23CAUTION:Before doing any work on the guide bar or chain,always switch off the engine and pull the plug capoff the spark plug (see 7‑6 “Replacing the sparkplug”). Always wear protective gloves!CAUTION:Start the petrol chain saw only after havingassembled it completely and inspected.6c-1. Mounting the guide bar and saw chain(Fig. 41)Place the saw on a stable surface and perform the followingwork steps in order to install the guide bar and saw chain:Release the chain brake by pulling the hand guard (1) indirection of arrow.Fold up the sprocket guard quick tensioner (2) (see also theillustration on tensioning the saw chain).Push the sprocket guard quick tensioner in forcefully againstthe spring tension and slowly turn counter-clockwise, untilyou feel it engage. Keep pushing, and turn as far as possiblecounter‑clockwise.Release the sprocket guard quick tensioner again and turnclockwise to bring it back to its original position. Repeat thisprocedure until the sprocket guard (4) is unscrewed.Remove the sprocket guard (4).(Fig. 42)Put the guide bar (5) on and push it against the sprocket (6).(Fig. 43)Lift the chain (8) over the sprocket (7).Guide the chain from above about halfway into the groove (9)on the guide bar.CAUTION:Note that the cutting edges along the top of the chain mustpoint in the direction of the arrow!(Fig. 44)Pull the chain (8) around the sprocket nose (10) of the guidebar in the direction of the arrow.(Fig. 45)Align hole on sprocket guard (4) with the pin (11).Turn the chain tensioner (3, see 6c‑2 “Tightening the sawchain”) to bring the chain tensioner pin (12) into alignmentwith the hole in the guide bar.Push the sprocket guard (4) onto the pin (11).6c-2. Tightening the saw chain(Fig. 46)Simultaneously push in hard on the sprocket guard quicktensioner (2) and turn it clockwise to screw the sprocketguard on, but do not yet tighten it.Raise the tip of the guide bar slightly and turn the chaintensioner (3) clockwise until the saw chain is flush against thebottom of the guide bar (see circle).Push the sprocket guard quick tensioner (2) in again andtighten by turning clockwise.(Fig. 47)Release the sprocket guard chain tensioner until it turnsfreely, then fold it in between protective ribs (15) as shown inthe illustration.6c-3. Checking the chain tension(Fig. 48)The tension of the chain is correct if the chain rests againstthe bottom side of the guide bar and can still be easily turnedby hand.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 beswitched off.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.6c-4. Retensioning the saw chain(Fig. 49)All that is necessary to retension the saw chain is to loosenthe quick tensioner (2) slightly as described under “Mountingthe guide bar and saw chain”.Tension the chain as already described.6c.
