Freeing a tree that has fallen badly

Freeing a ”trapped tree”

It is very dangerous to remove a trapped tree and there is high accident risk.

Never try to fell the tree that is trapped.

Never work in the risk zone of the hanging trapped tree.

The safest method is to use a winch.

•Tractor-mounted

•Portable

Cutting trees and branches that are in tension

Preparations: Work out which side is in tension and where the point of maximum tension is (i.e. where it would break if it was bent even more).

Decide which is the safest way to release the tension and whether you are able to do it safely. In complicated situations the only safe method is to put aside your chain saw and use a winch.

General advice:

Position yourself so that you will be clear of the tree or branch when the tension is released.

Make one or more cuts at or near the point of maximum tension. Make as many cuts of sufficient depth as necessary to reduce the tension and make the tree or branch break at the point of maximum tension.

Never cut straight through a tree or branch that is in tension!

If you must cut across tree/limb, make two to three cuts, one inch apart, one to two inches deep.

Continue to cut deeper until tree/limb bends and tension is released.

Cut tree/limb from outside the bend, after tension has been released.

How to avoid kickback

!

WARNING! Kickback can happen very

suddenly and violently; kicking the chain

 

 

saw, bar and chain back at the user. If

 

this happens when the chain is moving it

 

can cause very serious, even fatal

 

injuries. It is vital you understand what

 

causes kickback and that you can avoid

 

it by taking care and using the right

 

working technique.

What is kickback?

The word kickback is used to describe the sudden reaction that causes the chain saw and bar to jump off an object when the upper quadrant of the tip of the bar, known as the kickback zone, touches an object.

Kickback always occurs in the cutting plane of the bar. Normally the chain saw and bar are thrown backwards and upwards towards the user. However, the chain saw may move in a different direction depending on the way it was being used when the kickback zone of the bar touched the object.

The Husqvarna 460 and 455 series chainsaws are some of the most popular models in their class, recognized for their reliability, performance, and advanced technology. These machines are designed to meet the demands of both professionals and enthusiasts who require powerful tools for cutting firewood, felling trees, or performing tree maintenance.

The Husqvarna 460 is equipped with a robust 60.3 cc engine that delivers impressive power and efficiency. With a power output of approximately 3.6 kW, this chainsaw is capable of handling ambitious cutting tasks with ease. The design of the 460 includes a low-vibration system that significantly reduces operator fatigue during extended use. This is achieved through effective isolating features that dampen vibrations transferred to the user's hands, allowing for more comfortable operation over longer periods.

One of the standout features of the Husqvarna 460 is its X-Torq engine technology. This innovative design reduces fuel consumption by up to 20% while also decreasing harmful exhaust emissions. This is increasingly important for environmentally conscious users, as it allows for a greener operation without compromising performance. The chainsaw is also equipped with an air injection system that effectively removes larger particles from the air before they reach the filtration system, ensuring cleaner air intake and extending the lifespan of the air filter.

On the other hand, the Husqvarna 455 Rancher is another exceptional model known for its versatility and robust design. Featuring a slightly smaller 55.5 cc engine, it offers a solid power output of around 2.6 kW, making it suitable for a wide range of tasks from cutting firewood to clearing brush. The 455 Rancher shares many of the same technological advancements as the 460, including the X-Torq engine and low-vibration technology, providing users with similar benefits in terms of efficiency and comfort.

Both models feature an adjustable oil pump for better chain lubrication, ensuring smooth operation and prolonging the chain's life. Additionally, the easy access air filter and tool-less chain tensioning allow for quick maintenance and adjustments in the field, making them user-friendly choices.

Overall, the Husqvarna 460 and 455 series chainsaws combine power, efficiency, and advanced technology, catering to the needs of both casual users and professionals alike. Their thoughtful design and robust performance establish them as reliable tools in any cutting task, making them a top choice for those in need of high-quality chainsaws.
