Saw alignment – how to aim
To ensure felling accuracy, make sure that the line of sight of the saw is adjusted to suit the length of the tree you plan to fell.
Place the saw on a stump or similar surface and measure the distance from the stump in line with the tree’s height, for example: 15 m.
Tie a cord at a point 15 m away from the saw and pull the cord up to the middle of the guide bar. Adjust the position of the saw ensuring that the angle between the cord and guide bar is exactly 90 degrees. Use a set square or similar guide.
Now move the stretched cord so that it lies across the saw’s line of sight. If the two lines coincide, this means that the saw’s line of sight is exactly at 15 m.
If the lines do not match, you can make a new line of sight by drawing with a felt pen along the cord on the saw’s engine housing. This means you can adjust the saw’s line of sight to the tree length you usually fell.
How to get an even hinge
To get a perfectly smooth hinge, you can use this alignment method when you make the felling cut as well. When you saw up to the hinge from behind, you aim towards the same point as when you cut the directional notch. Both sides of the hinge are now exactly parallel.
