Stihl FS 91 Instruction Manual - Page 10

English A B Arrows on the deflector (A) and limit stop (B) (as seen from the underside) show the correct direction of rotation of the cutting attachment. When viewed from above, however, the cutting attachment rotates counterclockwise. Adjust carrying harness and hand grip to suit your size before starting work. The machine should be properly balanced as specified in your instruction manual for proper control and less fatigue in operation. To be better prepared in case of an emergency, practice releasing the unit from the harness as quickly as possible. Starting Start the engine at least 10 feet (3 m) from the fueling spot, outdoors only. For specific starting instructions, see the appropriate section of your manual. Place the power tool on firm ground or 000BA007 KN 000BA006 KN other solid surface in an open area. Maintain good balance and secure footing. WARNING To reduce the risk of injury from blade or line contact, be absolutely sure that the cutting attachment is clear of you and all other obstructions and objects, including the ground, because when the engine starts at starting-throttle, engine speed will be fast enough for the clutch to engage and move the cutting attachment. Once the engine has started, immediately blip the throttle trigger, which should release the starting throttle and allow the engine to slow down to idle. With the engine running only at idle, attach the power tool to the spring hook of your harness (see appropriate chapter of this manual). WARNING Your power tool is a one-person machine. Do not allow other persons in the general work area, even when starting. WARNING To reduce the risk of injury from loss of control, do not attempt to "drop start" your power tool. 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. Important Adjustments WARNING To reduce the risk of personal injury from loss of control or contact with the running cutting attachment, do not use your unit with incorrect idle adjustment. At correct idle speed, the cutting attachment should not move. For directions on how to adjust idle speed, see the appropriate section of your instruction manual. If you cannot set the correct idle speed, have your STIHL dealer check your power tool and make proper adjustments and repairs. During Operation Holding and Controlling the Power Tool Always hold the unit firmly with both hands on the handles while you are working. Wrap your fingers and thumbs around the handles, keeping the handles cradled between your thumb and forefinger. Keep your hands in this position to have your power tool under control at all times. Make sure your trimmer handles and grips are in good condition and free of moisture, pitch, oil, fuel mix or grease. Make sure you always have good balance and secure footing. 8 FS 91, FS 91 R
