6 Operation
6.1 Grinding
CAUTION
Risk of injury. The accessory tool may suddenly stick or stall.
▶ Use the power tool with the side handle (or optional hoop grip) fitted and always hold the power
tool securely with both hands.
6.2 Cutting
▶ When cutting, apply moderate feed pressure and do not tilt the power tool or the cutting disc (when
working, hold at approx. 90° to the surface being cut).
Note
For best results when cutting profiles and square tube, start cutting at the smallest cross section.
6.3 Rough grinding
CAUTION
Risk of injury. The abrasive cutting disc could shatter and flying fragments may cause injury.
▶ Never use abrasive cutting discs for grinding.
▶ Move the power tool to and fro while maintaining a 5° to 30° angle of attack and applying moderate
pressure.
◁ This will avoid overheating and discoloration of the workpiece and help ensure an even surface finish.
