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 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 advance the chain/bar 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.

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.

385XP specifications

The Husqvarna 385XP is a powerful and versatile chainsaw, designed to meet the demands of professional loggers and landowners alike. Known for its exceptional performance and reliability, this model is engineered for heavy-duty tasks, making it a popular choice among forestry professionals and those requiring robust cutting tools.

One of the standout features of the 385XP is its impressive engine performance. The chainsaw is equipped with a 70.7 cc, 4.2 horsepower X-Torq engine, which not only delivers high power output but also ensures lower fuel consumption and reduced emissions, making it environmentally friendly without sacrificing performance. The innovative X-Torq technology allows for optimal combustion, enabling the chainsaw to run smoother and more efficiently.

The design of the Husqvarna 385XP focuses on user comfort and control. It features an ergonomic handle that reduces vibrations, enhancing the operator's comfort during extended use. The chainsaw's anti-vibration system minimizes the impact of vibrations on the user's hands, allowing for longer periods of operation without fatigue. This is crucial for professionals who spend hours in the field.

Another important technological aspect of the 385XP is its easily adjustable chain tensioning system, which simplifies adjustments and maintenance. The side-mounted chain tensioner allows users to make quick changes without the need for additional tools, ensuring that they can focus on the job at hand rather than fussing with equipment.

The 385XP is equipped with a high-quality cutting bar and chain, designed for durability and efficiency. The chainsaw features a 20-inch bar that provides ample cutting capacity, allowing for precise cuts in a variety of wood types. Its sharp chain ensures clean cuts with minimal kickback, enhancing safety and effectiveness when tackling larger logs or dense trees.

Another notable feature is the Air Injection system, which utilizes centrifugal force to remove larger dust and debris particles before they reach the air filter. This prolongs the filter’s life and decreases maintenance requirements, allowing users to spend more time working rather than cleaning.

In conclusion, the Husqvarna 385XP is a reliable chainsaw that combines power, efficiency, and user comfort. Its cutting-edge technologies, durable construction, and ease of use make it an ideal choice for professionals in the forestry industry and skilled homeowners alike.
