The risks involved are to be borne solely by the user. ● Use in accordance with the intended purpose also implies compliance with the conditions laid down by the manufacturer for operation, maintenance and servicing. The engine should only be operated by personnel trained in its use and the hazards involved. ● The relevant accident prevention guidelines and other generally accepted safety and industrial hygiene regulations must be observed. ● When the engine is running, there is a risk of injury through: - turning/hot components - engines with positive ignition - ignition systems (high electrical voltage) You must avoid contact at all times! ● Unauthorized engine modifications will in- validate any liability claims against the manufacturer for resultant damage. Manipulations of the injection and regulating system may also influence the performance of the engine, and its emissions. Adherence to legislation on pollution cannot be guaran- teed under such conditions. ● Do not change, convert or adjust the cooling air intake area to the blower.
