[. . . ] Check that the starter pulley can be turned at least half a turn, when the starter cord is entirely pulled out. J I 1Changing the broken recoil spring Lift the starter pulley. The recoil spring is disassembled from the starter device, with its inside facing down. Put a new recoil spring in the right position, If the spring pops out when assembling, it should be mounted again, out and in towards the centre. Assemble the starter pulley, and tension the recoil spring. /’ ‘>’ , , . /, — /. , / IStarter device assembly IAssemble the starter device, by ~ulling the starter cord out first, then place the starter against the crankcase. Then slowly release the starter cord so that the pulley engages with the pawls. Assemble and tighten the screws, which hold the starter. 1 , Chain maintenance Chain maintenance safety For the personal safety, it is of great importance, that the bar and chain combinations of so called low kick type are used and that the cutting equipment is maintained correctly. Important notes: Chain tension Sharpening Lubrication Check - maintenance q q q q Recommended cutting equipment for Husqvarna chain saws Following is a list of recommended cutting equipment for saws below 3. 8 cu. The combinations of powerhead, bar and chain have been investigated in accordance with the kickback requirements of ANSI B 175. 1. The guide bar nose radius is determined by either the maximum number of teeth in the nose sprocket or the corresponding maximum nose radius of a solid bar. There may be other combinations available, which will also achieve kickback protection. As we are listing the maximum guide bar nose radius, you may use a guide bar with smaller nose radius then in our list. For guide bars of the same length, all sprocket-nose guide bars of the same pich and having the same number of sprocket teeth may be considered to have equivalent kickback energy. A hard nose bar having the same length and nose radius as a sprocket-nose bar may be considered to have equivalent or less kickback energy then the sprocket-nose bar. Low kickback saw chain is a chain which has met the kickback performance requirements of ANSI B 175. 1 safety requirements for gasoline-powered chainsaws when tested on the representative sample of chain saws below 3. 8 cu. in. specified in ANSI B 175. 1 These are marked with an asterix X in the table below. We recommend that you as replacement use the listed chains or “Low kickback saw chains” which are available at your dealer. NOTE: The second number in the Oregon part number indicate the thickness of the drive link. You are free to choose between 0. 050” and 0. 058” drive link for the corresponding bar.

Chain tension should be checked frequently during work and corrected if necessary. Make sure that the engine is shut off. I 1 Tension the chain as tight as possible, but so it can still be pulled easily along the bar by hand. [. . . ] They can spring back towards you and cause loss of control resulting in injury. ! 19 Ill Generalworking instruction Basic rules for felling trees Normally the felling consists of two main cutting operations notching and making the felling cut. Notching Start making the upper notch cut on the side of the three facing the felling direction. Look through the kerf as you saw the lower cut so you do not saw too deep into the trunk. The notch should be deep enough to create a hinge of sufficient width and strength. [. . . ]
