Cutting Techniques

30
When using the machine, prevent:
- cutting in conditions where the trunk could split during cutting
(wood under pressure, dry dead trees, etc): sudden splitting
can be very dangerous.
- the bar or the chain from becoming blocked in the cutting
notch: if this should occur, disconnect the machine from the
main electricitysupply and try to raise the trunk using an
appropriate tool as a lever; do not attempt to free the
machine by shaking or pulling as this could cause damage or
injury.
- situations that can lead to kickback reactions.
- using the product above shoulder height.
- cutting wood with foreign objects e.g. nails.
Never use the machine in earth or stones, this leads to
immediate wear of the chain.
During machine use:
- When cutting on sloping ground, always work uphill of the trunk
to avoid being hit if the trunk should roll downhill.
- When felling trees, always finish the job: a partially cut tree could
break and fall.
- At the end of each cutting operation the user will notice a
considerable change in the strength necessary for controlling the
machine. Great care must be taken not to loose control.
Cutting action by pulling the chain (from top to bottom)
lead to dangerous sudden movement of the machine towards the
trunk with consequential loss of control. Where possible, use the
spiked bumper during cutting operations.
Cutting action pushing the chain (from bottom to top)
to the danger of a sudden movement of the machine in the
direction of the user, with the risk of hitting the user, or an impact
of the "kickback danger zone" on the trunk resulting in strong
kickback; extreme care must be taken when cutting in this
manner.
The safest method for using the machine, is to block the log on a
sawhorse, cutting from top to bottom, on the portion outside the
33
sawhorse .
Spiked bumper use.
Where possible, use the spiked bumper to ensure safer cutting
action: plant it in the bark or surface of the trunk in order to main-
tain more control over the machine.
