English / USA !Warning! Be extremely cautious when cutting limbs under tension (spring poles). The limbs could spring back toward the operator and cause loss of control of the saw and severe or fatal injury to the operator. Only properly trained professionals should work in an area where the trees and limbs are tangled. Working in blowdown areas is extremely hazardous. MAINTENANCE, REPAIR AND STORAGE Maintenance, replacement, or repair of the emission control devices and systems may be performed by any nonroad engine repair establishment or individual. However if you claim warranty for a component which has not been serviced or maintained properly or if nonapproved replacement parts were used, STIHL may deny warranty. Never operate a chainsaw that is damaged, improperly adjusted or not completely or securely assembled. Follow the maintenance and repair instructions in the appropriate section of your owner's manual, especially those in the chapters "Mounting the bar and chain", "Maintaining and Sharpening", and "Chain Brake". Only parts supplied or approved by STIHL for the specific model are authorided. Although other parts may fit, their use, in fact, may be extremely dangerous. !Warning! Always stop the engine and ensure that the chain is stopped before making any adjustments, maintenance or repair work, changing the saw chain or cleaning the saw. Do not attempt any maintenance or repair work not described in your owner's manual. Have such work performed at your STIHL service dealer only. !Warning! Never test the ignition system with ignition wire connector removed from spark plug or with unseated spark plug, since uncontained sparking may cause a fire. !Warning! To reduce the risk of fire and burn injury, use only spark plugs authorized by STIHL. Always press spark plug boot snugly onto spark plug terminal of the proper size. (Note: If terminal has detachable SAE adapter nut, it must be attached.) A loose connection between spark plug terminal and ignition wire connector in the boot may create arcing that could ignite combustible fumes and cause a fire. Keep the spark plug clean, and make sure the ignition lead is in good condition. 20 MS 191 T
