GENERAL SAFETY PRECAUTIONS
English – 15
Checking chain lubrication
• Check the chain lubrication each time you refuel. See
instructions under the heading Lubricating the bar tip
sprocket.
Aim the tip of the bar at a light coloured surface about
20 cm (8 inches) 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:
• 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 your service agent.
Chain drive sprocket
The clutch drum is fitted with following drive sprockets:
A 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.
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 4 mm the chain must be replaced.
Guide 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.
