GENERAL SAFETY PRECAUTIONS

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.
See instructions under the heading Maintenance, Needle
bearing lubrication.
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.
File all the teeth to the same length. When the length of
the cutting teeth is reduced to 5/32 inch (4 mm) the chain
is worn out and should 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.
!
WARNING! Most chain saw accidents
happen when the chain touches the
