TREE CUTTING - ONLY AFTER APPROPRIATE TRAINING
WARNING: Beware of broken or dead branches that could fall during sawing and cause serious injuries.
- Do not cut near buildings or electrical wires unless you know in which direction the sawn tree could fall.
- Do not work at night, as you will not be able to see properly, or during rain, snow or storm, because then
it is difficult to predict the direction in which the tree could fall.
- Plan your work in advance.
- The work area around the tree should be clean so that you have firm support.
- The user should always stand on the top of the terrain, as the tree is expected to roll or slide after felling.
The direction of a tree fall can be affected by the following conditions:
•
Wind direction and speed.
•
Tree inclination. The slope is not always visible due to uneven or sloping terrain.
•
Determine the inclination of the tree with a spirit level.
•
Growing branches (and therefore the weight) on one side only.
•
Surrounding trees and obstacles.
•
- If two or more persons are involved in sawing and felling, the distance between the persons
performing the felling and sawing should be at least twice the height of the tree to be felled. When
felling trees, make sure that other people are not endangered, that the power lines are not affected
and that no material damage is caused. If the tree comes into contact with the power line, the energy
company must be notified immediately.
•
- Check for decomposition and rot. If the trunk is rotten, it may suddenly collapse and fall on you.
Make sure there is enough space for the tree to fall safely. Keep a distance of 2 1/2 the length of the
tree from the nearest person or other objects. Engine noise can drown out the warning call.
•
- Remove dirt, stones, loose bark, nails, staples and wires from the tree where you are going to saw.
KEEP CLEAR THE ESCAPE WAY
- An escape route must be planned before excavation and cleaned if necessary.
- The escape route should lead obliquely from the back of the falling tree.
Point 1: Escape exit planning
Point 2: The position at which the tree falls
LARGE TREE CUTTING (DIAMETER 15 CM) - ONLY WITH APPROPRIATE TRAINING
- Cut down large trees using the notch method. In this case, the wedge is sawn from the side according to
the required direction of fall. After the incision is made on the other side of the tree, the tree falls in the
direction of the wedge.
- NOTE: If the tree has large supporting roots, they should be removed before the incision is made. If the saw
is used to remove the supporting roots, the chain should not touch the ground to prevent it from falling out.
FELLING A TREE
- Cut off a notch 1/3 of the diameter of the tree at right angles to the direction of fall. First, make a lower
horizontal cut of the notch. This will prevent the saw chain or guide bar from jamming when making the
second notch cut. Now remove the cut notch.
- You can then continue sawing on the opposite side of the tree. Make it approximately 5 cm above the center
of the notch.
- Make a descending cut parallel to the horizontal cut of the notch. In the case of a descending cut, only saw
to a depth to preserve the bridge (holding the wood), which can act as a hinge. The bridge prevents the tree
from turning and falling in the wrong direction. Do not saw across the bridge.
- NOTE: When a descending cut is made near the bridge, the tree should begin to fall. If it appears that the
tree may not fall in the desired direction or tilt back and catch the saw chain, stop the descending cut and
use wood, plastic or aluminum wedges to open the cut and tilt the tree in the desired direction to fall.
- When the tree starts to fall, remove the saw from the cut, switch it off, set it aside and leave the danger
zone along the planned escape route. Watch out for falling branches and don't trip.
- Watch for signs that the tree is starting to fall: the sounds of cracking, the expansion of the saw, or the
