8 enUse appropriate detectors to determine if utilitylines are hidden in the work area or call thelocal utility company for assistance. Contactwith electric lines can lead to fire and electricshock. Damaging a gas line can lead to explo-sion. Penetrating a water line causes propertydamage or may cause an electric shock.Do not direct the power tool against yourself,other persons or animals. Danger of injuryfrom sharp or hot application tools.Do not rivet or screw any name-plates or signsonto the power tool. If the insulation is dam-aged, protection against an electric shock willbe ineffective. Adhesive labels are recom-mended.Always work using the auxiliary handle. Theauxiliary handle ensures reliable guidance ofthe power tool.Before putting into operation, check the mainconnection and the main plug for damage.Handling hazardous dusts.When working with powertools, such as when grinding,sanding, polishing, sawing or for other workprocedures where material is removed, dustsdevelop that are both hazardous to one’s healthand can spontaneously combust or be explo-sive.Contact with or inhaling some dust types cantrigger allergic reactions to the operator orbystanders and/or lead to respiratory infec-tions, cancer, birth defects or other repro-ductive harm.Examples of such materials and therein con-tained chemicals, where hazardous dusts candevelop when working them, are:– Asbestos and materials containing asbestos;– Lead-containing coatings, some wood typessuch as beech and oak;– Minerals and metal;– Silicate particles from bricks, concrete andother materials containing stone;– Solvent from solvent-containing paint/var-nish;– Arsenic, chromium and other wood pre-servatives;– Materials for pesticide treatment on bootand ship hulls;To minimise the unwanted intake of thesematerials:– Use dust extraction matched appropriatelyfor the developing dust.– Use personal protective equipment, such asa P2 filter-class dust protection mask.– Provide for good ventilation of the work-place.The risk from inhaling dusts depends on thefrequency how often these materials are wor-ked. Materials containing asbestos may onlybe worked by specialists.Wood and light-metal dust cancause spontaneous combustionor explosions.Hot mixtures of sanding dust and paint/var-nish remainders or other chemical materialsin the filter bag or the vac filter can self-igniteunder unfavorable conditions, such as spar-king from sanding metal, continuous sunlightor high ambient temperatures. To preventthis:– Avoid overheating the material being san-ded and the power tool.– Empty the dust collector/container in time.– Observe the material manufacturer’s wor-king instructions.Observe the relevant regulations in yourcountry for the materials being worked.WARNINGCAUTION3 41 01 121 21 0.book Seite 8 Montag, 22.
