Note: When the dropping cut is made close to the
bridge, the tree should start falling. If it looks like
the tree may possibly not fall in the desired direc-
tion or it leans back and traps the saw chain, stop
the dropping cut and use wedges of wood. plastic or
aluminium to open the cut and to tilt the tree into the
required falling direction.
When the tree starts falling, remove the chainsaw
from the cut, turn it off, put it away and leave the dan-
ger zone via the planned escape route. Look out for
falling branches and do not trip.
• Be alert to signs that the tree is starting to fall:
cracking sounds, widening of the felling cut, or
movement in the upper branches.
• To avoid injury, do not cut down a partially felled
tree with your saw. Pay special attention to par-
tially felled trees that may be poorly supported.
If a tree does not fall completely, set the saw aside
and pull with a cable winch, block and tackle, or
tractor.
Sawing a felled tree (bucking)
The term "buck" means to cut a felled tree trunk into
the desired log length.
Caution: Do not stand on the log while it is being cut.
Any portion can roll, and you may lose your footing
and control over the device. Never run the saw on
sloping ground. Make sure you have secure footing
and distribute your body weight evenly on both feet. If
possible, put branches, beams or wedges under the
tree to support it.
Important Notes
• Always only cut one log at a time.
• Be careful when cutting splintery wood. You could
be hit by sharp wood particles.
• Cut small logs or branches on a sawhorse. When
cutting logs, another person should hold the trunk.
Do not secure the trunk with your leg or foot.
• If you use the saw in places where trunks and roots
are tangled, drag the logs into a clear spot, and lift
the cleared logs first.
Different cuts for bucking (Fig. D)
Caution: If the saw is clamped into a log, do not
pull it out by force. You risk losing control of the de-
vice, thereby resulting in injury and / or damage to
the saw. Hold the saw, and drive a plastic or wood
- wedge into the cut until the saw can be pulled out
easily. Position the saw carefully and allow it to cut
again. Start the saw if it is trapped in a trunk.
Upper section (Fig. E, item 1)
Position the saw at the upper end of the log. With the
overcut apply only slight downward pressure.

Sub-section (Fig. E, item 2)
Place the undercut at the bottom of the trunk, hold-
ing the top of the saw down against the log. Practice
the undercut; it is just as easy to train from the top.
Hold the saw firmly and maintain control. The saw
will push backwards (towards you).
Caution: Never hold the saw upside down for an un-
dercut. In this position, you have no control over the
device. Always execute the first cut on the compres-
sion side of the log. The compression side of a log
is where the pressure of the root weight is concen-
trated.
Bucking without supports (Fig. F)
• When the whole length of the tree trunk is stable
and even, start sawing from the top (No. 1).
• Make sure you do not saw into the ground.
Trunk cutting, supported on one end (Fig. G)
• When the tree trunk is propped up on one end,
make the first cut (No. 1) from underneath (1/3 of
the trunk diameter) in order to prevent splitting.
• The second cut is made from the top (2/3 of the
diameter) in the same line as the first cut to prevent
the saw from becoming jammed.
Trunk cutting, supported on both ends (Fig. H)
• When the tree trunk is propped up on both ends,
make the first cut (No. 1) from the top (1/3 of the
trunk diameter) in order to prevent splitting.
• The second cut is made from underneath (2/3 of
the diameter) in the same line as the first cut to
prevent the saw from becoming jammed.
Limbing and Trimming
Attention: Always pay attention to, and protect your-
self against kickback. Never let the moving chain at
the top of the guide bar come into contact with other
branches or objects when limbing or trimming. Such
contact can cause serious injury.
Attention: Climb the tree for pruning or trimming. Do
not stand on ladders, platforms, etc. as you may lose
your balance and lose control of the device.
Important Notes
• Work slowly, and hold the saw firmly with both
hands. Ensure safe standing position and balance.
• Watch out for spring backs. Use extreme caution
when cutting small size limbs. Pliable material may
catch in the saw chain and be whipped toward you
or pull you off balance.
• Watch out for spring backs. This is especially true
for branches that are bent or under pressure. Avoid
coming in contact with the branch or the saw when
there is tension in the wood.
• Keep your work area clear. Keep the path clear of
branches to avoid tripping over them.
