▶ 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 cutting discs 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.
