• Ensure that the spot where you wish to work is free of power cables, gas lines or water pipes (e.g. using a metal detector).

Risks associated with dust and vapors

• The dust and vapours generated when the air tool is used may carry health risks (e.g. cancer, birth defects, asthma and/or dermatitis); it is, therefore, imperative that a risk assessment is carried out in relation to these risks and that suitable controls are then implemented.
• The risk assessment should take into account both the dust generated while the air tool is used and any existing dust that may be raised during operation.
• The air tool must be operated in accordance with the recommendations set forth in these instruc-tions and must be maintained in order to minimise the release of dust and vapours.
• The extracted air must be discharged in such a way that the minimum of dust is raised in a dust-filled environment.
• If dust or vapours are generated, the main priority is to control these at the location where they are released.
• All built-in or accessory parts on the air tool that are designed to collect, extract or prevent air-borne dust or vapours must be used and maintained in accordance with the manufacturer’s instructions.
• To avoid increasing the amount of dust or vapours generated unnecessarily, it must ensured that consumables and the accessory are selected, maintained and replaced in accordance with these instructions.
• Use protective breathing apparatus in accordance with your employer instructions or in accordance with health and safety regulations.

Risks associated with noise

• Failure to use adequate ear protectors when the noise level is high can result in lasting damage to hearing, hearing loss and other problems, such as tinnitus (ringing, whistling or buzzing in the ear).
• It is vital to carry out a risk assessment in relation to these risks and to implement appropriate control measures that take the risks into account.
• Appropriate risk control measures may include, for example, the use of sound-insulating materials to prevent the knocking sounds that occur on the workpieces.
• Use ear protection in accordance with your employer instructions or in accordance with health and safety regulations.
• The air tool must be operated in accordance with the recommendations provided in these instruc-tions and must be maintained in order to avoid unnecessarily raising the noise level.
