WORKING TECHNIQUES

Remove any undergrowth from the base of the tree and check the area for obstacles (stones, branches, holes, etc.) so that you have a clear path of retreat when the tree starts to fall.

Your path of retreat should be roughly 135 degrees away from the intended felling direction.

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°.

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

Set the spike bumper (if one is fitted) just behind the felling hinge. Use full throttle and bring the bar and chain slowly into the tree. Make sure the tree does not start to move in the opposite direction to your intended felling direction. Drive a wedge or breaking bar into the cut as soon as it is deep enough.

570, 575XP specifications

The Husqvarna 570 and 575XP chainsaws are remarkable tools designed for professional logger and forestry applications. Built for performance, durability, and ease of use, both models are engineered to handle the demands of heavy-duty cutting tasks while delivering outstanding power-to-weight ratios.

One of the standout features of the Husqvarna 570 is its X-Torq engine technology, which is designed to provide increased power while reducing fuel consumption and emissions. This engine technology allows the chainsaw to operate more efficiently, making it an environmentally friendly choice for users who are conscious about their impact on nature. The 575XP model also comes equipped with the X-Torq engine, delivering exceptional performance in a compact design.

Both models feature Husqvarna’s Air Injection system, which helps to minimize wear and tear by filtering out larger particles before they reach the air filter. This not only extends the life of the air filter but also allows for longer operating times between cleanings, thus improving overall efficiency.

The ergonomic design of the Husqvarna 570 and 575XP enhances operator comfort and control. The chainsaws come with a low-vibration system, which significantly reduces vibrations felt by the operator, making extended use more comfortable. The front and rear handles are designed for optimal grip, allowing for better maneuverability and reducing operator fatigue during prolonged cutting sessions.

Another key characteristic is the quick-release air filter, which allows for easy access for maintenance. This feature is particularly beneficial for professionals who need to ensure their equipment remains in peak condition.

In terms of safety, both models include a chain brake that provides instant stopping capabilities for added security during operation. This is a crucial feature when working in potentially hazardous environments.

With their combination of innovative technologies, ergonomic design, and robust performance, the Husqvarna 570 and 575XP chainsaws stand out in the market as reliable tools for professionals needing efficiency and power. Whether tackling large trees or performing forestry maintenance, these chainsaws are designed to deliver exceptional results.
