5 IMPORTANT SAFETY INSTRUCTIONS 5.6 Using the Chain Saw 5.6.1 Before Operation WARNING ■ Misuse or unauthorized use may result in personal injury and property damage. - Use the chain saw only as described in this instruction manual. ■ For proper assembly of the bar and chain: - Read and follow the instructions on mounting the guide bar and chain, @ 10.2.1. ■ The chain, guide bar and sprocket must match each other in gauge and pitch. Before mounting or replacing: - Read the information on guide bar and chain combinations, @ 25. - Read and follow the instructions on kickback and other reactive forces, @ 6. - Select the shortest bar that will meet your cutting needs. Longer bars add weight and may be more difficult to control. ■ Proper tension of the chain is extremely important to maximize cutting performance and reduce the risk of personal injury from chain breakage, derailment or reactive forces: - Never cut with a loose chain. If the chain becomes loose while cutting, engage the chain brake and shut off the engine before tightening the chain. Never attempt to adjust the chain while the engine is running. - Read and follow the chain tensioning instructions, @ 10.3. - Always make sure the chain sprocket cover is tightened securely after tensioning the chain in order to secure the bar. Never start the chain saw with the chain sprocket cover loose or missing. - Check chain tension once more after tightening the chain sprocket cover. English - After adjusting the chain, let the motor run for a minute or two, then shut off the engine, engage the chain brake and recheck chain tension. - Check chain tension periodically thereafter at regular intervals (only after engaging the chain brake and shutting off the engine). ■ To reduce the risk of fire and explosion: - Check fuel system for leaks, especially the visible parts, (e.g., filler cap, hose connections). - Securely mount the spark plug boot on the spark plug. - Do not start the engine if the fuel system has leaks or the saw is otherwise damaged. Have the chain saw repaired by an authorized STIHL servicing dealer before using it. ■ Using a chain saw that is modified, damaged, improperly adjusted or maintained, or not completely and securely assembled can lead to a malfunction and increase the risk of serious personal injury or death. - Never operate a chain saw that is modified, damaged, improperly maintained or not completely and securely assembled. - Always check your chain saw for proper condition and operation before starting work, particularly the throttle trigger, throttle trigger lockout, Master Control Lever, front hand guard, chain brake and cutting attachment. - Ensure that the throttle trigger and throttle trigger lockout move freely and always spring back to the idle position when released. The throttle trigger must not engage until the throttle trigger lockout is depressed. The Master Control Lever must move easily to STOP. - Never attempt to modify or override the controls or safety devices in any way. - If your saw or any part is damaged or does not function properly, take it to your authorized STIHL servicing dealer. Do not use the saw until the problem has been corrected. 0458-573-8621-D 13
