Do the conditions and surrounding terrain affect how
safely you can stand and move about?
safely you can stand and move about?

that you are cutting will split: the first is how the object is
supported before and after cutting, and the second is
whether it is in tension.
that you are cutting will split: the first is how the object is
supported before and after cutting, and the second is

In most cases you can avoid these problems by cutting in

during cutting.

If it is possible (can you turn the log?) stop cutting about

IMPORTANT! If the chain jams in the cut: stop the
engine! Don’t try to pull the chain saw free. If you do you
may be injured by the chain when the chain saw
suddenly breaks free. Use a lever to open up the cut and
free the chain saw.

WARNING! Never attempt to cut logs
while they are in a pile or when a couple
of logs are lying together. Such
procedures drastically increase the risk
of kickback which can result in a serious
or fatal injury.
