WORKING TECHNIQUES

Cutting with the bottom edge of the bar, i.e. from the top of the object downwards, is known as cutting with a pulling chain. In this case the chain saw pulls itself towards the tree and the front edge of the chain saw body rests naturally on the trunk when cutting. Cutting with a pulling chain gives the operator better control over the chain saw and the position of the kickback zone.

10Follow the instructions on sharpening and maintaining your bar and chain. When you replace the bar and chain use only combinations that are recommended by us. See instructions under the headings Cutting equipment and Technical data.

Basic cutting technique

General

Always use full throttle when cutting!

Reduce the speed to idle after every cut (running the engine for too long at full throttle without any load, i.e. without any resistance from the chain during cutting, can lead to serious engine damage).

Cutting from above = Cutting with a pulling chain.

Cutting from below = Cutting with pushing chain.

Cutting with a pushing chain increases the risk of kickback. See instructions under the heading How to avoid kickback.

Terms

Cutting = General term for cutting through wood. Limbing = Cutting branches off a felled tree.

Splitting = When the object you are cutting breaks off before the cut is complete.

There are five important factors you should consider before making a cut:

1 Make sure the cutting equipment will not jam in the cut.

2 Make sure the object you are cutting will not split.

3Make sure the chain will not strike the ground or any other object during or after cutting.

4 Is there a risk of kickback?

5Do the conditions and surrounding terrain affect how safely you can stand and move about?

Two factors decide whether the chain will jam or the object that you are cutting will split: the first is how the object is supported before and after cutting, and the second is whether it is in tension.

In most cases you can avoid these problems by cutting in two stages; from the top and from the bottom.You need to support the object so that it will not trap the chain or split during cutting.

WARNING! If the chain jams in the cut: stop

!the engine! Don’t try to pull the chain saw free. If you do you may be injured by the chain when the chain saw suddenly breaks free. Use a lever to open up the cut and free the chain saw.

The following instructions describe how to handle the common situations you are likely to encounter when using a chain saw.

Cutting

The log is lying on the ground. There is little risk of the chain jamming or the object splitting. However there is a risk that the chain will touch the ground when you finish the cut.

Cut all the way through the log from above. Avoid letting the chain touch the ground as you finish the cut. Maintain full throttle but be prepared for what might happen.

-If it is possible (can you turn the log?) stop cutting about 2/ 3 of the way through the log.

- Turn the log and finish the cut from the opposite side.

CS 2135T specifications

The Jonsered CS 2135T is a highly regarded chainsaw designed for professionals and serious enthusiasts alike. Renowned for its robust performance and ergonomic design, the CS 2135T stands out in the competitive field of power tools.

One of the main features of the Jonsered CS 2135T is its powerful engine. It is equipped with a 35cc two-stroke engine that delivers excellent power-to-weight ratio. This makes it particularly useful for tasks that require high performance, such as felling trees or cutting firewood. Additionally, the engine is designed with a reliable starting mechanism, ensuring that users can get to work quickly without frustration.

The CS 2135T also employs advanced technology to enhance its efficiency and ease of use. One notable technology is the Clean Power engine system, which reduces harmful emissions while improving fuel efficiency. This is particularly important for users who are conscious about environmental impact and want to minimize their carbon footprint while working.

Another key feature is the Air Injection centrifugal air cleaning system. This system reduces the amount of debris that enters the air filter, prolonging the lifespan of the filter and maintaining optimal engine performance. As a result, users can expect longer filter intervals, which translates to less maintenance work.

Ergonomics play a significant role in the design of the CS 2135T. The chainsaw is equipped with an anti-vibration system that minimizes vibrations felt by the user, making it more comfortable to operate over extended periods. The handles are designed for a secure grip, providing users with better control and reducing fatigue during use.

Safety is also a priority with the Jonsered CS 2135T. It features a chain brake that acts quickly to stop the chain in the event of kickback, protecting the operator from potential injuries. Additionally, the transparent fuel tank allows users to easily monitor fuel levels, preventing unexpected run-outs during work.

In summary, the Jonsered CS 2135T is a high-performance chainsaw that excels in power, efficiency, ergonomics, and safety. Its combination of advanced technologies, user-friendly features, and robust design makes it an excellent choice for anyone looking to tackle demanding cutting tasks with confidence. Whether you're a professional lumberjack or a homeowner looking for a reliable tool, the CS 2135T is built to deliver exceptional results.
