	Cutting technique
	The technique described be-
	low is of a general character.
	1. Support the work piece
		in such a way that you
		can predict what will
		happen and so it will not
		pinch.
	2. Always cut at full throttle.
	3. Start cutting gently, do
		not force or squeeze the
		chain in.
	4. Use a high chain speed.
	5. Move the chain slowly
		backwards and forwards.

! WARNING!

Under all circumstances avoid cutting using the side of the chain; it will almost certainly be damaged, break and can cause immense damage. Only use the cutting section.

! WARNING!

Do not lean the saw to the side, this can cause the chain to jam or break with personal injury as a consequence.
