Undercut and felling of the tree (Fig. B - C)
Saw a wedge with a depth of 1/3 of the tree diameter at a right-angle to the falling direction. Make the lower
horizontal wedge cut fi rst (Fig. B, No. 1).
This will prevent the saw chain or the guide bar becoming jammed when the second wedge cut (Fig. B, No.
2) is made. Now remove the excised wedge.
Next, you can run the felling cut (Fig. B, Pos. 3) on the opposite side of the tree. Do this at approximately 5 cm
above the centre of the notch. Make the dropping cut parallel to the horizontal wedge cut. For the dropping
cut (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 slop-
ing 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 fi rst.
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.
