▶ Wear suitable protective glasses, a hard hat, ear protection, protective gloves and light respiratory
protection while using the power tool.
▶ Before beginning the work, check the hazard classification of the dust that will be produced. 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 may 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 among operators 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 give you an electric shock if you damage an electric cable
accidentally.
▶ Do not touch the supply cord or extension cord if it is damaged while working. Disconnect the mains
plug from the power outlet. Check the tool's supply cord at regular intervals and have it replaced by Hilti
Service if damage is found. Check extension cords at regular intervals and replace them if found to be
damaged.
Using and handling power tools with care
▶ Do not use cut-off wheels for grinding.
▶ Remove the clamping flange from the arbor before fitting a threaded accessory tool.
▶ Tighten the accessory tool and flange securely. If the accessory tool and flange are not tightened
securely, the accessory tool may work loose from the arbor due to the braking effect of the motor after
switching off.
▶ Comply with the manufacturer's instructions for handling and storing grinding discs.
