  • 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.
  • The product is intended for professional use. The product may be serviced and repaired only by authorized, trained personnel! This personnel must be specially informed of any possible hazards.
  • 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.
  • 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.
  • 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 TE DRS-B dust removal module is installed with oily and/or greasy parts, the TE DRS-B 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.
