(No. 3), saw only to a depth so that a bridge (No. 4) (holding
wood) remains which can act as a hinge. The bridge prevents
the tree from turning and falling in the wrong direction. Do not
cut through the bridge.
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 direction 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 danger 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 partially 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 device, 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, holding 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 undercut. In
this position, you have no control over the device. Always
execute the first cut on the compression side of the log.
The compression side of a log is where the pressure of the
root weight is concentrated.
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 yourself
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.
Lopping (Fig.J)
• Lopping means removing branches from the felled tree.
• Leave the larger limbs that are underneath the felled tree,
and use them as support while you continue to work.
• Start at the base of the felled tree and work your way up
to the top. Remove smaller parts of the tree with a cut in
the direction of growth (arrows Fig. J).
• Be sure to keep the tree between you and the saw.
• Remove larger, supporting branches using the methods
in the section „Bucking without restraints“.
• Always cut branches under tension from the underneath
to the top, so the saw does not become trapped.
• Always cut small and freely hanging limbs with one cut.
By undercutting they could fall in and pinch the saw.
Trimming (Fig. I)
Attention : Leave stubs in branches or below cut them to
shoulder level only. Never cut branches above shoulder
height. Leave such work to an expert.
