Stihl SR 450 Product Instruction Manual - Page 7

Warning! In limited circumstances, mistblowers may also be used in greenhouses that are very well-ventilated if the operator can protect himself or herself from any harmful effects through the use of proper eye, skin and respiratory protection. Such work may require special precautions, and must not be prohibited on the chemical product label. THE POWER TOOL For illustrations and definitions of the power tool parts see the chapter on "Main Parts and Controls." Warning! Never modify this power tool in any way. Only attachments supplied by STIHL or expressly approved by STIHL for use with the specific STIHL model are authorized. Although certain unauthorized attachments are useable with STIHL power tools, their use may, in fact, be extremely dangerous. If this tool is subjected to unusually high loads for which it was not designed (e.g. heavy impact or a fall), always check that it is in good condition before continuing work. Check in particular that the fuel system is tight (no leaks) and that the controls and safety devices are working properly. Do not continue operating this machine if it is damaged. In case of doubt, have it checked by your STIHL servicing dealer. Dusting and spreading mode - SR 450 only The dusting and spreading mode can be used for powder or dry granulate up to a grain size of 5 mm. Observe all legal requirements for handling the chemicals. Observe the directions for use on the label of the product at issue. Using the dusting and spreading mode Warning! An electrostatic charge may be created in the extension tube and nozzle area when applying dry materials (e.g. dusts) with the dusting and spreading attachment. This is especially true in low humidity conditions. Check the label and/or material safety data sheet for the chemical you are applying. To reduce the risk of severe or fatal injury, do not use your mistblower to apply substances that may create a combustible or explosive dust cloud. For instance, never use your mistblower to apply sulfur or sulfur compounds, since they may be highly explosive and have relatively low melting and ignition points. English Warning! To reduce the risk of sparking when applying any dry substance, make sure that the discharge system (antistatic wire in the mistblower connected to a metal chain) is completely and properly mounted to the machine, and that the discharge chain is making contact with the ground. It is essential to follow the assembly instructions - see the chapter "Assembling the Unit" in this instruction manual. Do not use the dusting and spreading attachment on non-conductive surfaces (e.g. plastic, asphalt). Never operate your machine with a missing or damaged discharge system. 0002BA001 KN SR 430, SR 450 5
