Raise the tip of the guide bar a little and turn the chain tensioning screw (4) to the right (clockwise) until the saw chain is again up against the bottom edge of the guide bar (see circle). While keeping the tip of the guide bar raised, tighten the nuts (2) again with the universal wrench. If kickback occurs due to contact of the guide-bar tip with wood (see SAFETY PRECAUTIONS, page 10), the chain brake will stop the chain through inertia if the kickback is sufficiently strong. The chain brake is installed to block the saw chain before starting it and to stop it immediately in case of an emergency. IMPORTANT: NEVER run the saw with the chain brake activated (except for testing, see "Testing chain brake")!Doing so can very quickly cause extensive engine damage!ALWAYS release the chain brake before starting the work!To engage the chain brake manually, simply push the hand guard (1) forward (towards the tip of the saw) with your left hand (arrow ). Pull the hand guard (1) towards you (arrow 2) until you feel it catch. If the kickback is strong enough the sudden acceleration of the guide bar combined with the inertia of the hand guard (1) will automatically actuate the chain brake. Be especially careful when handling gasoline (petrol).
