Dust produced by grinding, sanding, cutting and drilling can contain dangerous chemicals. Some
examples are: lead or lead-based paints; brick, concrete and other masonry products, natural
stone and other products containing silicates; certain types of wood, such as oak, beech and
chemically treated wood; asbestos or materials that contain asbestos. Determine the exposure of
the operator and bystanders by means of the hazard classification of the materials to be worked.
Implement the necessary measures to restrict exposure to a safe level, for example by the use of a
dust collection system or by the wearing of suitable respiratory protection. The general measures
for reducing exposure include:
▶
working in an area that is well ventilated,
▶
avoidance of prolonged contact with dust,
▶
directing dust away from the face and body,
▶
wearing protective clothing and washing exposed areas of the skin with water and soap.
▶
Always wear a dust mask that meets the requirements of the application.
▶
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 classification in compliance with
locally applicable dust protection regulations.
▶
Comply with national health and safety requirements.
▶
Use clamps or some other practical means to secure the workpiece and keep it in a stable position.
Attempting to stabilize the workpiece by hand or with your body is inadequate and can result in
loss of control. Do not have the workpiece held in position by a helper.
▶
Do not look directly into the light source (LEDs) incorporated in the power tool and do not direct
the light at other persons' faces.
▶
Risk of injury by falling tools and/or accessories. Before starting work, check that installed
accessories are secure.
▶
Bring the saw blade into contact with the workpiece only when the circular saw is switched on.
▶
Use only saw blades recommended by Hilti that comply with the EN 847-1 standard.
Electrical safety
▶
Before beginning work, check the working area (e.g. using a detector) to ensure that no concealed
electric cables or gas and water pipes are present. External metal parts of the power tool can
become live, for example if you accidentally damage electric wiring. This causes an increased risk
of electric shock.
Careful handling and use of batteries
▶
Comply with the following safety instructions for the safe handling and use of Li-ion batteries.
Failure to comply can lead to skin irritation, severe corrosive injury, chemical burns, fire and/or
explosion.
▶
Use only batteries that are in perfect working order.
▶
Treat batteries with care in order to avoid damage and prevent leakage of fluids that are extremely
harmful to health!
▶
Do not under any circumstances modify or tamper with batteries!
▶
Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over
80 °C (176 °F).
▶
Never use or charge a battery that has suffered an impact or been damaged in any other way.
Check your batteries regularly for signs of damage.
▶
Never use recycled or repaired batteries.
▶
Never use the battery or a battery-operated power tool as a striking tool.
▶
Never expose batteries to the direct rays of the sun, elevated temperature, sparking, or open flame.
This can lead to explosions.
▶
Do not touch the battery poles with your fingers, tools, jewelry, or other electrically conductive
objects. This can damage the battery and also cause material damage and personal injury.
