Stihl MS 461 Rescue Instruction Manual - Page 12

English be followed as described in your manual. Always make sure the hexagonal nut(s) for the sprocket cover is (are) tightened securely after tensioning the saw chain in order to secure the bar. Never start the chain saw with the sprocket cover loose. Check chain tension once more after having tightened the nut(s) and thereafter at regular intervals (whenever the saw is shut off). If the saw chain becomes loose while cutting, shut off the engine and then tighten. Never try to adjust the saw chain while the engine is running. WARNING After adjusting a saw chain, start the chain saw, let the engine run for a while, then switch engine off and recheck saw chain tension. Proper saw chain tension is very important at all times. Keep the handles clean and dry at all times; it is particularly important to keep them free of moisture, pitch, oil, fuel mix, grease or resin in order for you to maintain a firm grip and properly control your chain saw . WARNING Be sure that the guide bar and saw chain are clear of you and all other obstructions and objects, including the ground. If the upper quadrant of the tip of the bar touches any object, it may cause kickback to occur (see section on reactive forces). Never attempt to start the chain saw when the guide bar is in a cut or kerf. For specific starting instructions, see the appropriate section of your instruction manual. Depth Limiter The depth limiter is intended for the use only on the STIHL "Rescue Saw" for fire and rescue operations by specially trained personnel. The cutting depth or plunge depth of the cutting attachment can be set by means of a sliding metal sleeve that is moveable within a preset range along a specially prepared guidebar. Its sole purpose is to limit the depth of entry into material, which may be useful to fire and rescue personnel when cutting into walls, etc. It is not designed to protect the operator from saw chain contact. The additional weight of the depth limiter will make the chain saw more nose-heavy. For mounting instructions see the chapter entitled "Depth Limiter" in this manual. Starting WARNING To reduce the risk of fire and burn injuries, start the engine at least 10 feet (3 m) from the fueling spot, outdoors only. Start and operate your chain saw without assistance. For specific starting instructions, see the appropriate section of the instruction manual. Proper starting methods reduce the risk of injury. WARNING To reduce the risk of injury from saw chain contact and / or reactive forces, the chain brake must be engaged when starting the chain saw. If your chain saw is equipped with the Quickstop Plus chain brake system, it is not sufficient to engage that brake only for starting, because the saw chain may begin to rotate at high speed when the throttle trigger lockout is depressed (releasing the brake) in order to blip the throttle trigger after starting. WARNING Do not drop start. This method is very dangerous because you may lose control of the chain saw. There are two recommended methods for starting your chain saw. With the first recommended method, the chain saw is started on the ground. Make sure the chain brake is engaged (see "Chain Brake" chapter in your instruction manual) and place the chain saw on firm ground or other solid surface in an open area. Maintain good balance and secure footing. Grip the front handlebar of the saw firmly with your left hand and press down. For saws with a rear handle level with the ground, put the toe of your right foot into the rear handle and press down. With your right hand pull out the starter grip slowly until you feel a definite resistance and then give it a brisk, strong pull. 001BA113 KN 10 MS 461 R
