Certain residual risks remain present, even when the device is operated in the prescribed manner. The following dangers can be present when using the device:
Vibration can cause injuries. Use the correct tools for the job, use the handles provided and restrict the working time and hazard exposure time.
Noise can cause hearing injuries. Wear hearing protection and limit the duration of exposure.
Injuries due to flung objects.
Risk reduction
CAUTION
Using the device for longer periods can cause poor circulation in the hands due to vibrations. A general period of use cannot be set, because this depends on several influencing factors:
Personal tendency to suffer from poor circulation (frequently cold fingers, tingling sensation in the fingers)
Low ambient temperature. Wear warm gloves to protect your hands.
Holding the device too tightly hindering blood circulation.
Continuous operation is more harmful than operation interrupted by work breaks.
You should see a doctor if using the device regularly and for lengthy periods of time, and in the event of repeated occurrences of symptoms such as tingling in the fingers or cold fingers.
