Notes on correct use Areas of application Overview Dörner + Helmer’s wheels and castors are intended for non-machine-moving vehicles and equipment, hereinafter referred to as objects, which are usually not moved faster than walking speed (4 km/h) and not in continuous operation. Areas of application: Living area, e.g. seating and living room furniture Service sector, e.g. shopping trolleys, office machines Hospital sector Industrial sector, e.g. transport equipment requiring medium and heavy load-bearing capacities Misuse Misuse – i.e. the use of wheels and castors for a purpose which they are not intended for – occurs, for example, if: 2.1 The wheels and castors are used with a higher load than the maximum load-bearing capacity indicated in the catalogue. 2.2 They are used on unsuitable, uneven floors. 2.3 The environmental temperatures are too high or too low. 2.4 A unit with locked castors is moved by force or the locking device is used as a driving brake. 2.5 Particularly aggressive media can have an effect. 2.6 Improper major impacts and damage due to falling over. 2.7 Foreign bodies can penetrate the wheel bandages. 2.8 The wheels and castors are used at an excessively high speed. 2.9 Changes are made which were not approved by the manufacturer. 2.10 Mechanical damage is caused by an external impact or collision. Caution: Castors with soft treads must not be used on unsealed absorbent substrates such as stone, wood or parquet. The white oil found in TPE castors resulting from the production process can leak out and lead to contact discolouration. This oil evaporates from sealed floors without leaving any residues. Grease may leak from the rotating assembly or bearing at high temperatures. Please check floor compatibility before use. On softwood, cork or similar floor coverings, all castors may leave indentations or streaks. Wheel, housing, locking device and axle accessories form a single functional unit. We are liable solely for our original products. All possible loads must be known for the selection of castors. They must otherwise use adequate safety margins. Product maintenance Depending on the demands, wheels and castors must be routinely serviced - by regreasing bearing points - by readjusting detachable connections Suitable greases must be used; in the case of heat-resistant wheels and castors, heat-resistant greases must be used. No cleaning agents having corrosion-promoting or damaging components may be used. Castors and their components must be replaced as soon as functional disturbances occur. Dimensions, illustrations, drawings, etc., are subject to change and are therefore non-binding. Further information can be found in our product liability on page 200 21
