– damage to lungs if dust filter mask is not used
- hearing impairment if ear protection is not used
– eye injuries if safety glasses are not used
- vibration injuries if the tool is used for long periods, or is not used or maintained properly.

Vibration

• Declared total vibration values are measured in accordance with a standard test method, and can be used for comparisons between tools.
• The declared values can also be used for a preliminary assessment of exposure.
• Vibration levels can deviate from the declared value, depending on how the tool is used.
• Try as far as possible to reduce exposure to vibrations by, for example, wearing gloves and taking suitable breaks at regular intervals in the work.
• The tool produces an electromagnetic field when in use. This field can in some circumstances affect active or passive medical implants. If you have a medical implant you should consult your doctor and/or the manufacturer of the medical implant before using the tool to reduce the risk of serious or fatal personal injury.

Reduction of noise and vibrations

• Plan the work so that exposure to heavy vibrations is spread over a longer period.

• To reduce noise and vibrations when in use, limit the time the tool is in use, and use low-power/vibration mode and suitable safety equipment.
  • Take the following precautions to minimise the risks of exposure to vibrations and/or noise:

• Only use the tool in accordance with these instructions.
