Safety instructions

Image alternative WARNING Study all safety instructions and other instructions, images and technical data with which this product is provided. Failure to observe the instructions below can result in electric shock, fire and/or serious injury.
Keep all safety precautions and instructions for future reference.
The term “power tool” used in the safety precautions refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
  • Study the operating instructions and the safety-relevant information for the system products prior to use and comply with them always.
  • Use the module only in combination with the power tools stated in the section headed Intended use, otherwise there is a risk of injury.
  • Disconnect the plug from the power outlet or remove a removable battery before making any adjustments, changing accessories, or putting away the power tool. This precaution reduces the risk of the power tool starting accidentally.
  • 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.
  • Stay alert, watch what you are doing and use common sense when operating the product. Do not use the product while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating the product can result in serious injury.
  • Working on the material may cause it to splinter. Flying fragments present a risk of injury to the eyes and body. Wear eye protection, a hard hat and ear protection while the product is in use.
  • Use power tools, accessories, insert tools, etc. in accordance with these instructions. Take the working conditions and the work to be performed into account. Use of power tools for applications other than those intended can result in hazardous situations.
  • Risk of injury by falling tools and/or accessories. Before starting work, check that installed accessories are secure.
  • Vacuuming water is prohibited.
  • Do not use the module to vacuum up substances that present a risk of explosion, glowing, burning or flammable substances, aggressive dusts (e.g. magnesium or aluminum dust) and liquids (e.g. gasoline, solvents, acids, coolant/lubricants).
  • 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.
  • Whenever possible, use a Hilti -recommended dust extractor suitable for the application.
  • Before beginning the work, check the hazard classification of the dust that will be produced. Use a dust extractor with an officially approved protection classification in compliance with locally applicable dust protection regulations.
  • Use an anti-static suction hose in order to avoid electrostatic effects.
  • Make sure that the adapter and the outside surfaces of the tool holder are free of oil and grease. If the dust removal module is installed with oily and/or greasy parts, the dust removal module can fall off. Remove oil and grease from the adapter and from the outside surfaces of the tool holder with a cloth.
  • Make sure that the module does not get too hot. The material will melt at temperatures above 80 °C.
  • Do not use the module as a grip for carrying or guiding the system. The power tool has grips designed for this purpose; use these grips.
  • When the power tool is in operation, do not hold it by the suction head or the suction tube.
