Stihl HT 105 Instruction Manual - Page 16

English WARNING Do not operate your power tool if the muffler is damaged, missing or modified. An improperly maintained muffler will increase the risk of fire and hearing loss. Your muffler is equipped with a sparkarresting screen to reduce the risk of fire; never operate your power tool if the screen is missing, damaged or clogged. Remember that the risk of a brush or forest fire is greater in hot or dry weather. In California, it is a violation of § 4442 or § 4443 of the Public Resources Code to use or operate gasoline-powered tools on forest-covered, brush-covered or grass-covered land unless the engine's exhaust system is equipped with a complying spark arrester that is maintained in effective working order. The owner/operator of this product is responsible for properly maintaining the spark arrester. Other states or governmental entities/agencies, such as the U.S. Forest Service, may have similar requirements. Contact your local fire agency or forest service for the laws or regulations relating to fire protection requirements. WARNING Keep the chain, bar and sprocket clean; replace worn sprockets or chains. Keep the chain sharp. You can spot a dull chain when easy-to-cut wood becomes hard to cut or burn marks appear on the wood. Keep chain at proper tension. Tighten all nuts, bolts and screws except the carburetor adjustment screws after each use. For maintenance items please also refer to the maintenance chart in this manual. Do not clean your machine with a pressure washer. The solid jet of water may damage parts of the machine. Store the power tool in a dry and high or locked location out of reach of children. Before storing for longer than a few days, always empty the fuel tank. See chapter "Storing the machine" in this manual. Store fuel and chain oil in approved and properly labeled safety-type canisters only. Take care when handling gasoline. Avoid direct contact with the skin and avoid inhaling fuel vapor.
