Resumen del manual
If the chain lubrication system is still not working after carrying out the above checks and associated measures you should contact your servicing dealer. Chain drive sprocket The clutch drum is fitted with one of the following drive sprockets: A Spur sprocket (the chain sprocket is welded on the drum) B Rim sprocket (replaceable) Regularly check the degree of wear on the drive sprocket. Replace if wear is excessive. Replace the drive sprocket whenever you replace the chain. Needle bearing lubrication Both versions of sprockets have a needle bearing on the drive shaft, which has to be greased regularly (once a week). CAUTION! Use only high quality bearing grease or engine oil. Checking wear on cutting equipment Check the chain daily for: • Visible cracks in rivets and links. • Whether the chain is stiff. • Whether rivets and links are badly worn. Replace the saw chain if it exhibits any of the points above. We recommend you compare the existing chain with a new chain to decide how badly the existing chain is worn. When the length of the cutting teeth has worn down to only 0.16 inch (4 mm) the chain must be replaced. 14 – English GENERAL SAFETY PRECAUTIONS Bar Check regularly: • Whether there are burrs on the edges of the bar. Remove these with a file if necessary. • Whether the groove in the bar has become badly worn. Replace the bar if necessary. • Whether the tip of the bar is uneven or badly worn.
