This line should be perfectly horizontal and at right angles (90°) to the chosen felling direction. SAFETY INSTRUCTIONS We recommend that you use a bar that is longer than the diameter of the tree, so that you can make the FELLING CUT and DIRECTIONAL CUT with single cutting stokes. (See ”Technical data” to find out which lengths of bar are recommended for your saw). There are methods for felling trees with a diameter larger than the bar length. However these methods involve a much greater risk that the kickback zone of the bar will come into contact with the tree. UNLESS YOU HAVE SPECIAL TRAINING WE ADVISE YOU NOT TO FELL TREES WITH A DIAMETER LARGER THAN THE BAR LENGTH OF YOUR SAW! E Limbing MOST KICKBACK ACCIDENTS HAPPEN DURING LIMBING!PAY CLOSE ATTENTION TO THE POSITION OF THE KICKBACK ZONE OF THE BAR WHEN YOU ARE LIMBING BRANCHES THAT ARE IN TENSION! Make sure there are no obstacles in your way. Work on the left side of the trunk. Work close to the saw for maximum control. If possible, let the weight of the saw rest on the trunk. Keep the tree between you and the saw as you move along the trunk. F Cutting the trunk into logs See chapter ”General working instructions” point 2 ”Basic cutting technique”. 4 Freeing a tree that has fallen badly = high accident risk A Freeing a “Trapped tree” The safest method is to use a winch. A Tractor-mounted B Portable B Cutting trees and branches that are in tension Preparations: a) Work out which way the tree or branch will move if released and where the natural “BREAKING POINT” is (i.e. the place it would break if it was bent even more). b) Decide which is the SAFEST way to release the tension and whether YOU are able to do it safely. In complicated situations the only safe method is to put aside your chain saw and use a winch. General advice: a) Position yourself so that you will be clear of the tree or branch when it springs free. b) Make one or more cuts at or near the BREAKING POINT. Make as many cuts of sufficient depth as necessary to reduce the tension and make the tree or branch break at the BREAKING POINT. Never cut straight through a tree or branch that is in tension!

Check that the chain brake is in disengaged position by moving the front hand guard towards the front handle. Take off the bar nuts and remove the clutch cover. Take off the transportation ring (A). ASSEMBLY Hold up the tip of the bar and tighten the chain. The chain is correctly tensioned when there is no slack on the underside of the bar, but it can still be turned easily by hand. Hold up the bar tip and tighten the bar nuts with the combination wrench. When fitting a new chain, the chain tension has to be checked frequently until the chain is run-in. Check the chain tension regularly. A correctly tensioned chain gives good cutting performance and long lifetime. A Fit the bar over the bar bolts. Place the bar in its rearmost position. Place the chain over the drive sprocket and in the groove on the bar. Begin on the top side of the bar. Make sure that the edges on the cutting links are facing forward on the top side of the bar. Fit the clutch cover and locate the chain adjuster pin in the hole on the bar. Check that the drive links of the chain fit correctly on the drive sprocket and that the chain is in the groove on the bar. Tighten the bar nuts finger tight. Tension the chain by using the combination wrench. Turn the chain adjuster screw clockwise. The chain should be tensioned until it fits snugly on the underside of the bar. FUEL HANDLING Fuelmix IMPORTANT! The chain saw is equipped with a two-stroke engine and must always been run using a mixture of gasoline and two-stroke engine oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture....
