12STOP24121CBAEngaging the chain brake (braking)If the kickback is strong enough the sudden acceleration of theguide bar combined with the inertia of the hand guard (1) willautomatically actuate the chain brake.To engage the chain brake manually, simply push the handguard (1) forward (towards the tip of the saw) with your lefthand (arrow 1).Releasing the chain brakePull the hand guard (1) towards you (arrow 2) until you feel itcatch. The brake is now released.Chain brakeThe DCS4600 / DCS5000 / DCS5001 comes with an inertiachain brake as standard equipment. If kickback occurs due tocontact of the guide-bar tip with wood (see SAFETY PRECAU-TIONS, page 6), the chain brake will stop the chain throughinertia if the kickback is sufficiently strong.The chain will stop within a fraction of a second.The chain brake is installed to block the saw chainbefore starting it and to stop it immediately in case of anemergency.IMPORTANT: NEVER run the saw with the chain brakeactivated (except for testing, see ìTesting chain brakeî)!Doing so can very quickly cause extensive engine dama-ge!ALWAYS release the chain brakebefore starting the saw!Checking the chain tensionThe tension of the chain is correct if the chain rests against thebottom side of the guide bar and can still be easily turned byhand.While doing so the chain brake must be released.Check the chain tension frequently - new chains tend to getlonger during use!When checking the chain tension the engine must be switchedoff.NOTE:It is recommended to use 2-3 chains alternatively.In order to guarantee uniform wear of the guide bar the barshould be turned over whenever replacing the chain.Retightening the saw chainLoosen the nuts (2) about one turn with the universalwrench. Raise the tip of the guide bar a little and turn the chaintensioning screw (4) to the right (clockwise) until the saw chainis again up against the bottom edge of the guide bar (seecircle).While keeping the tip of the guide bar raised, tighten the nuts(2) again with the universal wrench.
