Hilti VC 300-20-W Notice D'utilisation Originale page 8

▶ Do not touch the supply cord or extension cord if they are damaged while working. Disconnect
the supply cord plug from the power outlet. Damaged supply cords or extension cords present a risk
of electric shock.
▶ The electric supply cord may be replaced only with a cord of the type specified in the operating
instructions.
▶ Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the appliance. Keep
the cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase
the risk of electric shock.
▶ When operating an electric appliance outdoors, use only extension cords of a type suitable for
outdoor use. Use of an extension cord suitable for outdoor use reduces the risk of electric shock.
▶ In the event of an interruption in the electric supply, switch the appliance off and unplug it from
the power outlet.
▶ Never operate the appliance when it is dirty or wet. Dust (especially dust from conductive materials)
or dampness adhering to the surface of the appliance may, under unfavorable conditions, lead to electric
shock. Dirty or dusty appliances should thus be checked by Hilti Service at regular intervals,
especially if used frequently for working on conductive materials.
2.6 Workplace
▶ Ensure that the workplace is well lit.
▶ Ensure that the workplace is well ventilated. Exposure to dust at a poorly ventilated workplace may
result in damage to the health.
▶ Keep the workplace tidy. Objects which could cause injury should be removed from the working
area. Untidiness at the workplace can lead to accidents.
▶ Do not operate the appliance in explosive atmospheres, such as in the presence of flammable
liquids, gases or dust. Electric appliances cause sparks which may ignite the dust or fumes.
▶ Use extra care when working on stairs.
2.7 The material vacuumed up
▶ Do not use the appliance to vacuum up flammable or explosive dusts (magnesium or aluminum
dust etc.) or dusts that present a health hazard. Do not use the appliance to vacuum up materials
hotter than 60 °C (140 °F), (e.g. glowing cigarette ends, hot ash).
▶ Before starting work, always check the hazard class of harmful dust that can be produced in working
operations. Materials harmful to health such as asbestos and lead are explicitly not included in the
intended use of the product and working with them is not permitted → page 5. If you work with materials
containing lead or asbestos nevertheless, the manufacturer's warranty for your product is voided.
▶ 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 quartz; 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.
▶ Do not use the appliance to vacuum up flammable, explosive or aggressive liquids (coolants and
lubricants, gasoline, solvents, acids (pH < 5), alkalies (pH > 12.5), etc.).
▶ Switch the appliance off immediately if foam or liquids escape from it.
▶ Wear protective gloves when using the appliance to vacuum up hot materials at temperatures of
up to 60 °C (140 °F).
▶ When working with mineral drilling slurry, wear protective clothing and avoid skin contact with the
slurry (pH > 9: caustic).
▶ Avoid contact with alkaline or acidic liquids. If contact accidentally occurs, rinse with water. In
the event of the liquid coming into contact with the eyes, rinse the eyes with plenty of water and
consult a physician.
