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. SAFETY INSTRUCTIONS 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 or engine oil. F Checking wear on cutting equipment Saw chain 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. G Chain drive sprocket The clutch drum is fitted with one of the following drive sprockets: A SPUR (integral drive sprocket) B RIM (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. A B min 4 mm (0,16") A B 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.

A B min 4 mm (0,16") A B SAFETY INSTRUCTIONS H 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. If a hollow forms on one side of the bar tip this is due to a slack chain. • To prolong the life of the bar you should turn it over daily. MOST CHAIN SAW ACCIDENTS HAPPEN WHEN THE CHAIN TOUCHES THE OPERATOR. • WEAR PERSONAL PROTECTIVE EQUIPMENT (see the section on ”Chain saw safety equipment”). • DO NOT TACKLE ANY JOB YOU ARE UNSURE OF (see the section on ”Personal protective equipment”, ”How to avoid kickback”,”General working instructions”and ”Cutting equipment”). • AVOID SITUATIONS WHERE THERE IS A RISK OF KICKBACK (see the section on ”Personal protective equipment”). • USE THE RECOMMENDED PROTECTIVE EQUIPMENT AND CHECK ITS CONDITION (see section on ”General working instructions”). • CHECK THAT ALL SAFETY FUNCTIONS ARE WORKING (see section on ”General working instructions”and ”General safety precautions”). HOW TO AVOID KICKBACK Kickback can happen very suddenly and violently; kicking the saw, bar and chain back at the user. If this happens when the chain is moving it can cause very serious, even fatal injuries. It is vital you understand what causes kickback and that you can avoid it by taking care and using the right working technique. What is kickback? The word kickback is used to describe the sudden reaction that happens when the upper quadrant of the tip of the bar (known as the “kickback zone”) touches an object and the saw is kicked backwards. Kickback always occurs in the cutting plane of the saw. Normally the saw and bar are thrown backwards and upwards towards the user. However the saw may move in a different direc...
