24 EN Instructions for proper use
ATTENTION! Beginning chain saw users should start getting experience with saw cutting of
supported trunks, e.g. on a wooden saw-horse.
ATTENTION! We recommend the users having no experience not to fell the trunks with
larger diameter than the guide length of their saw.
Dangerous zone
Dangerous zones are in immediate proximity of trees, within the distance that is the 2.5
multiple of tree height. Make sure that no person gets into the zone throughout felling.
Fell direction
Before tree felling remove any foreign objects from the work zone that could make felling and
subsequent lopping more difficult. The key prerequisite of safe work is free movement and
stable posture.
It is also important to prevent two trees from getting stuck. A stuck tree is very dangerous.
Even though you determine the direction of tree fall, always anticipate the possibility that the
tree falls somewhere else.
Tree fall direction is effected also by other factors such as natural tree lean, wind direction,
location and density of branches, or snow.
After all these factors are considered you see that you have no choice and your preferred, in
theory planned fall direction is not feasible.
Another key factor effecting your personal safety is possible existence of dry branches that
could jeopardize your safety throughout felling.
Sawing through of standing tree branches / Retreat zone
Remove any branches around tree base that could obstruct your work. The safest way is to
cut from top to bottom while tree trunk should be between yourself and saw chain. Never cut
the branches that are above the level of your shoulders. Clean undergrowth around the tree
and determine your retreat and escape zone taking into account impending obstacles (stones,
branches, holes, etc.). Your retreat zone must be oriented under the angle of approx. 135°
backwards from the falling tree.
Felling
Felling is done through three cuts. So called „upper cut“, then so called „lower“ or „horizontal“
cut make so called „notch“ that is determining for the direction of tree fall. The final cut is so
called „felling cut“ after which the tree fells.
