GASOLINE CHAIN SAW
WARNING!
When felling a tree is on a slope, the operator must stand higher on the slope as the felling tree
may roll down.
NOTE: The direction of fell is determined by the notch. Before making the cuts, assess the distribution of the
large branches, the center of gravity of the crown, and the natural slope of the tree to determine the direction
of tree felling.
WARNING!
Do not fell a tree in high or changing winds and if there is a risk of property damage. Do not fell
a tree if there is a risk of damage to wires. Coordinate felling with utilities and professionals.
Felling a tree
Usually felling a tree consists of two basic operations: notching (C) and making the final cut (D). Start the
notching (C) on the side of the tree that is in the intended direction of fall (E). Make sure that the notch does
not go too deep into the trunk. The notch (C) must be made so that a sufficiently thick and strong part of the
trunk (F) is left uncut. The notch must be wide enough to completely guide the falling of the tree when felling.
Warning! Do not walk in front of a tree that has already been notched. The final cut (D) is made on the back
side of the tree 3-5 cm above the horizontal base of the notch (C) (fig. 15).
Never cut the trunk all the way down. Always leave an adequately thick and strong part of the trunk (F) uncut.
This uncut part prevents the tree from falling prematurely and guides it when it falls. If you cut the trunk all
the way down, you will lose control over the direction of the fall. Place a wedge or lever in the cut before the
tree becomes unstable and begins to move. This way, you will prevent the bar from jamming in the cut if you
have misjudged the direction of fall. Before you fell the tree, make sure that no one is in the fall area of the
tree.
WARNING!
Before making the final cut, always make sure there are no animals or any objects in the work area.
Final Cut
Use wooden or plastic wedges (A) to prevent the bar or chain (B) from jamming in the cut. The wedges also
control the felling (fig. 16).
