ASSEMBLY
Correct height
Adjust the shoulder strap so that the cutting attachment is
parallel to the ground.
Correct balance
Let the cutting attachment rest lightly on the ground. If you
use a saw blade it should balance about 10 cm above the
ground to prevent contact with stones and the like. Adjust the
position of the suspension ring to balance the clearing saw
correctly.
