We recommend that you adjust the raker clearance every third time you sharpen the chain. NOTE! This recommendation assumes that the length of the cutting teeth is not reduced excessively. • To adjust the raker clearance you will need a FLAT FILE and a RAKER GAUGE. • Place the gauge over the raker lip. • Place the file over the part of the lip that protrudes through the gauge and file off the excess. The clearance is correct when you no longer feel any resistance as you draw the file over the gauge. 3 Tensioning the chain A slack chain may jump off and cause serious or even fatal injury. • The more you use a chain the longer it becomes. It is therefore important to adjust the chain regularly to take up the slack. • Check the chain tension every time you refuel. NOTE! A new saw chain has a running-in period during which you should check the tension more frequently. • Tension the chain as tightly as possible, but not so tight that you cannot pull it round freely by hand. English – 13 SAFETY INSTRUCTIONS 1 Undo the bar nuts that hold the clutch cover and chain brake, using the combination spanner. Then tighten the nuts by hand as tight as you can. 2 Raise the tip of the bar and stretch the chain by tightening the chain tensioning screw using the combination spanner. Tighten the chain until it not hang slack on the underside of the bar. 3 Use the combination spanner to tighten the bar nuts while lifting the tip of the bar at the same time. Check that you can pull the chain round freely by hand and that it is not slack on the bottom of the bar. The position of the chain tensioning screw varies from model to model. See the”What is what”section to find out where it is on your saw. 4 Lubricating cutting equipment Poor lubrication of cutting equipment may cause the chain to snap and lead to serious, even fatal injuries. A Chain oil • Chainsaw chain oil must demonstrate good adhesion to the chain and also maintain its flow caracteristics regardless of whether it is warm summer or cold winter weather. • As a chainsaw manufacturer we have developed an optimal chain oil which has a vegetable oil base. We recommend the use of our own oil for both maximum chain life and to minimise environmental damage. • If our own chain oil is not available, standard chain oil is recommended. • In areas where oil specifically for lubrication of saw chains is unavailable, ordinary EP 90 transmission oil may be used. • Never use waste oil! This is dangerous for yourself, the saw and the environment. B Filling with chain oil • All our chain saws have an automatic chain lubrication system. On some models the oil flow is also adjustable. • The sizes of the chain oil tank and fuel tank have been chosen so that the saw will run out of fuel before running out of oil. This means that you should never run with a dry chain. However, this safety feature requires that you use the right sort of chain oil (if the oil is too thin it will run out before the fuel), and that you adjust the carburetor as recommended (a weak mixture may mean that the fuel lasts longer than the oil). You should also use the recommended cutting equipment (a bar that is too long will use more chain oil). The above conditions also apply to models with an adjustable oil pump. 14 – English SAFETY INSTRUCTIONS C Checking chain lubrication • Check the chain lubrication each time you refuel. Aim the tip of the saw at a light coloured surface about 20 cm away. After 1 minute running at 3/4 throttle you should see a distinct line of oil on the light surface. If the chain lubrication is not working: 1 Check that the oil channel in the bar is not obstructed. Clean if necessary. 2 Check that the groove in the edge of the bar is clean. Clean if necessary. 3 Check that the bar tip sprocket turns freely and that the lubricating hole in the tip is not blocked. Clean and lubricate if necessary. If the chain lubrication system is still not working after carrying out the above measures you should contact your service agent. D Lubricating the bar tip sprocket • Lubricate the bar tip sprocket each time you refuel. Use the special grease gun and a good quality bearing grease. E Needle bearing maintenance The clutch drum is equipped with one of the following chain sprockets: • Spur sprocket (A) (the chain sprocket is welded on the drum) • Rim sprocket (B) (exchangeable) Both versions have built-in needle bearing at the drive shaft, whitch has to be greased regularly (once a week). NOTE! Use only high quality bearing grease. F Checking wear on cutting equipment Saw chain A B Check the saw chain daily for: • Visible cracks in rivets and links. • Whether the chain is stiff. • Whether rivets and links are badly worn. We recommend you compare the existing chain with a new chain to decide how badly it is worn. When the length of the cutting teeth has worn down to only 4 mm the chain must be replaced.
