▶ Wear protective gloves also when changing the accessory tool. Touching the accessory tool presents a
risk of injury (cuts or burns).
▶ Wear eye protection. Flying fragments present a risk of injury to the body and eyes.
▶ Before starting work, check the hazard class of the dust that will be produced when working. Use
an industrial vacuum cleaner with an officially approved protection class in compliance with the locally
applicable dust protection regulations. Dust from materials such as lead-based paint, certain types of
wood and concrete/masonry/stone containing quartz, minerals or metal can be harmful to health.
▶ Make sure that the workplace is well ventilated and, where necessary, wear a respirator appropriate for
the type of dust generated. Contact with or inhalation of the dust can cause allergic reactions and/or
respiratory or other diseases to the operator or bystanders. Certain kinds of dust such as oakwood
and beechwood dust are classified as carcinogenic, especially in conjunction with additives for wood
conditioning (chromate, wood preservative). Only specialists are permitted to handle material containing
asbestos.
▶ Take breaks and do physical exercises to improve the blood circulation in your fingers. 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, gas pipes and water
pipes. External metal parts of the power tool can become live, presenting a risk of electric shock, if you
accidentally damage an electric cable.
Power tool use and care
▶ 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.
