Check that the chain catcher and the right hand guard are in correct condition without any visible faults such as damaged material. Every 2-3 hours of use Control the bar condition, if necessary clean the lubrication holes(fig.4) and the guide grooves(fig.5) carefully; If the groove is worn or shows signs of deep notching, it must be replaced. Turn the bar to ensure even wear(fig.6). Clean the pinion regularly and check that it has not been subject to excess wear(fig.7). Lubricate the nose sprocket with bearing grease through the hole shown in the illustration (fig.8). Chain sharpening (When necessary) If the chain does not cut correctly, or requires hard bar pressure against the wood, and if the sawdust is very fine, this is a sign that it is not sharpened correctly. If the cutting action produces no sawdust, this means the cutting edge has been worn completely and the chain is pulverising the wood during cutting. A well-sharpened chain crosses through the wood without effort or pressure and produces large long wood shavings. The cutting side of the chain is composed of the cutting link (fig.9) with a cutting tooth(fig.10) and a cutting limit gauge(fig.11). The difference between these determines the cutting depth; a file guide and a 4mm diameter round file are needed to obtain good sharpening results; Follow the instructions below: Once the chain has been mounted and the tension is correctly adjusted, and the chain brake is activated, position the file guide perpendicular to the bar as shown in the illustration(fig.12), filing the cutting teeth at the angle shown(fig.13), always working from the interior towards the exterior, lessening the pressure during the return stage (it is very important to follow the instructions perfectly: excessive or insufficient sharpening angles, or an incorrect file diameter will increase the risk of kickback.) To obtain higher precision on side angles, it is advisable to position the file so that it exceeds the upper cutter by about 0.5 mm. File all the teeth on one side first, then turn the machine over and repeat the operation. Make sure that after sharpening operations, all teeth are the same length and that the height of the depth gauge is 0.6 mm lower than the upper cutter: check the height using a proper template and file (with a flat file) all protruding parts, rounding off the front part of the depth gauge(fig.14), paying attention to not file the kickback protection tooth(fig.15) Every 30 hours use. Take the machine to the Authorised Service Centre for general revision and control check on brake components. PERIODS OF PROLONGED DISUSE Always empty the fuel tank with the same precautions used in filling it. H. CUTTING TECHNIQUES 1,2,3,4,5,6,7,8,9,10,11,12,13,14 When using the machine, prevent: (fig.1) -cutting in conditions where the trunk could split during cutting (wood under pressure, dry dead trees, etc): sudden splitting can be very dangerous. -the bar or the chain from becoming blocked in the cutting notch: if this should occur, disconnect the machine from the main electricity supply and try to raise the trunk using an appropriate tool as a lever; do not attempt to free the machine by shaking or pulling as this could cause damage or injury. -situations that can lead to kickback reactions. During machine use: (fig.1) - Whe...
