SAFETY INSTRUCTIONS
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
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.
Kickback always occurs in the cutting plane of the bar.
Normally the chain saw and bar are thrown backwards and
upwards towards the user. However, the chain saw may move
in a different direction depending on the way it was being used
when the kickback zone of the bar touched the object.
Kickback only occurs if the kickback zone of the bar touches
an object.
General rules
1 If you understand what kickback is and how it happens
then you can reduce or eliminate the element of surprise.
By being prepared you reduce the risk. Kickback is usually
quite mild, but it can sometimes be very sudden and
violent.
2 Always hold the chain saw firmly with your right hand on
the rear handle and your left hand on the front handle.
Wrap your fingers and thumbs around the handles. You
should use this grip whether you are right-handed or left-
handed. This grip minimises the effect of kickback and lets
you keep the chain saw under control.
!
WARNING! Most chain saw accidents
happen when the chain touches the
operator.

instructions under the heading Personal
protective equipment.

not adequately trained for. See instructions

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.
