1. When ready to start cutting,
release the brake, by pulling
the chain brake back firmly
towards the rear of the
chainsaw.
2. Depress throttle safety
release (a), then depress
throttle trigger (b). The chain
will now be running, ready to
make a cut.
3. Press the bucking spikes
against the timber ensuring
the chain is not making
contact with the material
being cut.
4. Keep the bucking
spikes touching the
wood you are cutting.
Due to the rotation of
the chain, it will pull
the saw into the wood.
When the bucking
spikes are touching
the timber, it will help
prevent any sudden
jerking or kick-back.
5. Withdraw the chainsaw from the cut while the chain is still
running.

Hints and Tips
•
Do not force the saw into the cut. Apply only light pressure
whilst running the engine at full throttle.
• If the saw chain gets caught in the cut, do not try to remove it
by twisting the guide or pulling forcibly. Use a lever or wedge
to open up the cut so that the saw chain is freed.
• Run the chainsaw motor at full revs. This makes the job safer,
as there is less chance of pull-in or kick-back.
• Position your body to the left of the chainsaw so if it kicks
back uncontrollably, it goes over your right shoulder, never
stand in the cutting line of the saw.
• Keep a firm grip with your left hand on the front handle, with
your thumb securely below the handle.

Bucking is cutting a log into lengths
for easier handling. To saw a log lying
on the ground, first saw halfway, then
roll the log over and cut from the
opposite side.
To saw the end of a log supported
off the ground, first saw up from the
bottom one-third through the log then
finish by sawing down from the top.
To saw a log in the middle of two
supports holding it off the ground, first saw down from the top
one-third through the log then finish by sawing up from the
bottom.
Limbing is the process of
removing the branches from a
fallen tree. Check the direction
in which a branch will bend
before cutting it. Always cut on
the opposite side to the bending
direction so that the guide bar is
not pinched in the cut. For large limbs that cannot be removed
in one cut, make an initial cut from the bent side and finish by
sawing from the opposite direction. Do not remove limbs that
are supporting the fallen tree on the ground until the tree has
been cut into lengths.
Felling a tree
Decide the direction in which you
wish the tree to fall, taking into
account the direction of the wind,
the position of branches, lean
of the tree, ease of subsequent
limbing and bucking and other
factors prevalent at the time.

WARNING!
FELLING A TREE SHOULD ONLY BE
DONE BY TRAINED OPERATORS.
WARNING!
ALWAYS KEEP A BALANCED STANCE.
DO NOT STAND ON THE LOG. BE ALERT TO
THE FACT THAT THE LOG MAY ROLL OVER. WHEN
WORKING ON A SLOPE, ALWAYS STAND ON THE UP
HILL SIDE OF THE LOG.
WARNING!
AVOID CUTTING INTO THE GROUND
AS THIS WILL VERY QUICKLY DULL THE SAW
CHAIN.
