▶ Always hold the tool securely by the grips provided. Keep the grips dry, clean and free from oil and
grease.
▶ Wear protective gloves also when changing the accessory tool. Touching the accessory tool presents a
risk of injury (cuts or burns).
▶ 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.
▶ The tool is not intended for use by debilitated persons who have received no special training.
▶ Keep bystanders, children and visitors away while operating a 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 classification in compliance with locally
applicable dust protection regulations.
▶ Use a dust removal system and suitable vacuum cleaner whenever possible. Dust from materials, such
as paint containing lead, some wood species, concrete/masonry/stone containing silica, and minerals as
well as metal, may be harmful.
▶ 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.
▶ Observe the national health and safety requirements.
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.
▶ Check the power tool's supply cord at regular intervals and have it replaced by a qualified specialist if
found to be damaged. If the power tool's supply cord is damaged it must be replaced with a specially-
prepared and approved supply cord available from Hilti Customer Service. Check extension cords at
regular intervals and replace them if found to be damaged. Do not touch the supply cord or extension
cord if it is damaged while working. Disconnect the supply cord plug from the power outlet. Damaged
supply cords or extension cords present a risk of electric shock.
Careful handling and use of electric tools
▶ Secure the workpiece. A workpiece clamped in a vice or secured by some other clamping device is more
secure than when held only by hand.
▶ Ensure that the accessory tools used are compatible with the tool-holder system and that they are correctly secured in the tool holder.
▶ Switch the electric tool off and unplug the supply cord in the event of an interruption in the electric supply
in order to avoid inadvertent restarting when the power returns.
