SAFETY INSTRUCTIONS
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.
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.
Chain drive sprocket
The clutch drum is fitted with one of the following drive sprockets:
ASpur sprocket (the chain sprocket is welded on the drum)
BRim 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.
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 daily.

How to avoid kickback
WARNING! Kickback can happen very
!suddenly and violently; kicking the chain saw, bar and chain back at the user. If this happens when the chain is moving it can cause very serious, even fatal injuries. It is vital you understand what causes kickback and that you can avoid it by taking care and using the right working technique.
What is kickback?
The word kickback is used to describe the sudden reaction that causes the chain saw and bar to jump off an object when the upper quadrant of the tip of the bar, known as the kickback zone, touches an object.
