9.11 CROSS CUTTING/BUCKING
(FIGS.30 – 32)
Refer to general safety instructions for preparatory
and specific warnings.
– Regardless of the supporting method, when
cross cutting the compression face of the timber
must be initially cut followed by a secondary cut
from the other side to meet completing the cut.
The initial cut should be one third the diameter
and the secondary cut two thirds.
– Incorrectly assessing the tension can result in the
chain pinching or the timber splintering.
– For smaller logs always employ the use of a log
saw stand/horse. Smaller logs must be secured
before cutting commences as the chain speed
can cause the log to move and possible kick up.
– Use the spiked bumper to obtain a firm grip and
leverage while performing all cuts.
9.12 SAW CHAIN
– The chain saw is designed for cutting timber
only. Do not allow the chain to come into
contact with the ground as dirt and soil will dull
the chain almost immediately. Hard wood will
also rapidly dull the chain.
– When the chain is properly sharpened, work will
not be tiring, the cutting yield is high, and there
is no abnormal wear on the mechanical parts or
the bar.
