GENERAL SAFETY PRECAUTIONS
16 – English
1155548-32 Rev.1 2013-06-28
Filling with chain oil
•
All our chain saws have an automatic chain lubrication
system. On some models the oil flow is also
adjustable.
•
The saw chain oil tank and the fuel tank are designed
so that the fuel runs out before the saw chain oil.
However, this safety feature requires that you use the
right sort of chain oil (if the oil is too thin it will run out
before the fuel), and that you adjust the carburetor as
recommended (a weak mixture may mean that the
fuel lasts longer than the oil) and that you also use the
recommended cutting equipment (a bar that is too
long will use more chain oil). The above conditions
also apply to chain saw models with an adjustable oil
pump.
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 servicing dealer.
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.
