Start the chain saw only after having assembled it com-
pletely and inspected.

10

fuelled the saw.
Make sure you have a good footing, and place the saw on the
ground in such a way that the chain is not touching anything.
Engage the chain brake (lock).
Hold the tubular handle tightly with one hand and press the
chain saw to the ground.
Steady the rear handle by standing in the hand guard.
