WORKING TECHNIQUES

Felling

WARNING! Unless you have special

! training we advise you not to fell trees with a diameter larger than the bar length of your saw!

Felling is done using three cuts. First you make the directional cuts, which consist of the top cut and the bottom cut, then you finish with the felling cut. By placing these cuts correctly you can control the felling direction very accurately.

Directional cuts

To make the directional cuts you begin with the top cut. Stand to the right of the tree and cut on the pull stroke.

Next make the bottom cut so that it finishes exactly at the end of the top cut.

The directional cuts should run 1/4 of the diameter through the trunk and the angle between the top cut and bottom cut should be 45°.

The line where the two cuts meet is called the directional cut line. This line should be perfectly horizontal and at right angles (90°) to the chosen felling direction.

Felling cut

The felling cut is made from the opposite side of the tree and it must be perfectly horizontal. Stand on the left side of the tree and cut on the pull stroke.

Make the felling cut about 1.5-2 inches (3-5 cm) above the bottom directional cut.

Finish the felling cut parallel with the directional cut line so that the distance between them is at least 1/10 of the trunk diameter. The uncut section of the trunk is called the felling hinge.

The felling hinge controls the direction that the tree falls in.

All control over the felling direction is lost if the felling hinge is too narrow or non-existent, or if the directional cuts and felling cut are badly placed.

When the felling cut and directional cut are complete the tree should start to fall by itself or with the aid of a felling wedge or breaking bar.

We recommend that you use a bar that is longer than the diameter of the tree, so that you can make the felling cut and directional cuts with single cutting strokes. See instructions under the heading Technical data section to

This makes the 576 XP EPA III not only high-performing but also environmentally friendly, meeting stringent EPA emission requirements.

The 570 EPA III, slightly smaller at 65.1cc, still boasts impressive power and torque, making it suitable for a variety of cutting tasks. This model is also equipped with the X-Torq technology, offering fuel efficiency and reduced emissions. It’s tailored for users who need a reliable chainsaw for medium to heavy-duty jobs, providing both power and ease of use.

Both models feature an Air Injection system that uses centrifugal force to remove larger dust and debris particles before they reach the air filter. This prolongs the life of the engine and reduces maintenance, enabling users to focus on the job at hand rather than frequent servicing.

Additionally, the Husqvarna 576 XP EPA III includes Smart Start technology, which ensures quick and effortless starting. The fuel pump and choke are designed to work in harmony, making it easier to start the saw with minimal effort.
