  • Modification of the appliance is not permitted.
  • Use the right appliance for the job. Do not use the appliance for purposes for which it was not intended. Use it only as directed and when in faultless condition.
  • Before beginning work with the appliance, find out how to operate it correctly and about any hazards associated with the materials it will be picking up and how these materials can be disposed of. Take the influences of the surrounding area into account. Do not use the appliance where there is a risk of fire or explosion.
  • The appliance may only be used by persons who are familiar with it, have been trained on how to use it safely and who understand the resulting hazards. The appliance is not intended for use by children. Children must be supervised in order to ensure that they don’t play with the appliance.
  • Store appliances in a secure place when not in use. When not in use, appliances must be stored in a dry, high place or locked away out of reach of children.
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.
Electrical safety
  • The plug on the supply cord of the appliance must match the outlet. Do not change the plug in any way. Do not use adapter plugs with earthed (grounded) appliances. Unmodified plugs and matching outlets reduce risk of electric shock.
  • Insert the plug in a suitable earthed/grounded power outlet which has been correctly and safely installed and is in compliance with local regulations. If you are in doubt about the effectiveness of the power outlet’s earth/ground connection, have it checked by a qualified specialist.
  • Avoid body contact with earthed or grounded surfaces such as pipes, radiators, cookers, stoves and refrigerators. There is an increased risk of electric shock if your body is grounded.
  • Check to ensure that the supply cord does not lie in a puddle of water.
  • Check the appliance’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.
  • 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.
  • 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.
  • Use the power outlet on the appliance only for the purposes described in the operating instructions.
  • 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.
Personal safety
  • Stay alert, watch what you are doing and use common sense when working with the product. Do not use the vacuum cleaner while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating the appliance may result in serious personal injury.

  • Make sure that the vacuum cleaner cannot roll away or fall.
  • Engage the wheel brakes so that the vacuum cleaner stands securely. If the wheel brakes are disengaged the vacuum cleaner may run away out of control.
  • Observe the accident prevention regulations applicable in your country.
  • If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of a vacuum cleaner can reduce dust related hazards.
Safety instructions for vacuum cleaners
  • Before beginning work with the appliance, the operating personnel must be informed about how to operate it correctly and about any hazards associated with the materials it will be picking up and how these materials can be disposed of safely.

  • Use of the appliance for cleaning down persons or animals is not permissible.
    Do not use the appliance for continuous, stationary operation in automatic or semi-automatic systems. Do not stand on top of the appliance (do not use it as a substitute for a ladder).

  • Do not use the appliance under water.

The material vacuumed up
  • Do not use the appliance to vacuum up flammable or explosive dusts or dusts that present a health hazard (e.g. magnesium or aluminum dust). Do not use the appliance to vacuum up materials hotter than 60 °C (140 °F) (e.g. glowing cigarettes, hot ash).
  • Before starting work, check the hazard class of the dust that will be produced when working. Hazardous materials, such as asbestos and lead, are outside the intended use → page 6 of the product and will void the warranty.
  • 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.
  • 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 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.
