If the chain lubrication is not working:
•
Check that the oil channel in the bar is not obstructed.
Clean if necessary.
•
Check that the groove in the edge of the bar is clean.
Clean if necessary.
•
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 our Customer Support Department.
Chain drive sprocket
The clutch drum is fitted with the following drive sprocket:
Spur sprocket (the chain sprocket is welded on the drum)
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).
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
4mm (0.16 inchs) the chain must be replaced.
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.
