Stihl SR 450 Product Instruction Manual - Page 11

English Warning! To reduce the risk of injury from thrown parts, check the fan housing for damage (cracks, nicks, chipping). If any damage is found, stop using the unit and contact your STIHL dealer for repair. Check condition of harness straps and replace damaged or worn straps. Warning! Adjust carrying harness to suit your size before starting work. In an emergency, you may slip out of the harness and throw off the machine quickly. Try slipping out of the harness a number of times before using the machine in order to become accustomed to it. Do not throw off the machine while practicing as it could damage the machine. Starting Start the engine at least 10 feet (3 m) from the fueling spot, outdoors only. Warning! Your power tool is a one-person machine. To reduce the risk of eye or other injury from thrown objects, insure that bystanders are at least 50 feet (15 m) away when starting and during use. Stop operation immediately if you are approached. For specific starting instructions, see the appropriate section in this instruction manual. Place the power tool on firm ground or other solid surface in an open area. Maintain good balance and secure footing. SR 430, SR 450 Warning! When you pull the starter grip, do not wrap the starter rope around your hand. Do not let the grip snap back, but guide the starter rope to rewind it properly. Failure to follow this procedure may result in injury to your hand or fingers and may damage the starter mechanism. The assistance of another person may be needed in placing the unit on your back after starting. In order to reduce the risk of injury to the assistant from thrown objects, chemical spray/dust or from contact with hot exhaust fumes, the engine should be kept at idle speed during this brief period, and your assistant should not stand in the area of the outlet nozzle or exhaust. Otherwise, the unit should be started and operated without assistance. During Operation Holding and Controlling the Power Tool The mistblower is designed for singlehanded operation with the right hand on the control handle. It should be carried as a backpack with the straps of the harness over both shoulders. 0002BA002 KN Warning! To reduce the risk of loss of control, never carry the unit with the strap(s) over one shoulder. Wrap your fingers tightly around the handle, keeping the control handle cradled between your thumb and forefinger. Keep your hand in this position to have your machine under control at all times. Warning! In order to keep the container upright and reduce the risk of spillage, do not bend at the waist. Bend only at the knees and support yourself as required to ensure proper balance. Remember that a mistblower filled with liquid has a significant amount of weight. Use caution when bending, leaning or walking. Warning! Do not overreach. Keep proper footing and balance at all times. Special care must be taken in slippery conditions (wet ground, snow and ice) and in difficult, overgrown terrain. Watch for hidden obstacles such as tree stumps, roots and ditches to avoid stumbling. For better footing, clear away fallen branches, scrub and cuttings. Be extremely cautious when working on slopes or uneven ground. To reduce the risk of stumbling and loss of control, do not walk backward while operating the machine. Avoid stepping on antistatic chain - SR 450 only. 9
