position the saw at a flat angle.
Attention!

tensioned!
- Only use impeccable chainsaws!
- Work with a correctly-sharpened saw chain!
- Never cut with the upper edge or the tip of the
saw bar!
- Always hold the chainsaw tightly with both

sometimes reacts in an uncontrolled manner. This
may result in severe injury or even in death. Only
trained specialists are allowed to carry out such
work.
