and blade designed for cutting wood.
Will any 100 mm disc fit?
No. This model uses a 100 mm disc and M10 spindle, but the disc bore, thickness, flange and guard must also match. M10 is the spindle thread, not the disc bore size. The disc's rated speed must be at least the maximum speed marked on the tool. Remove the battery before changing accessories, and never use a damaged or incompatible disc.
Why does the grinder build up speed gradually when I switch it on?
The soft-start function increases speed gradually to reduce the initial jolt and reaction force. A smooth increase in speed is normal; you do not need to switch the tool off and on repeatedly. Persistent loss of power, unusual vibration or abnormal noise is not normal soft-start behavior. Stop using the tool if this occurs.
Can I use another brand's battery if it is also labeled 21V?
A 21V label or similar appearance does not establish compatibility. Use the battery specified for this tool and its matching charger, checking the full model numbers, connector and locking mechanism. Do not mix batteries and chargers from different platforms.
