GENERAL SAFETY PRECAUTIONS
14 – English
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) a
way. 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 necessar
y.
• Check that the groove in the edge of the bar is clean.
Clean if necessar
y.
• Check that the bar tip sprocket turns freely and that
the lubr
icating hole in the tip sprocket is not blocked.
Clean and lubricate if necessary.
If the chain lubrication system is still not working after
carr
ying out the above checks and associated measures
you should contact your service agent.
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 w
ear 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 a high-quality bearing grease or
engine oil.
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
abo
ve.
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.
