▶Keep the power tool out of reach of children.
▶Avoid touching rotating parts. Switch the power tool on only after
bringing it into position at the workpiece. Touching rotating parts,
especially rotating drill bits or other accessories, may lead to injury.
▶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. 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. Use a dust
removal system whenever possible. To achieve a high level of dust
collection, use a suitable vacuum cleaner. When indicated, wear a
respirator appropriate for the type of dust generated. Ensure that
the workplace is well ventilated. Follow national requirements for
the materials you want to work with.
▶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.
▶Observe the national health and safety requirements.
Careful handling and use of power tools
▶Secure the workpiece. Use clamps or a vice to secure the workpiece.
The workpiece is thus held more securely than by hand and both hands
remain free to operate the power tool.
▶Ensure that the accessory tools used are compatible with the tool-
holder system and that they are correctly secured in the tool holder.
▶In the event of a power failure or interruption in the electric supply,
switch the power tool off, unplug the supply cord and release the
switch lockbutton (if applicable). This will prevent accidental restarting
when the electric power returns.
Electrical safety
▶Before beginning work, check the working area (e.g. using a metal
detector) to ensure that no concealed electric cables or gas and
water pipes are present. External metal parts of the tool may become
live, for example, when an electric power line is damaged accidentally.
This presents a serious risk of electric shock.
▶Check the tool’s supply cord at regular intervals and have it replaced
by a qualified specialist if found to be damaged. If the 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
