▶ 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.
▶ Take frequent breaks and do physical exercises to improve the blood
circulation in your fingers. High vibration during long periods of work can
lead to disorders of the blood vessels and nervous system in the fingers,
hands and wrists.
▶ Do not look directly into the light source (LED) of the product and do not
aim the beam at other persons' faces. Risk of dazzling or eye damage.
▶ In the event of a fault affecting the control switch, high torque and high
speeds when the drill / driver is used can lead to injuries. Under these
circumstances, stop working with the drill / driver.
▶ Do not touch metal objects while working with the drill / driver.
▶ Do not use the product to work on hazardous materials (e.g. asbestos).
▶ If the work involves breaking right through, take the appropriate safety
measures on the opposite side. Parts breaking away could fall out and/or
fall down, causing injury to other persons.
▶ Risk of injury by falling tools and/or accessories. Before starting work,
check that the battery and installed accessories are secure.
Electrical safety
▶ Before beginning work, check the working area for concealed electric
cables or gas and water pipes. External metal parts of the product could
give you an electric shock or cause an explosion if you accidentally
damage an electric cable or a gas or water pipe.
Power tool use and care
▶ Switch the product on only after you have brought it to the working
position.
▶ Switch the product off immediately if the accessory tool jams. The
product might twist off-line.
▶ Wait until the product has come to a complete stop before you lay it
down.
