GENERAL SAFETY PRECAUTIONS

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 4 mm (5/32") 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 regularly.

WARNING! Most chain saw accidents

!happen when the chain touches the operator.

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.
