▶ Use the product and accessories only when they are in perfect working
order.
▶ Never tamper with or modify the product or accessories in any way.
▶ 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.

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.

tory protection while the product is in use.
