WORKING TECHNIQUES

Tree felling technique

IMPORTANT! It takes a lot of experience to fell a tree. Inexperienced users of chain saws should not fell trees. Do not attempt any task beyond your experience level!

Safe distance

The safe distance between a tree that is to be felled and anyone else working nearby is at least 2 1/2 tree lengths. Make sure that no-one else is in this ”risk zone” before or during felling.

Felling direction

The aim is to fell the tree in a position where you can limb and cross-cut the log as easily as possible. You want it to fall in a location where you can stand and move about safely.

Once you have decided which way you want the tree to fall you must judge which way the tree would fall naturally.

Several factors affect this:

Lean of the tree

Bend

Wind direction

Arrangement of branches

Weight of snow

Obstacles within the reach of the tree: for example, other trees, power lines, roads and buildings.

Look for signs of damage and rot in the stem, this makes it more probably that the tree will break and start to fall before you expect it to.

The main point to avoid is letting the tree fall onto another tree. It is very dangerous to remove a trapped tree and there is high accident risk. See instructions under the heading Freeing a tree that has fallen badly.

IMPORTANT! During critical felling operations, hearing protectors should be lifted immediately when sawing is completed so that sounds and warning signals can be heard.

Clearing the trunk and preparing your retreat

Delimb the stem up to shoulder height. It is safer to work from the top down and to have the tree between you and the saw.

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.

You may find you are forced to let the tree fall in its natural direction because it is impossible or dangerous to try to make it fall in the direction you first intended.

Another very important factor, which does not affect the felling direction but does affect your safety, is to make sure the tree has no damaged or dead branches that might break off and hit you during felling.

1152353-95, 570 EPA III, 576 XP EPA III specifications

The Husqvarna 576 XP EPA III and 570 EPA III chainsaws exemplify innovation in outdoor power equipment, designed for the demanding user who requires high performance and reliability. These models are ideal for professional loggers and landowners alike, combining power, efficiency, and advanced technology.

One of the standout features of the Husqvarna 576 XP EPA III is its powerful 72.2cc engine, which delivers exceptional cutting performance while maintaining low fuel consumption. This model incorporates the X-Torq technology, which reduces fuel consumption by up to 20% and decreases harmful exhaust emissions by up to 75%. 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.
