SAFETY INSTRUCTIONS

2 The log is supported at one end. There is a high risk that it will split.

AStart by cutting from below (about 1/3 of the way through).

BFinish by cutting from above so that the two cuts meet.

3 Tree felling technique

It takes a lot of experience to fell a tree. Inexperienced users of chain saws should not fell trees. NEVER ATTEMPT A TASK YOU ARE UNSURE OF.

A Safe distance

The safe distance between a tree that is to be felled and anyone else working nearby is at least 21/2 tree lengths. Make sure that no-one else is in this "risk zone" before or during felling.

3 The log is supported at both ends. There is a high risk that the chain will jam.

AStart by cutting from above (about 1/3 of the way through).

BFinish by cutting from below so that the two cuts meet.

Limbing

When limbing thick branches you should use the same approach as for cutting.

Cut difficult branches piece by piece.

B Felling direction

The aim is to fell the tree in the best possible position for subsequent limbing and cross-cutting. You want it to fall on ground where you can move about safely.

The main point to avoid is letting the tree fall onto another tree. It can be both difficult and dangerous to remove a tree in such a position (see point 4 in this section).

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

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.

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

Additionally, the CS2163 incorporates the Smart Start technology that reduces the resistance in the starter cord, allowing users to start the saw with minimal effort.

The CS2171, on the other hand, is a more advanced model designed for heavy-duty applications. This saw comes with a 3.4 kW engine and boasts a larger cutting capacity, making it perfect for professional users who tackle more demanding tasks. Its X-Torq engine design significantly lowers fuel consumption and emissions, aligning with environmental standards while delivering exceptional power. The CS2171 also features an anti-vibration system that enhances user comfort during extended cutting sessions, therefore maximizing productivity without sacrificing ease of use.

The CS2165 occupies a sweet spot between the CS2163 and CS2171, offering a balance of power and efficiency. Powered by a 3.2 kW engine, it provides ample performance for most tasks while still being lightweight for easy maneuverability. This model includes the same Quick-Release Air Filter found in the CS2163, making maintenance a breeze. The CS2165 also features an adjustable oil pump, allowing users to customize the oil flow to the chain based on their specific cutting needs, enhancing the longevity of both the saw and the chain.

All three models prioritize user safety, featuring a chain brake system that quickly halts the chain in case of kickback. Furthermore, the ergonomic design of the handles offers a comfortable grip, reducing fatigue during longer cutting sessions.
