Mounting the guide bar and saw chain Put the electric chain saw on a stable surface and carry out the following operations for mounting the bar and chain: Release chain brake. To do this, pull the hand guard (1) in thedirection of the arrow. Flip up the sprocket guard quick tightener (2) (see also Fig. G). Push in the sprocket guard quick tightener firmly against spring pressure, and slowly turn it counter-clockwise until you feel it engage. Keep pushing in, and turn it as far as possible counter-clockwise. Release the sprocket guard quick tightener (remove pressure) and now turn it clockwise to its original position. Repeat this procedure until the sprocket guard (3) is unscrewed. Pull the sprocket guard (3) up slightly, pull out of the rear fittings (4) and remove. A B C D Place the saw chain (9) on the sprocket (6). Using your right hand, guide the saw chain into the upper guide groove (8) of the guide bar. The cutting edges of the saw chain on the top of the guide bar must point in the direction of the arrow! PUTTING INTO OPERATION CAUTION: When working on the guide bar or saw chain always wear protective gloves and pull out the power supply plug. CAUTION: Switch on the electric chain saw only after having assembled it completely and inspected! 123476 13 3 F Line up the hole in the sprocket guard with the threaded pin (11). Turn the chain tensioning screw (H/14) to align the chain tensioning pin (12) with the hole in the guide bar. Using your left hand, lightly press the guide bar against the holder on the housing and guide the saw chain (9) around the nose sprocket (10) on the guide bar. While doing this, pull the saw chain slightly in the direction shown by the arrow. E H Tightening the saw chain Firmly push in and simultaneously turn the sprocket guard quick tightener (2, clockwise) in order to screw on the sprocket guard (3), but do not tighten it yet. Lift the tip of the guide bar slightly and turn the chain tensioner (14) clockwise until the saw chain engages in the guide groove on the lower side of the guide bar (see the circle). Push in the sprocket guard quick tightener (2) again and tighten by turning clockwise. Release the sprocket guard quick tightener (2) (remove pressure) until it turns freely, then fold it in as shown in the illustration. 9 10 14 2 2 11 3 12 G First press the sprocket guard (3) into the mounting (13) and then push it onto the threaded pin (F/11). SERVICE K I J Checking the chain tension The chain has the proper tension when it lies against the bottom edge of the guide bar and can be easily pulled by hand about 2-4 mm (about 1/8") up from the guide bar. Check the chain tension frequently - new chains tend to get longer during use! When checking the chain tension the motor must be switched off and the power supply plug pulled out. If the chain is too loose: Loosen the sprocket guard quick tightener by about a quarter turn. Tighten the chain as described under “Tighteneing the saw chain.” HINT: Use 2 or 3 saw chains alternately for even wear of the chains, sprocket and guide bar running surfaces. In order to guarantee a uniform wear of the groove in the bar the bar should be turned over whenever replacing the chain. Chain brake The electric chain saw comes with an chain brake as standard equipment. Kickback occurs due to contact of the guide bar tip with wood (see SAFETY PRECAUTIONS, page 5). Run-out brake The electric chain saw come with a run-out brake as standard equipment. The run-out brake ensures that the chain comes to a stop immediately when the ON/OFF switch is released, thus preventing the chain from continuing to run and presenting a hazard. Testing of the run-out brake is described on page 14. Chain and run-out brake maintenance The brake systems are very important safety features, and like any other part they are subject to a certain amount of wear. Regular inspection and maintenance is important for your personal safety, and can be properly performed only by a DOLMAR service center. Engaging the chain brake (braking) 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. To engage the chain brake manually, simply push the hand guard (1) forward (towards the tip of the saw) with your left hand (arrow 2). Releasing the chain brake Pull the hand guard (1) towards you (arrow 3) until you feel it catch. The brake is now released. Note: When the chain brake is actuated the power supply to the motor will be cut off. Testing of the chain brake is described on page 14. 231 Saw chain oil Saw chain oil Use a special oil with adhesive addition for lubricating the saw chain and bar. The adhesive addition prevents that the oil is centrifuged too fast from the sawing device. Do not use mineral oils. In order to protect the invironment the use of biologically decomposeable oil is prescribed. The saw chain oil sold by DOLMAR, called BIOTOP, is made of special vegetable...
