– Particular attention must be given when sawing side-
wards, slanted or during length cuts, as the gripping teeth
(12) usually can not be applied.
Cutting Logs (see figures F)
– Always secure the logs before cutting.
– Always cut the logs beyond the secured points to prevent
the log from closing in and causing the chain to get
jammed.
– Never allow the saw chain to make contact with the
ground or cutting equipment.
– Be careful not to trip over tree stumps, branches, roots,
etc.
