▶ Never tamper with or modify the tool in any way.
▶ Apply appropriate safety measures at the opposite side of the workpiece in work that involves breaking
through. Parts breaking away could fall out and / or fall down causing injury to other persons.
▶ You and any other persons in the vicinity must wear suitable eye protection, a hard hat, ear protection,
protective gloves and respiratory protection while the tool is in use.
▶ 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 may cause allergic reactions and/or
respiratory or other diseases to the operator or bystanders. Certain kinds of dust are classified as
carcinogenic such as oak and beech dust, especially in conjunction with additives for wood conditioning
(chromate, wood preservative). Material containing asbestos may be handled only by specialists.
▶ Take breaks between working 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 or gas and water pipes.
External metal parts of the power tool may become live, presenting a risk of electric shock, if you damage
an electric cable accidentally.
Careful handling and use of electric tools
▶ Wait until the power tool stops completely before you lay it down.
