GENERAL SAFETY PRECAUTIONS
Chain drive sprocket
Bar
Check regularly:
The clutch drum is fitted with one of the following drive
sprockets:
•
Whether there are burrs on the edges of the bar.
Remove these with a file if necessary.
A
Spur sprocket (the chain sprocket is welded on the
drum)
B
Rim sprocket (replaceable)
•
•
Whether the groove in the bar has become badly
worn. Replace the bar if necessary.
Regularly check the degree of wear on the drive sprocket.
Replace if wear is excessive. Replace the drive sprocket
whenever you replace the chain.
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.
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.
•
To prolong the life of the bar you should turn it over
regularly.
See instructions under the heading Maintenance, Needle
bearing lubrication.
Checking wear on cutting equipment
WARNING! Most chain saw accidents
happen when the chain touches the
operator.
!
Check the chain daily for:
Wear personal protective equipment. See
instructions under the heading Personal
protective equipment.
Do not tackle any job that you feel you
are not adequately trained for. See
instructions under the headings
Personal protective equipment, How to
avoid kickback, Cutting equipment and
General working instructions.
•
•
•
Visible cracks in rivets and links.
Whether the chain is stiff.
Whether rivets and links are badly worn.
Avoid situations where there is a risk of
kickback. See instructions under the
heading Machine′s safety equipment.
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.
Use the recommended protective
equipment and check its condition. See
instructions under the heading General
working instructions.
When the length of the cutting teeth has worn down to
only 0.16 inch (4 mm) the chain must be replaced.
Check that all the chain saw safety features
are working. See instructions under the
headings General working instructions and
General safety precautions.
