Exposure to vibration during long periods of work can lead to disorders
of the blood vessels and nervous system in the fingers, hands and wrists.
Electrical safety
▶ Before beginning work, check the working area for concealed electric
cables or gas and water pipes. External metal parts of the power tool may
give you an electric shock if you damage an electric cable accidentally.
Power tool use and care
▶ Secure the workpiece. Use clamps or a vice to hold the workpiece in
position. The workpiece is thus held more securely than by hand and
both hands remain free to operate the power tool.
▶ Immediately switch off the power tool if the accessory tool jams. The
power tool might twist off-line.
▶ Wait until the power tool stops completely before you lay it down.
