To maintain complete control when
cutting through, release the cutting
pressure near the end of the cut without
relaxing the grip on the chainsaw
handles. Don't let the chain contact the
ground. After completing the cut, wait
for the saw chain to stop before you
move the chainsaw. Always stop the
motor before moving from tree to tree.
