Never attempt to modify or disable the chain brake. Never operate a saw if the chain brake has been modified or does not function properly. If you detect a change in the operating characteristics of the chain brake, have your saw serviced immediately by an authorized STIHL servicing dealer. Before starting work, check the operation of the chain brake: ► Run the engine at idle speed. ► Engage the chain brake, 12.1. ► Accelerate up to full throttle for no more than 3 seconds. A properly functioning chain brake prevents the chain from rotating. ► If the chain brake fails to prevent the chain from rotating, have the saw inspected and repaired by an authorized STIHL servicing dealer. 16.2 Testing the Controls Before starting work, confirm that the throttle trig‐ ger lockout (1) and throttle trigger (2) are undam‐ aged and functioning properly. 0458-200-8621-A 2 Throttle Trigger Lockout (1) and Throttle Trig‐ ger (2) WARNING ■ To reduce the risk of serious or fatal injuries, keep hands, feet and other parts of the body away from the chain. Do not touch the saw chain while the engine is running. Never touch a moving chain with your hand or any part of your body, 5.6.3. Keep bystanders out of the area while testing the controls. To test the controls: ► Shut off the engine, 15. ► Attempt to depress the throttle trigger. If the trigger can be depressed without first depressing the throttle trigger lockout, take the chain saw to an authorized STIHL servicing dealer to be repaired before use. Stopping the Engine ► Start the engine, 14. ► Move the Master Control Lever to position . The engine should stop and the Master Con‐ trol Lever should spring back to position when released. ► If the engine does not stop, move the Master Control Lever to position . The engine will stop. ► Take the chain saw to an authorized STIHL servicing dealer to be repaired before use. 16.3 Testing Chain Lubrication WARNING ■ Never operate your saw without bar and chain lubrication. If the chain runs dry, the cutting attachment will be damaged beyond repair within a very short time. A damaged chain may break, resulting in severe or fatal per‐ sonal injury. Always check chain lubrication and the oil level in the tank before starting work and periodically during work. To confirm that the chain oil is flowing properly: 35
