SAFETY INSTRUCTIONS
•Check that the bar tip sprocket turns freely and that the lubricating hole in the tip sprocket is not blocked. Clean and lubricate if necessary.
If the chain lubrication system is still not working after carrying out the above checks and associated measures you should contact your service agent.
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.
Needle bearing lubrication
The clutch drum is fitted with one of the following drive sprockets:
ASpur sprocket (the chain sprocket is welded on the drum)
BRim sprocket (replaceable)
Both versions have a needle bearing on the drive shaft, which has to be greased regularly (once a week). CAUTION! Use a
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.
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 4 mm the chain must be replaced.
Chain drive sprocket
The clutch drum is fitted with one of the following drive sprockets:
ASpur sprocket (the chain sprocket is welded on the drum)
BRim 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.
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 the underside of the bar tip this is due to running with a slack chain.
•To prolong the life of the bar you should turn it over daily.
