7 Take great care when cutting a tree that is under tension.
A tree that is under tension may spring back to its normal
position before or after being cut. If you position yourself
incorrectly or make the cut in the wrong place the tree may
hit you or the machine and cause you to lose control. Both
situations can cause serious personal injury.
8 Before moving your chain saw switch off the engine and
lock the chain using the chain brake. Carry the chain saw
with the bar and chain pointing backwards. Fit a guard to
the bar before transporting the chain saw or carrying it for
any distance.
9 When you put the chain saw on the ground, lock the saw
chain using the chain brake and ensure you have a
constant view of the machine. Switch the engine off before
leaving your chain saw for any length of time.
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 minimizes the effect of kickback and lets
you keep the chain saw under control.
3 A single-handed grip may be used, but only by persons
who are trained and have knowledge of tree maintenance
work using a chain saw, both above and on the ground. Do
not let go of the handles!
4 Most kickback accidents happen during limbing. Make
sure you are standing firmly and that there is nothing in
the way that might make you trip or lose your balance.

WORKING TECHNIQUES
Lack of concentration can lead to kickback if the kickback
zone of the bar accidentally touches a branch, nearby tree
or some other object.
Have control over the workpiece. If the pieces you intend
to cut are small and light, they can jam in the saw chain
and be thrown towards you. Even if this does not need to
be a danger, you may be surprised and lose control of the
saw. Never saw stacked logs or branches without first
separating them. Only saw one log or one piece at a time.
Remove the cut pieces to keep your working area safe.
5 Never use the chain saw above shoulder height and
avoid cutting with the tip of the bar. Never use the
chain saw one-handed!
6 Always use a fast cutting speed, i.e. full throttle.
7 If you have to cut branches or the like that are above
shoulder height, a working platform or scaffold tower is
recommended.
8 Take great care when you cut with the top edge of the bar,
i.e. when cutting from the underside of the object. This is
known as cutting with a pushing chain. The chain tries to
push the chain saw back towards the user. If the saw chain
is jamming, the saw may be pushed back at you.
